Lt. James Montgomery Doohan (14th. Field Artillery Regiment, 3rd. Canadian Division)

 

Source: Pintrest

     At 0925 on June 6, 1944, the self-propelled guns (SPG) of the 14th. Field Artillery Regiment, 3rd. Canadian Division, put ashore on Juno Beach. The unit was equipped with the Priest, the British name for the U.S. built M7 105mm Howitzer Motor Carriage (HMC) which used M3 and M4 medium tank chassis as the foundation for the SPG. Each of the Priest self-propelled guns was laden down with crates of rifle, machine-gun, and mortar ammunition for the infantry. By 1100, the unit had moved inland and located firing positions to commence bombardment and fire support for Canadian infantry pushing forward off the beach. Included in the ranks of the 14th. Field Artillery Regiment was Lieutenant James Montgomery Doohan.

     In 1938, Doohan enrolled in the 102nd. Royal Canadian Army Cadets Corps at the age of 18. The RCAC, founded on July 25, 1879 and continuing to this day, is a quasi-military youth organization which is similar to the Junior Reserve Officers' Training Corps (JROTC) in the United States. He would not remain in the 102nd. RCAC Corps for long as when World War Two began, Doohan was quick to enlist, being accepted and sent to the 14th. (Midland) Field Battery, 2nd. Canadian Infantry Division. In May 1940, the division was posted to Iceland for garrison duty but this was quickly cut short and the unit was dispatched to England to augment the British Army who rightly feared that a German invasion was only a matter of time following the German victory in France. The 2nd. Canadian Infantry Division arrived in England in August 1940. During this time, Doohan rose to the rank of Sergeant before earning a slot in officer training school. After successfully completing the training, he was promoted to Lieutenant and transferred to the 14th. Field Artillery Regiment.

     Returning to Juno Beach, the Canadians made progress but there was an element of chaos and nerves as they pushed forward against the Germans. One example of this was when a captain of The Royal Winnipeg Rifles wanted artillery fire called down on a house and gun crews from one of the Royal Canadian Artillery units unlimbered their guns but forgot to remove the barrel covers and clean off the protective grease on the barrels and breeches before opening fire. The result was covers being shot down the road and the guns giving off voluminous clouds of smoke as the grease heated up and burned off. It was a case of nerves that almost cost Lt. Doohan his life...and at the hands of a fellow Canadian. Doohan's unit of 120 men, after battling towards Courselles-sur-Mer, had set up positions near the town. During the night, Doohan took a cigarette from a silver case that one of his brothers had given him and enjoyed a smoke while returning to his command post. Unfortunately, a nervous Bren gunner opened fire on Doohan, mistaking him for the enemy. He was struck a total of six times with four wounds to his leg, one through his right middle finger, and the sixth struck him in the chest. Had it not been for the cigarette case in the pocket of his field blouse, Doohan likely would not have survived. Doohan had to be evacuated from the front line and his finger was too mangled to save and so it had to be amputated. As he convalesced, Doohan attended the 40th. class of instruction for the Air Observation Pilot Course. During the training, he flew Taylorcraft Auster Mk. IV and Mk. V liaison and observation planes. Upon successful graduation, Doohan was assigned to the No. 666 Air Observation Post (AOP) Squadron, Royal Canadian Air Force. There, Doohan, now a Captain, retained his position as a artillery officer and flew in support of the 1st. Army Group, Royal Canadian Artillery. The small unit was stood up on March 5, 1945 and equipped with sixteen Auster Mk. V aircraft and Doohan was one of ten pilots. The unit departed England on May 28, 1945 and was posted to various locations in the Netherlands where it was ultimately disbanded in Apeldoorn, the Netherlands on October 31, 1945.

     The photograph of Lt. Doohan shows him wearing the 1940 Battledress as evidenced by the box pleats on the pockets and pocket flap covering the front buttons on the blouse as well as the map pocket on the trousers whose flap concealed the button closing the pocket. One both sleeves can be seen the rectangular patch, in French-gray (a light blue hue), that was the formation insignia for the 3rd. Canadian Division. Right above the insignia is the nation patch which read “Canada”. Around his right shoulder can be seen a lanyard, likely in red and/or blue, which was worn by officers of the 14th. Field Artillery Regiment. At the end of it was a whistle. Although not visible in this view, he wears two rank pips on each shoulder board to denote his rank and at least one other photograph of Doohan shows him with slip-on shoulder titles on each shoulder board, likely with R.C.A.C. (Royal Canadian Artillery Corps) stitched on them. On his cap is the badge of the Royal Canadian Artillery and the motto of “Quo fas et Gloria Ducunt” which means “Whither Right and Glory Lead” is written on a banner beneath a cannon with a crown above it. His belt, pistol holster, and ammunition pouch all appear to be the Pattern 1937 web equipment. His sidearm is most likely the .380 caliber Enfield No.2 revolver and the lanyard connected to the pistol grip is visible.

     Of course, James Montgomery Doohan is best remembered for playing Chief Engineer Montgomery "Scotty" Scott of the U.S.S. Enterprise (NCC-1701) from the Star Trek science-fiction franchise. Doohan died on July 20, 2005 at the age of 85.

Battle of Iwo Jima: M-2-4 Multiple Rocket Launcher Truck

Source: United States Marine Corps

     Positioned somewhere on the island of lwo Jima, a U.S. Marine Corps (USMC) rocket battery commences firing salvos of 4.5in. Beach Barrage Rockets (BBRs) towards Japanese positions. The 110mm rocket (4.5") was given the nickname "Old Faithful'' and originally, it was designed for the U.S. Navy to be launched from landing ships. In fact, the U.S. Navy deployed twelve such ships, the LSM(R) (Landing Ship Medium (Rocket)) class, to the Pacific Theater where they conducted ship-to-shore bombardments. 

     At the Battle of lwo Jima, there were two USMC rocket batteries, the 1st. Provisional Rocket Detachment and the 3rd. Provisional Rocket Detachment. The former supported the 4th. Marine Division while the latter supported the 5th. Marine Division. From the photograph itself, it isn't possible to tell which unit this is. 

     The vehicles are International Harvester M-2-4 1-ton, 4X4 cargo trucks which both the Navy and the USMC had been using since 1941. Fitted to the rear of the trucks were three, 12-rail Mk.7 rocket launchers which" allowed each truck to fire a full salvo of 36 rockets. Each battery was equipped with 12 trucks and so one battery could launch 432 rockets. 

     The truck nearest the camera has the name "Vis a Tergo" on the hood. This is a medical term meaning "a force acting from behind; a pushing or accelerating force." It would appear that the crew of "Vis a Tergo" did not secure the canvas bed/cab cover which is being whipped up by the exhaust of the rockets as they launch.

Russo-Ukrainian War: The 2A65 Msta-B 152mm Howitzer

Source: Alexey Konovalov/TASS

     In a well-prepared position, a Russian crew of a 2A65 Msta-B 152mm howitzer ready a round for firing. Named after the Msta River that flows through Novgorod and Tver Oblasts in Russia, the 2A65 first entered service in 1987. The “B” stands for “buksiruemyi” which translates to “towed”. In 2024, the International Institute for Strategic Studies estimated that Russian artillery units had a approximate total of 400 2A65 howitzers. To date, the Russians have lost 131 documented Msta-B howitzers with 78 being destroyed, 17 suffering damage, one abandoned, and the remainder having falling into Ukrainian hands.

     Speaking of damaged, the 2A65 in the photograph has clearly endured its fair share. It is missing the left gun shield and the remaining shield is peppered with what could be shrapnel damage which has caused rust to start. The wheels have been removed and what one sees beneath the gun shield is the pneumatic drum brake system for the right wheel. Finally, the howitzer is missing the spring-operated rammer. This is the reason the soldier behind the loader wields a stout stick which he will use to ram the projectile and powder charge into the breech.

     The caliber of the 2A65 is, specifically, 152.4mm and with the muzzle brake, the barrel is 26.8 feet long. The combat weight of the 2A65 is 7.5 tons. The howitzer uses a split trail carriage (here, almost buried in fine grain dirt) and the mounting permits a maximum elevation of 70 degrees to a maximum depression of 3.5 degrees. Traverse is limited to 28 degrees without moving the entire howitzer. All adjustments to gun direction are manual. Just visible on the front of the howitzer is a circular hydraulic firing jack which is lowered to add stabilization to the howitzer, augmenting the spade on each end of the trailing arms. With a full crew of 11 men, a Msta-B can achieve a 5 to 6 round a minute rate of fire. Usually, the tow vehicle is a KrAZ-260 or Ural 4320 6x6 truck though any vehicle with a tow hitch and capable of hauling the Msta-B can be utilized.

     While the Msta-B can fire any legacy 152mm projectile used by older howitzers, it primarily fires more modern munitions. The main projectile is the OF45 HE (High-Explosive) round and with a maximum charge, it can be fired out to a range of 15.3 miles. Speaking of charges, the gunner can select from three types depending on the engagement range. They are: OF73 (short range), OF58 (standard charge), and OF72 (maximum charge). For additional range, the base-bleed OF61 projectile can be utilized and this achieves a maximum range of 18 miles. Other munitions include the OF23 which contains 42 HEAT (High-Explosive Anti-Tank) submunitions which can penetrate 100mm of conventional (not rolled homogeneous) armor, the HS30 EW (Electronic Warfare) round which creates interference, and the 2K25 Krasnopol base-bleed, fin-stabilized, semi-automatic, laser-guided munition. The latter, however, requires forward observers to effectively use the round (by “painting” targets with lasers) and the effective firing range is 12 miles. A panoramic sight is used for indirect fire while a second sight is used if the Msta-B has to engage in direct fire.

     The Ukrainian Army also utilizes the Msta-B with some 70 noted as being in service in the 2024 “The Military Balance” report issued by the International Institute for Strategic Studies. Of these, to date, 8 have been lost with 3 destroyed, 2 damaged, 2 abandoned, and one captured by Russian Forces.

Artillerie-Panzerbeobachtungswagen III, 75. Panzer-Artillerie-Regiment

Source: Author's collection

     As World War Two continued, the German military utilized more and more self-propelled artillery though such guns were never able to fully replace horse-drawn or those guns drawn by half-tracks or other soft-skinned vehicles. Of course, for artillery of any kind to be truly effective during the war, it required forward observers who would watch the fall of the rounds and radio back corrections to the firing batteries to ensure that as much of the incoming fire was as close to on-target as possible and thus maximize the destruction. These forward observers were often small teams on foot or moved about the battlefield in lightly armored vehicles such as armored cars or light tanks. By 1943, such vehicles had a very limited lifespan. Typically artillery was used defensively to break up an attack or was used on the offense to soften up the enemy prior to committing ground troops. Either way, it meant the forward observers had to be in the vicinity of the action in order to witness the incoming fire missions and correct as needed. Thus, it was seen that something better was needed to support the self-propelled artillery batteries and give forward observers the means to survive the front lines. The initial answer was the Artillerie-Panzerbeobachtungswagen III (PzBeobWg III).

     The Artillery Tank Observation Vehicle III was, in reality, a stop-gap measure which was undertaken to provide such a vehicle while development of a purpose-built armored observation vehicle was conducted (something that did not happen). Using war-weary and obsolete Ausf E through Ausf H models of the Panzerkampfwagen III medium tank, several modifications were done to convert them to their new role. The biggest change was the removal of the main gun armament. In place of the main gun, a Maschínengewehr 34 (MG 34) in a ball mounting was fitted and provided with 1,500 rounds of ammunition. The weight savings by not having a main gun nor the associated shells allowed for the fitting of an additional 30mm of armor plate on the hull front and on the entire rear of the tank. In addition, a new gun mantlet replaced the original, increasing the thickness from 30mm to 50mm. A feature of this mantlet was the addition of a dummy gun fitted to the right of the MG 34. The hull machine-gun was removed and the hole for the machine-gun was fitted with a metal plug. For radio equipment to allow communication back to the battery, the PzBeobWg III was fitted with a Funkgerät 4 (FuG 4) and the FuG 8. The FuG 4 utilized a 2 meter tall star antenna though specifics about it are not well known. The FuG 8 was heavily used for divisional communication with later models using a 30 watt transmitter, MW receiver C, and had a frequency band of 835 to 3,000 kilocycles per second. It used a 8 meter tall mast antenna. The FuG 4 had a much shorter range, with a Wireless Telegraph (WT) range of 2.3 miles and a Radiotelephone (RT) range of 1.2 miles. The FuG 8, on the other hand had a WT range of 31.1 miles and a RT range of 6.2 miles. In all, 262 PzBeobWg III vehicles were constructed between February 1943 to April 1944 and two such vehicles were deployed to each Hummel (“Bumblebee”) or Wespe (“Wasp”) self-propelled gun batteries as supply permitted.

     The photograph was reportedly taken following the German defeat at the hands of the Soviets following Unternehmen Frühlingserwachen (Operation Spring Awakening) in mid-March 1945 near Lake Balaton, Hungary. If this is accurate, then the PzBeobWg III belonged to 75. Panzer-Artillerie-Regiment underneath the III. Panzerkorps, 6. Armee, Heeresgruppe Süd. This unit was equipped with “Wespe“ 10.5cm self-propelled guns on the Panzerkampfwagen II chassis. It is difficult to assess what model the PzBeobWg III shown was built on but given the late date in the war, it is likely an Ausf H version. The crew had secured three links of track to the front of the tank in an effort to increase the protection. Since the hull machine-gun was not fitted, the track covered where it had been but one can see a portion of the track missing to allow the driver to see through his vision block. Just visible are the schürzen (armored skirts) fitted to the turret and hull. The front part of the skirt on the hull can be made out to the right (as one looks at the photograph) of the Soviet soldier. The turret skirt is visible just behind the dummy gun mantlet. These skirts were designed to reduce the velocity or divert the trajectory of incoming kinetic rounds. In the upper, right corner of the photograph is the star antenna for the FuG 4 radio. 

     Of interest, however, is the dummy gun itself. The crew of this PzBeobWg III fashioned an entirely new dummy gun and fit it over the existing one. The likely reason for this is because the standard dummy gun gave the appearance of the far weaker short 5cm KwK L/42 or the 3.7cm KwK L/46.5. By adding the additional wooden mantlet sleeve and the longer wooden barrel with a muzzle brake, it gave the PzBeobWg III the appearance of a Panzerkampfwagen IV fitted with the potent 7.5cm KwK40 L/48 gun. This was made more so by the use of the schürzen which many late-war PzKpfw IV tanks were equipped with. In so doing, the elaborate wooden dummy gun assembly helped the PzBeobWg III blend in more and not be singled out. Of course, the Soviet soldier hefting the broken gun tube for the camera means it didn't make much of a difference for this PzBeobWg III.

Russo-Ukrainian War: The 2S19 Msta-S 152mm SPH

Source: Russian Defense Ministry Press Service

     Somewhere in Russian occupied Ukraine, a Russian 2S19 Msta-S 152mm SPH (Self-Propelled Howitzer) moves into a position on October 29, 2025. The symbol on the hull front, below the blurred image of the driver, is what is sometimes termed as a “theater tactical” symbol. These are used to identify Russian vehicles from Ukrainian ones since in many cases, both sides are using the same equipment. This particular theater tactical symbol first appeared in May 2024 on Russian vehicles during combat actions in Kharkiv Oblast.

     The 2S19 is liberally draped in rubber panels made from conveyor belts. Fairly easy to obtain, conveyor belts often find use as appliqué armor where they are cut into pieces and applied as best possible to combat vehicles. The main purpose is to offer a small measure of protection from HEAT (High-Explosive Anti-Tank) munitions. The turret of the 2S19 has a metal frame to which the panels are hung and a portion of that frame can be seen above the turret. A panel hangs down from the front of the 2S19, protecting the lower glacis while panels on the sides of the 2S19 hang almost to the ground. Atop the entire turret is a camouflage net. What could be a video camera can just be seen attached to the visible portion of the metal frame.

     Since the 2S19 isn't meant to be on the front lines, relying on the range of its howitzer to keep it further back from the majority of prowling FPV drones, it doesn't carry the extensive anti-drone defenses seen on vehicles much closer to the front. Such defenses include drone jammers, more extensive screen armor, explosive reactive armor blocks, and wire/cable “spike” armor.

Russo-Ukrainian War: The M114A1 155mm Howitzer

Source: Anatolii Stepanov (Reuters)

     Artillery units of the Ukrainian Army are fielding two artillery pieces whose service debut occured during World War Two. The first is the M101A1 105mm howitzer which first entered service with the U.S. Army in 1941. Lithuania, Portugal, and Slovenia have provided Ukraine with a combined total of 43 M101A1 howitzers between 2022 and 2024. The second is shown in action here in service with the 152nd. Jäger Brigade, the M114A1 155mm howitzer. The M114A1 first saw service with the U.S. Army in 1942 and despite the age, 21 countries still use the M114A1 with Turkey and Greece maintaining the largest stocks. In fact, the M114A1 shown in the photograph is a former Hellenic Army weapon. In early 2024, Greece and the Czech Republic entered into an agreement where the Czech Republic would purchase 70 M114A1 howitzers which were surplus to the Hellenic Army's needs. Upon completion of the sale, Greece will deliver the M114A1s to Ukraine. From appearances, this sale has completed but how many of the purchase have been delivered to date is not known.

     Captured by the cameraman in full recoil, the M114A1's barrel is 12.5 feet long and it uses a slow-cone, interrupted screw breech. This means that it takes two actions on the part of the gunner to open the breech rather then one action for a steep-cone type. The combat weight of the M114A1 is 5.6 tons and requires a crew of 11 men though operating the howitzer can be done with less crew if necessary. The M1A2 carriage is a split trail style and the gun mount permits a maximum barrel elevation of 63 degrees and in the right conditions, a maximum gun depression of 2 degrees. Traverse is limited to 25 degrees to the left and right of center. Elevation, depression, and traverse is all affected manually using cranks. Any additional traverse requires the entire howitzer to be repositioned. The only recoil reduction comes from the hydro-pneumatic mechanism as the M114A1 does not use a muzzle brake. The crew is provided with a minimal gun shield that offers a limited defense against some small arms fire and shell fragments.

     Despite the breech type, a trained crew can run 4 rounds through the M114A1 during burst firing. A sustained fire rate is 1 round every minute but not exceeding 40 rounds per hour. As a comparison, the M777 155mm howitzer, which entered U.S. Army service in 2005 and is in use by some Ukrainian artillery units, can maintain a sustained fire rate of between 2 to 4 rounds every minute and a burst fire of no more than 16 rounds in 2 minutes. Sighting is done using a M12 panoramic telescope.

     It is not known if the Ukrainian M114A1 howitzers will be firing RAP (Rocket Assisted Projectiles) munitions (on the assumption the venerable howitzer is not designed to withstand the breech pressures) and it certainly is not compatible with the M982 Excalibur guided projectile. It is unlikely that extended-range projectiles using base-bleed would be fired from the M114A1 and instead, would be reserved for more modern systems such as the M777. This, then, leaves the M107 HE (High-Explosive) projectile as the most likely ammunition to be issued to and used by M114A1 crews. The M107 has a weight of 90 pounds of which 15 pounds is composed of TNT. The ammunition is two-part, consisting of the M107 projectile and the propelling charge. The maximum charge, the M4A1, contains a base charge and four incremental charges. This collection of propellent powder weighs just under 14 pounds. Using the M4A1 charge, the M114A1 can fire the M107 shell out to a maximum range of 9.2 miles. As another comparison, the M777 can fire the same M107 shell to a maximum range of 13 miles. Against hard targets, a M107 shell fired from the M114A1 can penetrate a maximum of 488mm of concrete at a meet angle of 0 degrees at a range of 2.8 miles.

     To date, no Ukrainian M114A1 has been lost in action. The photograph was taken on October 15, 2025, the crew firing on Russian positions near Pokrovsk, Donetsk Oblast.

Russo-Ukrainian War: Artillerisystem 08 Archer 155mm SPH

Source: General Staff of the Armed Forces of Ukraine

     One of the more unique artillery systems in use by Ukrainian Army artillery units is shown here, the Artillerisystem 08. Better known simply as the Archer, this vehicle is in service with one of the four artillery battalions of the 43rd. Artillery Regiment “Hetman Taras Triasylo”. Sweden, as part of the country's military aid to Ukraine, has provided 8 Archer systems and in September 2025, pledged another 18 systems. Of the eight, one was damaged by a Russian drone attack on March 3, 2024 with a second destroyed on August 4, 2025. Designed by the Swedish company Bofors between 1995 and 2009, the Archer entered production in 2010, being built by BAE Systems AB. To date, only 48 Archer systems have rolled off the line with over twice that on purchase orders from the Latvian Land Forces, Swedish Army, and Ukrainian Army.

     The basis of the 34-ton Archer is the Volvo A30D articulated 6x6 vehicle chassis which is used in the civilian construction industry (usually as a dump truck). Power comes from a Volvo D9BACE3 inline-6, intercooled diesel engine with a turbocharger that develops 340 horsepower. This is mated to a Volvo PT1560 automatic planetary transmission with a 8-speed gearbox (6 forward, 2 reverse). Three Volvo AH64 axles feature transversal differential locks with full floating axle shafts. The driver can select 6x4 or 6x6 drive on the fly. The maximum road speed is 43 miles per hour while the top reverse speed is 8 miles per hour. 105 gallons of diesel fuel provide for a maximum operational range of 400 miles.

     Situated on the very back of the chassis is the heart of the Archer, a turret mounted Fälthaubits 77 (FH77) L/52 155mm howitzer. The turret is able to traverse a total of 170 degrees and elevate the gun to a maximum of 70 degrees. Total depression is 1 degree. Housed within the turret is a fully automatic gun loading system and electronic fuze setter. Total onboard ammunition is 21 shells with a total of 126 modular propellant charges. The shells have their own magazine while the propellant charges are in a separate magazine of 18 rows which contain 6 full charges and 1 half-charge. Once all of the ammunition is expended, it takes the crew 10 minutes to reload assuming they have the Archer-specific reloading device that moves ammunition from the accompanying munitions carrier into the magazines.

     The turret itself is unmanned and instead, the gunner operates it from the cab. A FCS (Fire Control System) utilizing NABK (NATO Armament Ballistic Kernel) software generates ballistic tables for any ammunition being used along with both tabular and graphical firing tables. The FCS also automates bringing the howitzer onto target, positioning the turret without manual guidance. This is assisted by a SAGEM Sigma 30 inertial navigation system (INS). The howitzer has several fire modes to include burst fire (3 rounds every 20 seconds), sustained fire (54 rounds every 35 minutes), bombardment (21 rounds in 3 minutes), and MRSI (Multiple Rounds Simultaneous Impact). With MRSI, the FCS calculates the trajectory then handles the firing of 4 to 6 rounds so that all rounds impact on the target at the same time. The Archer is compatible with any NATO standard 155mm projectile with standard HE (High-Explosive) shells having a range of around 19 miles, extended range HE shells reaching out to 25 miles, and M982 Excalibur guided shells can attain a range of 31 miles. If need be, the Archer can engage in direct fire, out to a range of 1.2 miles. Shell speed upon exiting the barrel is measured by a Weibel MVRS-700SC muzzle velocity radar. From the halt, the Archer can be ready to fire in under 30 seconds. Stability during fire missions is provided by two rear-mounted stabilizers. Likewise, the Archer can be ready to move to a new position, also in under 30 seconds.

     For local defense, a Vapenstation 01 RCWS (Remote Controlled Weapon Station) can be fitted to the cab roof. The Vapenstation 01 is the Swedish designation for the M151 Protector RCWS which can be fitted either with a Browning M2 12.7mm heavy machine-gun or a Mk.19 40mm automatic grenade launcher (among other weapon fits). While the Vapenstation 01 is not seen in the photograph, there are some Ukrainian Archers which use it.

     The Archer's cab (holding the 4 man crew) is protected by STANAG 4569 Level 3 steel armor which provides proof against 7.62x51mm AP (Armor-Piercing) ammunition at 30 meters as well as 155mm shell fragments from 60 meters. Below the cab, the Archer supports STANAG 4569 Level 2b mine protection which permits the Archer to survive the blast from a mine packed with at most 13 pounds of explosive. Air filters and a crew cab overpressure system provides NBC defense (Nuclear, Biological, Chemical). In the photograph, the Archer is covered by a Saab Barracuda MCS (Mobile Camouflage System) which consists of fitted panels which is a multi-spectral camouflage. It features a high UV reflectance, patterns that match NIR (Near IR) reflections of the surrounding environment, SWIR (Short-Wave IR) management by adjusting spectral reflections of the environment, TIR (Thermal IR) reduction (utilizing convection, reflection, radiation, and insulation), as well as providing protection against SAR (Synthetic Aperture Radar) systems.

300-Pounder (10") Parrott Rifle, Battery Strong, Morris Island: Down But Not Out

Source: Library of Congress

     Situated on Morris Island in South Carolina, its barrel broken, is one of only three 300-pounder Parrott rifles operated by Union forces during the Civil War. Part of Battery Strong, this particular Parrott rifle saw action during the Second Battle of Charleston Harbor which ran from July 18, 1863 until September 7, 1893 where it participated in the bombardment of Fort Wagner (also on Morris Island) which was defended by Confederate troops who had already defeated two Union assaults which attempted to take the fort.

     The Parrott rifle, designed by Captain Robert Parker Parrott, was heavily used by both Union and Confederate artillery forces. The 10-pounder Parrott rifle first appeared in 1860 and by 1862, larger Parrott rifles had appeared, to include the 20-pounder Parrott rifle (used as a field gun) and 30-pounder. In time, heavy artillery for siege warfare and bombardment saw the 100-pounder, 150-pounder, 200-pounder, and the rarest of them all, the 300-pounder Parrott rifle enter service by 1863.

     The Parrott rifle, regardless of caliber, was made of cast iron and this was chosen to extend the life of the rifling within the barrel. However, cast iron was brittle and was prone to splitting or cracking under the pressure created by the gasses of detonating gun powder. To reduce this risk, Parrott rifles had a wrought iron band around the breech. Parrott rifles were inexpensive, the 10-pounder only costing $187 to produce, and the Parrott rifle could be built quickly. Not surprisingly, the common 10-pounder and 20-pounder Parrott rifles were in widespread Union service. Despite the banding, the Parrott rifle was still susceptible to barrel bursts or damage.

     The 300-pounder (equivalent to a 10” caliber) had a length of 13 feet and a combat weight of 13.5 tons. Two primary shells were fired, one a sabot shell while the other was called a bolt. The sabot shell, a high-explosive munition, featured a metal ring (sabot) around the base of the shell and it was this ring that engaged the rifling within the barrel. Two fuzes were used, one being the Parrott time fuze while the other was a impact fuze. The Parrott time fuze consisted of a Zink plug in the nose of the sabot shell and within was a length of paper. The time delay until the shell exploded was derived by cutting the paper to a specific length. The impact fuze consisted of a percussion cap that was placed in the shell's nose and when the shell hit the target, the cap deformed and created a flame that set off the shell's charge. The bolt was a solid projectile and was mainly used to bludgeon through the armor of ironclad ships though it could also be used to smash into the stone and masonry walls of fortifications and shatter it. These shells had a weight between 222 to 300 pounds each and the typical powder charge weighed 26 pounds. The 300-pounder was muzzle loaded and though the crew size is not known, it was sizable. The 100-pounder Parrott rifle, as an example, required a crew of 17 men. With the barrel at a 30 degree elevation, the 300-pounder could hurl either a shell or bolt to a range of 5 miles.

     Returning to the 300-pounder in the photograph, on August 20, 1863, a shell burst towards the end of the barrel, blowing it apart. Exactly what unit was operating the Parrott rifle isn't known but it was either attached to a detachment from the 7th. Connecticut Infantry Regiment or was crewed by men from the regiment. This is because one Captain Sylvester Gray, who served with C Company, 7th. Connecticut, ordered the crew to take up tools and chisel and file away at the jagged end of the barrel until it was clear of any protrusions. With the remaining barrel unobstructed, the crew brought the Parrott rifle back into action with little loss in accuracy. 

     Fort Wagner held out, enduring near daily bombardment for two months, until September 6, 1863 when the remnants of the Confederate men within the fort (some 400 troops) abandoned it along with Morris Island, ceding it to Union forces.

Russo-Ukrainian War: "Office" of the 2S1 Gvozdika 122mm SPH

Source: inukraine.official on Instagram

     The “office” of a Ukrainian 2S1 Gvozdika (“Carnation”) 122mm SPH (Self-Propelled Howitzer), a screen shot from a social media video. The 2S1, first entering service in 1972, is the second oldest self-propelled gun currently in use with the Ukrainian Army. Only the 2S3 Akatsiya (“Acacia”) 152mm SPH is the oldest, having first entered service in 1971.

     The breech belongs to the vehicle's 2A18 122mm howitzer, a variant of the towed D-30 howitzer. The 2A18 uses a horizontal, sliding-wedge, semi-automatic breech. The latter means the empty shell case is automatically ejected from the breech after firing. One empty case can be seen on the turret floor. Above the breech are the howitzer's hydropneumatic recuperator system which assists in absorbing recoil energy after firing. The lever with the horizontal grip operates the breech while the more vertical positioned lever to the left of the breech with the round grip is a manual trigger for the howitzer. The curved plate above the howitzer is the barrel mantlet.

     Along the inside of the turret are racks for ready projectiles and propellant charge cases. All told, the turret holds 24 complete rounds (projectile + propellant case) while another 16 rounds are stored in the rear hull. Spent cases can be reused though they need to be returned to a ammunition manufacturer to effect the refurbishment. This includes a thorough cleaning followed by inspection for damage, deformity, or other flaws. After passing inspection, the case is provided with new primer and propellant charges.

     The loader's position is to the right of the gun and he is assisted with a power rammer whose tray and arm can just be seen at the far right of the image. The loader will first open the breech (it is closed in the image) then places the projectile into the tray. With a push, the loader slides the rammer apparatus so that it is lined up with the breech. After the loader hits the activation switch, the rammer engages and pushes the projectile into the breech. The loader next places the propellant case onto the tray, hits the activation switch, and the rammer pushes the case into the breech. At this point, the breech closes and the rammer apparatus automatically shifts to the right, out of the way of the breech. The howitzer is now ready to fire.

     The gunner sits to the left of the gun and he can just be seen at the very left edge of the image wearing a t-shirt (above and behind him is the commander). After quickly checking his targeting information, he pushes down on the vertical lever and this fires the howitzer. The empty propellant case is then ejected out of the breech and falls to the turret floor. The breech remains open, ready for the next shell.

     A trained crew can run up to 5 rounds per minute through the 2A18 but a more sustained rate of fire is between 1 to 2 rounds every minute.

Panzerhaubitze M109G (4. Batterie, Artillerielehrbataillon 145)

Source: Author's collection

     Most likely a publicity photograph, one gets a good view of the business end of a Bundeswehr Panzerhaubitze M109G self-propelled gun (SPG). Between 1964 and 1972, the Bundeswehr purchased a mixture of M109A1 and M109A2 SPGs from the United States. In two waves, the SPGs were sent to Rheinmetall AG who performed a myriad of improvements and adaptations to make them suitable for German service. The original 155mm howitzer was replaced with a Rheinmetall version which featured a new barrel, fume extractor, two-chamber muzzle brake, and a flat wedge breech block. The exterior appearance of the new gun still bore a resemblance to the original M109's short M126 155mm howitzer. The panoramic telescope and sighting scope were replaced with German optics while the M109G's commander was provided with a cupola and vision blocks taken directly from the M113 armored personnel carrier which was in use by the Bundeswehr. Other changes included replacing the 12.7mm M2 heavy machine-gun with the German built 7.62mm Maschinengewehr 3 (MG 3) and fitting German smoke grenade dischargers to the turret front.

     The M109G had a crew of six which consisted of the commander, driver, gunner, two loaders, and two ammunition handlers. The M109G was powered by a 450hp Detroit Diesel 8V71T turbo 8-cylinder, water-cooled engine paired with a 6-speed (4 forward, 2 reverse gears) Allison XTG-411-4A hydro-mechanical manual transmission. This was enough to move the M109G along at a top speed of 35mph with an operational range of 216 miles. The German howitzer had a maximum range of a little over 11 miles and a trained gun crew could sustain a rate of fire of one round every minute. The need for four men to feed the gun was due to the ammunition coming in two separate components; the shell and the bagged powder charge. Because of this, the M109G was only able to carry 28 rounds and thus relied on ammunition carriers to resupply it in the field as the onboard ammunition could be easily expended in a short period of time. Thus, having the extra hands allowed the M109G to be quickly replenished from ammunition carriers.

     As the M109G continued in service, it received one major upgrade in the early 1980s and that was to the M109A3GA1 standard. The gun was replaced with a longer barreled howitzer derived from the towed Feldhaubitze FH155-1 (which gave a maximum range of 15 miles), onboard ammunition capacity was increased to 35 rounds, IFAB (Integrierte Feuerleitmittel Artillerie Batterie) fire control system integration was added, and the installation of the AURORA (Autonome Richt- und Orientierungsaustattung Rohrartillerie; Autonomous Straightening and Orientation Equipment, Tube Artillery) targeting system enhanced the strike capability of the M109A3GA1. By the 1990s, the M109G was being phased out and replaced with the Panzerhaubitze 2000 but it was seen that the PzH 2000 would not be available in enough numbers to quickly replace the M109G and so 262 of the M109A3GA1 were given a further upgrade to the M109A3GEA2 standard. This included expanding the IFAB capability, improving the communication equipment, and incorporating the M109 into the ADLER (Artillerie-, Daten-, Lage- und Einsatz-Rechnerverbund; Artillery, Data, Situation and Deployment Computer Network) system. The ADLER system is a radio assisted artillery command, control, and weapon deployment network. To ease the burden of the loaders and ammunition handlers, a lifting aid and automatic loader was fitted but proved unreliable and so they were often disabled by the crew. The M109 was finally retired from German service in mid-2007.

     The content on the left side of the lower hull is the military symbology for the M109G's unit. The rectangle, called the frame in military terms, represents a unit. The squashed oval with the dot in the center represents a self-propelled howitzer or gun. The line to the right of the oval represents “gun system equipped” while the little line on top of the frame designates a battery. The number 4 is the battery the M109G belongs to while the 145 designates the battalion the battery belongs to. Thus, the unit would the 4. Batterie, Artillerielehrbataillon 145. This unit is no longer in existence with the current artillery units being Artillerielehrbataillon 131, Artillerielehrbataillon 295, Artillerielehrbataillon 325, and Artillerielehrbataillon 345. With the exception of Artillerielehrbataillon 295 (which is under the Franco-German Brigade), the other units are division level assets.

Russo-Ukrainian War: The MP-120 120mm Mortar

Source: USA Today

     Crew of a MP-120 120mm mortar in action somewhere in Ukraine, August 2025. The MP-120 is designed and built by Ukrainian Armor, LLC, a company headquartered in Kyiv, Ukraine. The MP-120, being constructed within Ukraine, allows supply of a heavy mortar to the Ukrainian Army without dependence on external military aid to replace combat losses or bolster units with additional mortars. Another benefit of the MP-120 is the replacement of older Soviet-era 120mm mortars which remain in use such as the 2B11, the 2S12 “Sani” (“Sleigh”), and any remaining 120-PM-38 that have lingered on in service. The MP-120 is also replacing another Ukrainian produced mortar, the M120-15 “Molot” (“Hammer”). The latter, produced by Ukroboronprom Mayak Plant PJSC, entered service in 2016 but has proven unreliable with tube failures having killed and injured over five dozen soldiers by 2021. The MP-120 was accepted for service on January 25, 2022, a little under a month before the Russian invasion.

     The MP-120 has a combat weight of 36 pounds and it takes a trained crew between 2 to 3 minutes to ready the mortar for action. In the background of the photograph, the two-wheeled transport carriage can be seen. This is used to tow the mortar behind a vehicle as well as permit the crew to push the mortar along the ground to the firing position. Once the baseplate is firmly emplaced in the ground, the mortar's barrel bottom is connected to the plate via a ball-and-socket style joint. This permits a full 360 degrees of traverse without having to reposition the entire mortar. The bipod permits elevation and a limited amount of left or right traverse for more fine barrel positioning. The MP-120's barrel utilizes steel construction which prioritizes robustness. This was well illustrated during the MP-120's trials prior to acceptance in which 5,500 rounds were fired through one example. This amount usually resulted in the need for a complete barrel replacement with existing service mortars but the MP-120 showed only .2mm of barrel wear. As a consequence, the MP-120 can effectively fire over 10,000 rounds before the barrel needs replacement.

     Sighting is done using a MUM-706 UMS (Unified Mortar Sight) which has a 2.5x magnification, a 9 degree field of view, 2 inch parallax, 360 degree range of horizontal sighting, between 35 to 90 degree angle of elevation, and plus or minus 30 degrees of angle of inclination in the vertical plane. A benefit of using a UMS is that the sight can be used on other calibers of mortars which include 60mm, 81mm, and 82mm mortars.

     The MP-120 is able to use any 120mm mortar bomb which is designed to be fired through the 2B11 and 2S12. It is also compatible with bombs made for the venerable 120-PM-38 mortar and for the 120-PM-43. Range can vary depending on the bomb. One of the more potent munitions is the 3OF53 HE-FRAG (High-Explosive Fragmentation) bomb. Weighing 35 pounds of which 7.6 pounds is explosive, the 3OF53 can be fired out to a maximum range of 3.5 miles. When it bursts, it creates a lethal fragmentation radius against infantry of 2,690 yards. The MP-120 can fire bombs capable of using surcharges which are supplementary propellant bags (that are horseshoe shaped) which can be added to the bomb's tail. These can extend the range with the MP-120 able to fire such bombs to a maximum range of 4.4 miles. A trained crew can fire up to 15 rounds per minute. The MP-120 also has a safety feature to prevent double loading. This consists of a mechanical interlock that prevents another bomb from being put loaded until the bomb already in the barrel is fired. Also, the MP-120 has a BAD (Blast Attenuation Device) on the muzzle which reduces the blast effects that occur during firing.

Russo-Ukrainian War: The AHS Krab 155mm SPG

Source: Ministry of Defense of Ukraine

     In all, the Ukrainian Army obtained a total of 108 examples of the vehicle shown here, the 48-ton Polish AHS Krab 155mm Self-Propelled Gun (SPG). As part of Poland's military aid to Ukraine, the country provided the first 18 vehicles which were received by the close of 2022. The remainder were obtained via purchase orders with Poland. The ArmatoHaubica Samobieżna (AHS; Self-Propelled Gun-Howitzer) Krab (meaning “Crab“ in Polish) is a joint development by the Polish company Huta Stalowa Wota (HSW), the British firm BAE Systems, and the South Korean entity Samsung Techwin. Work began on the Krab in 1997 and it finally entered production in 2016 with Polish artillery units receiving the Krab soon after.

     Samsung Techwin's contribution to the Krab is the PK9 chassis which is a variant of the chassis used by the South Korean K9 Thunder 155mm Self-Propelled Howitzer (SPH). Power comes from a MTU Friedrichshafen GmbH built MT881 Ka-500 8-cylinder, water-cooled diesel engine that develops 1,000 horsepower. This is paired to a Allison X1100-5A3 transmission with a 6-speed gearbox (4 forward, 2 reverse gears). On roads, the Krab can top out at 37 miles per hour while offroad, in favorable terrain, up to 19 miles per hour can be achieved. Enough onboard diesel fuel is carried to provide for a maximum operational range of 250 miles. The all-welded chassis uses tempered steel armor plating produced by the Australian company Bisalloy with a maximum thickness of 19mm. This provides the approximate equivalent to STANAG 4569 Level 4 protection which means the armor is capable of withstanding up to and including 14.5x114mm API (Armor Piercing Incendiary) ammunition at a minimum distance of 200 meters as well as shrug off 155mm artillery shell fragments as close as 25 meters. Of the five man crew, only the driver sits within the hull.

     The Krab's turret is much the same as that used on the British AS-90 155mm SPH which had been designed by Vickers Shipbuilding & Engineering, a division of BAE Systems. Like the hull, the turret supports the same Bisalloy armor and offers the identical STANAG 4569 Level 4 protection for the four men within. Situated within the turret is a HSW license built 155mm L/52 gun-howitzer. The gun mount provides for up to 70 degrees of elevation and 3.5 degrees of gun depression while the turret can fully traverse 360 degrees. The gun-howitzer uses a sliding block breech and there is a power loader which permits a burst fire rate of 3 rounds in only ten seconds. For three minutes, the Krab can fire 6 rounds for each of those minutes. A sustained fire rate is 2 rounds per minute. All told, the Krab holds 29 projectiles and 28 powder charges in the turret while the hull holds an additional 11 projectiles and 20 charges. The Krab can utilize any NATO compliant 155mm projectile to include the M982 Excalibur extended range, guided projectile. The latter can attain a range of 25 miles. A typical base bleed projectile can reach a maximum range of 19 miles. The gun-howitzer enjoys the benefit of a ZZKO Topaz FCS (Fire Control System) which consists of an automatic aiming system, ballistic computer, laser rangefinder, and both commander and gunner sights interlinked into the FCS. Outside the turret, situated on top of the gun mantlet, is a MVRS-700 SCD ballistic radar to measure the velocity of shells as they leave the barrel. In case of electrical failure, the turret can be manually traversed while the gun can also be manually elevated and depressed as well as loaded by hand. Also, should the Krab find itself in dire straits, it has a gunner's sight to allow it to engage in direct fire. For anti-air and local defense, the Krab can be fitted with a pintle mounted 12.7mm heavy machine-gun on the turret top.

     Other protective systems within the Krab include an automatic fire detection/suppression system while there is a filtered ventilation system that gives a measure of crew protection against biological, chemical, and radioactive substances and agents. The Krab also utilizes the OBRA-3 SSP-1 warning and self-defense system. This consists of external sensors which detect lasers that are “painting” the Krab. Such lasers are often utilized by anti-tank missile systems. The OBRA-3 will warn the crew and designate the direction the laser is coming from. In addition, the OBRA-3 is tied into the Krab's two banks of 81mm dischargers, each bank with four launch tubes. These banks are located on the turret front, one bank on each side of the gun barrel. The OBRA-3 can be set to automatically launch smoke grenades to obscure the Krab and interfere with the laser designator or if desired, the commander can manually trigger the grenades.

     Other systems include a FONET internal communication system for the crew (made by the WB Group), a RRC 9311AP RF digital radio station, FIN 311OL land navigation system, DD-9620 terminal for providing targeting data, GPS system, day/night sights for the commander and driver, and a 5.5 kilowatt output auxiliary generator (for powering the Krab with the engine off).

     The Krab shown here belongs to Operational Strategic Group Dnipro, likely within Tactical Group Kharkiv or Tactical Group Starobilsk which are the group's two subordinate units. The crew has added metal mesh anti-drone screens to the turret, decking, and hull sides. Cutouts have been made in the frontal turret screens to accommodate the 81mm grenade launchers. The Krab looks to have kept its original Polish Army camouflage paint pattern.

     As of September 9, 2025, the visually confirmed Ukrainian AHS Krab losses stand at 41. Of these, 35 have been destroyed beyond repair with the remaining 6 having suffered damage of varying severity.

Russo-Ukrainian War: The BM-27 Uragan 220mm MLRS (BAZ-69092 Chassis)

Source: Reddit

     A mainstay within Russian heavy rocket artillery units is the BM-27 Uragan (“Hurricane”) 220mm MLRS (Multiple Launch Rocket System). Entering service with the Soviet Army in 1975, the Uragan is still in limited production in more modern forms but the vast majority of the BM-27 MLRS in Russian Federation service still utilize the original ZIL-135 8x8 chassis. According to the International Institute for Strategic Studies in 2024, the Russian Army has 218 BM-27 MLRS in service and the ability to call on another 550 of them which remain in storage (assuming they are in a condition enough to warrant returning to service). Nevertheless, the sanctions being applied to Russia since 2022 have had some impact on the ability of Russia to both produce new military hardware and also maintain older vehicles. The ZIL-135 falls into the latter category as production ceased for it in 1994, requiring Russia to source outside of itself. To that end, the photograph of the burned out remains of a Russian Federation BM-27 illustrate Russia's answer to ensuring BM-27 production: using the BAZ-69092 6x6 chassis rather than the ZIL-135. 

     The 13-ton BAZ-69092 isn't new, having appeared in service around 2017, though its history goes back to the 1990s. The key factor is that Bryansk Automobile Plant (BAZ) is able to build the chassis entirely of Russian produced components. Performance mounting the 9P140 220mm rocket launcher complex on the BAZ-69092 (to create the BM-27) isn't known so any performance values are based solely on the BAZ-69092 without any mounted apparatus.

     Power comes from a YaMZ-8491.10-032 turbocharged diesel engine that develops 450 horsepower and this is tied into a YaMZ-2393-10 gearbox. Usage of a mechanical transmission permits all-wheel drive while there is a 2-stage transfer case and locking cross-axle differentials. Top road speed is 50 miles per hour with enough fuel for a maximum operational range (empty of payload) of 621 miles.

     Mounted in front of the engine is the crew cab and normally, this is unarmored. However, the BAZ-69092 can be fitted with an armored cab which does offer some defense against select small arms calibers and shell fragments. Additional crew protection comes in the form of NBC (Nuclear Biological Chemical) systems such as the FVUA-100a-24 filtration system and anti-radiation screens. In the photograph, anti-drone screens have been added to the cab and 16-tube launcher...not that they were effective. The two cylindrical objects just behind the rocket launcher are the engine exhausts. In front of the exhausts is where a spare tire would be kept.

     The capability of the 220mm rockets utilized by the BM-27 offer a range comparable to heavy artillery, if not exceeding guns such as the 2A65 152mm Msta-B. Only the powerful 2A44 203mm gun used on the 2S7 Pion SPG (Self-Propelled Gun) can out-range the BM-27. The launcher is aimed using a PG-1 panoramic telescopic sight and with a full six man crew, the BM-27 can be prepared for firing or broken down for  movement in three minutes. The rockets can be fired one at a time or in salvo with all sixteen rockets capable of being fired in 20 seconds. Assuming the BM-27 is accompanied with a transloader vehicle (which has a crane), reloading the BM-27 fully can take approximately 20 minutes

     The most utilized rocket is the 220mm 9M27F HE-FRAG (High-Explosive Fragmentation) rocket that packs 220 pounds of explosive within a fragmentation casing warhead. Weighing 620 pounds with a length of 15.8 feet, the 9M27F has a maximum range of 21 miles. Another type of rocket is the 9M27K series. These are rockets which disperse submunitions across a target area. The rockets are the 9M27K1 which dispenses thirty 9N210 anti-material bomblets, the 9M27K2 which drops twenty-four PGMDM or PTM-1 anti-tank mines, while the third is the 9M27K3 which disperses three hundred and twelve PFM-1 anti-personnel mines. All three types have a maximum 21 mile range. Two other rocket types include the 9M27S incendiary rocket and the 9M59 rocket which can dispense nine PTM-3 shaped charge anti-tank mines. Like the other rockets, their maximum range is no more than 21 miles.

Russo-Ukrainian War: 155mm M107 Projectile with UZRGM Grenade Fuze

Source: CasualArtyFan on X™

     A casual glance through combat footage from the Russo-Ukrainian War would suggest a good portion of the skirmishes and engagements occur in and around trench lines, within patches of wooded terrain, and in relatively open plains or farm fields. But, at least in the eyes of Russian military leadership, progress is more often than not measured in what village, town, or city has been taken from the Ukrainians and occupied. As such, there is plenty of combat that occurs within the streets and ruins of houses and buildings. The latter is due to the Russian tactic of simply bombarding urban areas with artillery, rockets, drones, and aerial bombs. The U.S. Army used to call combat operations within built-up (urban) areas as MOUT (Military Operations on Urban Terrain) though today, it is usually referred to Urban Operations (UO).

     MOUT missions require specific training and awareness as urban areas present a much different set of problems for attacking troops. For one, a defending force can be fewer in number than the attacking force but the very urban terrain offers advantages to the defenders that make up for any deficit in manpower. Buildings offer concealment and ambush potential, streets running between buildings or houses constrain the movement of vehicles, rubble can provide hiding places for mines or IEDs (Improvised Explosive Devices), taller buildings may offer protection from vehicle armament that may not have the elevation to reach higher positions, basements can hide troops in addition to making it risky for vehicles to crash through houses lest they fall into the basement and become immobile, more built-up urban areas could have underground infrastructure (sewer lines or even subway tunnels) which allow the defender to shift forces unseen, and there is the risk that within the urban combat zone, civilians may remain.

     That said, it is clear that urban combat is a significant challenge to undertake and be successful at it without suffering sizable casualties. Given Russian bombardment tactics, the Ukrainian Army often will not hold a village or town if there is no strategic or tactical reason for doing so. Instead, the Ukrainian Army often makes use of surveillance drones to reconnoiter a captured village or town, looking for Russian positions. If found, FPV drones may be sent in to take out as many of the Russian soldiers as possible. Likewise, if Ukrainian troops conduct a counterattack or raid against Russian positions, aerial drone reconnaissance is key in allowing the Ukrainians to formulate the best avenues of attack to minimize casualties. Sometimes, Russian resistance can be stubborn within a building or residence. If able, Ukrainian troops will attempt to convince the Russians to surrender rather than have to storm into a building or basement. This is surely to lead to injuries or death as there are only so many ways into a building or basement. If the Russians refuse to come out, then Ukrainian troops will utilize grenades and other explosives to finish off the Russian soldier(s) rather than go in and get them. 

     Perhaps the ultimate means to deal with Russians that refuse to surrender is shown here. The shell is a 155mm M107 High-Explosive projectile. The 95 pound M107 is a very old munition, having entered service in 1958. Yet, it remains in production and in use today as a training round as it is relatively inexpensive to produce. This particular M107 has 14.6 pounds of TNT in the main body. Other M107 shells use 15.4 pounds of Composition B (Comp-B) explosive. Such M107 rounds would have COMP “B” stenciled on the shell. This particular shell also has a .3 pound TNT supplementary explosive charge near the nose. This is designated by the stencil that reads “ W / SUPPL CHG”. Instead of the normal fuze (of which there are many with the most common being the M728), there is a UZRGM fuze from a F-1 hand grenade situated in the nose. UZRGM stands for Universal'nyi Zapal, Ruchnaya Granata, Modernizirovannyi (Universal Igniter, Hand Grenade, Modernized) and it, along with the F-1, have been in production since 1939. Ukraine currently produces a variant of the F-1 grenade which entered service in late 2024. The fuze has a delay between 3.2 to 4.2 seconds. The M107 has a lethal radius of 150 meters and out to 250 meters, injury is possible thanks to the approximately 1,950 fragments that are created upon detonation.

     Given the UZRGM's quite short delay coupled with the sizable blast radius of the M107, it makes one wonder exactly how this “grenade” would be employed. A long string perhaps? It would be assumed the UZRGM's fuze would detonate the supplementary charge which in turn would set off the rest of the shell. While the Ukrainian Army does have heavy drones that can (and do) drop 122mm and 155mm artillery shells, they do not utilize grenade fuzes. Also, Ukrainian troops do use hand thrown 120mm mortar bombs for clearing houses and even TM-62 anti-tank mines as satchel charges. Neither are large caliber artillery shells.

     Of course, this could very well be some Ukrainian artillerymen having a bit of fun and making a completely rubbish contraption to get some laughs from the social media world. In fact, when one considers the practicality of this improved explosive, it is a solid 99.9% chance this is a joke which has made a bunch of us discuss it to no end in the halls of Reddit and Facebook.

Kradmelder (Regimentsstab, Artillerie-Regiment 110)

Source: Flickr

     Somewhere on the Eastern Front, a kradmelder (dispatch rider) for the regimental headquarters (Regimentsstab) of Artillerie-Regiment 110 prepares to get under way. Of all the belligerents during World War Two, the German military was the largest user of both motorcycles as well as dispatch riders. These men played a critical role in delivering urgent orders and messages between headquarters and units out in the field. Often, this was because wire communications between units and their headquarters was either not yet in place, the distance too far to establish such communication, time was not available to set up wire lines, or the wire lines run had been broken, sabotaged, or in some way destroyed thus severing such communication channels. Typically, dispatches were sent back and forth by foot when moving messages between züge (platoons) and kompanie (companies) but when communicating to bataillone (battalions) and higher units, the kradmelder was utilized. Obviously, the job of a kradmelder, or any dispatch rider regardless of nation, was a dangerous one as they often operated alone. Even moving behind friendly lines, front depending, was no guarantee of safety. Each kradmelder was trained to maintain his motorcycle and spare parts were often carried so that any common mechanical failure could be corrected in the field.

     The Germans issued the kradmelder, and other users of motorcycles, a unique piece of protective clothing which was called the Schutzmantel für Kraft Radfaher which translates as Protective Coat for Motorcyclists. The double-breasted coat was rubberized so that it was waterproof and it also fit loosely. The coat also featured a wool faced collar, split tail, and four large pockets (two on the front, one on each side) with button-closure flaps. Each tail could be gathered around the rider's leg and buttoned into place. This made for a more snug fit and thus made the coat less awkward to wear when sitting on the motorcycle and also lessened the chances the coat material might catch on objects, to include the motorcycle's own rear tire. The coat was standard for both enlisted men as well as officers who operated motorcycles. The rider in the photograph has wrapped the coats' tails around his legs and the bottom of one of the front pockets can just be seen beneath his arm. The clear shield he is using to protect his face is not often seen in photographs with the usual protective equipment being a pair of goggles and conditions depending, a scarf or piece of cloth to cover the mouth and nose. In cold weather, some kradmelder used their gas masks, without the filter, to protect their face from the frigid temperatures. Other equipment visible includes the cylindrical gasmaskenbüche (gas mask case) and the square, rubberized pouch for the gaskap (gas cape). Strapped to his back is a Mauser 7.92mm k98 bolt-action rifle.

     The motorcycle he is riding is a DKW (DampfKraftWagen) NZ 350. By the time this photograph was taken, DKW was building the NZ 350 exclusively for the Wehrmacht. The motorcycle was powered by a 1-cylinder, 2-stroke, air-cooled 346cc engine which developed approximately 12hp. This was paired with a 4-speed transmission. Top speed of the NZ 350 was 65mph. Fuel capacity came from a 3.6 gallon fuel tank with the engine consuming, under normal operating conditions, almost one gallon of gasoline every 62 miles. Of interest, however, is that the license plate affixed to the top of the front fender is not military but a civilian plate. This is because all Wehrmacht military plates started with WH (Wehrmacht Heer for the Army), WL (Wehrmacht Luftwaffe for the Air Force), WM (Wehrmacht Kriegsmarine for the Navy), or SS for Waffen-SS license plates. The “M” on the plate is the Roman numeral that corresponded to a German city or district in which the motorcycle had been registered. The circular red object is the registration proof of issue by the local police. The upper portion read “Der Polizeiprälident” (Chief of Police) and below it would be the city name. It was not uncommon that civilian owned motorcycles were impressed into German military service given that demand for them was high.

     Finally, when this photograph was taken, the regimental headquarters staff for Artillerie-Regiment 110 had been attached to the I. Armeekorps (1st. Army Corps), 18. Armee (18th. Army) which was a part of Heeresgruppe Nord (Army Group North) during the invasion of Russia that commenced on June 22, 1941 with the launch of Unternehmen Barbarossa or Operation Barbarossa. By October 1941, it was subordinated to L. Armeekorps on several occasions. By the close of 1944, the unit was the 17. Armee and by the spring of 1945, it was under 1. Panzerarmee, LIX. Armeekorps in Silesia. As for the remainder of the unit, I.Abteilung (which encompassed three batteries) was assigned to Artillerie-Regiment 74 in 1939 and III.Abteilung (also three batteries) joined Artillerie-Regiment 74 on July 29, 1940. Artillerie-Regiment 110 was designated a heavy artillery regiment which meant it was equipped with 150mm or 170mm caliber guns.

Remnants of War: Type 96 15cm Howitzers, 4th. Artillery Regiment, 35th. Brigade

Source: A.A. Image

     On August 7, 1942, the 1st. Marine Division, 2nd. Marine Division, the 23rd. Infantry Division (the “American Division”), the 25th. Infantry Division, and other U.S. Forces commenced landings on the island of Guadalcanal. It was the opening salvo by the Allies who were now going on the offensive against the Japanese in the Pacific Theater. The Battle of Guadalcanal, code-named Operation Watchtower, raged for over 6 months, finally ending with an Allied victory on February 9, 1943. The Japanese forces who had been stationed on Guadalcanal since May 1942 were overwhelmed by the initial landings and subsequent battles. The Japanese high command had not expected such an attack and after the shock of it wore off, set about plans to land forces on Guadalcanal and evict the Allied forces from the island. Between August 18, 1942 through November 5, 1942, the Japanese thrust the 2nd. Infantry Division (nicknamed Isamu Heidan, the “Courageous Division”), the remains of the 38th. Infantry Division (nicknamed Numa Heidan, the “Swamp Division”), and elements of the 38th. Brigade onto the island in an effort to defeat Allied forces. In the end, it was all for naught. On February 7, 1943, the Japanese evacuated what forces they could, 10,200 in all, and left Guadalcanal in Allied hands for good. The Japanese lost 19,200 dead of which 8,500 were from combat with the rest dying from malnutrition and disease. The Allies also paid a heavy price with 7,100 dead with another 7,789 wounded.

     Today, the jungles of Guadalcanal remain littered with the debris of war. Some of it is vandalized or stolen by treasure seekers. But, some of the remains of the campaign have been collected together and preserved at the Vilu War Museum. Situated on grounds an hour away and west of the city of Honiara on Guadalcanal, the museum is difficult to find as there is little in the way of signage or promotion to direct visitors to it. Scattered about the property are relics of the conflict, located and brought to the land in the 1950s and 1960s by the current owner's father-in-law. Among the open air displays are these two Type 96 150mm howitzers.

     Development of the Type 96 began in 1920 as a replacement for the Type 4 150mm howitzer that had been in service since 1915. However, the new howitzer was not completed in prototype form until 1934 and even then, changes to the design would not see it put into production until 1937. A total of 440 examples were built and it never did replace the Type 4 which was still in service with the Imperial Japanese Army and would remain so until the end of the war. According to U.S. Intelligence sources (namely from the October 1944 dated manual TM-E 30-480), the Type 96 was considered an excellent gun in design, construction, and effectiveness. The Type 96 was able to fire an 80lb. high-explosive projectile out to a range of 6.2 miles and a good crew could maintain a rate of fire of six to eight rounds per minute. The Type 96 had a maximum elevation of 75 degrees, which was much higher than contemporary howitzers in the same caliber. This elevation, however, could only be achieved if a pit was dug beneath the breech to allow for loading. Without the pit, the maximum elevation was 45 degrees. The Type 96 used the same ammunition as the Type 4 which simplified logistics in regards to supply. The museum's Type 96 examples are devoid of the rubber shod, wooden wheels and the breech locks are missing. This may have been done by the Japanese prior to evacuating the island and thus rendering the guns useless or they may have been removed as a means to demilitarize the guns by Allied forces.

     It is difficult to guess to what unit these guns belonged but it is possible to make an educated guess. The 2nd. Infantry Division included the 2nd. Artillery Regiment. However, the artillery regiments of infantry divisions did not utilize heavy guns like the Type 96. Instead, they were often equipped with 75mm guns, such as the Type 95. The 38th. Infantry Division included the 38th. Mountain Gun Regiment but artillery units such as these, by this time, were equipped with the Type 94 or Type 41 75mm mountain gun. This, then, leaves the 4th. Artillery Regiment which was under the 35th. Brigade. While the 35th. Brigade also had the 10th. Mountain Gun Battalion and the 20th. Mountain Gun Battalion, neither was equipped with the Type 96 and so only the 4th. Artillery Regiment is left. The IJA utilized several non-divisional forces and included in these was the medium artillery regiment. Unlike regular divisional artillery regiments, often, these independent artillery regiments only contained two battalions rather than three. Such medium artillery regiments were equipped with twenty-four Type 96 howitzers. If the guns did indeed belong to the 2nd. Division, this would assume that the 2nd. Artillery Regiment was a mixed field artillery regiment in which one of the three battalions was a medium artillery battalion equipped with seven Type 96 guns. The only other option was that the 2nd. Division was considered a “strengthened division” which meant that the unit's artillery assets would be increased to include a medium artillery battalion but there is no documentation that I found which says when the 2nd. Division deployed to Guadalcanal, it was a strengthened division.

Russo-Ukrainian War: The M240 240mm Heavy Mortar

Source: Reddit

     A soldier of the 3rd. Assault Brigade poses next to one of the unit's handful of colossal M240 240mm heavy mortars. The M240 mortars in use by Ukraine had been in storage until an unknown number were withdrawn, refurbished, and put back into service. Today, the M240 is the largest mortar in operational service in the world. Sometimes classified as a siege mortar, the M240 is designed to bombard fortified positions and the initial design commenced in 1944, being a scaled up version of the PM-43 160mm heavy mortar. Prototypes of the M240 were tested into 1950 and once accepted for service, production started in 1951 with units receiving the M240 commencing in 1953. In total, 329 examples of the M240 were built when production ended in 1958.

     With a combat weight of 4.6 tons and a barrel length alone of 17.6 feet, the M240 requires a maximum crew of 11 to operate effectively. A tow vehicle (usually a MT-LB tracked prime mover or a Ural 373 series 6x6 truck) moves the M240 about as well as carries the crew. Between one to two additional vehicles normally accompany the mortar with one containing ammunition while the other carries equipment and apparatus to assist in emplacing the M240 into a chosen firing position. The maximum tow speed is 25 miles per hour.

     The barrel is of the smooth-bore type and uses a breech-block. The 2-wheel carriage permits a total traverse of 18 degrees and the barrel can be elevated to a minimum of 45 degrees to a maximum of 65 degrees. Both traverse and elevation is manually controlled using gears situated on the left side of the barrel. Sighting is done using older MP-46 or MP-46M panoramic sights or by using a K-1 collimator sight. The carriage is equipped with a recoil assembly, used to reduce firing vibration and be the bridge between the barrel and the mount.

     Loading the M240 is no simple process. As the mortar is a breech loader and cannot be loaded while the barrel is elevated, the barrel is brought down to a horizontal position. The standard 3OF-864 HE (High-Explosive) bomb has a total weight of 290 pounds of which 75 pounds accounts for the explosive in the bomb's warhead. The bomb is brought to the M240 using a 2-wheeled trolley and once near the breech, long-handled tongs are used to pick up the bomb with two men on either side of the projectile providing the lift. A fifth man stands behind the bomb, making sure the bomb's fins are steady and not damaged. Once the bomb is pushed into the barrel, the breech is closed and the M240's barrel returned to battery. A well trained crew can manage a rate of fire of 1 round per minute.

     The M240 is capable of lobbing the 3OF-864 bomb out to a maximum range of 6 miles. A RAP (Rocket Assisted Projectile) version of the 3OF-864 (designated the 3F2 Gagara), fitted with 3M15 rocket motors, can extend that range out to 12 miles. However, even with the RAP bomb, the M240 is within counterbattery range of guns such as the 122mm D-30 howitzer, BM-21 Grad MLRS (Multiple Launch Rocket System), and drones such as the ZALA Lancet loitering munition as well as other FPV drones. Bringing the M240 into action takes up to 25 minutes from the halt and with apparatus to assist with the set up. The M240 can only fire from firm ground and if the ground is too hard, explosive charges are used to blow a pit into the ground for the base plate to settle into. While preparing to fire may go unnoticed, after the first bomb is fired, detection may only be a matter of time. It takes up to 15 minutes to return the M240 to traveling condition and this makes “shoot and scoot” tactics of very limited value. This issue is the main reason the Soviet Union developed the 2S4 Tyulpan (“Tulip”) which is a tracked, self-propelled mounting of the 240mm 2B8 mortar (a modified M240) that entered service starting in 1975.

     Other than the common 3OF-864 ammunition, it is believed the Ukrainians also have some stockpiles of the 3F2 Gagara bombs and a more limited availability of the 1K113 Smelchak (“Daredevil”) semi-active, laser-guided mortar bomb. The latter is composed of a 3F5 240mm HE projectile, a optoelectronic correction head, four adjustable fins, and six solid-fuel rocket motors. In order to effectively utilize the 3F5 bomb, it requires soldiers on the ground equipped with either a 1D15 or 1D20 laser rangefinder/designator. The 1D15 has a maximum range of 3 miles while the 1D20 has a 4 mile maximum range. The 1K113 itself has a maximum range of 5.7 miles.

     Doctrine in using the 1K113 as designed involves aiming the M240 towards the designated target and firing a standard round. The observation team, already in place (and usually no more than 5 miles from the target), reports the impact and calls back adjustments to the firing unit. After the gunner makes the corrections, the 1K113 is then loaded and fired. The soldier manning the 1D15 or 1D20 unit aims the designator at the target where it receives a radio signal from the M240 firing position regarding the bomb's trajectory. As the bomb nears the target, the designator switches to targeting mode, “painting” the target with laser pulses which the bomb's correction head picks up via reflection. Around .5 of a mile from impact, the rocket motors are utilized to make any corrections to the flight path to ensure successful impact. The usual deviation from the aim point is no more than 1.8 meters.

     As of July 28, 2025, the Russians have lost a total of sixty-one 2S4 Tyulpan (10% of the total production run) while the Ukrainians have not lost any of their M240 towed mortars.

M102 105mm Howitzer: Battle for Quảng Trị

Source: The Associated Press

     On March 30, 1972, the Chiến dịch Xuân Hè 1972 (1972 Spring - Summer Offensive), better known as the Easter Offensive, was launched by the People's Army of Vietnam (PAVN) supported by Việt Cộng forces. In the attack, the PAVN took the city of Quảng Trị as well as Quảng Trị Province along with a portion of Thừa Thiên Province. The Army of the Republic of Vietnam (ARVN), while initially thrown back, dug in along the My Chanh River north of Huế and halted the PAVN advance with the assistance of U.S. air support. On June 14, 1972, I Corps commander Lieutenant-General Ngô Quang Trưởng commenced planning to retake Quảng Trị Province with a combined U.S. and ARVN mission called Operation Lam Son 72.

     On June 27, 1972, the U.S. 9th. Marine Amphibious Brigade launched a feint assault along the Cua Việt River but on the ground, RVN Marine and RVN Airborne forces met stiff resistance from PAVN troops as they moved northwest of the Thạch Hãn River. To assist, on June 28, U.S. Marine Medium Helicopter Squadron 164 (HMM-164; the “Death Riders”) and HMM-165 (the “White Knights”) airlifted the 1st. and 4th. RVN Marine Battalions behind PAVN positions. After further fighting, both the Marine and Airborne forces reached the outskirts of Quảng Trị on July 7. The defenders within the city were not the cream of the PAVN crop and instead, were relatively untrained replacement soldiers and militiamen. This was because the PAVN 304th. Division and 308th. Division had pulled their more experienced fighters out of Quảng Trị to protect them from U.S. air power. Despite this, PAVN forces in the city had artillery support, terrain advantage, and had well prepared positions to the point that ARVN attacks against the city met with stiff resistance. On July 11, U.S. Air Force Boeing B-52 bombers bombarded the city and in an effort to cut off the PAVN supply line, HMM-164 and HMM-165 were again called in to drop the RVN 1st. Marine Division north of the city. It was costly as three helicopters were downed with another 25 receiving various amounts of damage from viscous anti-aircraft fire. After three days of brutal combat against the PAVN 48th. Regiment of the 320th. Division (the Đồng Bằng Division or Delta Division), the regiment was forced to retreat. By July 20, the Marines had consolidated their positions while the RVN Airborne forces continued to penetrate into Quảng Trị. Two days later, the 5th. Marine Battalion was airlifted by HMM-164 to interdict PAVN supply lines near the Cua Việt River and combined with two additional Marine battalions, including tanks, managed to defeat PAVN forces in the area after two days of fighting. By July 27, it was the RVN Marines assaulting the city after relieving the diminished RVN Airborne troops and for weeks, combat raged in bitter house-to-house fighting. On September 9, 1972, the 147th. Marine Brigade and the 258th. Marine Brigade pushed on the heavily defended city center which finally fell on September 15. The brutal combat cost ARVN forces 3,658 dead with 20 U.S. servicemen killed while it is estimated PAVN losses were at least 10,000 killed. In support of the RVN troops, the U.S. Air Force and U.S. Navy (flying from five aircraft carriers) flew 5,461 close air support sorties while the U.S. Air Force launched 2,054 B-52 bomber sorties.

     The Associated Press photograph shown here was taken on July 10, 1972 and shows a RVN Airborne artilleryman manning a U.S. built M102 105mm howitzer. The location was a firebase situated near La Vang which was 3 miles south of Quảng Trị. The M102 was a lightweight (1.5 tons) howitzer whose design commenced in 1962 with the first examples entering service in 1966 to replace the World War Two era M101A1 howitzers. The gun used a box trail that had a platform beneath the gun that when in place and the wheels raised, allowed the gun to be traversed a full 360 degrees. Gun depression was a maximum of 5 degrees with a maximum elevation of 75 degrees. Recoil was via a hydro-pneumatic system and the gun used a vertical sliding-wedge breech. The standard high-explosive shell weighed 33lbs. and with the maximum powder charge, the range was 7.1 miles. With a rocket-assisted shell, the range was increased to 9.4 miles. Today, the M102 is no longer used by the U.S. Army, having been replaced by the M119 though it still exists in some U.S. National Guard inventories. It is also still used by the U.S. Marine Corps but usually only for ceremonial duties. The U.S. Air Force continues to use the M102 in the Lockheed AC-130J Ghostrider gunship. Outside of the U.S., a handful of operators still use the M102 with the largest user being Jordan that maintains 50 guns on inventory.

28cm Haubitze L/12: Vintage Siege Howitzer


     On June 2, 1942, the Germans launched Operation Störfang (Sturgeon Catch) to take the Russian held port city of Sevastopol once and for all. Rather than launch conventional attacks as before which got them nowhere, the Germans instead elected for siege warfare, intending to pound the defenders into submission using heavy artillery before sending in ground forces. To do this, the 306. Artilleriekommando der Armee (Army Artillery Command) assembled the biggest siege guns and heavy artillery that could be had under the 11. Armee. All together, nine artillery battalions and three heavy and railroad artillery batteries came together, including elements from Artillerie-Bataillon 672 which fielded the massive 80cm Schwerer Gustav railway gun, Schweres Mörser-Bataillon 833 which operated two of the huge 60cm Karl-Gerät self-propelled siege mortars, and Schwere Artillerie-Batterie 459 that operated the sole remaining Krupp built 42cm Gamma-Gerät siege gun. Also in that number was Artillerie-Bataillon 744 and this unit and the guns it was equipped with is the subject of the photograph.

     Obscured by gun smoke and dust kicked up after firing is one of two 28cm Haubitze L/12 ( H L/12) heavy siege howitzers operated by Artillerie-Bataillon 744 during Operation Störfang. The gun was originally designed as a coastal howitzer (Küstenhaubitze) that was to be placed near critical coastal infrastructure and it was designed to fire projectiles at a high-angle so as to come down onto the thinner armor of a warship's decking rather than the much thicker belt armor (meaning, the sides). As a coastal defense gun, it was mounted on a turntable set into concrete and to protect the gun and crew, it had a 60mm thick armored dome fitted to it. The entire assembly was called the Mittelpivotlafette C/92 (Center Pivot Mount C/92). The H L/12 entered service in 1892 with a four gun battery being deployed in Tsingtao, China to defend the German colony there while another battery protected the ports of Wilhelmshaven and Blankenberge in Belgium. The only other user of the howitzer was Portugal who bought several of the guns in 1902 to protect the port of Lisbon. While the exact number of howitzers built by Krupp isn't known, some survived World War One and remained in the hands of the Reichswehr and ultimately it is believed nineteen examples were still on inventory at the start of World War Two. Long by this time, the howitzer had passed into obsolescence when the ranges of main guns mounted on warships exceeded that of the howitzer. Still, the artillery forces of the Wehrmacht lacked heavy siege guns and so a small number were pulled from static defensive locations in order to deploy them in the field. To do this required significant manpower, effort, and time.

     To transport the H L/12 required four loads: the barrel, the cradle, the gun mounting, and the components of the wooden ground platform. Once a suitable firing position was selected, a pit was dug and once that was completed, the wooden platform was assembled within the pit. After the platform was completed, the gun mount was fitted and secured down on the platform then the gun cradle and finally the barrel itself was installed. All together, to set up a single howitzer took between three to four days. The length of the H L/12 was 11.1 feet and the combat weight was 49.5 tons. The gun mounting provided a full 360 degree rotation thanks to a turntable situated on the bottom of the mounting. The maximum elevation of the gun was 65 degrees but the mounting provided no gun depression. The H L/12 used a horizontal sliding block breech and was percussion fired. Recoil absorption was by way of two hydraulic-pneumatic recuperator cylinders with additional absorption coming from the inclined plane of the gun mounting. The howitzer only fired one type of ammunition, the 28cm Sprenggranate L/3.5 high-explosive shell that weighed 772 pounds. To effect the maximum range of 6.5 miles, a seven-part powder charge that weighed 38 pounds was used. The H L/12 was not overly accurate and the effective range was a bit less at 6.2 miles. Against ships, the shell was able to penetrate 100mm of desk armor at a 63 degree angle. To facilitate loading, a crane was fitted to the gun mount and a trained crew could fire one round every one to four minutes. While the lack of accuracy of the H L/12 was an issue against mobile warships, against stationary targets like a city, the howitzer was more than effective in delivering its share of devastation.

     All told, the artillery amassed under 11. Armee dropped 46,750 tons of ordnance on Sevastopol and when the Germans took the city on July 4, 1942, only eleven buildings still stood without damage following both the artillery bombardment and the aerial bombing campaign. Although a German victory, the Germans suffered 27, 412 casualties and the Romanians 8,454 casualties in comparison to 118,000 Soviet casualties.

     The H L/12 howitzers would appear again in combat, this time during the Warsaw Uprising which commenced on August 1, 1944. There, the howitzers contributed to the purposeful destruction of Warsaw during the combat (which ended on October 2, 1944) and afterwards. By January 1945, some 85% of Warsaw was destroyed. The scale of the destruction was immense with 10,455 buildings, 923 historical buildings, 25 churches, 12 libraries, 81 primary schools, 64 high schools, and 2 universities being razed to the ground.
