Russo-Ukrainian War: The FN MAG General-Purpose Machine Gun

Source: @inukraine.official on Instagram

     Somewhere above Ukrainian held territory, a Mil Mi-8 (NATO reporting name Hip) helicopter of the Ukrainian Army Aviation branch prepares to engage a Russian Geran-2 loitering munition. The Mi-8 has two door gun positions. The first is seen here, situated on the left side of the fuselage, behind the cockpit. A second position is in the rear of the fuselage, firing out from a opening in the right hand clamshell cargo door. Normally, the 7.62mm PK machine-gun would have been the standard defensive weapon but here, the gunner has elected to use a 7.62x51mm FN MAG machine-gun. Countries that have sent FN MAG machine-guns to Ukraine include Belgium, Canada, France, Luxembourg, and the Netherlands. The gunner's FN MAG looks to have been one provided to Ukraine by France. The FN MAG, the original developed and built by the Belgian arms manufacturer FN Herstal, entered service in 1958 and today, it is deployed by dozens of countries. Several countries license build the FN MAG and they are the United Kingdom (as the L7A1), Canada (as the C6), Indonesia (as the SM2), Sweden (as the Kulspruta 58), and the United States (as the M240).

     The FN MAG is, as mentioned, chambered for the 7.62x51mm NATO cartridge, and it uses a gas operated, long-stroke bolt action which fires from an open bolt. The rate of fire varies from 650 rounds per minute up to 1,000 rounds per minute. This variance is created by the gunner adjusting the gas valve which permits him to accommodate various cartridge loadings, to overcome barrel fouling, and modify the rate of fire to suit the target being engaged. The empty weight of the FN MAG is 26 pounds though this particular FN MAG uses a polymer plastic buttstock that lightens the mass to a small degree. The FN MAG feeds from the left, ammunition being held in either the M13 disintegrating link belt or the non-disintegrating DM1 belt. Each belt holds 50 rounds and belts can be connected to create longer ones. A quick-change barrel allows for rapid switching in case of barrel failure or to allow a barrel to cool after prolonged sustained fire. When firing from a bipod, the effective range of the FN MAG is .5 of a mile (800 meters) but if using a tripod, the effective range increases to 1.1 miles. The maximum range of the round is 2.1 miles.

     The regular sights of the FN MAG consists of a front blade sight and a rear mounted folding leaf sight with both an aperture and a notch. As this example of the FN MAG is fitted with a Picatinny rail, the gunner has added what looks to be a Thermion 2 thermal imager rifle scope made by the Lithuanian based company Pulsar. The Thermion 2 series is offered in two objective lens sizes: F35 and F50. The Thermion 2 uses a AMOLED (Active-Matrix Organic Light-Emitting Diode) display with a magnification ranging between 2.5X up to 12X depending on the model. Other features of the Thermion 2 scope series include Wi-Fi for connecting to smartphones (the thermal imager can be operated from a compatible smartphone), reticle style customization, color options for the reticle and display, photograph and video recording (16 GB of internal memory storage), and IPX7 (Level 7) waterproofing. This means the scope can be fully submerged in water up to a depth of 3.2 feet for no longer than 30 minutes without permanent damage. Detection range is between .8 of a mile up to 1.1 miles for the larger model. The FN MAG has a brass catcher bag fitted to collect ejected empty cartridges so that they do not roll around the floor of the compartment, causing a slip hazard for the crew. 

     As it turned out, the gunner was able to successfully engage the Geran-2, shooting it down where the drone crashed into a copse of trees before exploding when its warhead detonated.

Russo-Ukrainian War: The DShK M1938 "Dushka"

     A soldier of a territorial defense brigade posing for the camera with his “Dushka”, the venerable DShK M1938 12.7mm heavy machine-gun. First introduced in 1938, the DShK (standing for Degtyarov-Shpagin Krupnokaliberny; Degtyarov-Shpagin Large-Caliber) remains in service with dozens of military forces around the world and it has seen combat starting in World War Two and in just about every military conflict since then, to include the Russo-Ukrainian War. This particular make is the DShKM, evidenced by the muzzle brake, which appeared in 1946. When production ended in 1980, over 1 million DShK machine-guns had been built and to date, it has yet to be fully replaced in Russian Federation service despite newer weapons such as the NSV and Kord machine-guns. In addition to ground mounts, the DShK is also used on armored vehicles and tanks as a anti-aircraft machine-gun.

     The DShKM seen here is utilized by a rapid reaction anti-drone unit, hence being mounted in the bed of a pick-up truck. The locally fabricated pedestal mount permits traverse and elevation and it even has minimal gun shield. Usually, the DShK uses a 60-round metal ammunition can and this constitutes a single belt (which is usually 50 rounds). However, when engaging drones such as the Shahed-136, volume of fire is a factor in scoring a successful hit. As such, a single belt can be expended very quickly and in some cases, the drone(s) can leave the kill zone quickly, meaning the DShK is out of action while a new belt is fed into the weapon. Here, the fabricator of the gun mount adapted a 20 liter (5 gallon) metal fuel canister to act as an extended ammunition can. From appearances, it can hold up to five ammunition belts for a ready ammunition count of 250 rounds.

     Empty, the “Dushka” weighs 74 pounds and it uses a gas-operated flap-locking action. The 5.4 foot long DShK has a cyclic rate of fire of 600 rounds per minute but a practical rate of fire is between 100 to 200 rounds per minute. The most often used round is the B-32 steel-cored API (Armor-Piercing Incendiary) bullet which, despite being introduced in 1936, remains in production. The B-32 can penetrate 20mm of rolled homogeneous armor at 500 meters. As such, the DShK is a threat to lightly armored vehicles. A similar round is the BZT-44 APIT (Armor-Piercing Incendiary Tracer) and this is often mixed into ammunition belts of B-32 rounds. Another round used is the MDZ incendiary bullet and this might also be mixed with API ammunition. The maximum effective range is 1.2 miles with a maximum range of 1.6 miles.

Russo-Ukrainian War: The M2A2 .50 Caliber HMG

     A gunner of the 23rd. Mechanized Brigade on the practice range, operating a Browning M2A2 .50 caliber (12.7mm) heavy machine-gun. The M2A2 is secured onto a locally fabricated anti-aircraft pedestal mount which permits a good bit of elevation to allow the gunner to track and aim at Russian drones. The pedestal mount itself is bolted down onto the bed of a pick-up truck and from appearances, it is capable of being lowered down into the bed when not in use, permitting the tarp (seen rolled up) to cover the bed and protect the mount, M2A2, and ammunition from the elements. The M2A2 seen here is able to utilize scopes and other optics as evidenced by the rail mount on the top rear of the receiver, just forward of the trigger. To the left of the M2A2 is the ammunition can, held via a cradle secured to the mount. Based on the muzzle, the weapon is likely a U.S. Ordnance manufactured M2A2.

     The roof of the pick-up truck's crew cab has no less than five drone jammers of three different makes. It is now more the norm for Ukrainian as well as Russian vehicles to have more than one jammer. The intent is generate interference across multiple frequencies in the hope that any drone that seeks to attack the pick-up happens to be using one of the jammed channels.

Russo-Ukrainian War: The M2E2 "Ma Deuce" .50 Caliber HMG

Source: Reddit

     A mainstay weapon of Ukrainian rapid response anti-drone units is the Browning M2 .50 caliber (12.7mm) heavy machine-gun. Here, it looks to be mounted in the bed of a 5th. generation Toyota Hilux double-cab pick-up truck. Nicknamed the “Ma Deuce”, the development of the M2 commenced in 1918 and first entered U.S. military service in 1933. Besides being used by infantry as a heavy support weapon, the M2 and its derivatives were used in aircraft (both as main armament and defensive armament), mounted on naval ships, mounted on tanks (typically for anti-aircraft use), and more. The M2 is still in production and has seen action in dozens of conflicts around the world in the hands of over two scores of military forces. The version of the weapon shown here is a M2E2 which incorporates a quick change barrel.

     By itself, the M2 has a weight of 84 pounds of which the barrel accounts for 24 of those pounds. It uses a short recoil-operated action and has a cyclic rate of fire of between 450 to 550 rounds per minute. However, the M2 is a select-fire weapon, being able to fire one round at a time as well as full automatic. The gunner, with training, can conduct slow fire which consists of 5 to 7 round bursts every 10 to 15 seconds (a rate of fire of under 40 rounds per minute) or rapid fire which is 5 to 7 rounds every 5 to 10 seconds (a rate of fire over 40 rounds per minute). The gunner must bear in mind that firing more than 150 rounds in two minutes will heat the barrel to the point that a round can cook off in the breech. The gunner has 10 seconds to extract a unspent round from the breech before a cook off can occur. If the round cannot be extracted, then the gunner has to wait at least 5 minutes before attempting extraction and give time for the barrel to cool. The M2 is belt fed and ammunition is held together by either M2 or M9 links.

     Typical ammunition is the M2 ball, M1 tracer, M2 AP (Armor-Piercing), and M8 API (Armor-Piercing Incendiary) cartridges. The M2 ball round can penetrate up to 1 inch of concrete at 1,500 meters and 6 inches of sand at the same distance. The M2 AP round can penetrate 8mm of homogeneous armor at 1,500 meters (just under 1 mile), 5mm of face-hardened armor at 1,500 meters, and 406mm of sand at the same distance. The maximum range is 7,400 meters or 4.6 miles. The M2E2 seen here is using the standard leaf-type rear sight and the front blade-type sight. The rear sight is graduated from 100 to 2,600 yards and has a windage knob for deflection adjustments.

     The gunner is wearing a Partizan Camouflage uniform which is also known as SS Leto/Autumn (“leto” means summer in Russian). The camouflage is made by the Russian company Kula and it is derived from the Russian military camouflage pattern of the same name which first appeared in 2004. For anyone familiar with German World War II camouflage, Partizan is based on the Waffen-SS camouflage pattern known as SS-Eichenlaubmuster (“oakleaf pattern”). Like Waffen-SS camouflage, Partizan is reversible into the “autumn” side which replaces the green base color with a brown hue. Kula makes another similar pattern, SS Spring (also called Medusa or Partizan-M), which uses the same pattern but uses a dark brown background with various shades of green splotches. The latter also more closely matches the coloration of the Waffen-SS “oakleaf” camouflage.

Russo-Ukrainian War: The PKM GPMG

     A machine-gunner of the 108th. Mechanized Battalion “Da Vinci Wolves”, 59th. Motorized Brigade “Yakiv Handziuk”. He is armed with a PKM general purpose machine gun (GPMG), one of the most common machine-guns in use by the Ukrainian military as well as the armed forces of the Russian Federation. Entering service in 1961 as the PK (Pulemyot Kalashnikova; Kalashnikov's machine-gun), the modernized PKM (Модернизированный; Modernized) appearing in 1969. The PKM and its variants remain in production and equip dozens of military forces around the world.

     The PKM is chambered for the Soviet 7.62x54mmR cartridge and the machine-gun uses a gas-operated, long-stroke piston, open/rotating bolt action. The open bolt assists in cooling the breech to prevent ammunition cook-off due to heat generated by automatic fire. The bolt and bolt carrier are upside down and the gas piston and the gas system are mounted beneath the barrel. The cyclic rate of fire of the PKM is 600 to 800 rounds per minute though the practical rate of fire is far less, being 250 rounds per minute. With the cartridge generating a muzzle velocity of 2,707 feet per second, the effective range of the PKM is 1,000 meters though its maximum range is 3,800 meters. Ammunition usually comes in 100-, 200-, or 250-round belts using non-disintegrating metal links with the belts kept in ammunition boxes. The 100-round belt box is considered the “assault” box as it can be attached to the bottom of the PKM. The larger belts are typically utilized when the PKM is being fired from a tripod, the tripod having mounts for the boxes. The rounds feed from the right and the spent brass ejects to the left. In practice, after firing 400 rounds in succession, the barrel is either changed out and replaced with another to give the removed barrel time to cool or the gunner ceases fire to permit the barrel to cool in place. Failure to do this risks bore wear.

     The PKM weighs a tad shy of 20 pounds which includes the detachable bipod but does not include the assault ammunition box. If a full assault box is attached, the weight increases by 8 or 7 pounds depending on if the box is the standard one or the lighter, aluminum version. Normally, aiming is done using iron sights but the PKM can be fitted with aiming optics using a side-rail bracket on the left side of the receiver. The more common optical sight used is the 1P29, a 4x magnification optic. The rear iron sight is a sliding tangent type with 100 meter increments starting at 100 meters up to 1,500 meters. The rear sight also has small side dials to adjust for windage.

Russo-Ukrainian War: Ukrainian Triple-Mount RPK-74

Source: Global Images Ukraine.

     One of the main components of Russia's aerial raids against Ukrainian infrastructure (power plants, factories, electrical distribution centers, etc.) and civilian targets is the Geran-2, the Russian version of the Iranian HESA Shahed 136 loitering munition. The Geran-2 is relatively cheap at a single unit cost of no more than $80,000 for the current model. As such, they can be launched enmasse (and  usually in combination with other weapons, such as cruise missiles) in order to overwhelm Ukrainian defenses and ensure successful strikes. A component of Ukrainian air defense comprises rapid response anti-drone units which, upon receiving the flight paths for Russian drones, deploy in or near the flight paths to engage them with an array of light, medium, and heavy machine-guns mounted on trucks. Given the 115 miles per hour top speed of a Geran-2, utilizing machine-guns to shoot down the drones is a viable (and cost effective) method. In some cases, static anti-drone defenses are set up around valuable targets or as a secondary layer of defense against any drones which get through the mobile anti-drone units as illustrated here. One of the techniques to increase the chances of a successful hit against drones is to simply throw as many bullets as possible into the path of the drone and hope one or more of the rounds strike the drone to such a degree as to down it. And so this anti-drone mount holds three RPK-74 light machine-guns.

     Introduced into Soviet Army service in 1974, the RPK-74 is chambered for the Soviet 5.45x39mm round and all three of the RPK-74 weapons are secured to a metal frame which permits a high degree of elevation (very useful for anti-air duties) which in turn is fitted to a heavy tripod. To the right of the central RPK-74 is a shoulder stock which the gunner can use to stabilize the mount, assist in absorbing recoil, and guide the mount when traversing and elevating. Below the shoulder stock is a trigger which permits the gunner to fire all three RPK-74s at the same time. Between the center and outer right RPK-74 is a ring sight and given the electrical cord, it is possible that a night sight or a spotlight is connected to the gun mount to aid the gunner in acquiring his target. The basket, though empty, is likely for keeping additional magazines to speed reloading. Speaking of magazines, the RPK-74 can utilize either a 30- or 45-round box magazine.

     Using a gas operated, rotating closed bolt action, the RPK-74 is capable of firing up to 600 rounds per minute. Assuming the 45-round magazine, a single RPK-74 can empty the magazine in 3.5 seconds. So, with three RPK-74 weapons firing in unison, this means the gunner can send 135 rounds towards the target in those same 3.5 seconds. With a muzzle velocity of 3,149 feet per second, the 5.45x39mm round has an effective range of .6 of a mile (1,000 meters) if using saturation fire. The bullet itself can travel as far as 2 miles but accuracy is about nil at such a distance. Given the short effective range, this particular anti-drone weapon arrangement relies on the Geran-2 to be flying at low altitude (it can fly as low as 197 feet) and close to the gun emplacement for a realistic chance of the gunner being successful in his engagement. Otherwise, it really does become a “fill the sky with lead” in the direction of the drone and hope to get a very lucky hit. Fortunately, some Geran-2 do fly at low altitudes to make detection more difficult and to lower the window of time the defenders have to engage before the drones move out of range or lines of sight get blocked by terrain and terrain features.
