Russo-Ukrainian War: Ukrainian Special Forces in Irpin

     To some analysts, Kyiv should have fallen by now. With the well publicized “40 mile” convoy of Russian vehicles, some pointed to this being the build-up to finally taking down Kyiv. Except it hasn't happened. The city is under bombardment from Russian rockets, namely from M-21OF 122mm rockets fired from BM-21 “Grad” launchers. Rocket type depending, the M-21OF has a maximum range of between 8 miles to as much as 25 miles. But so far, the Russians have been unable to penetrate into Kyiv proper.

     The convoy has stalled and is now being subjected to Ukrainian attacks at the hands of small Ukrainian units and drone strikes. To the Ukrainian military, hitting supply lines only exacerbates an existing problem of Russian combat units being low on fuel and troops low on food. Russian tanks and vehicles cannot run if they have no petrol. This leads to the relatively common sight of abandoned trucks and vehicles that fall into the hands of Ukrainian forces.

     The photograph here shows a man by the first name of Volodymyr (in the soft cap), a Special Forces team leader, with two of his men. The team is operating in the Kyiv suburb of Irpin', some 14 miles from the city center of Kyiv. Bucha, another suburb just to the north of Irpin', has also been the scene of combat between the Russians and Ukrainians. Special Forces are playing a significant role in repelling numerous attempts by the Russians to push into both suburbs. These units operate at night, some even using tactical drones of their own with thermal optics to pinpoint Russian targets. Poor weather has seen the Russian Air Force limit sorties though Ukrainian troops are equipped with U.S. built FIM-92 Stinger surface-to-air missiles supplied by Lithuania, Latvia, the Netherlands, and Germany. Such weapons have already claimed some Russian aircraft. For anti-tank work, the units are using British supplied NLAWs (Next Generation Light Anti-tank Weapon).

     Fitted into Volodymyr's tactical vest are three 40mm HE-SD (High-Explosive Self-Destruct) grenades (next to a "BIC" lighter) for the under-barrel GP-25 or GP-30 grenade launcher. The SD feature is important when fighting within urban environments. After launch, the fuze will arm and within 14 to 19 seconds, the grenade will detonate. Thus, if the grenade doesn't explode upon impact, the grenade will still detonate and thus not pose a hazard to Ukrainian troops or civilians which would not be the case with the standard 40mm grenade that would remain active if it failed to detonate. The gloved soldier has his hands on what could be a silencer or suppressor for his AK-74 assault rifle. It could be a PBS-1 silencer which was more of a sound suppressor, only reducing the discharge by 15 decibels (dB) from 150 dB. Also, as the phrase “An army marches on its stomach”, spoken by Frederick the Great and Napoleon, still holds true today, the soldier in the background has a plastic spoon tucked into his gear, ready for use when the next meal comes around.

     All three men are using caution tape for identification and possibly could belong to the 72nd. Information Warfare and Psychological Operations Center (based in Brovary, a suburb of Kyiv) or from the Special Operations Forces Command which is based in Kyiv proper.

Russo-Ukrainian War: Abandoned 2K22 Tunguska

     One of the more curious aspects of the war is the lack of Russian air power in the skies. In a November 2021 report from Flight International, the Ukrainian Air Force fielded 37 Mikoyan MiG-29 Fulcrum multi-role fighters, 12 Sukhoi Su-24 Fencer attack jets, 17 Su-25 Frogfoot attack/close air support jets, and 32 Su-27 Flanker multi-role fighters. Against these 98 combat aircraft (Ukraine has no bombers any longer), the Russians have arrayed at least 300 combat aircraft in the region. Yet, even now, Ukrainian pilots are still able to sortie against Russian ground targets and engage in low-level aerial combat with what Russian aviation is about in the sky.

     So why is this the case? There are many opinions out there. The first is a lack of PGMs (Precision Guided Munitions) coupled with the inability to accurately deliver said ordnance. The latter is due to inadequate pilot training. It is believed that Russia's inventory of PGMs is very low and thus if any strikes were to be carried out, it would be done with unguided bombs and rockets. By having to use such munitions, it forces the aircraft into range of Ukrainian surface-to-air missiles, especially man-portable ones.

     Another factor is the fear that Russian ground forces will shoot first and ask questions later. Considering that a decent portion of Russian troops are conscripts, this fear is very much valid. Combine this with the fact the Ukrainian Air Force flies the same exact types of aircraft the Russian Air Force does, the risk is very real and the last thing the Russian Air Force wants is lost planes due to friendly fire.

     Finally, some think that the typical Russian pilot lacks flight hours, and thus the needed skill to engage in actual combat successfully, in comparison to Western pilots. On average, a Russian pilot gets under 100 hours in the cockpit every year while, for example, U.S. Air Force pilots can get up to 240 hours each year.

     The photograph here shows an abandoned 2K22 Tunguska somewhere around Kharkiv. The 2K22 is the replacement for the ZSU-23-4 Shilka, a rather lethal self-propelled anti-aircraft gun (SPAAG) that entered service in 1960. So lethal was the Shilka that many NATO nations stated in their infantry combat doctrine that any time a ZSU-23-4 was spotted in a column being ambushed, it was to be destroyed immediately before any other target as the quadruple 23mm cannons would quickly put an end to the attack. Although the Russian Marines still deploy the Shilka, the Russian Army uses the 2K22.

     The 2K22 is built on a GM tracked chassis, powered by a V-46-6-MS turbocharged, V-12, fuel-injected, water-cooled diesel engine developing between 780 to 840 horsepower. This gives a top road speed of 40 miles per hour and enough fuel for a 310 mile operational range. The SPAAG is equipped with the Hot Shot (NATO code-name) system that combines a parabolic E-band target acquisition radar (what we see in the folded position in the photograph) with a J-band monopulse tracking radar fitted in the center of the turret front. The target acquisition radar has a 360 degree field of view, can detect aerial targets out to 11 miles and flying as low as 50 feet off the ground. It can track targets starting within 10 miles at an altitude of 2 miles or less. Engagement can occur when the target speed is 1,640 feet per second or less with the response time of the weapon systems being 6-8 seconds. The Hot Shot system is all-weather, day and night.

     Speaking of weapons, the 2K22 is fitted with two 2A38M 30mm guns with each gun provided with 1,904 rounds of ammunition. Underneath each gun is a battery of four 9M311 surface-to-air missiles (NATO code-name SA-19 Grison), for a total of eight ready-to-fire missiles. The combined fire of both cannons is 3,900 to 5,000 rounds per minute but the usual is brief bursts of 83 to 250 rounds target depending. The maximum effective range is 2,000 meters while with the 9M311, the maximum range is between 5 miles to 6.2 miles. The missiles cannot be fired while the 2K22 is on the move though the guns can when set to full automatic computer controlled engagement. If need be, the gunner is provided with a stabilized sight for manual engagement, using the radar for range data.

     The 2K22's armor protects the four man crew from small arms fire and shell fragments but it is incapable of surviving hits by anything heavier. It is well equipped with good ventilation, heating system, NBC (Nuclear Biological Chemical) system, automatic fire suppression, night vision, extensive communication equipment, and navigational systems.

     The Ukrainian Army had, in a 2012 report, 70 Tunguska on strength but built on a 2S6 chassis rather than a GM chassis. How many remain in service now is unknown. It is believed that this example may have ultimately been destroyed by Ukrainian forces. This assumes the Russians rendered the 2K22 unusable prior to abandoning it.

Russo-Ukrainian War: Abandoned Russian D-30 in Kherson Oblast

     It should be noted that Ukraine is not being invaded by one country, Russia, but also Belarus and Chechnya. The latter is a de facto independent state but is within the Russian republic while Belarus is an independent country. Both of these countries have supplied troops to the invasion and in the case of Belarus, allowed Russian troop movements through their territory.

     The city of Kherson, located in south Ukraine, is being reported as surrendering to Russian forces as of March 2. The city's mayor, Igor Kolykhaev, stated that Russian soldiers are within the city and that there are no Ukrainian military forces within the city limits. However, other reports state there are still skirmishes occurring outside the city proper. If Kherson is, indeed, under Russian occupation, it gives the Russians a vital port on the Black Sea and secures a base of operations to launch attacks against Odessa. The Kherson Oblast (region) continues to see combat with several battles having been fought and still ongoing within the area. Cities lost to Russian forces include Melitopol and Berdiansk while the cities of Mykolaiv and Zaporozhzhia are still being contested.

     The photograph here shows a part of a Russian column destroyed somewhere within the Kherson Oblast. The gun being towed is a D-30 122mm howitzer. This is a weapon nearly 60 years old, having entered service in 1963. Although no longer built in Russia, the Russian military still has some 4,750 D-30 howitzers in service. It is still built in other countries and over 60 nations (including Ukraine with a reported 129 examples) have the D-30 in their military arsenals. This is a testament to its design and robustness. When deployed in action, the D-30 unfurls three stabilizers with the gun in the center, fitted atop a turntable that allows 360 degree rotation. The hydro-pneumatic recoil system sits on top of the gun barrel which allows for a low profile of the D-30. The gun has a maximum elevation of 70 degrees and a maximum depression of 7 degrees. The D-30 uses a semi-automatic, vertical sliding-wedge breech. The howitzer has a crew of seven and a trained team can run 10 to 12 rounds through the gun per minute though in practice, it is usually half that rate of fire. In part, this is because the muzzle brake is so large (in order to absorb half the recoil forces) that is creates a massive over-pressure around the gun. This means the crew typically uses a long lanyard to fire the gun and stands well away from it, reducing load times. The low profile also means the D-30 can be used for direct fire and comes with a telescope sight for anti-tank duties. The typical range of the D-30 using standard high-explosive rounds is 9.6 miles but with rocket-assisted shells, it can attain a range of 13.6 miles.

     The truck the howitzer is being towed by appears to be either a ZiL-131 or a Ural 4320. The white “Z” on the rear gate has been the subject of a number of online articles. Some state the “Z” means the unit is part of the thrust into Ukraine from the east. A “Z” with a white square around it indicates forces coming up from Crimea (from the south) into Ukraine while a “O” means units from the north that pushed into Ukraine from Belarus. Chechen units are believed to use a white “X”, special forces a white “A”, and Russian Marines a white “V”. Some other sources state these may simply be general identification marks to avoid friendly fire incidents without any specific allocation to where units are going within Ukraine.
