40MM Grenade Mortar

Since April, a Ukrainian unit has shared a number of short videos showing a small mortar capable of firing 40mm grenades.

From their patches and TikTok username, 16batzsu, the men’s unit appears to be the 16th Separate Rifle Battalion. They appear to be part of the battalion’s embedded mortar battery and are seen operating other larger mortars and automatic grenade launchers in numerous videos.

*A close up of the small mortar (via 16batzsu)*

On the 11 February, 16batzsu shared a video showing a small mortar with a stainless steel insert seen dropped into a small hand-held mortar. The same video was shared on their YouTube account under the title ‘New Toy’. While the resolution of the video is low it clearly uses the same barrel sleeve principal seen in later videos. In replies to comments 16batzsu explain that the small mortar has a range of 2km and is 30mm in calibre. This suggests that the weapon may launch 30×29mm VOG grenades normally fired by AGS automatic grenade launchers. Unlike the later 40mm mortars it does not appear to have a bipod. No further videos featuring the 30mm mortar have been shared.

*A still from a video showing a 30mm handheld mortar (via 16batzsu)*

The first video providing a close up look at the 40mm mortar was shared on the 26 April, with the small mortar in a pit next to an 82mm mortar. The mortar uses 40mm high velocity grenades which are slid into the base of a rifled steel barrel sleeve. The rifling is needed to both maximise the grenade’s range but also impart spin which arms grenade. The loaded sleeve is then dropped into the mortar tube, the grenade’s primer presumably strikes the mortar’ firing pin and the grenade is ignited firing it out of the mortar. The sleeve remains in the tube.

*A closeup of the inside of the barrel sleeve, note the rifling (via 16batzsu)*

In terms of size the small mortar looks similar to the Ukrainian 60mm KBA-118, however, the base plate, bipod and tube differ. Despite similarities I haven’t been able to find an exact match to a mass-produced mortar. The weapon appears to be well made and the examples seen in the videos appear to be near identical suggesting they may be a locally developed and produced weapon.

In a pair of videos posted on 3 May, we get a closer look at the weapon and a member of the unit explains the principal behind how it works. The tube has a pair of parallel cuts which allow the steel barrel sleeve to be removed. The video shows a pair of the small mortars and also shows the rifling inside the sleeve. The sleeve appears to have approximately 16 rifling grooves and on its exterior are three rings cut into the top end of the sleeves outer surface to aid removing it from the mortar tube.

*A 40mm high velocity round about to be loaded into a rifled barrel sleeve (via 16batzsu)*

Finally, in a video posted on 9 May, we can clearly see the mortar fired a number of times. The operators can also be seen loading the 40mm grenades into the rifled barrel sleeves. One man loads the three tubes while another fires the mortar. The spent grenade cases are removed with the aid of a metal ramrod. The 40mm grenades which appear in the video are high velocity high-explosive dual-purpose (HEDP) grenades of the type used with Mk19 automatic grenade launchers. The reason the sleeve is rifling is to arm the grenade’s fuze when the round is fired. These include grenades like the US M383, M384, M430 and M677 as well as German DM111 and DM 112.

*A still of a 40mm grenade being loaded into a barrel sleeve (via 16batzsu)*

So what is the small mortar for? Why not just use the unit’s Mk19 automatic grenade launcher? My initial theory was that the barrel sleeve might provide an increase in range over the Mk19 though the 2,000 metre range mentioned in one of the videos suggests the mortar has a range on parr with the Mk19. Another theory is that the unit’s Mk19 may be inoperable and they still have a supply of 40mm grenades to use. The grenades are also perhaps more readily available and cost-effective than small mortar rounds. It could also potentially have the effect of mimicking drone-dropped 40mm munitions, keeping enemy combatants on the look out for drones. As a harassment weapon the small mortar seems to have potential, allowing its operator to fire from cover while being relatively lightweight allowing it to shift firing positions quickly. The accuracy of the weapon is difficult to gauge but with the aid of an observation drone rounds could be walked into the vicinity of a target. The mortar is a very interesting piece of innovative engineering.

What Weapons Did Wagner Capture in the Soledar Mines?

At the beginning of May 2023, Russian media shared a flurry of videos from salt mines near Soledar. The videos showcased a captured weapons storage depot said to be inside part of the mine complex which was recently captured by Russian private military contractor unit Wagner. Most interesting was the lack of modern weaponry displayed, indicating Ukraine may have removed the more useful equipment stored there. The mine is located in the vicinity of the settlements of Paraskoviivka and Soledar, north of Bakhmut.

*A Lend-Lease M1A1 Thompson removed from its shipping crate (via social media)*

The mines contain a former Soviet arms storage facility, initially said to have been established in the late 1950s, which was taken over by Ukraine when the USSR collapsed. There is also a small arms and light weapons repair facility established by the Ukrainian Army. The facility was temporarily seized by Separatists forces in April 2014, with one Separatist militia member then telling Sky News that: “There are rifles, machine guns, heavy weapons and millions and millions of rounds of ammunition. We are here to stop the forces of the west and anyone else for that matter from getting their hands on them.” Later fighting saw the region secured by Ukrainian forces and the mine back under Ukrainian control.

With the heavy fighting in the region and Bakhmut becoming a focus of Russia’s offensive efforts in the second half of 2022 and the first half of 2023, the mines have again become a focal point. Russia reported that the area the mines were located was captured in mid-February but it wasn’t until early May that the weapons depot was secured and featured in a flurry of videos.

*A crate of damaged AK-74s at the captured Ukrainian repair facility (via A. Simonov)*

Using the videos shared by Russian media outlets and individuals lets take a look at what has reportedly been captured. From the imagery it is immediately clear that the depot appears to have been stripped of the most useful and modern materiel which was stored there. Videos from the mine focus on the scale of the depot and the plethora of vintage weapons which are said to be stored there.

The first video posted by Alexander Simonov, an RIA contributor, on his personal page on 30 April, begins with the reporter descending in an elevator explaining that the depot is 150 metres below ground. He describes the scale of the facility as ‘impressive’ spanning 5km with 28 galleries and a repair facility. He also explains that Ukraine’s retreating armed forces removed the most modern equipment and unsuccessfully attempted to mine the depot’s entrance. Simonov says that the depot primarily holding small arms ammunition. Simonov speaks to an individual who shows him parts of the depot and explains how it was set up in the 1960. The individual describes the galleries as almost 400 metres long – with torches failing to illuminate the whole gallery. Simonov is told theres 292,000 boxes containing small arms.

*Prigozhin opens a crate of three PM1910 Maxims (Wagner)*

Simonov is then shown a repair facility where badly damaged weapons have been abandoned by the Ukrainians when they retreated from the depot. The weapons appear to have been sent to the depot where their damage would be assessed to see if it was possible to repair them. The weapons seen include: AK-74 and AKS-74s, two damaged Barrett M107A1 rifle, DP-27s and SPG-9 recoilless guns.

In one shot there are hundreds of stocks for SKS carbines [misidentified in the video as Mosin-Nagant stocks] seen and in a clip from Simonov’s RIA report shelves filled with AK-74 furniture are seen. In another clip posted a on 1 May, Simonov also examines a DShK heavy machine gun which the Ukrainians have adapted with a muzzlebrake, bipod and stock. Next to it is a PK general purpose machine gun.

*One of the weapons depot’s 28 galleries with thousands of boxes stacked (via A. Simonov)*

The RIA report published on 30 April, appears to have been filmed at the same time and shows boxes of AK magazines, manuals and walls hung with Soviet-era small arms disassembly posters as well as the shelves of AK furniture seen in the first video. Another shot shows an AK-74 still in a vice and a disassembled a AGS grenade machine gun in a crate.

An Izvestia report published on 2 May shows more of the weapons stored in the depot with the footage showing a crate of Second World War Lend-Lease M1 Thompson submachine guns. Also seen are DPM light machine guns and damaged weapons including an RPG-7 and AK-74s. The video also shows the 4.5 tons of explosive stacked to blow the entrance to the galleries.

*Prigozhin lifts the original packing paper to show an M1928A1 Thompson (Wagner)*

Also published on the 2 May was the first video showing Yevgeny Prigozhin, owner of the Wagner group, visiting the mine. In the video Prigozhin shows off some more Lend-Lease Thompsons submachine guns, this time M1928A1s, “new in oil packing’ he says. He also mentions that there are thousands of PPSh and PPS submachine guns and Maxims, showing a crate containing three PM1910 Maxim guns. In the video he says: “Do we really need this? Should we leave it here to rot further? I wrote to everyone I could. No one is interested.” Suggesting that he would exchange them for shells to support Wagner operations. Despite Prigozhin mentioning PPSh and PPS submachine guns we’ve been unable to find any imagery of the weapons in the mines.

Since 2 May, there has been no further imagery from the mines. It remains to be seen if any of the weapons stored in the mine are utilised by Russia and what exactly is held there with some sources suggesting tens of thousands of weapons dating from the first and second World Wars and later. With many of the weapons obsolescent the most useful of those shown in the videos will likely be the old Soviet machine guns (the DPs and Maxims) and the small arms ammunition. The old Soviet submachine guns and Thompsons will be of less practical value. It’s telling that the officially released videos showed little modern equipment.

Evidence of Ukraine’s First Use of Storm Shadow Cruise Missiles

Last week, on 11 May, the UK became the first country to provide Ukraine with medium range cruise missiles. Less than a week later the first evidence of their use has emerged.

Storm Shadow is an air-launched subsonic cruise missile with a reported range of 250-300km (155-185 miles). It can reportedly reach speeds of Mach 0.8 or around 620 miles per hour. This will enable Ukraine to strike targets within territory occupied by Russia including Crimea. Theoretically, Storm Shadow could also strike targets inside Russia, but the UK has provided them on the understanding they will not be used outside Ukraine’s borders.

Storm Shadow is characterised by its accuracy and also has a sophisticated warhead: the Bomb, Royal Ordnance, Augmenting CHarge (BROACH). The 450 kg (990 lb) BROACH warhead uses a precursor penetrator charge followed by a follow-through main charge to penetrate hardened shelters and structures.

*RAF technicians arm a Typhoon with Storm Shadow, 2021 (Cpl Steve Buckley/UK MOD Crown copyright)*

Storm Shadow is said to be extremely accurate. Once the missile is released from the aircraft its wings deploy and it uses a GPS/INS and Terrain Profile Matching navigation system to guide the missile to the target area. The missile typically flies at a low level and on its the final approach it jettisons its nose cone and the on-board infrared sensor guides the missile to the impact point. With a reported price tag of around £790,000 per missile, they are typically used against high value targets.

Development of the missile requirement began in the mid-1980s becoming part of the multi-nation NATO Modular Stand-Off Weapon (MSOW) programme. While the US pulled out of the programme in the late 1980s Matra BAe Dynamics continued development of a missile based on the Matra Apache. The missile became known as Storm Shadow and was procured by the UK in 1997, it entered service in 2002.

The missile also entered service with the French in 1998 as SCALP-EG (Sistème de Croisière Autonome à Longue Portée – Emploi Général, or Long Range Autonomous Cruise Missile System – General Purpose). Since then Storm Shadow and SCALP have been used in the Gulf, Iraq, and in Libya by the UK’s Royal Air Force and the French Air Force.

Ben Wallace, UK Defense Secretary, addressed the UK’s Parliament on 11 May saying:

“Today I can confirm that the UK is donating Storm Shadow missiles to Ukraine… the use of Storm Shadow will allow Ukraine to push back Russian forces based within Ukrainian sovereign territory. …Russia must recognise their actions alone have led to such systems being provided to Ukraine. It is my judgement as Defence Secretary that this is a calibrated, proportionate response to Russia’s escalations.”

Wallace added that it hadn’t been easy to incorporate the missile on a former Soviet aircraft. He said “that has been one of the reasons for the time… working out if it is technically feasible, and I would like to pay tribute to our scientists & technicians.” It is believed that Ukraine’s Su-24 Fencers have been adapted to launch the missiles.

Storm Shadow is key for Ukraine as it provides a much needed long range, deep strike capability, well beyond that of HIMARS rockets and other artillery. Ahead of Ukraine’s anticipated offensive the cruise missiles will allow Ukraine to strike high value targets including infrastructure and logistics nodes and command and control centres – most of which have been repositioned outside of HIMARS/GMLRS munitions range.

*A building in Luhansk claimed to have been struck by a Storm Shadow missile (via* social media)

13 May saw the first evidence of Ukraine’s use of the missiles emerge with Russian media outlets and telegram channels sharing fragments collected in Luhansk. Russian media shared photographs of an industrial building destroyed. Subsequent photos and videos showing further fragments with serial numbers and other markings were also shown. Russian state media reports that LPR Separatist authorities claim Luhansk has been targeted with at least three Storm Shadow missiles. This claim is yet to be independently verified.

*A tail fin fragment believed to be from the Storm Shadow strike on Luhansk (via social media)*

The strike on the target in Luhansk is the first with physical evidence of Storm Shadow’s use, now that the missile is known to be in service it will inevitably be one of the weapons discussed when considering future strikes but given the missile’s cost and the relatively small number available, the Ukrainians will likely be picking their targets carefully.

On 16 May, France signalled its intention to also provide Ukraine with longer range missiles, while not confirmed by name this potentially means its SCALP-EG missiles. In late May some German politicians made calls for Germany’s similar Taurus missile to be provided to Ukraine.

Update – 24/5/23: During a visit to Ukraine UK secretary of Defence signed a photograph of a Ukrainian SU-24MR carrying a Storm Shadow. Inscribing: “To all the brave ‘few’ who risk all for the glory of Ukraine” in reference to Churchill’s remarks referring to the RAF as the ‘few’ during the Second World War.

Update – 3/6/23: A photo of a Ukrainian air force SU-24M was shared online showing it carrying a pair of what appear to be Storm Shadow missiles.

Mk153 SMAW In Ukraine

Recent imagery confirms the presence of the Mk153 SMAW in Ukraine. In the last couple of months there have been sightings of the Mk153 in use at the front and at a Ukrainian Armed Forces training ground. The Mk153 is a shoulder-fired rocket launcher capable of engaging structures and armoured vehicles.

The Mk153’s cousin munition – the one-shot, disposable M141 SMAW-D has been seen in theatre in fairly small numbers since February 2022. We have an earlier article/video looking at the SMAW-D, check that out if you haven’t already.

The Mk153 is primarily used by the USMC and was developed from the Israeli IMI B-300 and introduced in the mid-1980s. So what actually is a Mk153? The USMC describes the SMAW as:

“a one-man operable, 83 mm smooth bore, shoulder-fired, rocket launcher with a spotting rifle attached to the right side of the launcher tube. The encased rocket is fitted into the aft end of the launcher, and the fiberglass encasement is discarded after use. The spotting rifle, which improves firstround hit probability, is fed 9 mm tracers by a magazine, which holds six rounds. The 9 mm round is ballistically matched to the 83mm rocket.”

The SMAW (or Shoulder-Launched Multi-Purpose Assault Weapon-Disposable) can fire Encased High-Explosive, Dual Mode (HEDM) and Encased High-Explosive, Anti-Armor (HEAA) rockets. The HEDM is an anti-structure and anti-light armour munition with a warhead containing 2.4 pounds Aluminized Comp A-3 capable of penetrating 200mm (8 in) of concrete. The HEDM has a maximum effective range of 250m. The HEAA is a dedicated anti-armour round able to penetrate up to 600mm (23.6in) of rolled homogeneous steel, with a maximum effective range of 500m. It uses a shaped charge warhead with 1.89 lbs Octol explosive. The Novel Explosive (SMAW-NE) has a 4lbs enhanced-blast warhead, containing PBXN-113, designed for bunker busting which the USMC manual describes as “designed to provide enhanced-blast lethality to defeat personnel in reinforced structures and caves.”

The Mk153 has iron sights and a Mk42 3.8× magnified optic and a 9mm spotting rifle on the side of the launch unit. This spotting rifle fires tracer rounds which match the rocket’s ballistics and can help range the target and aid the operator in applying the right hold for the target. The tracer cartridge that contains a 9mm jacketed bullet with an aft burning .22 calibre tracer element. Spotting rifle magazines for the rockets are supplied on the outside of the rocket carry tube end cap.

The first sighting of a Mk153 in the field came from some B roll footage of a UK Channel 4 News report published on 28 February. It showed men of the Ukrainian 68th Jager Brigade on the front-line near Vuhledar. Several soldiers are seen preparing a Mk153 to fire.

On 17 March a video featuring a Mk153 SMAW being fired at a range was shared on Telegram. It shows a SMAW being fired and a pile of spent tubes and unfired rockets on the ground. The fired and unfired rockets all appear to have yellow bands indicating high explosive munitions – the Mk153’s practice round has a brown band. Sadly, we can’t make out the other markings which would indicate the type of rounds being fired.

At the end of March another video of Ukrainian soldiers preparing a Mk153 for firing was shared again at the range. The video gives us the best close up of the launcher in theatre so far and shows not one but two launch units. We get a good look at the tube and the launch unit’s spotting gun on the right hand side. This video shows the weapon being prepared to fire, the rocket is inserted into the launcher and rotated clockwise a quarter-turn to lock it in place before the Ukrainian soldier fires at a target down range.

Another interesting detail we can see is the white paper hang ing from the rocket. This is a humidity indicator which allows quick visual inspection to see if the rocket might have been compromised by moisture. The indicator on this rocket appears to have pink in all three of its indicators circles, meaning the munition might be compromised, in USMC service this would mean the rocket needs to be returned to the ammunition supply point. Despite this the rocket appears to fire normally and detonate down range. It’s worth noting that the launch unit isn’t fitted with an optic in any of the clips.

Update – 24/05/23: An additional clip of a SMAW being fired in an urban environment, perhaps during the defence of Bakhmut, date unknown.

A very rare sighting of a Mk153 SMAW in action in Ukraine. Telegram source simply captioned it Bakhmut, date unknown.

RARGOG Polymer Belts

Back in July we looked at polymer belt links developed for PK series machine guns made by a Ukrainian company, the Kharkiv Plant of Personal Protective Equipment – who trade under the name RAROG. Development of the links began back in 2015, and since the Russian invasion in February production of the links has increased.

Unlike the classic metal 7.62×54mmR belts, the new polymer belts are disintegrating – meaning once the round held in the belt link is fired and the next round is loaded it falls out of the gun just as with NATO standard disintegrating belts. This has the advantage of there are no longer being a long empty section of belt trailing from the gun.

*A PK with RAROG’s polymer belt links at the range (RAROG)*

One question that was regularly asked in the comments of the first video was – can the links not be made from a biodegradable material?

Speaking RAROG they made it clear that there is currently no possibility of using biodegradable materials to make the belt links as they would not be strong enough for them to work properly. Unsurprisingly, the reality of the situation means a reliable, durable product that won’t fail, with dire consequences, during a firefight is a much more important consideration.

*Polymer belt links and fabric belt box (RAROG)*

The company relocated from Kharkiv to Lviv following the invasion but quickly re-established manufacturing and tell me that on average 100,000 links are shipping per month, although they have the capacity to produce far more. They are often shipping with their fabric belt bags. The bags and links are largely privately purchased by Ukrainian combatants.

Vintage Weapons In a Modern War: The TT-33 Pistol In Ukraine

The fighting in Ukraine has seen a wide range of small arms in use ranging from the cutting edge to the antique. We’ve seen a number of older weapons like Mosin-Nagant rifles, M1910 Maxim machine guns and DP light machine guns in service with both sides. [We’ll take a look at those in future videso] The TT-33 pistol, a pistol which first entered service 90 years ago, is another older weapon which is again seeing action. The examples seen in theatre are likely a mix of privately owned firearms and pistols drawn from Ukrainian stores.

Introduced in the mid-1930s to replace the 1895 Nagant revolver, over a million TTs have been produced. Designed by Fedor Tokarev the pistol became the Soviet Union’s primary side arm, seeing service during the Second World War alongside the Nagant.

The TT-33 is a semi-automatic pistol, chambered in 7.62×25mm. It feeds from an 8 round single stack magazine and uses John Browning’s short recoil tilting-barrel action. The TT is an extremely robust pistol and remained in service well into the 1950s with the Red Army and continues in service around the world even today.

*A photo of a TT-33 shared by the TDF’s 127th Kharkiv Brigade (via social media)*

Pistol use in general in the current conflict doesn’t appear to be prolific but a considerable number of combatants are frequently seen carrying side arms. Everything from Makarovs and Stetchkins to more modern Glocks and Ukrainian Fort handguns. Pistols are often carried by soldiers working in roles which frequently see them separated from their service rifle and by those who prefer to carry a secondary weapon.

While we’ve seen TT-33s in the hands of Russian and Ukrainian separatist troops in this video we’ll largely focus on Ukrainian use. At the fall of the Soviet Union a considerable amount of surplus small arms fell under Ukraine’s control, including substantial numbers of TT pistols. While not general issue it has been in service with the Ukrainian Army, National Guard and the Border Guard Service. This video definitely isn’t an exhaustive survey of TT use in Ukraine but lets take a look at some examples:

At the start of April 2022 the training department of the command headquarters of the Ukrainian Territorial Defense Forces have published a number of high quality videos showing how to disassemble and clean the TT.

The Ukrainian YouTube channel, Boys from the Forest (ХЛОПЦІ З ЛІСУ) shared a video looking at the TT in May 2022. They concluded their video by shooting a block of explosive reactive armour with the pistol – to no effect. In June Alina Mykhailova, a medic with 1st separate mechanised battalion “Da Vinci Wolves” shared a photo of some firearms used by the unit, including amongst other things – a TT pistol.

*A photo of a TT-33 shared by an International Legion volunteer (via social media)*

In around August some members of a TDF unit posed with a Nestor Makhno banner and a DP light machine gun and a TT-33 pistol. A Russian news report from around Soledar, published on 5 August, featured an interview with a soldier carrying a TT in a front pouch of his load bearing equipment. On the 12 August a Ukrainian operator shared a couple of photos of his side arm, a 1945-dated, Izhevsk manufactured TT-33 with wooden grips. Date and location they were taken wasn’t shared.

In an interesting video posted around the 25 August, a TT-33 is used to test some captured Russian steel plate. Yurii Kochevenko, an officer of the 95th Air Assault Brigade, shoots a one of the plates point black with TT he carries in a webbing holster. The 7.62x25mm round doesn’t cleanly penetrate the plate but appears to impart enough force to crack the metal.

At the end of November the Military Institute at the National University in Kyiv shared photos of cadets taking part in a shooting championship using TT pistols.

On 30 December, the 247th Separate Battalion of the TDF’s 127th Kharkiv Brigade shared a photo of Vitaly, a member of the battalion, armed with an AK-74 and on his plate carrier he has a TT in a Cytac holster. These tactical holsters for the 90 year old pistol retail for around 780 Hryvnia. On the same day Ukrainian personnel shared an update video from their position in Bakhmut, one of them is carrying a TT on his plate carrier.

A TDF officer, call sign Witch, has been seen numerous times carrying a TT-33 as her sidearm. Videos posted to her TikTok on 24 December and 12 January show it in a holster on her plate carrier, with a coil lanyard fitted. A video shared by the TDF Public Relations Service on 19 February also gives us a good look at the TT carried by Witch.

*Ukrainian marksman position with a rotary grenade launcher, a UAR-10 and a TT pistol (via social media)*

On 26 February 2023, the TDF’s 127th Kharkiv Brigade shared a gallery of photographs featuring the TT on their instagram page. The caption notes that: “Despite the fact that this pistol was actively used even during the Second World War, it is simple in design, reliable in operation, small in size, comfortable to carry and always ready to defeat the Russian invaders.”

A Ukrainian special operations unit shared a photo of a member of the unit sat beside a Russian prisoner while holding two TT-33 pistols, one in its original finish and the other was a camouflage paint job. Most recently at the start of March a Ukrainian marksman active around Bakhmut shared a photo of his position with a rotary grenade launcher, a UAR-10 and a TT pistol.

Ukrainians Training with Bulgarian Arsenal AKs

At the end of January a series of photographs taken by Canadian Army photographers showed Ukrainian troops being trained at sites in the UK as part of Operation Unifier. Unifier is a training mission carried out by the Canadian Armed Forces with training currently taking place in the UK alongside the multi-national training mission Operation Interflex.

What is interesting about the new imagery is that the Ukrainian troops in training are all armed with Bulgarian-made Arsenal AK-pattern rifles. This is the firs time this particular AK has been seen in use. If you saw our earlier videos looking at the other types of AK-pattern rifles procured by the UK for their training of Ukrainian personnel you’ll have seen Zastava M70s, Chinese Type 56s and East German MPi KMS-72s are in use.

The rifles were almost certainly procured by the UK Ministry of Defence and like the other AK-pattern rifles being used for training they will probably remain in the UK to be used in the training of future Ukrainian personnel.

The Arsenal AKs were seen for the first time in photographs taken on the 23 January, during a lesson on field craft. The Ukrainian troops can be seen taking notes with the rifles slung at their sides.

The rifles appeared in photographs again on 25 January, when Canadian medics were instructing Ukrainian recruits on the application of tourniquets. One of the rifles was seen slung over the shoulder of a Ukrainian soldier rendering aid.

Subsequently on 26 January, soldiers from the 3rd Battalion, Princess Patricia’s Canadian Light Infantry were photographed instructing Ukrainian recruits during a weapons class. The class saw Ukrainian troops learning how to operate NLAWs, grounded on the floor next to them are their Arsenal AKs.

A series of images from a counter-explosive training session on searching and spotting mines and booby traps showed a platoon of Ukrainian trainees equipped with the Bulgarian AKs.

Ukrainian recruits under the supervision of Canadian soldiers from 1 Combat Engineer Regiment practice searching for and identifying booby traps, during Operation UNIFIER on 28 January 2023 in the United Kingdom. (Corporal Eric Greico/Canadian Armed Forces)

The rifles seen in all of the photographs appear to be basic model rifles, none of the weapons have railed handguards or Picatinny on the receiver cover for mounting optics. This suggests that they are either AR-M9Fs or AR-M14Fs (at least according to Arsenal’s website). The ‘F’ refers to the folding tube metal stock which helps identify the rifles as Arsenal-made AKs. The characteristic flash hider and furniture also identify them as Arsenal rifles. It is difficult to identify what calibre the rifles are chambered in as the Ukrainians are never seen with magazines loaded into their weapons (as they’re unnecessary for the training being carried out).

The AR-M9 and M14 are bother available chambered in 5.56x45mm and 7.62x39mm. Logical arguments could be made for either calibre: the UK MoD has confirmed that other AK-pattern rifles that have been procured are chambered in 7.62x39mm so this chambering would give them ammunition commonality with other AK-pattern rifles in use. Alternatively, the UK has ample stocks of 5.56x45mm and this would also more closely mimic the 5.45x39mm AK-74 rifles the Ukrainians are likely to be issued when they return home. Either way they are AK-pattern rifles which enable training on manual of arms, handling and firing with similar weapons the trainees will probably be equipped with.

The rifles have black polymer furniture and appear to be either new or in excellent condition with few visible scratches or scrapes to the finish or furniture. Notably each rifle has green tape around the base of the folding stock onto which a rack number has been written in black marker pen.

Addendum:

As is sometimes the case with writing these articles and videos while in the process of research and production new source material emerges. On 1 February, the UK MoD shared a series of new photographs from the training of Ukrainian troops. In these a number of the Arsenal AKs were seen fitted with blank firing adapters (BFAs). This is interesting for a number of reasons – previously we have seen Ukrainian trainees using British L85A2s with BFAs for the elements of their training which required blank fire. We have covered this in an earlier article/videos – it requires additional, and largely unnecessary training on the use of the British bullpup.

BFAs for the 7.62x39mm AK pattern rifles procured earlier by the UK appear to have been deemed either unsafe for use in British training areas or BFAs and blank 7.62x39mm ammunition haven’t been readily available. The new photographs show that BFAs are in use with these Bulgarian AKs – likely because they were procured with the rifles direct from the manufacturer.

These UK MoD photographs also show the rifles with magazines – which indicate the rifles are chambered in 5.56x45mm. As I theorised earlier the UK has ample stocks of both blank and ball 5.56x45mm which would simplify the logistics of training the nearly 20,000 Ukrainian soldiers expected to be trained in the UK in 2023.

The Australian Army has also shared a large number of photographs from their involvement in the training of Ukrainian troops in the UK. The Australian military have dubbed their effort Operation Kudu. They describe Kudu as: “A contingent of up to 70 Australian Defence Force (ADF) personnel are deployed on Operation KUDU to assist with the UK-led and based training program.” The Australian photographs show the training and familiarisation of Ukrainian troops with the Arsenal AKs with both Australian and British instructors seen in the photographs.

Update 08/02/23:

The Canadian Ministry of National Defense has released a short video showing some of the training Canadian personnel in the UK are delivering to Ukrainian troops as part of Operation Unifier (the Canadian element of the international Operation Interflex.)

The video focuses on some of the field exercises and urban training being provided and heavily features Bulgarian Arsenal AR-M9F (5.56x45mm) AK-pattern rifles.

M16A4s in Ukraine

On 12 January, a unit of the Ukrainian Army’s 47th Separate Mechanised Brigade (47 OMBr) was seen equipped with US M16A4s for the first time. The rifles were seen equipped with Trijicon ACOG optics and some, a considerable percentage, were seen with M203 40mm under-barrel grenade launchers, and of course rail covers.

Previously, we have seen a considerable number of M4A1 carbines, some equipped with M320 40mm grenade launchers. This, however, is the first time we’ve seen the M16A4. Other elements of the 47 OMBr have been seen equipped with FN FNCs in 5.56x45mm. The 47 OMBr appears to be a unit which has largely been allotted western small arms and equipment. The brigade was formed in November 2022 and, as with a number of other new Ukrainian brigades, has been built up from a battalion (which was raised in August 2022) to a regiment to a brigade level formation.

*A close up of an M16A4 with an ACOG and M203 UBGL and rail covers in Ukrainian service (47 OMBr)*

The M16A4 is a 5.56x45mm, select-fire rifle which uses a direct impingement gas system and a rotating bolt locking mechanism. The M16A4 was developed in the late 1990s and entered service in January 1999. It and has seen service with the US Army, USMC and US Navy. The US Army began to move away from the M16A4 in favour of the M4A1 in 2011 while the USMC favoured the rifle’s 20 inch (50.8cm) barrel length and began replacing its M16A2 with A4s in 2002, only in October 2015 did they begin to transition to the M4A1 Carbine and latterly the M27 for infantry Marines. Despite this the M16A4, however, remains in widespread service use.

The photographs and short video where the rifles were seen for the first time were posted to commemorate a visit from members of Plast, Ukraine’s scouts organisation, who brought a lamp of the Fire of Peace to be lit with members of the brigade.

Another photograph was shared on the brigade’s social media on 22 January, showing a close up of an M203-equipped M16A4, which was also mounted with an ACOG. How many of these rifles have been transferred is unknown, the most recent US Department of Defense fact sheet on aid to Ukraine, published on 25 January, lists 13,000 assorted small arms.

*An as-issued M16A4 service rifle with quad rail forend, railed receiver, ACOG and grip pod (US Army)*

The rifles appear to be straight from US Army or USMC inventory and look to be in good shape. The rifles have been predominantly made by Colt and FN. None of the imagery has been close enough yet to see which manufacturer the now-Ukrainian rifles were made by.

I expect we will be seeing a proliferation of the M16A4 rifles just as we have the M4A1 carbines since the early summer of 2022. The 47 OMBr probably won’t be the only unit to field them and we’ll probably be seeing many more of these in the future as the US military has considerable stocks of the rifles and production lines are still active. If and when we do, I’ll follow up with further videos/articles.

Update 20/03/23: Sergeant with Ukraine’s 47th Brigade seen armed with M16A4 equipped with M203 grenade launcher and an ACOG.

Ukrainian Troops Train with G36s

We’ve previously looked at Ukrainian troops training with the British L85A2 and Chinese Type 56s AK-pattern rifles. In June, the first images of Ukrainian troops training with G36s emerged, shared by the Lithuanian Ministry of Defence.

The baltic nations of Lithuania, Latvia and Estonia have been staunch supporters of Ukraine’s and Lithuania’s military has been providing training of various sorts since 2015. Back in April, Lithuania’s Chief of Defence Lieutenant General Valdemaras Rupšys announced that Lithuania would train an undisclosed number of Ukrainian troops on how to use various anti-tank weapons at locations within Lithuania. There has so far been no imagery released of this training.

Lithuania’s Military Academy has also provided a distance learning course online for junior leaders and at the end of October it was announced that 120 junior officers had received training across 4 two-day courses.

In the summer an in-person course that has seen Ukrainian personnel travel to Lithuania for training was established. A course at the Division General Stasys Raštikis Lithuanian Armed Forces School ended in early June. The four week course included weapons handling and marksmanship, map training, fieldcraft and tactics. Organised as part of the NATO Defence Education Enhancement Program (DEEP) it was during these courses Ukrainian personnel have been seen training with Lithuanian G36s.

*Ukrainian troops training in Lithuania (Lithuanian MoD)*

Additionally, Lithuanian instructors have also been training Ukrainian personnel in other countries including the UK. It was announced on 19 October, that a team of military instructors formed from members of the Lithuanian Armed Forces Great Hetman Jonušas Radvila Training Regiment, Division General Stasys Raštikis Lithuanian Armed Forces School, General Adolfas Ramanauskas Warfare Training Centre and the Military Medical Service had joined a multi-national training effort providing basic military training for Ukrainian troops at bases in the UK.

In mid November it was announced that instructors from Ukraine had also taken part in an international instructor course. The course reportedly covered training techniques, weapons training, instruction organisation. The Lithuanian Ministry of Defence also noted that throughout December, there had been more specific courses for Ukrainian personnel on CBRN-contaminated operational environments, courses on UAVs and on intelligence collection from open sources.

Summarising the training provided the Lithuanian Ministry of Defence said 18 different courses had been delivered including: basic individual skills, junior officer command, instructor, special forces, demolition and demining courses. Operators and maintenance for different types of military equipment were also trained.

Lithuania adopted the HK G36 in 2007 and has used several variants including the G36KV1 and the G36KA4M1. None of the photographs show the rifles mounted with optics and in three of the photographs the rifles can be seen fitted with Heckler & Koch’s adjustable blank firing attachment for the G36.

In early December Lithuania announced that in 2023 training of Ukrainian troops would be stepped up with 1,100 personnel to be trained in Lithuania. Part of the courses scheduled in 2023 will be a part of the new European Union’s Military Assistance Mission Ukraine (EUMAM Ukraine).

PK-14 Directional Mines In Ukraine

Recently another interesting anti-tank mine was spotted in use in Ukraine. The Estonian PK-14 or M14 directional mine appeared in photographs which were shared online around 9 September. The PK-14 is a directional mine capable of penetrating about 50mm of armour at a distance of 50 meters.

*Photos of the PK-14 in the field were shared for the first time on 9 September (via Social Media)*

Unlike the German DM22, which is also in service with Ukrainian forces, the PK-14 utilises the Misznay–Schardin effect with 1.5kg charge of PBX used to create an explosively formed penetrator. The PK-14 is capable of damaging most light IFVs and AFVs. It can be set up on a small tripod or even mounted to a tree, telephone poll or post – useful for attacking targets from above.

The Estonian defence company who manufactures the mine list it as both the PK-14 and M14. The mine is produced by Terramil under license from another Estonian defence company, Eesti Arsenal, who also offer several training systems.

*The PK-14 assembled (nucking_futs_yuri)*

*The PK-14 assembled, tripod in the tall configuration (nucking_futs_yuri)*

*The PK-14 assembled, tripod in the low configuration (nucking_futs_yuri)*

The PK-14 has a diopter sight which attaches to the top of the mine and allows it to be laid across the expected path of a target. The sight itself is a inexpensive moulded plastic tube with a narrow aperture which was described to us by an American serving with the Ukrainian armed forces as looking “like a scope you would find on a cheap toy gun at the corner store”. The mine’s casing is cleverly designed with a series of grooves that allow the sight to be slid into place and for the mine itself to be mounted on its tripod.

*The PK-14’s sight tube (nucking_futs_yuri)*

This instructional video from the manufacturers shows how the mine can be set up. The mine is command-initiated using a shock tube integrated system (STIS). This means that the mine isn’t tripped by a wire like the German DM-22 or by movement as in the Russian PTKM-1R, but in person by an operator. In practice the operator would set up the mine at a location the enemy is expected to pass, unspool the shock cord back to a concealed position and wait for the enemy vehicle to move within range of the mine.

In theory it is possible to rig the mines up with a makeshift pressure plate detonation system you could take the pressure plate from a conventional anti-tank mine like a TM-46 or TM-57 and wrap some detcord with a blasting cap at the end around it so when a vehicle rolls over it detonates the mine. The mine can be set up to strike from above so it hits the tank’s weak top armour or buried in the middle of the road so it can strike up through the vehicle’s belly armour.

*The PK-14’s basic components (nucking_futs_yuri)*

Special thanks to nucking_futs_yuri, who is best known as the turret gunner who ran an M2 Browning and was handed some AT4s by his vehicle crew when he called for more ammunition in a recent viral video. Yuri has provided photos and video of a PK-14 in his units inventory. Check out his video showing the components of the mine here.

It’s a small, affordable mine but it is currently unknown how many PK-14 mines have been sent to Ukraine but Estonia, along with the other Baltic states, has been a significant supporter of Ukraine since before Russia’s invasion in February. Estonia began procuring the mines for the Estonian Defence Force in 2015.

nucking_futs_yuri’s video showing the components and set up of the PK-14

In terms of how they may be deployed in Ukraine, the small size and light weight of the PK-14 may be useful for small Ukrainian reconnaissance and special forces teams operating behind Russian lines. Yuri explained that they’re preferred over convention Soviet TM mines as they’re lighter, he stated that:

“normally we each take 2 or more with us, set up our ambush and wait. We could mount them high if need be and get the top of the turret or even bury them in the middle of the road… so it explodes under the center of the tank.”

That innocuous looking tub the Ukrainian soldier is holding out is an Estonian PK-14 Directional Mine.
