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.
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 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.
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.
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.
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.”
