The video with the unusual weapon was published by journalists of the Military Courier on Telegram. It follows that the MT-LB is used as a self-propelled carriage for an anti-tank gun.
It is worth noting that the occupiers were the first to install Rapiers on MT-LB due to the lack of armor. Ukrainian engineers borrowed this solution from them. A large number of Rapiers and Motoligas have remained in Ukraine since the Soviet era. Thus, the practice of their “crossing” may become widespread.
The MT-12 Rapier was designed by Soviet designers in the 1960s. It is designed to repel tank attacks. The gun can fire 100-mm anti-tank ammunition.
