The Ministry of Defense of Ukraine published the combat work footage of one of the artillery units of the 93rd mechanized brigade of the Armed Forces of Ukraine, which used a 100mm MT-12 Rapira anti-tank gun.
The authors of the Ukraine Weapons Tracker Twitter profile in their turn noticed the following detail: the servicemen loaded their gun with Bulgarian 100mm 3UBK2 HEAT FRAG projectiles, manufactured in 1987.
The authors of the Facebook post by the Ministry of Defense of Ukraine called the MT-12 gun an "artillery sniper rifle", meaning that Rapira is capable of accurately hitting enemy armored vehicles with an armor-piercing projectile at a distance of up to 1.5 km.
Continuing to develop this metaphor, then it is worth expressing more precisely: the MT-12 Rapira anti-tank gun is a "mass artillery sniper rifle".
Because publicly available sources indicate that Rapiras are now used not only by the 93rd Brigade of the Armed Forces of Ukraine, but also by the Marine Corps of the Ukrainian Navy and the National Guard of Ukraine. Accordingly, 100-mm shells have to be imported constantly and intensively. And it seems that Bulgarian companies in this case are by no means the only suppliers of this type of ammunition.
