МТ-12 - 2A19 (T-12) Soviet smoothbore 100-mm anti-tank gun 2A19 or T-12 is a Soviet smoothbore 100-mm anti-tank gun, which served as the main Eastern Bloc towed anti-tank gun from 1955 until the late 1980s. The gun requires a crew of six: commander, driver of the towing vehicle, gun layer, loader, and two ammunition crewmen. When the MT-LB is used as the transporter, 20 rounds are typically carried (10 APFSDS, 4 HE-Frag, 6 HEAT). Since the weapon is a smoothbore, all the ammunition is finned for accuracy
