Introduced in the early 1960s, the T-12 is a very technologically advanced dinosaur. A towed anti-tank gun in the era of anti-tank missiles, main battle tanks and attack helicopters. However, it is a smoothbore gun which fires tungsten-core APFSDS projectiles, perfectly capable of defeating most tanks in the world's armouries. It equips the Soviet Army's motorised infantry anti-tank battalions, as well as similar units in the Oceanykan Peoples' Army.
