The T-12 entered service in 1955, replacing the BS-3 100 mm field gun. It was typically deployed in anti-tank units of armoured and motor rifle regiments to protect flanks against counter-attacks during rapid advances.
In 1970 it was replaced in production by the T-12A or MT-12 "Rapira" which features a new smooth bore gun, the 100 mm 2A29 gun, as well as a redesigned carriage and gun-shield to protect the crew from machine gun fire and shell splinters. Thanks to the redesigned carriage with bigger wheel base, the MT-12 can be towed by the MT-LB, at speeds up to 60 km/h on road or 25 km/h cross-country.
The 2A29R "Ruta" or MT-12R is a version with a RLPK-1 radar for engaging targets in a poor visibility environment (smoke/fog). From 1981 the gun could fire laser beam-riding guided missiles 9M117 Kastet (weapon system 9K116) and carried the new designator 2A29K "Kastet" or MT-12K.
The weapon was planned to be superseded by the 2A45 Sprut-B 125 mm smooth bore anti-tank gun. Modern western tanks' frontal armour protection is in excess of what can be penetrated by a 100 mm gun from anything but point-blank range – even using the most modern APFSDS round. For a tank that can manoeuvre to take advantage of the enemy's weaknesses this is less of a problem – but for a weapon that is primarily defensive this is a serious problem. Today the T-12 is applied mostly in the role of ordinary artillery, using FRAG-HE shells.
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, twenty rounds are typically carried (10 APFSDS, 4 HE-Frag, 6 HEAT). Since the weapon is a smoothbore, all the ammunition is finned for accuracy during flight.
The standard equipment consists of the panoramic sight PG-1M for indirect fire, and an OP4M-40U telescope for direct fire. The APN-5-40 or APN-6-40 are used for direct fire by night.
The gun can be fitted with the LO-7 ski gear for travel across snow or swampy ground.

- A407 - This artillery system was designed by Arsenal-Resita and is very similar to the MT-12. It can fire the same range of ammunition as the T-54/55 tank and has a maximum range of 2,200 m (HEAT) or 4,000 m (APC-T). Subversions are the A407M1 and the A407M2. In Romanian Army service, the A407 is known as the 100 mm anti-tank gun M1977 (Romanian language: Tun antitanc calibrul 100-mm Model 1977
People's Republic of China
- Type 73 - This appears to be a copy of the Soviet T-12.
- Type 86 - This is a 100mm smoothbore anti-tank gun that has some similarities with the 85mm Type 56 (D-44). It fires ammunition of the fixed type, including the Type 73 HE, Type 73 HEAT, Type 73 APFSDS and Type 86 APFSDS to a maximum range of 1,800 m.
