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 1960s until the late 1980s.


The T-12 entered service in 1961[1], replacing the BS-3 100 mm field gun. It was typically deployed in the 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, which has a 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The weapon was planned to be superseded by the 2A45 Sprut-B 125 mm smooth bore anti-tank gun.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, 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 during flight.

The standard equipment consists of the panoramic PG-1M sight 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.


Note: penetration numbers for RHA at 90 degrees.

According to Jane's Armour and Artillery,[4] the following countries have or had the T-12 and/or MT-12 in service:

Current operators[edit]

Former operators[edit]



  • 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: Tun antitanc calibrul 100-mm Model 1977) and is normally towed by the DAC 887R truck.[5] It can also be towed with the DAC 665T truck. The Model 2002 is an improved version, fitted with the automatic fire control system TAT-100.[6]

People's Republic of China[edit]

  • Type 73 - This appears to be a copy of the Soviet T-12.[7]
  • 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.[8]
