Soviet -designed 100-mm anti-tank gun^[source]

tripod-mounted man-portable, 73mm caliber recoilless gun^[source]

2A19 or T-12 is a Soviet -designed 100-mm anti-tank gun . It was the first anti-tank gun to adopt a smoothbore barrel, and to introduce modern armor piercing shot, like the APFSDS . It uses long projectiles that are more powerful than its caliber suggests. The T-12 served as the primary towed anti-tank artillery in the Soviet and Bulgarian armies from the early 1960s to the late 1980s.^[source]100 mm anti-tank gun T-12 · Lead; only the objects and conditions stated in this passage

The T-12 was designed by the construction bureau of the Yurga Machine-Building Plant as a replacement for the BS-3 100 mm gun . The first serial examples were produced in 1955, but the T-12 entered service only in 1961. Its special feature was the use of a smoothbore gun. The T-12 was typically deployed in the anti-tank units of armored and motor rifle regiments to protect flanks against counter-attacks during rapid advances.^[source]100 mm anti-tank gun T-12 · History; only the objects and conditions stated in this passage

By the mid-1990s, modern western tanks' frontal armor protection could no longer be penetrated by a 100 mm gun. The 100 mm caliber ammunition had reached the limits of what could be achieved with it. For a static anti-tank that cannot move to attack the sides of an opponent this is particularly problematic. Today, the T-12 is used mostly in the role of ordinary artillery, using FRAG-HE shells. The T-12 was planned to be superseded by the 2A45 Sprut-B 125 mm smooth bore anti-tank gun.^[source]100 mm anti-tank gun T-12 · History; only the objects and conditions stated in this passage

Another reason to use a smoothbore barrel for armor piercing shot, is that smoothbore guns allow for higher pressures, and thus higher projectile speeds. The result is that the T-12 fired a conspicuously long APFSDS projectile. This BM2 shot (see picture) had a diameter of 38 mm (1.5 in) and used 8.75 kg (19.3 lb) of propellant instead of less than 6 kg (13 lb) for the existing Soviet tank gun. It was fired at a muzzle velocity of 1,540 m/s (5,100 ft/s) as opposed to only 900 m/s (3,000 ft/s) for the usual armor piercing shot. At 1,000 m (3,300 ft) this improved armor penetration from 185 mm (7.3 in) to 230 mm (9.1 in), enough to penetrate most NATO tanks of the period.^[source]100 mm anti-tank gun T-12 · Description / A revolutionary smoothbore gun; only the objects and conditions stated in this passage

In 1958 Nikita Khrushchev saw the T-12 and was so enthusiastic about the gun, that he wanted it placed in the T55 . However, the long ammunition would not fit in the existing Soviet medium-tank turrets. Therefore, the 115 mm U-5TS gun of the T-62 was developed with a larger caliber, so it could use more propellant while not requiring the very long T-12 cartridges.^[source]100 mm anti-tank gun T-12 · Description / A revolutionary smoothbore gun; only the objects and conditions stated in this passage

The T-12 used the carriage of the 85 mm anti-tank gun D-48 . In fact the only difference between the T-12 and the D-48 was the barrel. Both can be told apart by the muzzle brake , which becomes wider towards the end of the D-48's barrel, but has the same width throughout for the T-12 and MT-12. The wheels of both D-48 and T-12 are secured by six bolts. The carriage of the T-12 did not allow it to be towed cross-country by fast tracked vehicles. It was therefore usually towed by trucks. This limited the T-12's cross country movement to only 15 km/h (9.3 mph).^[source]100 mm anti-tank gun T-12 · Description / Other charactertistics; only the objects and conditions stated in this passage

The standard equipment of the T-12 includes multiple sights . The indirect aiming mechanism consists of the S71-40 mechanism with panoramic PG-1M sight. The OP4M-40U sight is used for direct fire. The APN-5-40 or APN-6-40 are used for direct fire by night.^[source]100 mm anti-tank gun T-12 · Description / Other charactertistics; only the objects and conditions stated in this passage

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 (7,200 ft) (HEAT) or 4,000 m (13,000 ft) (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. 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.^[source]100 mm anti-tank gun T-12 · Variants / Romania; only the objects and conditions stated in this passage

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 (5,900 ft).^[source]100 mm anti-tank gun T-12 · Variants / People's Republic of China; only the objects and conditions stated in this passage

The SPG-9 Kop'yo ( Russian : СПГ-9 Копьё , transliterated: Stankovyi Protivotankovyi Granatomet "Kop'yo" - Easel Anti-tank Grenade Launcher "Spear") is a tripod-mounted man-portable, 73mm caliber recoilless gun developed by the Soviet Union . It fires fin-stabilized, rocket-assisted high explosive (HE) and high-explosive anti-tank (HEAT) shaped charge projectiles similar to those fired by the 73mm 2A28 Grom low pressure gun of the BMP-1 armored vehicle. It was accepted into service in 1962, replacing the B-10 recoilless rifle .^[source]SPG-9 · Lead; only the objects and conditions stated in this passage

The projectile is launched from the gun by a small charge, which gives it an initial velocity of between 250–400 metres per second (820–1,310 ft/s). The launch charge also imparts spin to the projectile by a series of offset holes. Once the projectile has traveled approximately 20 metres (66 ft) from the launcher, a rocket motor in its base ignites. For the PG-9 projectile, this takes it to a velocity of 700 metres per second (2,300 ft/s) before the motor burns out.^[source]SPG-9 · Description; only the objects and conditions stated in this passage

The SPG-9 is heavy, ~60 kilograms (130 lb), and normally transported by vehicle, and carried into position by its two person crew. It can be deployed in about a minute. The weapon is in service with a large number of armed forces, and a variety of ammunition is produced; however, they are mostly copies of the original Soviet PG-9 HEAT and OG-9 fragmentation high explosive (Frag-HE) rounds.^[source]SPG-9 · Description; only the objects and conditions stated in this passage
