2S14 Zhalo-S

The 2S14 Zhalo-S was built on the BTR-70 armored personnel carrier chassis, with a turret mounting a 85 mm 2A62 gun, which had identical ballistic characteristics and ammunition to the towed 2A55 anti-tank gun. The 2A62 was equipped with a muzzle brake with an efficiency up to 75-80%, capable of firing 20-25 shells per minute. The 2A62 used armor-piercing composite-rigid (APCR) shells, which were exclusive to the gun. The APCR shell had a penetration capability 1.5 times lower than that from a 125 mm D-81 gun. A periscopic sight was provided for aiming the gun, with an R-173 radio station provided for communications.
