14.5 mm KPVT Tank machine-gun is a powerful automatic weapon mounted on the armoured vehicles, war boats, movable and stationary mounts.

The KPVT is used for armoured vehicle installations, boats, movable and stationary mounts and various antiaircraft mounts. It features a shorter receiver and a heavier barrel jacket. The KPVT also uses a 50-round belt instead of the original 40-round belt. KPVTs are the primary armament of the wheeled BTR-60PB/70/80 series armoured personnel carriers and BRDM-2 armoured reconnaissance vehicles.

It is intended for fight against light-armoured targets, fire weapons and alive force located in light shelters at the distances of up to 2000 m, as well as air targets at the distances of up to 2000 m at the heights of up to 1500 m.

Cartridges with armour-piercing-incendiary bullet B-32, armor-piercing-tracer bullet BZT and incendiary bullet of instant action MDZ are used for firing at surface and air targets. Feed of cartridges (right-hand or left-hand) is performed from the metallic belt.
