2A45

2A45 is a Soviet era self-propelled anti-tank gun. It was developed in the late 1970s and early 1980s. The 2A45 is based on the chassis of the PT-76 light amphibious tank, but features a significantly larger and more powerful main gun. Its primary armament is the 2A45M 125mm smoothbore gun, capable of firing a variety of ammunition, including armor-piercing fin-stabilized discarding sabot (APFSDS) rounds and high-explosive anti-tank (HEAT) rounds.

The vehicle is designed for direct fire support and anti-tank roles. Its low profile and relatively good mobility allow it to operate in various terrains. The crew typically consists of three to four members. The 2A45 was intended to provide mobile firepower that could engage modern armored threats effectively. While not produced in very large numbers, it represented an evolution in Soviet self-propelled artillery design, focusing on dedicated anti-tank capabilities with a heavy gun. Production and operational use occurred primarily within the Soviet Union and later some successor states. Details on its exact deployment numbers and combat history are not widely publicized.
