The BTR-70 is an eight-wheeled armored personnel carrier (Russian: бронетранспортер, BTR stands for Bronetransportyor literally "armoured transporter"), originally developed during the late 1960s under the industrial designator GAZ-4905. On August 21, 1972, it was accepted into service and would later be exported to the Warsaw Pact and other allies. Introduced as a successor to the earlier BTR-60, it most closely resembles a BTR-60PB. Improvements include heavier armor plating and tires less prone to puncture. In other respects, the vehicle is very similar to the BTR-60PB, both vehicles having a roof-mounted turret equipped with a heavy machine gun and a secondary co-axial PKT machine gun, but with a more powerful petrol engine configuration. It is used by the Horde and the Axis
