The MT-LB tracked armored personnel carrier was developed in the mid-1960s and adopted by the Soviet Army at the turn of the 1960s and 1970s. The machine was powered by one diesel engine with a capacity of 240 hp. and accommodated up to 11 paratroopers. The crew consisted of two people: the commander and the driver-mechanic. The main armament of the basic version was a single PKT machine gun of 7.62 mm caliber in the turret in the frontal part of the machine. Transporter MT-LB was originally developed as an artillery tractor for anti-tank guns. 100-mm T-12, but it was relatively quickly used as an armored personnel carrier. Due to the high susceptibility of the MT-LB design to modifications, several dozen different types of special vehicles were created on its basis in the USSR and the Warsaw Pact countries. These include the 9K35-Strieła 10 set (self-propelled anti-aircraft gun), the 2S1 Goździk self-propelled howitzer, the TTLB or MT-LB (Pzj) self-propelled artillery radar, which were used by the GDR army as anti-tank units. MT-LB was very widely exported to many Warsaw Pact countries, as well as Arab and African countries. It has also been involved in many conflicts, including the Afghanistan War (1979-1989), the 1991 Persian Gulf War, and the Second Chechen War.
