Walkaround: MT-LB - Многоцелевой Тягач Легкий Бронированный /2 versions/

A picture walkaround of MT-LB. Two different versions are photographed, both with minor differences. The MT-LB (Russian: Многоцелевой Тягач Легкий Бронированный, Mnogotselevoy Tyagach Lekhko Bronirovannyi / multi-purpose light-armoured towing vehicle) is a Soviet multi-purpose fully amphibious auxiliary armoured tracked vehicle, which was first introduced in the late 1960s. Initially, the vehicle was known as the M 1970 in the west. In the 1970s, the Soviet Central Auto and Tractor Directorate began a development program to replace the AT-P series of artillery tractors (which were based on the ASU-57 airborne self-propelled gun) with a new generation of vehicles. The MT-L was developed to meet this requirement based on the PT-76 amphibious light tank chassis. The MT-LB is the armoured variant of the MT-L. Entering production in the early 1970s, it was cheap to build, being based on many existing components, e.g. the engine, which was originally developed for trucks. It is built at the Kharkov Tractor Plant and under license in Poland by Huta Stalowa Wola and Bulgaria.
