The MT-LB (Russian: Многоцелевой Тягач Легкий Бронированный, romanized: Mnogotselevoy tyagach legky bronirovanny, literally "multi-purpose towing vehicle light armored") is a Soviet multi-purpose, fully amphibious, tracked armored fighting vehicle in use since the 1970s. It was also produced in Poland, where (starting in the mid-1990s) its YaMZ engine was replaced by a Polish 6-cylinder SW 680 diesel engine.
