The TM-57 mine is a large, circular Soviet metal-cased blast anti-tank mine. It can either be triggered by pressure or a tilt-rod fuze. A development of the TM-46 mine, but with more explosive. It is found in Africa (including Angola and Ethiopia), the Middle East, and South East Asia.
Description The TM-57 has a larger main charge and improved fuzing compared to the earlier TM-46. It is circular with a metal case and a central fuze well. A secondary pull-action fuze MUV-2 (Rus. МУВ-2) or VPF (Rus. ВПФ) pull and tilt fuze can be fitted on the side of the mine, which serves as an anti-handling device. The tilt rod fuze gives the mine improved resistance to blast; it is activated when it is forced to a deflection of 25 to 30 degrees. A training version of the mine that produces smoke is designated the TM-60.
