The TM-46 mine is a large, circular, metal-cased Soviet anti-tank mine. It utilises either a pressure fuze or tilt-rod, which is screwed into the top. Anti-tank mines with this type of fuze were capable of inflicting much more damage to armored vehicles. The TMN-46 is a variant of the mine fitted with a secondary fuze well on the bottom (where it cannot be seen) which is slightly off-set from the centre of the mine. This secondary fuze well can be fitted with a pull-fuze which functions as an anti-handling device. The mine was used by the North Vietnamese forces during the Vietnam War, and is found in many countries in Africa, the Middle East and South East Asia.
