YaM-5 box mine
From Wikipedia, the free encyclopedia
The YaM-5 (anti-tank mine 5 kilograms) was a Soviet wooden cased anti-tank blast mine. Several different variants of the mine were produced using differing varieties of wood. The mine consists of a rectangular wooden box with a hinged lid that overlaps the front of the mine. A slot in the hinged lid's side through which a MUV pull fuze is placed. A wooden pressure bar is sometimes used on the edge of the lid above the slot. A nail is placed horizontally through the loop of the MUV fuze's striker retaining pin and two loops on the bottom of the lid's slot.
A YaM-10 was also produced, it was simply a scaled up version of the YaM-5.
The wooden case was normally painted olive green, gray or white.
The mine was frequently used with anti-handling devices.
Downward pressure on the lid causes forces the nail downwards, withdrawing the striker retaining pin, detonating the mine.
