A diagram of a YaM-5 anti-tank mine from a US army publication.
The YaM-5 (anti-tank mine 5 kilograms) was a Soviet anti-tank blast mine with a wood case. Various wood was used. 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 an MUV pull fuse 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 fuse's striker retaining pin and two loops on the bottom of the lid's slot.
A YaM-10 was also produced, it was 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 forced the nail downwards, withdrawing the striker retaining pin detonated the mine.
