TM-41 mine

The TM-41 was a circular, metal-cased Soviet anti-tank landmine used during the Second World War.

The mines case consisted of a short cylinder with the entire top surface being used as a pressure plate.

It was normally painted olive drab and was broadly similar to the larger, later, TM-44 mine.

The mine could be waterproofed with washers and laid underwater, where it can remain operational for two months.

Pressure on the pressure plate resulted in lock balls being force out of position, releasing a striker, which triggers a detonator, then a booster and then the mines main charge.
