The TM-44 was a circular metal-cased Soviet anti-tank landmine used during the Second World War.
The mine's case consisted of a short cylinder with the entire top surface being used as a pressure plate.
The earlier TM-41 was used widely between 1941 and 1942, but production was discontinued because of the lack of metal available to Soviet industry.
The fuze's lock balls are forced out of position by the pressure, releasing a striker, which triggers a detonator, then a booster and then the mine's main charge.
The mine was prone to rusting, exposing the MV-5 fuze which could be triggered by as little as 1 to 3 kilograms of pressure.
