The M6, M6A1 and M6A2 are a series of metal-cased, circular, heavy anti-tank landmines produced by the United States from May 1944 to May 1945.
Because of a lessening need for antitank mines as the Allies went on the offensive in 1944, the T6E1/M6 was not deployed to the European theater.
The mine is normally painted olive green and has a large central pressure plate.
The pressure plate rests on a concertina-like structure, which when enough force is applied is compressed.
Compression results in a transfer plate under the arming plug pressing downwards onto a belleville spring which inverts, flipping the firing pin into the detonator, which triggers the adjacent explosive booster and main explosive charge.
