The mine consists of a loaded mine body, fuze, and pressure-plate plug. The steel body is cylindrical, with a carrying handle attached to the bottom. Assembled to the mine body is a round pressure plate, 7i/g inches in diameter, containing the reversible pressure- plate plug which covers the fuze well. The pressure plate is supported internally by circular Belleville springs and sealed against moisture by a rubber diaphragm. In addition to the primary fuze well, supplementary fuze wells are located on the side and on the bottom of the mine for use in antilifting or boobytrap purposes.
For boobytraps or anti-removal devices, after the main fuze is installed, any standard firing device may be attached to the supplementary fuze wells by using the Activator M1. This activator is a plastic adapter approximately two inches long, which contains a tetryl booster charge.
No information about functioning.
