The M14 is a non-metallic, blast-type AP mine consisting of a main charge of tetryl (1 ounce). The mine is cylindrical in shape, 2-3/16 inches in diameter and 1-9/16 inches high weighing approximately 3-1/2 pounds. The M14 is not designed to kill, but to incapacitate. The M14 AP mine has been modified by gluing a metal washer to the bottom of the mine. The modification was directed to improve the detectability of the mine. Unmodified mines are not authorized for use by US forces.
These were carried by SOG teams as a method of deterring tracker team and protecting a night sleeping position. The items you see here are a replica M14 and a genuine issue training M14 mine (the one in light blue).
