Description: The mine consists of a rectangular box with a cover securely fastened by friction tape. Two holes are roughly punched in the cover through which a grenade fuze or detonator projects. The grenade fuze projects approximately 3/4 inch, projection of detonator is unknown.

Contained in the box are one Japanese type (91) hand grenade and twelve blocks of 1/3 aluminum powder and 2/3 RDX. Each block is 1 1/2 by 3/4 inches wrapped in waxed pa-per. Color is black. The grenade and blocks, 1/3 aluminum powder and 2/3 RDX, are firmly held in place by waxed paper.

Employment: Can be used as an antitank mine when fuzed with the armed grenade. With a pull or tension detonator it can be used as an antipersonnel mine or booby trap.

Operation: As an antitank mine: Safety pin on fuze is removed. When it is hit by a sharp blow the striker breaks a shear wire and penetrates the primer. After a delay of 4 to 5 seconds the bursting charge explodes setting off the charge.

As an antipersonnel mine or booby trap: A pull igniter with detonator is inserted into the charge. When the trip wire is pulled, the flash will fire the detonator which in turn sets off the explosive and hand grenade.
