M1 ANTI-TANK PRACTICE MINE:

The M1 consists of three components: an empty mine body, a spider, and a fuze. The parts are similar in construction to the high explosive mine except the body has five one-inch holes equally spaced around the side. The explosive filling consists of a .32 caliber blank cartridge in the fuze, 100 grains of red phosphorous, and 60 grains of black powder.

M1B1 ANTI-TANK PRACTICE MINE:

The M1B1 is made of sheet metal and resembles the service mine except that the filling hole is in the bottom of the mine body. The body is sand-filled to weight before it is issed for use in practice. Four sections are cut out of the top of the body near the fuze well to permit the passage of smoke.

M8 (T4) ANTI-PERSONNEL PRACTICE MINE:

The M8 is similar in appearance and operation to the M2A3. Obsolete bodies of M2 and M2A1B1 mines are utilized. This mine does not contain a propelling charge in the base as does the standard H.E. mine. The propelling charge for projecting the card-board projectile into the air is contained in the igniter charge on the base of the fuze. The projectile contains a 12-gauge shot gun charge loaded with black powder to simu-late the action of a live mine. The primer and igniter, which has a delay of approximat-ely 5 seconds, is activated by Fuze, mine, combination, M10 (T14). This fuze is a three-pronged firing device similar to the Fuze, mine, combination, M6.
