Use:

The antipersonnel practice mines M8 and M8A1 simulate the M2 series of antipersonnel mines and are used for training in the proper methods and precautions to be observed in the care, handling, laying, booby trapping, arming, and disarming of the M2 and M15 series mines.



Description:
General. The metal parts of these mines are similar to those of service mine M2A4. The M8 mine uses a cardboard projectile containing a spotting charge. The M8A1 uses smoke pellets to indicate activation of the mine. These practice mines may be used many times by replacing the fuzes and separately requisitionable components.



The M8 requires replacement of a mine cap (metal) and cardboard projectile which contains a spotting charge. The M8A1 requires replacement of a mine plug (polystyrene) and smoke pellets.
Difference between models. The M8 practice mine ejects a cardboard projectile containing a delay and a spotting charge of black powder which bursts in the air. The M8A1 indicates functioning by emitting yellow smoke from the top of the main body. The practice mine M8 uses either fuze mine combination practice M10 or M10A1. The practice mine M8A1 uses the M10A2 fuze.

Functioning:
Mine M8 with Fuze M10 or M10A. The fuze firing mechanism is activated by an applied load of 8 to 20 pounds on any of the prongs or by a pull of 3 to 10 pounds of the trip wire. The fuze firing train ignites the delay element in the projectile and also propells it about 2 meters into the air. The delay initiates the spotting charge which explodes with a loud report and emits smoke.
Mine M8A1 with Fuze M10A2. The fuze firing mechanism is activated by an applied load of 8 to 20 pounds on any of the prongs or by a pull of 3 to 10 pounds of the trip wire. The fuze firing train ignites the yellow smoke pellets through a 4 to 5 second delay. The plastic plug is propelled in the air allowing the yellow smoke to be emitted from top of container.
