 The mine can be deployed by helicopters or ground vehicles or laid by hand.A sustained downward force of approximately ten kilograms on the pressure plate for a minimum of 0.10 seconds compresses the firing spring and cocks the striker.Continuous downward movement allows the trigger assembly to pivot, slowly forcing the air out of an anti-shock bladder and flips the striker down into the stab sensitive M41 detonator, at which point the mine explodes.
