black powder charge in the mine body. The blast from
the black powder expelling charge blows off the fuze
assembly, the cover assembly, and the camouflage
material which covers the mine. The pressure created
by the burning black powder charge causes the primer
to ignite which, in turn, ignites the delay assembly, the
relay assembly, the booster, and the high-explosive
charge (H6) of the mine.
(d) The detonation of the high-
explosive charge blows the body of the mine apart and
propels the steel dish upward through the belly of the
tank or other vehicle above it.
b. Use. The mine is effective against vehicles
which straddle the mine (tilt rod action), as well as those
which run directly over it (pressure action).
