M86 Pursuit Deterrent Munition
Encyclopedia
The M86 Pursuit Deterrent Munition (PDM) is a small US
anti-personnel mine
intended to be used by special forces
to deter pursuing enemy forces.
It functions like a small hand grenade
, featuring a pin and fly-off lever. It is based on the M67/M72 ADAM
artillery deployed mine. Once the pin is pulled and the lever has been ejected a timer is started. After 25 seconds, seven tripwire
s are launched from the mine to a maximum distance of 6 meters. The mine then performs an electronic self check, and is fully armed 65 seconds after the battery
is activated. When any of the tripwires is touched, the mine activates, a liquid propellant
charge launches the mine 1 to 2 m into the air. The M43 fragmentation
warhead
detonates - breaking the mine into 600 fragments. The mine self-destructs after four hours, or after the battery reaches a certain level. If it fails to detonate, the battery will discharge over approximately 14 days, rendering the mine inactive.
The mines are normally issued in pairs and carried in a special bandolier
