When the PMN is emplaced, a 20-minute delay-action spring mechanism arms the pressure plate
fuzing system. The method of arming makes the mine extremely sensitive when emplaced. The mine
cannot be disarmed.
Remarks: The PMN was introduced around 1960 and has been employed on the East German border
as well as in Vietnam.
