PMA-3 was manufactured in the former Yugoslavia and has been
widely used throughout the Balkans. It is also reported to have
been used in Namibia.
PMA-3 is a pressure operated plastic AP blast mine containing
a main charge of 35g Tetryl. The metal content is "very small"
Colour: top of the mine is covered with a flexible rubber cover
that is a dull black when dry. The body of the mine is generally
dark green or black and can only be seen when the mine is inverted.
mine uses an UPMAH-3 fuze with integral detonator.
diameter of the high explosive within the mine is only half
the diameter of the mine (the yellow/orange block shown in the
the side of the mine is stepped on, some people have suffered
only a bruised foot or minor fractures. If the centre of the
mine is stepped on, damage is frequently bad enough to necessitate
a surgical amputation of the lower leg. This mine is designed
to be laid flush to the ground surface because the initiation
relies on the top of the mine tilting and causing friction within
the initiator. It may not operate if it becomes more deeply
buried. But, when the ground becomes soft (after rain) it may
be initiated as the pressure of a footfall compresses the soft
mine has an arming ring that includes a metal spring. The ring
opens but may be left around the mine after arming, Some report
that the presence of the spring makes detection easier. In my
own experience, the spring is undetectable with some metal-detectors.
