PMA-3 mine

The PMA-3 is a Yugoslavian blast resistant minimum metal anti-personnel mine. It is circular, consisting of a plastic upper and lower half joined together by a rubber cover. A safety collar is normally wrapped around the outside of the mine, preventing the upper half of the mine tilting when in transit. Once deployed the safety collar is removed. Sufficient pressure on the top surface of the mine causes it to tilt. The tilting drives a pin through a friction sensitive compound triggering the mine's detonator and then main charge.

Straight downward pressure does not have the shearing component needed to trigger the mine, this gives the mine blast resistance, since blast overpressure bears down evenly on the top surface of the mine.

The mine has a relatively low explosive content so will maim rather than kill. Its blast resistance combined with the lack of metal in the mine make it extremely difficult to clear.

The mine is found in Albania, Bosnia, Cambodia, Chad, Chile, Croatia, Kosovo, Lebanon, Namibia and Peru
