The FMK-3 is a fibreglass cased Argentine anti-tank blast mine. It is produced by Direccion General de Fabricaciones Militares. The mine actually uses a FMK-1 anti-personnel mine as a fuze, the FMK-1 is modified with a pressure cap to increase the activation pressure. Argentina's stock of FMK-1 mines was modified in 2003 to prevent their use as anti-personnel mines, this involved welded an additional plastic pressure cap onto the mine. The mine has very little metal content, although an optional detection ring is provided with the FMK-1.
It is found in the Falkland Islands.
