    C – AN OZM4 bounding fragmentation mine with an MUV2 fuze. This mine has a castiron body 91mm in diameter (just over 3½"). It contains 170g TNT. When initiated, the mine body is thrown into the air until it pulls a wire attached to its baseplate tight. The main charge then explodes, stering the area with castiron fragments.
