OZM

The OZM-3, OZM-4 and OZM-72 are Soviet-manufactured bounding-type anti-personnel mines, classed as fragmentation barrier mines and informally called the frog mine or the witch in the Russian and other post-Soviet armies. They are normally painted olive green and issued with a spool of tripwire and two green painted stakes for anchoring the tripwires. The OZM-3 and OZM-4 have cast iron fragmenting bodies, while the OZM-72 also contains preformed steel fragments, and all three are issued with empty fuze wells so that a variety of fuzing options can be fitted.
