Lesson plan

OZM

The OZM-3, OZM-4 and OZM-72 are Soviet manufactured bounding type anti-personnel mines. They are fragmentation-barrier mines, which in the Russian and other post-Soviet armies as informally called "frog mine" or "witch". They are normally painted olive green, and issued with a spool of tripwires and two green painted wooden or metal stakes for affixing the tripwires. Both 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 a variety of fuzing options are possible.
