OZM
From Wikipedia, the free encyclopedia
The OZM-3, OZM-4 and OZM-72 are Russian manufactured bounding mine type anti-personnel mines.
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.

[edit] Operation
The mines can be activated by a variety of fuzes, including electronic fuzes or command initiation, although they are most commonly fitted with an MUV booby trap switch which is activated by a tripwire.
On firing, a metal base plate remains in the ground, while the mine body is thrown up by a small lifting charge, but remains attached to a strong wire tether. When the end of the tether is reached at a height of approximately 0.5 m, the main charge explodes and scatters fragments of the casing across a wide area.

[edit] Ottawa Treaty
Since the Ottawa Treaty, a number of countries have decided to retain their OZM mines, but convert them to command detonation only by destroying all fuzes which can be indiscriminately activated – potentially by non-combatants or animals. Belarus in particular has decided to keep 200,000 OZM-72.
