HomeMINES and CHARGESSOVIET & BALKANRussia

OZM mines are bounding fragmentation mines which may be field fabricated or factory assembled.
The improvised mines are assembled by using mortar or artillery shells, with a special propellant base designed for this purpose.
This type of mine was used in large quantities against the Germans in World War II.
OZM-type mines are initiated by the closing of an electrical circuit, pressure on a fuze, or by pulling a wire attached to the fuze.
This sets off the propellant which forces the mine out of the ground and ignites the delay element.
The delay burns until it explodes the detonator.
The mines explode 1.5 to 2.4m (5 to 8ft) above the ground.

OZM-3 :



Earth filled in around the mine during emplacement serves to guide it and thus eliminates the need of a barrel.
Although primarily an antipersonnel mine, some OZM mines are capable of disabling a tank if exploded beneath it.

This mine was also adopted by the East German NVA, see OSM-3.
