National Training Center (NTC): Conventional Threat Antipersonnel (AP) Mines (OZM-3). (CTC Notes).

As NTC continues to implement the contemporary operational environment (COE), the Opposing Force (OPFOR) will also adjust its inventory of battlefield effects to match worldwide threats and challenge the rotational units. The OZM-3 marks the arrival of the AP mine to NTC. Units should realize that AP mines are a realistic threat and will be replicated during their rotations. Units do not train on or emplace AP mines but must react to their presence on the battlefield.


The OZM-3 can be detonated with a variety offuses, including trip wires and electrical command. The mine weighs 3.0 kilograms and has a cylindrical cast-iron body that is sent into the air by a small charge at the base of the mine. Triggered by a delayed charge, the body of the mine explodes approximately 1.5 meters off the ground. The fragmentation results in a casualty radius of 25 meters. Because of its metal content, the OZM-3 can be readily detected by demining/detection equipment.

Rules of Engagement (ROE)

There are no ROE changes to explosive- and mechanical-reduction techniques. For manual reduction, proper grappling techniques (according to FM 20-32, Mine/Countermine Operations) will result in the AP mines being detonated without casualties. Failure to adhere to this procedure will result in casualty assessment of the grappler. If a grappling hook hits a mine, the mine will be assessed as destroyed along with the grappling hook and a small portion of the grappling hook line. The assessment of the line will be based on the materiel type and how the line is laid near the mine.
