OZM-4fragmentation mineOZM-4 is a high-explosive, fragmentation bounding antipersonnel landmine that is normally tripwire initiated. The OZM-4 replaced the OZM-3 and is larger. Initiating the fuze ignites a propellant charge in the base of the mine, which blows out a base plug to propel the mine body into the air. A tether cord then initiates the internal mechanical fuze, firing the detonator and main charge to shatter the steel body into fragments.Diameter: 90mm Height: 140mm Weight: 5kg Explosive: 170g Range: 100m Explosive/filler type: TNTRussian Federation
