U.S. Army Sgt. Christopher Harmon, from Bravo Troop, 5th Squadron, 3rd Battalion, 1st Brigade Combat Team, 73rd Cavalry Regiment, 82nd Airborne Division, executes a shotgun breach of a door lock during a house by house clearance operation in Aksabah, Iraq, Aug. 17, 2007. The Army recently approved a new anti-material cartridge, the M1030. The M1030 is designed as a breaching munition, used for defeating wooden doors, deadbolts, knobs, hinges and padlock hasps. The design of the munition minimizes ricochet hazards currently associated with buckshot breaching and provides a much safer alternative to the Soldier.
