A Mine-clearing line charge lies off to the side as an Amphibious Assault Vehicle rolls past during a deliberate defense breaching exercise Jan. 22 at LZ Dodo in the Central Training Area. The MCLC is a line of high explosives projected into a mine field and detonated to trigger nearby mines allowing safe passage of ground troops afterward. The AAV is with Amphibious Assault Company, Combat Assault Battalion, 3rd Marine Division, III Marine Expeditionary Force. (U.S. Marine Corps photo by Lance Cpl. Stephen D. Himes/Released)
