Marines with Company A, 1st Reconnaissance Battalion, 1st Marine Division, lay down suppressive fire, allowing a breacher in their team to plant an improvised bangalore torpedo by concertina wire during a rocket shoot and fire team assault training exercise aboard Marine Corps Base Camp Pendleton, Calif., Sept. 16, 2015. The overall goal of the training was to expose the Marines to multiple weapons systems and provide them with the experience needed to employ them in deployed environments.
