Marines with Bravo Battery, 1st Battalion, 12th Marine Regiment, hastily reload an M777 howitzer with a 155 mm artillery shell during a multiple-rounds fire mission as a part of a two-day dual-fire training exercise at Schofield Barracks, Hawaii, Nov. 13, 2013. The M777s fired alongside M327 Towed-Rifled Mortar Systems to eliminate the possibility of short-range threats on the battlefield and to expand the capabilities of the battery as a whole.
