Lance Cpl. Faustino J. Camilo prepares to load a M231 primer into the M777 Howitzer cannon during a battery-level fire exercise at Camp Pendleton, Calif., Feb. 10, 2016. The battery participated in a fire exercise in preparation for their upcoming deployment with the 31st Marine Expeditionary Unit. This exercise was the first time the battery used the Digital Firing Control System, a computer that shows grid coordinates of targets and accompanying information. This system is important because it provides a faster response time than using iron sights to fire the howitzer. Camilo, from Brunswick, Ga., is an artillery cannoneer with Battery F, 2nd Battalion, 11th Marine Regiment, 1st Marine Division. (U.S. Marine Corps Photo by Lance Cpl. Justin E. Bowles) - Lance Cpl.
