U.S. Marine Corps Cpl. Tylerruben Salas, small arms repair technician for Marine Corps Base Camp Blaz, conducts rifle, pre-fire inspections before shooting on Marine Corps Base Camp Blaz, Guam, Sept. 25, 2023. The Marine Corps’ Program Manager for Training Systems will conduct target calibration from Sept. 25 to Oct. 27 and testing from Dec. 4-15. Two of four ranges at the Live Fire Training Range Complex will be equipped with new technology that provide more efficient and effective combat marksmanship training to support combat readiness. The live-fire location of miss and hit or LOMAH technology, replaces the human element of observing and marking targets. The calibration and testing are to ensure that the LOMAH system is working properly. (U.S. Marine Corps photo by Lance Cpl. Garrett Gillespie) - U.S. Marine Corps Cpl.
