Members of Company K, 3rd Battalion, 25 Marine regiment, Marine Reserves, Pittsburg, Pennsylvania, rehearse live-fire operations, and practice call-for-fire missions using the Virtual Battle Space III (VBS III) simulator. The marines are rehearsing for a real life mission that will happen at Camp Grayling’s 40 complex range as part of Northern Strike 16, which will involve mortars, artillery, and close air support with A-10's. Northern Strike 16 is a National Guard Bureau-sponsored exercise uniting approximately 5,000 Army, Air Force, Marine, and Special Forces service members from 20 states and three coalition countries during the first three weeks of August 2016 at the Camp Grayling Joint Maneuver Training Center and the Alpena Combat Readiness Training Center, both located in northern Michigan. The exercise strives to provide accessible, readiness-building opportunities for military units from all service branches to achieve and sustain proficiency in conducting mission command, air, sea, and ground maneuver integration, and the synchronization of fires in a joint, multinational, decisive action environment.
