The training included tactical movements, posting security, breaching doorways, clearing rooms and a variety of other battle drills. Exercise 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.
