U.S. Navy aviation structural mechanics with Helicopter

U.S. Navy aviation structural mechanics with Helicopter Sea Combat Squadron Four (HSC-4) “Black Knights,” San Diego, Calif., work on the MH-60S Seahawk helicopter at Alpena Combat Readiness Training Center, Mich, July 27, 2019, during Northern Strike 19.
Northern Strike 19 is a National Guard Bureau-sponsored exercise uniting service members from more than 20 states, multiple service branches, and seven coalition countries during the last two weeks of July 2019 at the Camp Grayling Joint Maneuver Training Center and the Alpena Combat Readiness Training Center, both located in northern Michigan and operated by the Michigan National Guard. The accredited Joint National Training Capability exercise demonstrates the Michigan National Guard’s ability to provide accessibly, 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, together with the synchronization of fires in a joint, multinational, decisive action environment.
