Firefighters from the Michigan Air National Guard and Estonian, Latvian and Bulgarian air forces battle a controlled burn aircraft fire at the Alpena Combat Readiness Training Center in Alpena, Mich., July 22, 2019. JP-8, a fuel used in U.S. military aircraft, burns at between 800 and 1,500 degrees Fahrenheit. Northern Strike 19 is a National Guard Bureau-sponsored exercise uniting service members from more than 20 states, multiple service branches and numerous 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 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, together with the synchronization of fires in a joint, multinational, decisive action environment.
