ALPENA â Exercise Mobility Guardian 2021, the Air Forceâs largest and longest exercise ensuring readiness to move military personnel and equipment in combat operations, is scheduled to begin at Alpena Combat Readiness Training Center on May 15. More than 1,800 exercise participants will operate 18 mobility aircraft at six locations in Michigan and Wisconsin through May 27 in order to validate Air Mobility Commandâs readiness to provide Rapid Global Mobility for America and the Joint Force. Additional exercise locations include Oscoda-Wurtsmith Airport, Michigan and Volk Field, Wisconsin, with Air National Guard units from Minnesota, Wisconsin, Michigan and Ohio flying in the exercise. The biennial exercise includes AMCâs first large-scale integration of cutting-edge concepts to advance warfighting capabilities. Multi-Capable Mobility Airmen will demonstrate speed and agility while enabling refueling and re-arming of fighter aircraft in an austere location. Aircrew and mission planners will use specialized computers and communications aboard aircraft to rapidly share data, promoting increased awareness of simulated threats against forces and better, faster decision making.
