Capt. Benjamin Aiken maneuvers a C-17 into refueling position under a KC-135 Sept. 10 during Mobility Guardian, AMC’s largest full-spectrum readiness exercise to date. Hosted by Fairchild AFB, Wash., 46 US aircraft joined aircraft from 29 international partners and more than 4,000 US and international Air Force, Army, Navy, and Marine Corps aviators. The massive exercise emulated the contested, degraded, and operationally limited environments mobility forces can face in combat and emergency conditions.
