Exercise Beverly Herd 17-2
U.S. Air force Staff Sgt. Matthew Mayo and Tech. Sgt. Christopher Leslie, 51st Aircraft Maintenance Squadron weapons load crew members, load ammunition onto an A-10 Thunderbolt during Exercise Beverly Herd 17-2 at Osan Air Base, Republic of Korea, May 5, 2017. The no-notice exercise challenged the tradition of planning exercises weeks or months in advance, allowing wing leadership a view of how personnel would react in a real-world situation.
