Osan Airmen provide force, equipment sustainment
Master Sgt. Mark Reuss conducts accountability of Airmen present at the base's reception processing unit during an operational readiness exercise in July 2009 at Osan Air Base, South Korea. As new Airmen arrive during exercises or contingencies, they are processed through the RPU, which is where checks are made to make sure they have all basic mobility items. Sergeant Reuss is assigned to the 51st Force Support Squadron. (U.S. Air Force photo/Staff Sgt. Brian Ferguson)
