Master Sgt. John Sibula, formerly with 927th Aerospace Ground Equipment at Selfridge Air National Guard Base, Mich., is temporarily assigned to the 459th Aircraft Maintenance Squadron at Andrews Air Force Base, Md. The Defense Base Closure and Realignment commission relocated his home unit from Selfridge ANG Base to MacDill AFB, Fla., so Sergeant Sibula elected to serve at Andrews AFB before he retires from the Air Force Reserve.
