Brig. Gen. Thomas Harwood III, mobilization assistant to the commander, 13th Air Force, leads a warrior formation run as part of Jungle Day on Aug. 13, 2010. Thirteenth Air Force has observed Jungle Day in Hawaii since 2007, a tradition that originated when the organization was assigned to Andersen Air Force Base, Guam, because it gives members a chance to have fun and give back to the local community every Friday the 13th.
