Retreat
Senior Airman Michael Pecher, 319th Operations Support Squadron, folds the flag during the Retreat Ceremony June 10, 2011 on Grand Forks Air Base, N.D. The base will have different Squadrons perform retreat until the Friday before Labor Day. The Retreat Ceremony serves a twofold purpose – it both signals the end of the duty day and serves as a ceremony for paying respect to the flag. (U.S. Air Force photo by Senior Airman Amber Bennett)
