Patch collection
PETERSON AIR FORCE BASE, Colo. – Lt. Col. Rich Operhall shows off a portion of his collection of more than 15,000 patches. Operhall began collecting patches in junior high and says his collection fuels his passion of Air Force history and heritage. Operhall said this passion is not as much about the patches as it is the stories and the people who make the Air Force work day-to-day. (U.S. Air Force photo/Staff Sgt. J. Aaron Breeden)
