Special Operations Association Reunion (SOAR XXXVIII), Las Vegas, 2014. An elderly Air Force veteran wears a retired-service ball cap lettered PROUDLY SERVED beneath the Air Force coat of arms, together with a Special Operations Association T-shirt. Self-identifying headgear of this kind is a defining feature of modern American veterans' reunions and often the only documentary record of a participant's service. From the personal collection of Don Engebretsen. Project: 219867
