Two U.S. Air Force personnel pose informally beside a squadron building during the Vietnam War, with a hand-painted sign identifying the unit commander, 'Lt. Col. J.W. Wold,' and a partial 'SOW' (Special Operations Wing) designation. One man wears standard jungle fatigues while the other is dressed in a flight suit, illustrating the mix of ground support and aircrew personnel who served together at Southeast Asian air bases during this period.
