A young U.S. Air Force enlistee poses in herringbone twill fatigues on the grounds of his duty station, circa the mid-1950s. His single sleeve chevron marks him as a junior airman, likely newly assigned following basic training. Informal portraits like this one, taken by friends or family, form an intimate visual record of everyday military life during the early Cold War era, when millions of young Americans served in the rapidly expanding U.S. Air Force.
