A weathered building bears the identification placard 'DET. 3, 56th SP.OPS.WG.' — Detachment 3 of the 56th Special Operations Wing, the USAF organization most closely tied to the A-1 Skyraider 'Sandy' rescue escort mission during the Vietnam War. Sandbag revetments stacked against the structure reflect the constant threat of rocket and mortar attack faced at forward Southeast Asian air bases. This image is drawn from the personal Vietnam-era photo collection of veteran Bob Karre. Project: 218896
