A severely damaged U.S. Air Force rescue helicopter sits cordoned off within a blast revetment at a Southeast Asia airbase during the Vietnam War. Helicopters of this type, likely a CH-3/HH-3 'Jolly Green Giant,' carried out combat search-and-rescue missions often escorted by A-1 Skyraiders, and losses or damage such as this reflect the high-risk nature of that mission.
