22nd Crash Rescue Boat Squadron
The 22nd Crash Rescue Boat Squadron (22nd CRBS) was a U.S. Air Force combat search and rescue unit formed during the Korean War. While its original task was ocean rescue of downed pilots, its speedy and well-armed boats soon became prime vehicles for inserting spies, espionage agents, and sabotage parties into enemy territory for the 6004th Air Intelligence Service Squadron.
