6931st Security Group

The 6931st Security Group was a United States Air Force unit activated in 1970 at Iraklion Air Station, Crete, Greece. As part of the USAF Security Service (later Electronic Security Command), its primary mission was signals intelligence (SIGINT) and electronic surveillance during the Cold War, monitoring Soviet and Warsaw Pact communications in the Mediterranean and Eastern Europe. The group played a critical role in collecting, analyzing, and disseminating intelligence to support U.S. and NATO operations in the region. The unit was inactivated in 1993 following the end of the Cold War and the closure of Iraklion Air Station.
