558th. USAAG Elevsis, Greece

The 558th U.S. Army Artillery Group (USAAG) was a United States Army unit stationed in Elevsis, Greece during the Cold War. Established as part of NATO commitments, the 558th USAAG was responsible for the custody and control of U.S. nuclear warheads assigned to Greek missile units, ensuring their security and readiness. The unit played a crucial role in maintaining deterrence and supporting allied defense strategies in the Eastern Mediterranean region. The 558th USAAG was deactivated following the reduction of U.S. military presence in Greece and changes in NATO’s nuclear posture during the late 1980s.
