HISTORY
621 TCS/SP A bit of history. The 621st TCS lives on at Osan AB Korea as the 621st ACS.  Its patch is a cobra wrapped around a radar antenna. I was commander of Det 1, 621st TCS a Yongmun San (Dragon Mountain) Korea from 1975-1976. Det-1 was the closest radar site to the DMZ on top of a 5000 ft mountain. At some point in time the Air Force changed from TCS to ACS.
