• DETACHMENTS: The "Security Squadrons" and Detachments were responsible for electronic communications security. The SP's assigned to Security Squadrons provided physical security at such sites and locations. The same was true for all radar sites, etceteras. Also, sometime after the 14th left Nha Trang the SP's at Nha Trang became "DET-1 483d SPS". It may be impossible to ever list all the SS and SPS's we were assigned to... the only thing we can do and say--SP's were attached to various units to provide security for USAF personnel and resources.
