(TS//SI) The chart does not include the
numerous miscellaneous and temporary detachments,
or DjF stations belonging to major units
or sites unless that detachment or site was the
only one stationed in South Vietnam. Many of the
"dets" were short-lived, often formed to support
ongoing MACV operations or forward deployments
of combat operational or maneuver units.
These detachments usually were designated by a
letter suffix attached to the higher echelon SIG­
INT address, such as "USM-633J," which was a
detachment of the 372d Radio Research
Company, USM-633, supporting the United
