Hal Puthoff worked there with the NSA during his service in the Army or as a civilian.
These units were managed by the Army Intelligence and Security Command (INSCOM), and overseen by the Defense Intelligence Agency (DIA).
These operational units supposedly provided intelligence for actual military operations, first for just the Department of Defense, but later for the entire intelligence community. They complimented research done at SRI, and were supported by a medical unit that monitored the viewers' health. A seperate unit kept track of Soviet research.
The program started under Ed Thompson, and screened applicants for previous paranormal experiences.
