1 Jan 1977: U.S. Army Intelligence and Security Command (INSCOM) was established.
The US Army Intelligence and Security Command (INSCOM) began at Arlington Hall Station in Virginia on 1 January 1977. INSCOM was organized as a result of the Army's Intelligence Organization and Stationing Study (IONS) -- an in-depth look at Army intelligence requirements initiated in 1975. Three main elements were originally combined to form INSCOM in 1977: the US Army Security Agency (USASA); US Army Intelligence Agency (USAINTA); and a number of different intelligence production agencies, most of which had been under the Assistant Chief of Staff for Intelligence (ACSI) for direct control. In its first seven years, INSCOM grew in strength from 10,400 to 15,000 personnel.
