109th MI Group

The 109th Military Intelligence Group was constituted in the United States Army on 1 March 1966, during the height of the Vietnam War. Its primary mission was to provide counterintelligence and security support to U.S. Army forces, with a focus on safeguarding sensitive information and operations. The unit was stationed at Fort Devens, Massachusetts, and played a key role in intelligence operations within the continental United States. The 109th MI Group was inactivated on 21 January 1973 as part of a broader postwar reorganization of Army intelligence assets.
