112th Military Intelligence Group

The 112th Military Intelligence Group was originally constituted on 15 February 1966 and activated at Fort Sam Houston, Texas. During the Vietnam War era, the unit was responsible for conducting counterintelligence operations and domestic surveillance, particularly focused on identifying potential subversive activities within the military. The group played a significant role in monitoring antiwar protests and maintaining internal security on U.S. Army installations. It was inactivated on 30 January 1974 as part of a broader reorganization of military intelligence assets following public scrutiny of domestic intelligence activities.
