The U.S. Army’s 1st Information Operations Command is no more. The active-duty unit shut down in May, after 23 years of operations, citing changing needs in the wider force.
The initial closure was announced last year, as part of the Army Force Structure Transformation plan. 1st Information Operations Command, a part of U.S. Army Cyber Command, focused on cyber warfare and psychological operations. In practice, it worked to help protect other units from information attacks from enemy forces, and served as “red teams” in cyber attack simulations.
