Dobbins ARB is the only U.S. military facility left in northern Georgia after the 2005 Base Realignment and Closure Commission (BRAC) recommendations were enacted. The Georgia Air National Guard transferred to Robins AFB in 1996, leaving Air Force Reserve C-130s as the only Air Force flying unit at the base. The 248th Medical Company (Air Ambulance) and elements of the 151st Aviation Regiment of the Army National Guard are also based there. More units relocated to Dobbins ARB as the Georgia Army National Guard took over NAS Atlanta as the latter closed due to BRAC and became a tenant non-flying command known as Navy Operational Support Center Atlanta.
