Base Realignment and Closure (BRAC) is a process by a United States federal government commission to increase United States Department of Defense efficiency by coordinating the realignment and closure of military installations following the end of the Cold War. More than 350 installations have been closed in five BRAC rounds: 1988, 1991, 1993, 1995, and 2005. These five BRAC rounds constitute a combined savings of $12 billion annually.
