its 2005 Base Realignment and Closure Commission Recommendations, DoD recommended to relocate the Third US Army Headquarters from Fort Gillem and Fort McPherson, Georgia, to Shaw AFB as a tenant unit on the base. This was a portion of a larger recommendation that would close Fort Gillem and Fort McPherson. On 1 June 2011, Third Army Headquarters at Shaw, Patton Hall, was dedicated during a ribbon cutting ceremony for their new headquarters. Third Army continued the transfer of its personnel and equipment in order to be fully operational at Shaw AFB by 15 June 2011. An estimated 3,000 people relocated to the Sumter area, including families. This includes approximately 1,200 service members, who will be working out of the $100 million, command and control facility. The new Patton Hall took 22 months to build, has 42 conference rooms, a 200-seat auditorium and can support up to 1,500 personnel.
