In 2005 a Base Realignment and Closure (BRAC) law was passed by Congress. One of BRAC's requirements was the relocation of the United States Army Ordnance Center and School headquarters, the Ordnance Mechanical Maintenance School, the United States Army Ordnance Munitions and Electronic Maintenance School, and the Ordnance Museum to Fort Lee by the end 2011. The transfer of artifacts from Aberdeen to Fort Lee began in August 2009, with the former museum now designated the U.S. Army Ordnance Training and Heritage Center at Fort Lee.
