The 321st Civil Affairs Brigade is a unit of the US Army Reserve as a part of the 350th Civil Affairs Command.[1] The unit was originally created in 1945 in the Army of the United States as the HHD 101st Military Government Group at the Presidio of Monterey, Calif. It was inactive from 1949-1955 when it was redesignated the 321st Military Government Group in Albuquerque, NM. It would be redesignated again twice before 1963 when it was in San Antonio, Texas as the 321st Civil Affairs Group. It would become a Brigade in 1992.[2]
In 1995-1997, subordinate units of the brigade would serve in Bosnia. In 2003-2005, subordinate units would again be federalized for the Global War on Terror.
