It was constituted in 1948, partially organized from existing units in 1949, and inactivated in 1950.
The 1st Battalion was redesignated from the 320th Mechanized Cavalry Reconnaissance Squadron, constituted on 21 April 1944 as the 128th Cavalry Reconnaissance Squadron, Mechanized, and activated on 1 May at Fort Riley.
[3][4] The 1st Battalion was inactivated on 28 November 1950 at Cleveland, and the 320th ACR was disbanded on 10 March 1952.
The 320th ACR did not inherit the lineage of the prewar 320th Cavalry Regiment, and was not authorized a coat of arms or distinctive unit insignia.
