The 300th was redesignated as the 300th Transportation Corps Service Group on 2 December 1946 and allotted to the Organized Reserves. On 12 December 1946 the unit was activated in Baltimore, Maryland. During that timeframe, the Organized Reserves became the Army Reserve on 9 July 1952.

An activation ceremony was held on 19 April 2008 in Grand Prairie at the Armed Forces Reserve Complex.
