The Seventh Army headquarters remained in Heidelberg until its inactivation on 31 March 1946. The headquarters of the U.S. Third Army then moved from Bad Tölz to Großdeutschland-Kaserne on 2 April 1946. In the meantime the Third Army had activated a new organization on 15 February 1946 called the U.S. Constabulary. The Constabulary was basically a police force with the mission of maintaining law and order in the U.S. Zone of occupied Germany. On February 15, 1947, the Constabulary headquarters moved from Bamberg to Großdeutschland-Kaserne and the Third Army headquarters was inactivated on March 15, 1947.
