In addition, the Army was reducing its size very rapidly after the end of hostilities; the tank destroyer branch cost the equivalent of three or four full divisions, a definite luxury for a non-essential service. The 1945 General Board report "Study of Organization, Equipment, and Tactical Employment of Tank Destroyer Units" led to the disbandment of Tank Destroyer Battalions, and on 10 November 1945, the Tank Destroyer Center was closed, effectively ending the long-term prospects of the force. The last battalion was de-activated in 1946.
