By the end of 1944, 21st Army Group was suffering a severe manpower shortage, particularly among the infantry. At the same time the German "Luftwaffe" was suffering from such shortages of pilots, aircraft and fuel that serious aerial attacks on the United Kingdom could be discounted. In January 1945 the War Office began to reorganise surplus AA and coastal artillery regiments in the UK into infantry battalions, primarily for line of communication and occupation duties in North West Europe, thereby releasing trained infantry for frontline service. A number of AA Brigade HQs in 2 AA Group were also converted: on 22 January 1945, HQ 38 AA Bde was converted into 304th Infantry Brigade under Brigadier C.A.H. Chadwick with the following units under command:  After infantry training, the brigade went to Norway in June 1945 to help oversee the surrender of the German occupying forces there. When the TA was reformed in 1947, 38 AA Bde was renumbered 64 AA Brigade, with the following order of battle:  When AA Command was disbanded in March 1955 the brigade was placed into suspended animation on 31 October, and formally disbanded at the end of 1957.
