By September 1945, 40 AA Bde HQ reported directly to AA Command and commanded two 'Area AA Maintenance HQs' (4 and 14), and an ordnance depot at Kincardine in Scotland. It was then rejoined in October and November by 128th and 136th HAA Rgts, and by 14th (West Lothian, Royal Scots) LAA Rgt. In April 1946, these regiments were disbanded and replaced in 40 AA Bde by the reformed 3rd and 5th HAA Rgts, which were Regular Army units that had been lost at the fall of Singapore and Hong Kong respectively in 1941–42.
