caption_attribution_description: The formation patch for Anti Aircraft Command, a British Army formation that was responsible for ground based air defence in the UK during WW2.
context_page_description: 163rd (Mixed) Heavy Anti-Aircraft Regiment was an air defence unit of Britain's Royal Artillery formed during World War II. Around two-thirds of its personnel were women from the Auxiliary Territorial Service. The regiment defended London, operating the heaviest guns serving with Anti-Aircraft Command.
context_section_description: 163rd (M) HAA Regiment remained with 48 AA Bde in 1 AA Group after the war had ended. When the RA was reorganised on 1 April 1947, 163rd (M) HAA Rgt was redesignated 101 (M) HAA Regiment in the postwar Regular Army, (taking the number of a pre-war Territorial Army unit in Scotland that had been redesignated 501 HAA Rgt). 350, 505 and 538 Batteries were redesignated 241, 296 and 323 (M) Btys. It was one of only three Mixed regiments in the postwar Regular RA. The regiment formed part of 15 AA Bde – the Regular Army element of the old 48 AA Bde – in 1 AA Group of AA Command. 
  However, the new regiment did not last very long under postwar cuts. It was reduced to a cadre in London on 30 June 1948, 323 Bty was disbanded on 10 October, and RHQ and the other two batteries were placed in suspended animation on 10 November, completing the process by the end of the month.
