13 Anti-Aircraft Brigade was formed in June 1941 to provide Anti-Aircraft defence for Chittagong and East Bengal. This area was gradually extended to include Arakan as the allies advanced into Burma (Myanmar). By May 1945 they were also responsible for Ramree Island. 13 Anti-Aircraft Brigade disbanded in September 1945.
