6th Anti-Aircraft Brigade was an air defence formation of the British Army formed during the Second World War. It served in the disastrous Norwegian Campaign in 1940 and then defended East Anglia during the Battle of Britain and The Blitz. It was reorganised to take part in the invasion of Normandy, but instead was diverted to defending Southern England against V-1 flying bombs. It was briefly recreated in the postwar Regular Army.

The 7th Battalion of the London Regiment was a volunteer unit of the British Army from 1860 until 1961. Recruited from London working men, it sent volunteers to the Second Boer War, saw extensive service on the Western Front during World War I, and defended the United Kingdom as a searchlight regiment during World War II.
