Royal Observer Corps
In 1929 the control of the Observer Corps passed from the county police forces to the Air Ministry, although Chief Constables retained responsibility for personnel and recruitment matters. 1 March 1929 saw the establishment of the new "Headquarters of the Observer Corps" at Hillingdon House, RAF Uxbridge in the west of London, and Air Commodore Edward A D Masterman CB CMG CBE AFC RAF (Rtd) was appointed as the first commandant of the Observer Corps. "Air Cdre" Masterman held this appointment until his retirement on 1 March 1936, and was succeeded by Air Commodore Alfred Warrington-Morris CG CMG OBE AFC RAF (Rtd), who would lead the Observer Corps through the critical period during the Second World War which saw the RAF emerge bruised but victorious following the Battle of Britain of 1940.
Yeomen of the Guard
The Queen's Body Guard of the Yeomen of the Guard are a bodyguard of the British Monarch. The oldest British military corps still in existence, it was created by King Henry VII in 1485 at the Battle of Bosworth. As a token of this venerability, the Yeomen still wear red and gold uniforms of Tudor style. There are 60 Yeomen of the Guard (plus six officers), drawn from retired members of the British Army, Royal Marines and Royal Air Force, but traditionally not the Royal Navy. This ban on Royal Navy Personnel was lifted in 2011 and two sailors joined the ranks of the Yeomen of the Guard. However, the role of the Captain of the Queen's Body Guard of the Yeomen of the Guard is a political appointment — the captain is always the government Deputy Chief Whip in the House of Lords.
