 Brigadier Dudley Wrangel Clarke CB, CBE (27 April 1899 – 7 May 1974) was an officer in the British Army, known as a pioneer of military deception operations during the Second World War. His ideas for combining fictional orders of battle, visual deception and double agents helped define Allied deception strategy during the war, for which he has been referred to as "the greatest British deceiver of WW2". Clarke was also instrumental in the founding of three famous military units, namely the British Commandos, the Special Air Service and the US Rangers.
