The Chief of the Defence Staff (CDS) is the professional head of the British Armed Forces. The post was created in 1956 to reflect the new conceptions of joint operations that had come to the fore in World War II. Prior to the creation of the post, one of the three members of the Chiefs of Staff Committee was appointed chairman. From its creation up until the mid-1990s, the Chief of the Defence Staff was appointed to the highest rank in the branch of the British armed forces to which he belonged (equivalent to a US "five-star" rank) being an Admiral of the Fleet, a Field Marshal or Marshal of the Royal Air Force. However, with the defence cuts, having a such a high rank serving officer was seen as too expensive, and too prestigious for the post-Cold War size of the British Armed Forces. Consequently, since then the Chief of the Defence Staff was not promoted and retained the lower ("four-star") rank of (Admiral, General or Air Chief Marshal). The current Chief of the Defence Staff is Air Chief Marshal Sir Jock Stirrup who succeeded General Sir Michael Walker on 28 April 2006. It is traditional for the holder of the post of CDS to be from a different service from his predecessor (this has only been broken once, when General Guthrie succeeded Field Marshal Inge) and also a different service from his deputy, the Vice-Chief of the Defence Staff (VCDS). The current VCDS is General Sir Timothy Granville-Chapman.
