The Chief of Defence Force (CDF; ) of Singapore is the head of the Singapore Armed Forces (SAF), who holds the rank of three-star general or admiral. The position was created in 1974 as the Chief of General Staff with the appointment of Winston Choo, and re-titled to its current name in May 1990. Prior to the appointment of Choo as Chief of General Staff, the Ministry of Defence (and before that the Ministry of Interior and Defence) was in charge of the Singapore Armed Forces. Before the position was created, the head of Singapore's army—which at that time made up the military—held the position of director, general staff.
