The Turco-Egyptian ranks were the military ranks used by the Kingdom of Egypt from 1922 until the 1958. The names are Turco-Egyptian (i.e. derived from Ottoman Turkish and Arabic), and are derived at least in part from the preexisting military structure developed out of the reforms of Muhammad Ali Pasha; however, the design of the rank insignia was completely British. High ranks were only given to British officers where the Egypt was a client state of the UK. The rank of Sirdar was given to the British Commander-in-Chief of the Egyptian Army.
