The SA Army was formed in 1912 as the Union Defence Force. It was given its present name in 1951. The rank system is derived from that of the British Army.
The ranks of General Officers changed in September 2003 when the rank previously called Brigadier became known as Brigadier General.

The private is called a "gunner" in the artillery and anti-aircraft, a "rifleman" in the infantry, a "trooper" in the armoured corps, a "sapper" in the engineers, a "signalman" in the signals corps, and a "scout" in the intelligence corps.

However they would retain the rank of WO1, while wearing unique rank insignia. To distinguish the posting different colour backgrounds were used; for example, red for regimental sergeant major and black for command sergeant major.

In 2008 the warrant officer ranks were expanded to make each substantive rank a formal rank.
The SA Air Force was formed in 1920. Unlike many other Commonwealth air forces, it had an army style rank system. In 2002 the Air Force officer rank insignia structure was changed from one which was shared with the Army to a new pattern based on stripes. The Air Force stated that this was "in order to bring it more in line with international forms of rank". The army-style rank titles were retained. Note: The rank of General is only used when the Chief of the Air Force is also the Chief of the Defence Force which has occurred on occasion in the past. In 2005 the South African Air Force redesigned its insignia completely, while keeping the Army titles.
The SA Navy was originally two separate organisations, namely the South African Division of the Royal Navy Volunteer Reserve (formed in 1913) and the South African Naval Service (formed in 1922 and renamed the "Seaward Defence Force" in 1939). They amalgamated in 1942 to form the SA Naval Forces, which were renamed "SA Navy" in 1951. The rank system is based on that of the (British) Royal Navy.
The ranks of flag officers changed in 1997 when the rank previously called Commodore became known as Rear Admiral (Junior Grade).
