The South African National Defence Force's rank system is largely based on the British system, with the Air Force sharing the Army rank titles. Rank titles changed over time as did the insignia.

The South African National Defence Force (SANDF) comprises the armed forces of South Africa. The commander of the SANDF is appointed by the President of South Africa from one of the armed services. They are in turn accountable to the Minister of Defence and Military Veterans of the Defence Department.
