The South West Africa Territorial Force (SWATF) was an auxiliary arm of the South African Defence Force (SADF) and comprised the armed forces of South West Africa from 1977 to 1989. It emerged as a product of South Africa's political control of the territory which was granted to the former as a League of Nations mandate following World War I.

The South African Defence Force (SADF) comprised the armed forces of South Africa from 1957 until 1994. Shortly before the state reconstituted itself as a republic in 1961, the former Union Defence Force was officially succeeded by the SADF, which was established by the Defence Act of 1957. The SADF, in turn, was superseded by the South African National Defence Force in 1994.
