South Africa Defence Force Signals
The South African Defence Force (SADF) comprised the South African armed forces 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. The SADF was established by the Defence Act No. 44 of 1957. The SADF, in turn, was superseded by the South African National Defence Force in 1994.
