The People's Liberation Army of Namibia (PLAN) was the military wing of the South West Africa People's Organisation (SWAPO). It fought against the South African Defence Force (SADF) and South West Africa Territorial Force (SWATF) during the South African Border War. Throughout its history, PLAN had both irregular insurgent and semi-conventional units, as well as an extensive recruitment network in rural South West Africa (Namibia). During the war most of its domestic activities consisted of mine warfare and acts of sabotage. PLAN initially lacked any standing units, and the bulk of operations were carried out by political exiles who spent cyclical periods residing in refugee camps in neighbouring states before launching raids inside South West Africa itself. By the end of the war, PLAN had 32,000 militants under arms, including three battalions of semi-conventional troops equipped with heavy weapons.
PLAN launched its largest and final offensive in late April and early May 1989. Thereafter, it ceased operations due to the ongoing peace process in South West Africa and withdrew to above the 16th parallel south. The bulk of PLAN's forces were disarmed and demobilized on its Angolan camps in late 1989 by the United Nations Transitional Assistance Group (UNTAG) and repatriated to South West Africa. A small number remained in reserve until after Namibian independence, when they were also repatriated. The last PLAN troops and equipment were returned to Namibia in mid-1990 for integration with the new Namibian Defence Force (NDF).
