The Namibian constitution defines the role of the military as "''defending the territory and national interests.''" Namibia formed the Namibian Defence Force (NDF), comprising former enemies in a 23-year bush war: the People's Liberation Army of Namibia (PLAN) and South West African ''Territorial Force'' (SWATF). The British formulated the plan for integrating these forces and began training the NDF, which consists of a small headquarters and five battalions.
