The SADF carried out mostly reconnaissance operations inside Angola, although its forces in South West Africa could fire and manoeuvre across the border in self-defence if attacked from the Angolan side. Once they reached the Cutline, a reaction force sought permission either to enter Angola or abort the pursuit. South Africa also set up a specialist unit, 32 Battalion, which concerned itself with reconnoitring infiltration routes from Angola. 32 Battalion regularly sent teams recruited from ex-FNLA militants and led by white South African personnel into an authorised zone up to fifty kilometres deep in Angola; it could also dispatch platoon-sized reaction forces of similar composition to attack vulnerable PLAN targets. As their operations had to be clandestine and covert, with no link to South African forces, 32 Battalion teams wore FAPLA or PLAN uniforms and carried Soviet weapons.
