The ‘Self Defence Units’ (SDUs) were basically an under 18 terrorist division of the ANC’s armed military wing MK. These were youths trained to intimidate and keep the allocated blocks in black residential areas in line with the ANC’s demands. These groups carried out attacks on police and rival black political opponents. https://youtu.be/VCIkPmcN5Po?si=jo30InLOIIaYNUVy
