There was no link between the SDU's and special operations at all.  The earliest SDU's came about in about '86, '86, '87 with the violence in Natal, that was very much a community based operation where the communities started organising themselves, occasionally with units on the ground.
	The special operations units were not always in those areas.  If there may have been some that were internal, they would have assisted the local SDU's but by and large the units didn't necessarily reveal, except to the people that supported them, that they were in fact MK combatants etc. 	So there was no direct link between the SDU's and the special operations unit.
