JEFFREY THAMSANQA RADEBE
There was a special training that many people who were in Umkhonto weSizwe  used to undergo, which we used to call MCW, Military Combat Work.
	It was basically training in secrecy, how to set up underground structures, how to communicate such that you make sure that the people that are involved in that operation, one section of the operation, does not know what the other is doing, so that we protect the identity of people who are involved in that operation.
	There has to be cut off in terms of contact with other people.  If one has to take this type of operation, even though I was the political leader responsible and accountable for these Self Defence Units, but I would not know precisely what the person in charge, will be doing in terms of the fulfilment of those tasks.  
	It was what one may call, you were to know on a need to know basis and there was a principle that we used to say that ask no questions, and you will be told no lies, which is a reflection of this elaborate system of cut off.
