MR LE ROUX
I saw it like this:  The Ystergarde was a specialist unit of the AWB and they would have, or the operations that needed more experience, they would then execute them.  They would not take part in the normal operations which for example the Wen Kommando would take part in so that is where I said or thought if they wanted bombs to be planted, this is probably part of the process of the broader plan of the AWB.
