I'm not sure if they have ditched the rear kidney pouch, it might just be that mine is missing as it seems most on this set is removable. Perhaps there is a detachable kidney pouch?? Yip you are correct the side pouches are removable. There are a few clips on the rear top and bottom which could suggest there is a detachable camel-pack. I might be getting my hands on an official "catalog" for SANDF webbing which apparently shows all the detachable items. Will let you know if i get it. Regarding the braces there is a strap coming from the left and right brace which clips together in the middle - this is in the front, basically on the chest, which would suggest that would stop them from slipping off. Labels wise nothing at all and no place where one could say they have been removed, and it is an unused item.
