Thanks chaps.
I just chopped (razor sawed) everything off the backs of the figures (managed to salvage the pack & radio), added some apoxie sculpt pouches and the bergens.
Chopped off the extra fore grips on the rifles (added a barrel to one that had come off).
Added the hoods, and closed the gap at the bottom of the shirts to try to look like windproof smocks. Then added the wooly hats to a couple (apoxie sculpt).
