An RAC troop is pretty much a multiple anyway. We re orbatted to Pl strength in each troop, then split down to multiples for the tour. Very good for the RAC to get the opportunity to carry out this role IMHO.
SCOTS DG did a good job, despite certain elements of their parent CF trying to make us pretty unwelcome! QRH have taken over at CF rather than SU level and I suspect they will do a cracking job. The RDG being poor at the task does not surprise me that much to be quite honest.
