Combat Support
From ARRSEpedia
Quite a lot of the Army, actually and, probably, most of its striking power (although that is mostly in the Royal Regiment with a wee bit belonging to the sappers).
Consists of:
- The Royal Artillery and Royal Horse Artillery
- The Royal Engineers
- The Royal Signals
- The Intelligence Corps
Quite often, at the moment, some gunners escape into pseudo combat arm employment as Infantry, and have to carry a bit more weight on their BFT, although this was more common in Iraq, where there were more restrictions on them actually using their colours in the death-dealing mode.
