Could somebody explain a couple of things to a simpleton such as myself: 1. Why can't RAF Rapier do the same things as Army Rapier i.e. deploy self sufficiently, protect a manoeouvre arm etc. 2. With such a small number of systems why doesn't the RAF give up its airfield defence task to the Army(and its systems). Surely this seems to be a more efficient way of doing things, because the Army can take on both roles? Any Cloud Punchers like to comment?
