I saw the GR4's plenty of times, usually when they were stuck on the runway after breaking down
Seriously though, what CGS meant to say was that it is easier to redeploy a frigate stuck in the med on patrol to cover Lebanon than it is to provide a deployed force.
Of course if one wanted to be a stirrer you could have the debate held in my (purple) office today. Along the lines of RAF has 4 F3's down South, 6 Harriers in the Stan and * (number not known but not high) in Qatar. Why exactly do we need upwards of 250 Tornados and 80 harriers again?
