Alright then - a curtain call and some backtracking.
In no way did I mean to denigrate the US Marine Corps for it's professionalism or bravery. I am not a Yank basher and unreservedly apologise if offence was caused.
My point was the USMC are renowned for their physical prowess. They are soldiers in jets and for that reason the British Army holds them as a model for what it thinks the RAF should be like. However, their air power is solely configured for support of it's ground forces and they are often difficult to integrate into the wider air campaign. Many functions are performed for them by the USN and USAF so they can afford to concentrate on what they are good at. With broader responsibilities the RAF should not try to emulate the USMC and should uphold it's own traditions and characteristics, one of which is higher regard for brains than brawn.
Late for body pump now - it'll have to be Pilates instead.
