Is the fast jet the right tool for CAS,or are we relearning the lessons of Vietnam that gave birth to the A-10 and Su-25 in the first place ?- i.e. what's needed is slower, heavily armed and armoured aircraft that can put a lot of things that go bang on target, and loiter until they are needed.
Or the original USMC operational plan for the Harrier - fast turnaround from FOBs so that again lots more things that go bang are put on target?
