I have only made mention of OV-10 & A-10 as 'lo' and 'hi' solutions respectively, nor have I necessarily suggested they be used in concert (although it strikes me that this wouldn't be a bad thing), merely that they,IMHO, represent an 'ideal' solution at either end of the scale.
Typerated mentioned many differing types, both fixed wing and rotary, in his post - to which I then alluded in having played a role in the story of the A-10. Either in the sense of 'learning from' (A-4, A-1, F-5), offering a 'different' route (rotary, mainly - although he fails to mention AH-56, which is kind of where the A-10 tale begins), 'we can do that' (A-7) and 'let's replace it with this' (F-16 - and sundry, other types).
