GreenKnight121,
Posts like your last one are why I love visiting PPRuNe - I learn something new every day. Had no idea that the G91 ever appeared in US colours; certainly knew nothing of the Army A4 modification.
As for the A4 vs A10 argument - I'm sure that if Douglas had produced a way of getting a GAU-gun, titanium tub and a second donk into the Skyhawk then it would've been considered. Perhaps.
Apart from airborne FAC around Wales/ Mercia during my AAC tour (they always needed less hand-holding than any other jet), my only close-hand working experience of the A10 was during the first Gulf unpleasantness when our unit lurked at a base with a wing of them (you can tell I never did ISS, can't you?). Symbiotic, with information being shared during mission debriefs of benefit to each party. Much impressed by their LTC coming back after being bracketed by 57mm; 357 holes in the airframe, which was simply speed-taped and flown back into deeper Saudi for base repair.
