In the context of SIM EC, I thought the A10C was absolutely fantastic. I've seen them work well in RB air and ground. The AIM-9M's are pretty nice.Back when there was only the A7D, it was pretty decent- but if you're into Ground RB, the A7E gets up to 6 walleyes, and might be worth looking into if you really like the US 10.3/10.7 ground bracket.The Harrier- well.. -personally- I think there are better alternatives, both for air and ground battles. FWIW- until the F-18's, the Harrier was the last plane I have to research in the US air tree, because I didn't really feel that it had more to offer than the others.
