I like Storch's suggested setup, but I would make the following alterations. Not because they werent there, but ...... well here goes.
First off (and I know this isnt popular but.....) Allied forces in Italy were transitioning from Spit V to the Spit IX in '43, so the V was still very much in use. I'm not saying enable it, as I think the IX can very well represent both (and they WERE transitioning anyway).
But given that logic, we should cut the P-40s since they were transitioning to the P-51B in '43. At least the P-40B, we could leave the E in.
We should also take out the F4F-4 for the same reason, maybe leaving the FM2 for carrier duty.
I'd also lose the TBM, although for different reasons. Having just the SBD as a dive bomber would balance with the Ju-87. The axis is still hurting in the level bomber matchup, but that cant be avoided due to the lack of planes available.
The axis setup I would leave the same, but instead of capture at 200 troops, make it something do-able like 50. It would still be darn near impossible to milk run the map, but it would make for interesting squad missions to take a base with max hardness and 50 troops needed for capture. I dont know, maybe I've been flying in the MA too much, but I like defending bases. It gives me an added sense of realism for my solo missions. Plus it would give them something to do with those buffs besides use em as gun platforms.
