The thing is, if you are going for realism, then women shouldn't even be out on the battlefield fighting to the equal ability of men in the first place. Hell, they should barely be able to move (for very long anyway) in the heaviest armor, which would require a level of strength and constitution in real life.
As far as I'm concerned, if you can suspend disbelief for that, you can suspend disbelief for skimpy female armors. They are both unrealistic IMO. The most realistic would be to prevent women from wearing heavy armor, or even doing any hand to hand combat, but games will pretty much always portray women as equal to men in all facets in games these days to be politically correct.
I'm happy enough to suspend my disbelief with that, though I never play as a female, so I don't have to as much.
