If they can pass the same training, why not? It's not like someone being mortared and shot at is going to "take advantage" of a bunker mate who's armed with a rifle, knife, and bayonet (or more).

The problem that is going to be faced in the long run is that most women don't see any need for combat unless it's to defend themselves, their children, or others near and dear to them.

Besides, "combat" doesn't mean "infantry." It includes tankers, cannon-cockers, gunship pilors, combat engineers, and others.
