Well, for whatever reason, its a mother's job to raise children.
However, it is situational as well. For instance, if the whole world was attacking us, it might be smart to draft EVERYONE who can carry a gun, adult or not. If we were drafting people to, say, fight in Vietnam like we did, the need wasn't quite as strong so the people we drafted was plenty.
If we can help it, I'd rather not draft women because they are supposed to, to a certain extent protected. Granted, they should ABSOLUTELY be allowed to fight in the armed forces, but in general I'd prefer not to make them. Especially those raising young children.
