I think military service shouldn't be an issue at all. Being a good soldier means not thinking about politics and obeying commands. But it always seems to be a campaign issue so you can't blame either side for trying. And, yeah, it's probably the Demo side trying to make it more of an issue and that's because it's an issue they have a strong advantage in my opinion and obviously the GOP side feels so too because they are grasping at straws here.
