If they want to serve in the military, they should abide by their rules. I'm not religious, but if I wanted to serve in the military and have to swear on a bible, which will take a whole two minutes, then I'll suck it up and deal with it. There's a lot of things you have to do in life that you don't want to; that being one of them. But I don't understand why it's a bible, considering the United States doesn't have an official religion; just a dominant one.
