Interesting responses. I always viewed the military's uniform as something that was the same for everyone - no exceptions. Not knocking the guy's religion at all, I don't care what religion we are talking about here, I just value the uniform more than someone's religious expression while on duty. Not to mention the potential safety issues that can come along with these non-standard appearances and clothing.

So with the logic I have seen from above, everyone is fine with a muslim woman wearing a full burka while showing up for formation in the morning. I suspect not, but my point is as soon as you allow this guy to do his own thing, where does the line get drawn?
