Unofficial military/veteran related popular music...know of any?

Any type of music is OK here...I'm not looking for the most obvious National Recognized as in "The National Anthem" as I'm going to call those "We got that already."

But things one can check out on http://www.youtube.com (or whatever other source than you can cite here) and at least hear, if not find a video for?

I'll start with.... "Veteran" by Ignite. =)
