Heh, you're the second person to ask that. I'd prefer it if you would reskin it to something more normal looking, or at least make it so that they disguised their true nature. I normally wouldn't be bothered by stuff like this but it's hard for me to find a very justified reason for the military to hire someone who appears obviously evil or untrustworthy.
Even if your character was a saint, you have got to admit, it's hard for someone like a shade or a vampire or a drow to just walk up to a military official and say, "Hey I wanna help out in that high profile operation you guys are running. I'm totally legit, honest."
All that said, if you can make a justified reason for why your character is a shade and why they'd get hired for this job, then I'm okay with it. I just put up the rule so that people don't flood the application list with a bunch of weird stuff without a thought on how their character fits in the world.
