Shaving advice please?

I went through AF basic having a 10am shadow. Even though I HAD gotten everything when I shaved, it looked like I hadn't. Just do the best you can and they'll send you back to shave again probably a few times within about 10 minutes the first day or two. You'll tear your face up, and once they see what the deal is, they'll lay off. You may get disciplined down the road but it won't be harsh at all. If you get razor bumps, you can probably get a shaving waiver.
