I never understood the US military policy on facial hair. A lot of people in the .mil will say stupid shit like "you cant clear your mask if you have a beard." Hey, I'll tell you what, if I have to use my M40 in combat, all I'm going to do is kiss my ass goodbye, anyway.
Beards are great. They are macho, low maintenance and look intimidating. Win-win. I would of loved to of had the shaved head with the 1 inch beard thing going while deployed. a lot of my fellow NATO soldiers had just that, and they looked like F'ing serial killers. Just the type of look you want line units to have if you ask me.
unfortunately, this article is a joke according to the comments. I do agree that they are beneficial, though.
