The way it use to be (I joined in 96), a woman that had brows tattooed on her face technically was in violation! does that make sense? No.
Even if they aren’t extremist or racist, a tattoo on the back of the neck doesn’t exactly show professionalism. It sort of makes the Army look tacky. I’ve seen some pretty fantastic tattoos on soldiers, but none that could be seen while in a Class A. And there is a reason for that: While in uniform you represent America, and you want to represent her well.
