This diagram is provided by the air force. Unauthorized areas include the neck, face, head, tongue, lips, and scalp. They also include the hand, but we’ll get into that in a second. Now, with the head and upper neck area, you’re looking at even the inside of your lips. You are not authorized to have tattoos.
Now, the reason that there’s a little dip in the front portion of the neck into the chest a little bit is because the air force actually has an open collar blues uniform. You will wear it very rarely, but when you do, you still need to fit into the regulations. That is why that area is unauthorized to have tattoos. Now, as far as the hands go, you are allowed to have a single band ring tattoo on one finger, on one hand. It does not matter which hand or finger, but you only get one ring tattoo.
Other unauthorized tattoos include anything that is related to gangs or extremists and supremacist organizations. Also, anything that advocates sexual, racial, ethnic, religious discrimination will not be allowed. Additionally, in the AFI, it states that tattoos, brands or body markings that are grossly offend to modesty, decency, propriety or shocks the moral sense because of its vulgar, filthy or disgusting nature, or its tendency to incite lustful thought will not be allowed. Now, I think we could sum up most of this to pornographic content. You want to read more, you can go to AFI 36 29.
