No, this isn’t an advert for the Edinburgh Military Tattoo, or any other. It’s a reminder that
Air Force Instruction 36-2903, Dress and Personal Appearance, states "Excessive tattoos and brands will not be exposed or visible while in uniform." Excessive is defined as any tattoo/brands exceeding one-quarter of the exposed body part and those above the collarbone when wearing an open collar uniform. The AFI also outlines the current provisions and prohibitions to include standards governing piercings and body alterations.
