The Navy isn’t the only service to tighten rules on body art.
The Marine Corps uses naval administration messages as guidelines to form some of its own regulations.
The Corps regulations apply to both on- and off-duty Marines, and stipulates that males will not wear earrings and neither sex is permitted “eccentricities,” said spokesman Capt. Jeff Landis, citing a few examples.
When in civilian clothes, “Marines will ensure that their dress and personal appearance are conservative and commensurate with the high standings traditionally associated with the Marine Corps,” the regulation reads.
Tattoos or brands on the neck and head are prohibited and “attaching, affixing, or displaying objects, articles, jewelry or ornamentation to or through their skin, tongue or any other body part” is banned in the Corps.
In general, clothing cannot be used to cover unauthorized tattoos or brands. Removing tattoos will be done at the servicemember’s expense.
Members failing to comply are subject to Article 92 of the Uniform Code of Military Justice, and face the maximum penalty of a dishonorable discharge or dismissal, two years’ confinement, total forfeiture of pay and allowances and a reduction to the lowest pay grade.
