You might want to try the RLC bud.I'm looking to join the navy as a basic chef, I've read the guidelines on tattoos and I do have my hand and my fingers tattooed. I assume there is literally no possibility of me joining the navy in any capacity? I assume even in catering there are no exceptions made.
Why Medical?It's kind of too late to do anything about it now. Personally I would go to medical and see what they say.
If they say it's an issue you could always plead with them that in a collared shirt you can't see it.
Good Luck!
