Married 2 kids & 1 on the way. 2 small tattoos on forearm. 10yo C misdemeanor. Can I join the Navy?

You should call a recruiter and tell them that the misdemeanor was for drug paraphemalia this way your upfront about it to the service you would like to join. This way they can tell you the rules on things like that i wouldn't think it should hurt anything cause its a misdemeanor they would know more about it.
