Chaplains have non-combatant status and do not participate directly in hostilities. In the U.S. they are prohibited from carrying weapons. Chaplains are assisted by Navy enlisted personnel in the Religious Program Specialist (RP) rating, when available. Otherwise, a variety of personnel in the Marine Corps, Navy, and Coast Guard—as applicable—may support unit chaplains. RPs who are combatants also serve as the armed protection for chaplains in combat and other operational environments. Since RPs are enlisted, the Chaplain Corps, while protective of them, does not "own" the rating.
