What does YN represent in the USCG rating system?

In the USCG rating system, YN stands for Yeoman. Yeomen are responsible for a variety of administrative duties within the Coast Guard, which can include handling personnel records, maintaining legal documents, and managing correspondence. This rating plays a vital role in ensuring that the administrative functions of the service run smoothly and efficiently.

The other choices represent different specialties within the Coast Guard: Gunner's Mate pertains to weaponry and ordnance management; Health Services Technician refers to medical and health services; and Maritime Law Enforcement Specialist focuses on law enforcement operations related to maritime activities. Each of these roles has distinct responsibilities that differ significantly from those of a Yeoman.
