What You Need to Know About Navy Enlisted Ratings
A Look at Some of the Many Navy Ratings and Their Duties
The Navy calls their enlisted jobs "ratings." Similar ratings are placed into various "communities." For example, ratings that are administrative in nature, are placed in the Administration Community. Ratings that deal with aircraft are placed in the Aviation Community. The Navy Ratings are what other services call Military Occupational Specialties (MOS).
Here's an overview of the Navy job communities and some of the ratings contained within each.
Navy Administration Ratings
The Administration Community is the engine behind the machine of the Navy. Without the specialties of the Admin Community, the Navy would not function the way it does today. Here are a few of the jobs in this rating:
LN - Legalmen (Paralegals) provide legal assistance to fellow sailors in a variety of areas, and prepare records for such proceedings as courts-martial and courts of inquiry, and assist personnel in filing claims, and conducting their investigations.
MC - Mass Communications Specialists are the public relations representatives of the Navy. They write, edit and produce news articles, shoot and edit video, layout and design content online and in print, manage and conduct interviews, and act as public affairs offers
NC - Navy Counselor is a position not open to entry-level enlisted personnel since it requires a thorough understanding of the Navy and how it works. In this rating, among other duties, sailors will interview personnel, prepare and deliver talks, establish and maintain liaison with local media and recruit civilian personnel into the Navy.
PS - Personnel Specialists are like the human resources coordinators for the Navy, providing enlisted personnel with information and counseling about Navy occupations, education and job training, requirements for promotion, and rights and benefits.
YN - Yeoman (Administration) are responsible for a variety of personnel administration tasks, such as maintaining records and official publications, and performing administrative functions for legal proceedings, such as preparing briefs and other documentation.
Navy's Aviation Community
It takes many specialties to make the Aviation Community in the Navy operate smoothly. These ratings cover a wide variety of responsibilities and include aviation mechanics, supply and logistics and air traffic control.
AC - Air Traffic Controllers, like their civilian counterparts, are responsible for directing and controlling the movement of Navy aircraft and instruct pilots via radio communications.
AD - Aviation Machinist's Mates are aircraft mechanics, who perform necessary maintenance, repairs and updates to Navy aircraft.
AE - Aviation Electrician's Mates have tech and electronics expertise and provide repairs and updates to aircraft as well as performing in-flight duties such as operating radar and weapons systems.
AG - Trained in meteorology and oceanography, an Aerographer's Mate (Weather and Oceanography) measure and monitor conditions such as air pressure, humidity and wind speed, and then distribute the information to aircraft, ships and shore facilities.
AO - Aviation Ordnancemen handle and service weapons and ammunition carried on Navy aircraft.
AT - Aviation Electronics Technicians repair and maintain navigation, infrared detection, radar and other complex electronics systems.
Navy Cryptology Ratings (Information Warfare)
These sailors are responsible for receiving, decoding, and analyzing intelligence from foreign nations electronic communications (radio, internet, written, spoken, email and other varieties). Most of the CT ratings are Cryptologic Technicians, with specializations for interpretation, maintenance, networks (maintaining and monitoring the Navy's tech infrastructure), collection and technical.
CTI - Cryptologic Technician - Interpretive
CTM - Cryptologic Technician - Maintenance
CTN - Cryptologic Technician - Networks
CTR - Cryptologic Technician - Collection
CTT - Cryptologic Technician - Technical
IT - Information System Technicians have duties similar to a civilian IT person, operating and maintaining the Navy's satellite telecommunications systems, mainframe computers, local and wide area networks and micro-computer systems.
Navy Intelligence Ratings
The Office of Naval Intelligence is responsible for the collection, analysis and production of scientific, technical, geopolitical, military and maritime intelligence. The Intelligence Community is made up of more than 3,000 military, civilian, reservists and contractor personnel at locations around the world.
This rating includes IS - Intelligence Specialists, who analyze intelligence data, prepare and present intelligence briefings, use maps and charts to produce imagery data and maintain intelligence databases.
Naval Medical and Dental Personnel
The Medical and Dental Communities of the Navy are part of the big medical care machine known as Navy Bureau of Medicine. All the specialties of the medical and dental communities branch off from the Hospital Corpsman rating. You can pursue dental, neurology, cardiology, surgical, combat or special operations medics to name a few specialties available to the Navy Hospital Corpsman (HM).
Nuclear Ratings in the Navy
Ratings in the nuclear field are highly competitive. Applicants need to be well-qualified in math and science since they'll basically be operating nuclear reactors. The submarine force and aircraft carriers run solely on nuclear power and propulsion.
There are three ratings in the Nuclear Field (NF): Machinist’s Mate (MM), Electrician’s Mate (EM), and Electronics Technician (ET). The rating in which an NF candidate is trained is determined at boot camp.
Nuclear-trained MMs, EMs, and ETs perform duties in nuclear propulsion plants operating reactor control, propulsion and power generation systems. The NF will work closely with specialists in the nuclear, technology, and engineering fields.
Navy Builders: The SEABEE Community
In addition to being the builders (the name SEABEE comes from the abbreviation "CB" for "Construction Brigade) of the Navy, construction workers and engineers are trained in combat tactics, maneuvering and defense of their positions.
BU - Builders work as carpenters, plasterers, roofers, concrete finishers, masons, painters, bricklayers and cabinet makers.
CE - Construction Electricians build, maintain and operate power production facilities and electrical distribution systems at Navy installations.
CM - Construction Mechanics repair and maintain a variety of heavy construction and automotive equipment including buses, dump trucks, bulldozers and tactical vehicles.
EA - Engineering Aides are like the foremen of the Navy, conducting land surveys, preparing maps and sketches for construction sites, and estimating costs for building projects.
Navy Security (Military Police)
Military Police and the Naval Master at Arms rates keep the bases and forward operating bases safe from harm by setting up security procedures, controlling access, enforcing existing laws, and deploying defensive tactics when needed.
Duties of the MA - Master at Arms range from conducting security patrols and law enforcement operations to operating brigs and providing protection for high-ranking dignitaries and government officials.
