In a military navy, a rate or rating, and sometimes known as a bluejacket in the United States, is a junior enlisted sailor who is below the military rank of warrant officer. They are not a commissioned officer. Depending on the country and navy that uses it, the exact term and the range of ranks that it refers to may vary.
In the Royal Navy (RN) and other navies in the Commonwealth, rate and rating are interchangeably used to refer to an enlisted sailor who is ranked below warrant officers and commissioned officers, but may include petty officers and chief petty officers. Specifically, rate is the term used to describe generically all members of all ranks below a warrant officer; whereas rating is part of the official name of individual specific ranks, such as Able Rating and Leading Rating.
The term comes from the general nautical usage of 'rating', to refer to a seaman's class or grade as recorded in the ship's books. [1] The system of conferring authority on sailors in the Royal Navy evolved through the recognition of competence: landsman, ordinary seaman, able seaman, through to the appointment of authority as a petty officer.
The general structure for ratings in the Royal Navy now used breaks down into four major groupings: [2]
| NATO Code | OR-9 | OR-8 | OR-7 | OR-6 | OR-5 | OR-4 | OR-2 |
|---|---|---|---|---|---|---|---|
 United Kingdom Rank Insignia (View) |  |  |  |  |  |  | |
| Rank Title: | Warrant Officer 1 | Warrant Officer 2 | Chief Petty Officer | Petty Officer | Leading Rating | Able Rating | |
| Abbreviation: | WO1 | WO2 [nb 1] | CPO | PO | LH | AB | |
In the United States Navy (USN), the term bluejacket is used instead to refer to enlisted sailors that rank below a chief petty officer. [3] 'Bluejacket' derives itself from an item of clothing that was worn by junior enlisted sailors before 1886. [4] It was used especially when the sailors were deployed ashore as infantry. [5]
In the United States Navy and United States Coast Guard, the term rate refers to an enlisted member's pay grade (i.e. relative seniority or rank), while rating refers to occupational field. In the U.S. Navy and Coast Guard, an enlisted sailor is most commonly addressed, both verbally and in correspondence, by a combination of their rate and rating rather than by rate alone, unlike in other branches of the armed forces. For example, a sailor whose rate is 'Petty Officer 1st Class' (pay grade E-6) and whose rating is 'boatswain's mate' would be addressed as 'Boatswain's Mate 1st Class' (abbreviated BM1). However, it is also correct to address sailors in pay grades E-4 through E-6 simply as 'petty officer' (e.g. 'Petty Officer Jane Smith') and pay grades E-7, E-8, and E-9 are addressed as 'Chief', 'Senior Chief', or 'Master Chief' respectively. Pay grades E-3 and below do not have a rating, and are sometimes referred to as 'non-rates', and simply addressed as 'Seaman', or by their last name alone; i.e. 'Seaman Jones' or merely 'Jones'.
A non-commissioned officer (NCO) is a military officer who does not hold a commission. Non-commissioned officers usually earn their position of authority by promotion through the enlisted ranks. In contrast, commissioned officers usually enter directly from a military academy, officer training corps (OTC) or reserve officer training corps (ROTC), or officer candidate school (OCS) or officer training school (OTS), after receiving a post-secondary degree.
A chief petty officer (CPO) is a senior non-commissioned officer in many navies and coast guards, usually above petty officer.
Senior Chief Petty Officer(SCPO) is an enlisted rank in the navies of some countries.
Master chief petty officer (MCPO) is an enlisted rank in some navies. It is the ninth enlisted rank in the United States Navy and United States Coast Guard, just above Senior Chief Petty Officer (SCPO). Master chief petty officers are addressed as "Master Chief " in colloquial contexts. They constitute the top 1.25% of the enlisted members of the maritime forces.
A petty officer (PO) is a non-commissioned officer in many navies. In many nations, they are typically equal to a sergeant in comparison to other military branches. Often they may be superior to a seaman, and subordinate to more senior non-commissioned officers, such as a chief petty officers.
Seaman is a military rank used in many navies around the world. It is considered a junior enlisted rank and, depending on the navy, it may be a single rank on its own or a name shared by several similarly junior ranks.
A Petty officer third class is a non-commissioned officer in some navies and coast guards.
Petty officer second class (PO2) is a rank found in some navies and maritime organizations.
Petty officer first class (PO1) is a rank found in some navies and maritime organizations.
Leading seaman is a junior non-commissioned rank or rate in navies, particularly those of the Commonwealth. When it is used by NATO nations, leading seaman has the rank code of OR-4. It is often equivalent to the army and air force rank of corporal and some navies use corporal rather than leading seaman.
This is a list of Royal Navy ratings rank insignia.
The United States Navy occupational rating of boatswain's mate is a designation given by the Bureau of Naval Personnel (BUPERS) to enlisted members who were rated or "striking" for the rating as a deck seaman. The colloquial form of address for a boatswain's mate is "Boats".
Master's mate is an obsolete rating which was used by the Royal Navy, United States Navy and merchant services in both countries for a senior petty officer who assisted the master. Master's mates evolved into the modern rank of sub-lieutenant in the Royal Navy, while in the merchant service they evolved into the numbered mates or officers.
The Kriegsmarine was the navy of Nazi Germany prior to and during World War II. Kriegsmarine uniform design followed that of the preexisting Reichsmarine, itself based on that of the First World War Kaiserliche Marine. Kriegsmarine styles of uniform and insignia had many features in common with those of other European navies, all derived from the British Royal Navy of the 19th century, such as officers' frock coats, sleeve braid, and the "sailor suit" uniform for enlisted personnel and petty officers.
The History of the United States Navy ratings spans more than 200 years of U.S. history from the United Colonies of the 1775 era to the current age of the 21st century United States Navy. Navy ratings in America were first created in 1775, during the American Revolutionary War, for use by the Continental Navy. After securing independence, the fledgling United States was without an operational Navy for nearly a decade. In 1797, the first three frigates of the United States were formally launched, bringing about new regulations concerning enlisted seaman ratings
The United States Navy has nearly 500,000 personnel, approximately a quarter of whom are in ready reserve. Of those on active duty, more than eighty percent are enlisted sailors, and around fifteen percent are commissioned officers; the rest are midshipmen of the United States Naval Academy and midshipmen of the Naval Reserve Officer Training Corps at over 180 universities around the country and officer candidates at the navy's Officer Candidate School.
Chief Petty Officer (CPO) is the seventh enlisted rank in the United States Navy and U.S. Coast Guard, is above Petty Officer First Class and below Senior Chief Petty Officer. The term "rating" is used to identify enlisted job specialties. In this way, enlisted personnel are segregated into three segments containing different enlisted ranks. Furthermore, rates are broken down into three levels: non-rated members without a designated occupation. Advancement to E-4 and above is dependent on graduating from a specialty school that define what the enlisted is rated for. Petty officers and chief petty officers are part of the rated force and considered extremely knowledgeable about their particular rating. Examples include Culinary Services Chief and Aviation Maintenance Chief. The Chief Petty Officer is the rank. Gunners Mate is a rating. E7 is a pay grade. The term rating is used to identify the career field of a chief petty officer. For example, the title of a chief petty officer in the Master-at-Arms rating would be spoken or spelled out as Chief Master-at-Arms. The title would be abbreviated MAC. The grade of chief petty officer was established on 1 April 1893 in the United States Navy. The United States Congress first authorized the Coast Guard to use the promotion to Chief Petty Officer on 18 May 1920. Chief petty officer is also the final cadet grade in the United States Naval Sea Cadet Corps.
