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.
In the Commonwealth, it is the lowest rank in the navy, while in the United States, it refers to the three lowest ranks of the U.S. Navy and U.S. Coast Guard. The equivalent of the seaman is the matelot in French-speaking countries, and Matrose in German-speaking countries.
The Royal Australian Navy features one Seaman rank.
There are 4 grades of seaman/matelot in the Royal Canadian Navy:
The rank of master seaman is unique because it was created only for the Canadian Navy. It does not follow the British tradition of other Canadian ranks. It corresponds to the rank of master corporal/caporal-chef.
Matelot 2e classe (seaman 2nd class), or apprentice seaman, and matelot breveté (able seaman) are designations of the French Navy. Matelots are colloquially known as "mousses".
There is one grade of seaman in the Hellenic Navy.
In the Indonesian Navy, this rank is referred to as "kelasi". There are three levels of this rank in the Indonesian Navy which are: "seaman recruit" (kelasi dua), "seaman apprentice" (kelasi satu), and "seaman" (kelasi kepala), the rating system thus mirrors the one used in the US Navy.
Seaman rank of the Indonesian Navy
Much Russian military vocabulary was imported, along with military advisers, from Germany in the 16th and 17th centuries. The Russian word for "seaman" or "sailor" (Russian: ; matros) was borrowed from the German "matrose". In Imperial Russia the most junior naval rank was "seaman 2nd class" ( 2-? ; matros vtoroi stati). The 1917 Revolution led to the term "Red Fleet man" (; krasnoflotets) until 1943, when the Soviet Navy reintroduced the term "seaman" (; matros), along with badges of rank. The Russian federation inherited the term in 1991, as did several other former Soviet republics, including Ukraine, Azerbaijan and Belarus, with Bulgaria using the same word and the same Cyrillic orthography. Estonia (Estonian: m?trus) and Latvia (Latvian: m?trozis) use closely related loanwords.
In the Royal Navy the rate is split into two divisions: AB1 and AB2. The AB2 rating is used for those who have not yet completed their professional taskbooks. The rate of ordinary seaman has been discontinued.
Seaman is the third enlisted rank from the bottom in the U.S. Navy and U.S. Coast Guard, ranking above seaman apprentice and below petty officer third class. This naval rank was formerly called "seaman first class". The rank is also used in United States Naval Sea Cadet Corps, a naval-themed uniformed youth program under the sponsorship of the Navy League of the United States.
The actual title for an E-3 in the U.S. Navy varies based on the subset of the Navy or Coast Guard, also known as a group rate, to which the member will ultimately be assigned. Likewise, the color of their group rate mark also depends on that subset of the Navy or Coast Guard in which they are serving and which technical rating they will eventually pursue.
No such stripes for E-1, E-2 or E-3 are authorized to be worn on working uniforms, e.g., navy work uniform, USCG operational dress uniform, coveralls, utility wear, flight suits, hospital and clinic garb, diving suits, etc. However, sailors with the pay grade of E-2 or E-3 are permitted to wear silver-anodized collar devices on their service uniforms.
Some sailors and Coast Guardsmen receive a rating following completion of a military technical training course for that particular rating known as an "A" school. Other sailors and Coast Guardsmen who have completed the requirements to be assigned a rating and have been accepted by the Navy Personnel Command/Bureau of Naval Personnel (USN) or the Coast Guard Personnel Service Center Command (USCG) as holding that rating (a process called "striking") are called "designated strikers", and are referred to by their full rate and rating in formal communications (i.e., machinist's mate fireman (MMFN), as opposed to simply fireman (FN)), though the rating is often left off in informal communications. Those who have not officially been assigned to a rating are officially referred to as "undesignated" or "non-rates." Once selected for a particular rating of their choice they become eligible for advancement in that community.
