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.
Australia
The Royal Australian Navy features one seaman rank, which is split into two distinct classes. Seaman and seaman* (pronounced "seaman star"), to differentiate between those who have completed their employment training and those who are in training. There is no insignia on a seaman rank slide.
Canada
There are 4 grades of sailor (previously the term "seaman", until it was replaced with "sailor" in August 2020)/matelot in the Royal Canadian Navy:
The rank of master sailor 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.

Russia
Much Russian military vocabulary was imported, along with military advisers, from the Dutch Republic in the 16th and 17th centuries. The Russian word for "seaman" or "sailor" (; matros) was borrowed from the Dutch "matroos". In Imperial Russia the most junior naval rank was "seaman 2nd class" (матрос 2-й статьи; matros vtoroi stati). Estonia () and Latvia () use closely related loanwords.
The 1917 Revolution led to the term "Red Fleet man" (краснофлотец; krasnoflotets) until 1943, when the Soviet Navy reintroduced the term "seaman" (матрос; 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.
United Kingdom
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.

Seamaninsignia
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, such as Medal of Honor recipient James R. Ward. 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 and insignia for an E-3 varies based on the job rating to which the member will ultimately be assigned.
