Marines
Marines, or naval infantry, are typically military forces trained to operate in littoral zones to support naval operations. Historically, tasks undertaken by marines have included helping maintain discipline and order aboard the ship (reflecting the pressed nature of the ship's company and the risk of mutiny), boarding vessels during combat or capture of prize ships, and providing manpower for raiding ashore in support of the naval objectives. In most countries, the marines are integral to that state's navy.[Casson, Lionel]
The term "marine" does not exist in many languages other than English. In French-speaking countries, two terms exist which could be translated as "marine" but do not translate exactly: troupes de marine and fusiliers-marins; similar pseudo-translations exist elsewhere, e.g., fuzileiros navais in Portuguese (lit. 'Naval fusiliers'). The word marine means "navy" in many European languages, such as Dutch, French, German, Italian, and Norwegian.
The Ukrainian Marines was founded in 1993 from a unit of the former Soviet Naval Infantry. It serves as a coastal defense force of the Ukrainian Navy. Also known by its official name, the "Ukrainian Naval Infantry," the sub-branch of the Navy is based in Mykolaiv.[Aroor, S.]
