Marines, also known as naval infantry, are typically an infantry force that specializes in the support of naval and army operations at sea and on land and air, as well as the execution of their own operations. In many countries, the marines are an integral part of that state's navy. In others, it is a separate organization altogether, such as in the United States, where the Marine Corps falls under the US Department of the Navy, yet it operates independently (and similarly the UK's Royal Marines come under Her Majesty's Naval Service). Marines can also fall under a country's army like the Troupes de marine (French Marines) and Givati Brigade (Israeli Marines).
Historically, tasks undertaken by marines have included: helping maintain discipline and order aboard the ship (reflecting the pressednature of the ships' company and the risk of mutiny), the boarding of vessels during combat or capture of prize ships, and providing manpower for raiding ashore in support of the naval objectives.
