Marines

Marines, also called naval infantry, are military personnel generally trained to operate on both land and sea, with a particular focus on amphibious warfare. Historically their main tasks have included raiding ashore, often in support of naval objectives, and boarding vessels during ship-to-ship combat or capturing prize ships. Marines also helped keep security, discipline and order aboard ships, given the risk of mutiny among a pressed crew. In modern times they also carry out rapid-response operations, humanitarian aid, disaster relief, special operations and counter-terrorism. In most nations marines are an integral part of the navy, as with the United Kingdom Royal Marines or Mexican Naval Infantry; elsewhere they sit within the land army, as with the French Troupes de marine, or, less commonly, form an independent branch, as with the United States Marine Corps and the Ukrainian Marine Corps.
