military corps that forms a separate service within the U.S. Dept. of the Navy. The commandant of the Marine Corps is a member of the
Joint Chiefs of Staff. During conflicts, the Corps is charged with conducting all land operations essential to the successful prosecution of a naval campaign (see
marines); during peacetime, its top priority is combat readiness. Famous for its
esprit de corps, the Corps emphasizes physical fitness and intensive training. In 1775, the Continental Congress created two federal battalions of marines to serve as naval
infantry. In 1798, the United States Marine Corps was established and placed under the control of the Secretary of the Navy. Marines have participated in every major war, especially the
Mexican War;
World War I;
World War II; the
Korean War; and the
Vietnam War. They have developed expertise in counterinsurgency and
guerrilla warfare, as well as in
commando operations and
amphibious warfare. Marine units are self-sufficient, with their own
tanks and other armor,
artillery, and
air forces.
