The United States Marine Corps, also referred to as the United States Marines or simply the Marines, is the naval infantry service branch of the United States Armed Forces. The service is responsible for conducting expeditionary and amphibious warfare through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is a part of the United States Department of Defense and is one of the six armed forces of the United States and one of the eight uniformed services of the United States. The Marine Corps has legally been part of the United States Department of the Navy since 30 June 1834, along with its sister service, the United States Navy, though it has been under the de facto direction of the Navy Department since its establishment. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are embedded in Navy carrier air wings and operate from aircraft carriers.
