United States Marine Corps

The United States Marine Corps (USMC) is a branch of the United States Armed Forces responsible for providing power projection, using the mobility of the United States Navy to, by Congressional mandate, rapidly-deliver combined-arms task forces on land, at sea and in the air. The U.S. Marine Corps is one of the four armed service branches in the U.S. Department of Defense and one of the seven uniformed services of the United States. The current Chairman of the Joint Chiefs of Staff, the highest-ranking military officer in the U.S. armed forces, is a Marine Corps general.

The Marine Corps has been a component of the U.S. Department of the Navy since 1834,working closely with naval forces for training, transportation, and logistics. The USMC operates posts on land and aboard sea-going amphibious warfare ships around the world, and several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the Navy's nuclear-powered aircraft carriers.
