The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, which advises the president of the United States, the secretary of defense, the Homeland Security Council and the National Security Council on military matters. The composition of the Joint Chiefs of Staff is defined by statute. It consists of a chairman, a vice chairman, the chiefs of the Army, Marine Corps, Navy, Air Force, and Space Force, and the chief of the National Guard Bureau. Each of the individual service chiefs, outside their Joint Chiefs obligations, works directly under the secretaries of their respective military departments, e.g. the secretary of the Army, the secretary of the Navy, and the secretary of the Air Force.
