Joint Chiefs of Staff

The Joint Chiefs of Staff (JCS) is a body of senior uniformed leaders in the United States Department of Defense who advise the Secretary of Defense, the Homeland Security Council, the National Security Council and the President of the United States on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of the Chairman of the Joint Chiefs of Staff (CJCS), Vice Chairman of the Joint Chiefs of Staff (VCJCS), and the Military Service Chiefs from the Army, Marine Corps, Navy, Air Force, and the Chief of the National Guard Bureau, all appointed by the President following Senate confirmation. Each of the individual Military Service Chiefs, outside of their Joint Chiefs of Staff obligations, works directly for the Secretary of the Military Department concerned, i.e., Secretary of the Army, Secretary of the Navy, and the Secretary of the Air Force.

Following the Goldwater–Nichols Act in 1986, the Joint Chiefs of Staff do not have operational command authority, neither individually nor collectively, as the chain of command goes from the President to the Secretary of Defense, and from the Secretary of Defense to the Commanders of the Combatant Commands. Goldwater–Nichols also created the office of Vice Chairman, and the Chairman is now designated as the principal military adviser to the Secretary of Defense, the Homeland Security Council, the National Security Council and to the President.

Chief of staff

The title chief of staff identifies the leader of a complex organization, institution, or body of persons and it also may identify a principal staff officer (PSO), who is the coordinator of the supporting staff or a primary aide-de-camp to an important individual, such as a president or a senior military officer.

In general, a chief of staff provides a buffer between a chief executive and that executive's direct-reporting team. The chief of staff generally works behind the scenes to solve problems, mediate disputes, and deal with issues before they are brought to the chief executive. Often chiefs of staff act as a confidante and advisor to the chief executive, acting as a sounding board for ideas. Ultimately the actual duties depend on the actual position and the people involved.

Chiefs of Staff

A Chief of Staff or Chiefs of Staff is defined as the senior officer of any of several services of the armed forces of several nations and may refer to:

Chairman of the Joint Chiefs of Staff

The Chairman of the Joint Chiefs of Staff (CJCS) is the highest-ranking military officer in the United States Armed Forces and is the principal military advisor to the President, the National Security Council, the Homeland Security Council, and the Secretary of Defense. While the Chairman of the Joint Chiefs of Staff outranks all other commissioned officers, he is prohibited by law from having operational command authority over the Armed Forces; however, the Chairman is permitted to assist the President and the Secretary of Defense in exercising their command functions.

The Chairman convenes the meetings and coordinates the efforts of the Joint Chiefs of Staff (JCS), an advisory body within the Department of Defense comprising the Chairman, the Vice Chairman of the Joint Chiefs of Staff, the Chief of Staff of the Army, the Chief of Naval Operations, the Chief of Staff of the Air Force, the Commandant of the Marine Corps, and the Chief of the National Guard Bureau. The post of a statutory and permanent Joint Chiefs of Staff chair was created by the 1949 amendments to the National Security Act of 1947. The 1986 Goldwater-Nichols Act elevated the Chairman from the first among equals to becoming the "principal military advisor" to the President and Secretary of Defense.

Joint

A joint or articulation (or articular surface) is the location at which bones connect. They are constructed to allow movement (except for skull, sacral, sternal, and pelvic bones) and provide mechanical support, and are classified structurally and functionally.

Classification

Joints are mainly classified structurally and functionally. Structural classification is determined by how the bones connect to each other, while functional classification is determined by the degree of movement between the articulating bones. In practice, there is significant overlap between the two types of classifications.

Terms ending in the suffix -sis are singular and refer to just one joint, while -ses is the suffix for pluralization.

An articulate facet is generally seen as a small joint, especially used when speaking of the joints of the ribs.

Structural classification (binding tissue)

Structural classification names and divides joints according to the type of binding tissue that connects the bones to each other. There are three structural classifications of joints:
