Joint Chiefs of Staff

The Joint Chiefs of Staff (JCS) is a body of senior uniformed leaders in the United States Department of Defense. It is tasked with advising the President of the United States, the Secretary of Defense, and the National Security Council on military matters. The JCS does not possess operational command authority over U.S. military forces; that authority resides with the unified combatant commands, as per the Goldwater–Nichols Act.

Composition

The composition of the Joint Chiefs of Staff is defined by statute and includes:

• Chairman of the Joint Chiefs of Staff: The principal military advisor to the President, the Secretary of Defense, and the National Security Council. The chairman presides over the meetings and coordinates the United States Armed Forces.

• Vice Chairman of the Joint Chiefs of Staff: The second-highest-ranking military officer, assisting the chairman in their duties.

• Chiefs of the military services:

  • Chief of Staff of the United States Army
  • Chief of Naval Operations
  • Commandant of the Marine Corps
  • Chief of Staff of the Air Force
  • Chief of Space Operations
  • Chief of the National Guard Bureau

Each service chief is responsible for ensuring the readiness and capability of their respective branch.

Historical Context

The Joint Chiefs of Staff was formed during World War II to present a unified military strategy and planning effort. It evolved over time, especially after the passage of the National Security Act of 1947, which formalized its advisory role and structure.

Role and Responsibilities

While the Joint Chiefs of Staff does not have direct command over military operations, it plays a critical role in the strategic planning and coordination between different branches of the military. The JCS provides a forum for discussion of national security issues and ensures that military advice is consistent and well-informed.

The Joint Staff, consisting of personnel from each of the six service branches, assists the chairman and vice chairman in their responsibilities. The staff is headed by the Director of the Joint Staff.
