joint chiefs of staff

The Joint Chiefs of Staff is comprised of the most senior uniformed leaders within the Department of Defense. It 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 and consists of a Chairman, a Vice Chairman, the Chiefs of the Army, Marine Corps, Navy, Air Force, Space Force, and the National Guard Bureau. Aside from their Joint Chiefs of Staff obligations, each of the individual service chiefs 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.

The Joint Chiefs of Staff have no executive authority to command combatant forces. The issue of executive authority was clearly resolved by the Goldwater-Nichols DoD Reorganization Act of 1986: "The Secretaries of the Military Departments shall assign all forces under their jurisdiction to unified and specified combatant commands to perform missions assigned to those commands..."; the chain of command "runs from the President to the Secretary of Defense; and from the Secretary of Defense to the commander of the combatant command."

The Coast Guard is a branch of the U.S. Armed Forces pursuant to 14 U.S.C. § 101 and operates under the Department of Homeland Security rather than the Department of Defense. An exception can be made if the President transfers it to the Department of the Navy, e.g., in times of war or national emergency.
The Commandant of the Coast Guard is not a de jure member of the JCS but is sometimes regarded as a de facto member, and, as such, entitled to the same supplemental pay as the Joint Chiefs. The Commandant, by invitation, will also occasionally attend meetings of the JCS. Unlike the Joint Chiefs, who are not actually in the military's operational chain of command, the Commandant is both the administrative and the operational commander of the Coast Guard.

SENIOR ENLISTED ADVISOR TO THE CHAIRMAN (SEAC)

The Senior Enlisted Advisor to the Chairman (SEAC) is a separate military position and rank designated as the most-senior enlisted service member by position in the U.S. Armed Forces. The SEAC serves as the primary enlisted advisor to the Chairman of the Joint Chiefs of Staff (CJCS). Appointed by the CJCS, the SEAC provides essential guidance on joint and combined total force integration, enlisted development, force health, and readiness.

The SEAC serves as a direct link between the CJCS and the Joint Force, ensuring perspectives are represented at the highest levels. While the SEAC’s duties vary based on the CJCS’s direction, the role consistently involves traveling across the Department of Defense, observing training and education, and addressing issues impacting active, Guard, Reserve, retired service members, and military families.

1st Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff (SEAC)
October 2005 - April 2008

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

NOTE:  There is a gap between the 1st and 2nd SEACs as a result of a decision made by then-CJCS Admiral Michael Mullen. After consulting with the Senior Enlisted Advisors (SEA) of the service branches, he chose to not appoint a SEAC for his office. Admiral Mullen felt that the service SEAs were best able to serve the needs of their respective branches being among them rather than having one serve on the JCS. The SEAC position was reinstated by Admiral Mullen’s successor, General Martin Dempsey, in 2011.
