What branch does the Chairman of the Joint Chiefs of Staff belong?

Answer 1

The current Chairman of the Joint Chiefs of Staff is Navy. That position is not part of any branch. That is the highest position in the military that reports directly to the President as part of his Cabinet. The Chairman of the JCS is not in the Cabinet! He reports to the Secretary of Defense, who is a Cabinet member. The real answer to the question is the Chairman of the JCS slot rotates among the services. There's also a rotating Vice Chairman slot, which goes to an officer from a different branch.

Answer 2

The Chairman of the Joint Chiefs of Staff is a four-star general or admiral in the United States military. They can be from any branch of the military - Army, Navy, Air Force, or Marines. However, historically, the position has usually been filled by an Army or Marine Corps general.
