Who is the principal military advisor?

• A. The Chairman of the Joint Chiefs of Staff.
• B. The Secretary of the Navy.
• C. The Chief of Staff of the Army.
• D. The Secretary of Defense.

Answer: (A)

The principal military advisor to the President, the Secretary of Defense, and the National Security Council is the Chairman of the Joint Chiefs of Staff. This position serves as the senior uniformed officer who coordinates input from the service chiefs and presents military options and assessments to civilian leadership. The chairman’s role is to advise and synthesize military considerations, not to command forces, which is why this person is the go-to advisor for military matters at the highest levels. The other roles are essential leaders within their own domains—the Secretary of the Navy oversees the Navy, the Chief of Staff of the Army is the top Army officer advising within its service, and the Secretary of Defense is the civilian head of the entire department. While they all contribute to military policy and strategy, the one designated to provide the principal military advice to the President and NSC is the Chairman of the Joint Chiefs of Staff.
