What do the Joint Chiefs of Staff do?

• A. Advise the President and SECDEF on military matters.
• B. Coordinate space exploration missions.
• C. Draft national budget.
• D. Administer base housing.

Answer: (A)

The main idea is that the Joint Chiefs of Staff exist to provide military advice to civilian leadership. They bring together the senior uniformed leaders from each service to assess readiness, capabilities, and policy, and to present informed recommendations to the President and the Secretary of Defense (with the Chairman serving as the principal military advisor to those leaders and the NSC). They don’t have operational control over forces in peacetime; decisions and command authority come from civilian leadership and the combatant commanders. Activities like coordinating space missions, drafting the national budget, or administering base housing fall to other agencies or DoD components, not the Joint Chiefs.
