Who serves as the Commander in Chief of the military?

The President of the United States serves as the Commander in Chief of the military as established by the Constitution. This role gives the President the ultimate authority over the nation's armed forces, which includes making key decisions regarding military operations, strategy, and readiness. The President can direct military actions, though significant military engagements often involve consultation with Congress.

This constitutional provision reflects the principle of civilian control of the military, ensuring that military power is overseen by elected officials who are accountable to the public. The position is pivotal in ensuring that military actions align with the nation's political goals and values.

The other choices include positions that, while important in defense and judicial roles, do not hold the specific title or constitutional authority of Commander in Chief. The Vice President supports the President but does not have direct command over the military. The Secretary of Defense leads the Department of Defense and executes military policy but reports to the President, who retains commanding authority. The Chief Justice's duties are primarily judicial and do not encompass leadership over the military forces.
