Who is the Commander in Chief of the military?

The Commander in Chief of the military is the President of the United States. This role is established in the U.S. Constitution, specifically in Article II, Section 2. As Commander in Chief, the President has ultimate authority over all branches of the military and is responsible for making key decisions regarding national defense and military operations. This position underscores the principle of civilian control over the military, ensuring that military decisions are made by elected leaders rather than military officials. The importance of this role reflects the foundational structure of American governance, where elected officials are accountable to the people.

The other roles mentioned, such as the Secretary of Defense, Chief Justice, and Vice President, have specific functions in government but do not hold the title or the powers of Commander in Chief. The Secretary of Defense oversees the Department of Defense and advises the President on military matters, while the Chief Justice heads the judiciary, and the Vice President assists the President and steps in when necessary, but none are designated as the Commander in Chief.
