Who is referred to as the "Commander in Chief"?

The title "Commander in Chief" refers specifically to the President of the United States, as outlined in Article II, Section 2 of the U.S. Constitution. This designation grants the President ultimate authority over the nation's armed forces and the responsibility to direct military operations and decisions during times of war and peace. Being the Commander in Chief is a critical aspect of the President's role, as it encompasses not only military leadership but also national security strategy and defense policy.

In contrast, the other positions listed do not hold this mantle. The Vice President serves primarily as the assistant to the President and assumes the presidency if the current President is unable to serve. The Chief Justice of the Supreme Court oversees the judicial branch and is responsible for presiding over court cases, especially those that involve the Constitution, but does not have military command. The Speaker of the House leads the House of Representatives and focuses on legislative matters, without any military authority. Thus, the President's unique role as Commander in Chief is what distinguishes this title.
