What is the term used for the president as commander of the nation's armed forces?

The correct term for the president as the leader of the nation's armed forces is "Commander in Chief." This designation is established by the Constitution in Article II, Section 2, which grants the president the authority to command the military. This role involves overseeing military operations, making crucial decisions regarding national security, and collaborating with military leaders. The title emphasizes the president's ultimate responsibility for the direction and strategy of the country's armed forces.

While "Chief of Staff" typically refers to a senior aide to the president who manages the presidency's staff or personnel, it does not describe the president's military authority. "President of the United States" is a broader title that encompasses all the duties and roles of the presidency, not specifically the military command. "Supreme Commander" is a title more commonly used in specific contexts, such as during wartime or in certain military alliances, but it is not the standard term for the president's role regarding the armed forces in the United States.
