How can you say that civilian authority is at all times supreme over the military sight some example?

Civilian authority is considered supreme over the military to ensure that military power is always aligned with democratic principles and the rule of law. For example, in the United States, the President, as the Commander-in-Chief, is a civilian leader who makes ultimate decisions about military actions. Furthermore, the War Powers Resolution requires congressional approval for extended military engagements, reinforcing civilian oversight. Historical instances, such as the dismissal of General Douglas MacArthur by President Truman during the Korean War, illustrate how civilian leaders can assert authority over military commanders to maintain democratic control.
