Example: President Harry S. Truman directed U.S. military involvement in the Korean War in 1950 while Congress continued to exercise its constitutional powers over funding and military policy.

Common misconception: Commander in Chief means the President has unlimited power to use the military for any purpose. Presidential authority is constrained by the Constitution, statutes, and other legal requirements.
