The oath of enlistment commits to defend which document?

• A. The Declaration of Independence.
• B. The Constitution.
• C. The Bill of Rights.
• D. The Federalist Papers.

Answer: (B)

The oath to enlistment commits service members to defend the Constitution of the United States, which is the nation's supreme law and the framework for how the government operates. By swearing to support and defend the Constitution against all enemies, foreign and domestic, you pledge to uphold the legal order that gives authority to the military, protects civil liberties, and maintains civilian control of the forces. The Declaration of Independence is a historical statement of principles, not the legal instrument that directs military duty; the Federalist Papers are historical essays advocating ratification, not binding law; the Bill of Rights is part of the Constitution, not a separate document the oath targets.
