The document founding the authority to use force to defend U.S. troops is the:

• A. Tonkin Gulf Resolution
• B. National Defense Authorization Act
• C. Affordable Care Act
• D. Labor-Management Relations Act

Answer: (A)

Understanding who has the authority to use force to defend U.S. troops is about congressional authorization for military action. The Tonkin Gulf Resolution granted the president broad authority to take all necessary measures to repel and prevent further armed attacks against U.S. forces in Southeast Asia, effectively enabling expanded U.S. military action in Vietnam. This is the specific legal basis that allowed or supported escalating force in defense of troops there. The other items serve different purposes: funding and policy for the armed forces (National Defense Authorization Act), health care reform (Affordable Care Act), and labor relations between employers and unions (Labor-Management Relations Act). So the Tonkin Gulf Resolution is the correct source of authority in this context.
