What are the responsibilities of the Secretary of Defense?

• A. Conducting frontline combat missions.
• B. Managing civilian personnel.
• C. Formulating defense policy and executing approved policies.
• D. Negotiating international treaties.

Answer: (C)

The key idea this question tests is the role of the Secretary of Defense as the civilian leader who shapes defense policy and ensures it is carried out across the department. The Secretary is responsible for formulating defense policy in coordination with the President and national security partners, setting priorities, and directing how those policies are implemented through programs, budgets, and daily DoD operations. This means turning strategic objectives into actionable plans and making sure the department’s activities align with approved policy.

Frontline combat missions are carried out by military forces under operational commanders, not by the Secretary. Treaties are negotiated by the President with Senate approval, with the Department of Defense providing input, but the actual negotiation and ratification process lie outside the Secretary’s authority. While the Secretary does oversee a large civilian workforce within DoD, the core duty emphasized here is establishing and executing defense policy, not merely managing personnel.
