Which of the following is NOT a type of contracting support?

• A. Theater support
• B. External support
• C. Systems support
• D. Contractor management

Answer: (D)

The key idea is distinguishing how contracting support is delivered versus how contracts are governed. The best choice identifies that contractor management isn’t a type of contracting support itself; it’s the governance function that oversees contracted resources. The other options describe actual ways contracting support is provided: theater support covers contracting at the theater-wide level to sustain operations; external support comes from non-organic sources outside the unit; system support focuses on maintaining and sustaining systems and equipment through contracted services. Contractor management would span across these modes, overseeing performance, compliance, and risk, rather than defining a distinct mode of contracting support.
