What is the difference between a primary billet and a collateral duty?

• A. A primary billet is temporary; a collateral duty is the main assigned duty.
• B. A collateral duty is the main assigned duty; a primary billet is an additional duty.
• C. A primary billet is the main assigned duty; a collateral duty is an additional duty assigned to support the unit.
• D. Both are the same; no difference.

Answer: (C)

The key idea is the distinction between the main job you’re officially assigned and an extra duty that supports the unit. A primary billet is the main assigned duty—the core role you’re responsible for as your primary function. A collateral duty is an added responsibility you take on to support the unit’s mission, but it isn’t your main task. That’s why the correct statement is that the primary billet is the main assigned duty and the collateral duty is an additional duty assigned to support the unit. The other options mix up which role is primary, imply the primary billet is temporary, or say there’s no difference.
