Which of the following is NOT a mission variable?

Which of the following is NOT a mission variable?

• A. Mission
• B. Terrain
• C. Time
• D. Weather

Answer: (D)

In this framework, mission planning uses METT-TC factors, and terrain and weather are treated as one combined variable because weather conditions directly affect how the terrain is navigated and used. Weather by itself isn’t considered a separate mission variable; it’s embedded with terrain under the single “Terrain and Weather” factor. The other items—the mission, the time available, and the terrain portion—are all part of the mission-variable set. So weather is not a standalone mission variable, making it the correct choice.
