Which METT-TC element most often drives weather-related planning decisions that affect route selection and timing?

• A. Time
• B. Terrain and Weather
• C. Enemy
• D. Civilian considerations

Answer: (B)

Weather is considered part of the Terrain and Weather element in METT-TC, and it directly shapes how you move and when you move. When planning a route, you assess how the terrain and forecasted conditions will affect mobility, speed, and safety. Weather can make a route passable or impassable, alter travel times, and create hazards you must mitigate, so the choice of route and the timing of movement hinge on how terrain interacts with weather. For example, rain can turn dirt roads to mud, snow and ice slow or block movement, fog reduces visibility, and changing river levels can open or close crossings. These weather-driven effects are why Terrain and Weather most often drive weather-related planning decisions, more so than enemy factors or civilian considerations, which shape different aspects of the plan.
