Which of the following is a PIR type?

• A. Enemy morale
• B. Supply status
• C. Weather
• D. Enemy communications

Answer: (C)

Priority Intelligence Requirements are the information a commander must have to make timely and informed decisions. Among the standard PIR categories, weather information stands out as its own type because it directly shapes planning and execution. Weather affects visibility, terrain mobility, weapon and aircraft performance, and overall risk—factors that drive timing, routes, and logistics. Knowing the weather in advance lets planners anticipate delays, choose safer routes, or adjust fire and maneuver to remain effective.

Enemy morale, supply status, and enemy communications are important indicators and would be tracked, but they aren’t considered separate PIR types in the same way weather is. They contribute to the broader understanding of the enemy or logistics, rather than defining a standalone category of information needed for decision-making.
