Which of the following is NOT a PIR type?

• A. Weather
• B. Threat
• C. Terrain
• D. Logistics

Answer: (B)

Understanding what a PIR focuses on helps explain why this choice is not a PIR type. Priority Intelligence Requirements are the information you need to support planning and decision-making about how to move, fight, and sustain the force. The typical PIR categories in this context cover environmental and support factors that directly affect operations: Weather informs timing, visibility, and limits on movement; Terrain covers the ground, obstacles, routes, and how they influence mobility and concealment; Logistics deals with supply lines, fuels, maintenance, and resupply so the force can sustain operations.

Threat, while crucial to understand, is generally addressed as a separate intelligence concern—assessing enemy capabilities, intentions, and order of battle—rather than as one of the PIR types focusing on the environment and sustainment. So, Threat is not considered a PIR type in this set.
