Which of the following is not a component of detailed information gathered during route reconnaissance?

Detailed information gathered during route reconnaissance focuses on specific elements that directly impact movement and operational effectiveness. The correct response highlights that general weather conditions, while pertinent to broader mission planning, do not constitute a detailed component of route reconnaissance.

When conducting route reconnaissance, the emphasis is on tangible and immediate factors that could affect troop movement and logistics. This includes specific terrain features that might hinder or facilitate movement, enemy positions that pose potential threats along the route, and obstacles such as rivers, hills, or obstacles placed by the enemy that would require diversion or caution.

In contrast, general weather conditions are less precise and can change frequently, making them less practical for immediate mission execution compared to the other categories that provide actionable intelligence. Therefore, option C is not aligned with the specific focus of detailed reconnaissance information.
