Which is the final task in the eight CBRN reconnaissance tasks?

• A. Report
• B. Survey
• C. Mark
• D. Validate

Answer: (A)

The key idea here is closing the information loop by communicating what you’ve found to the right people. The final task is to report, because only when the gathered data is formally communicated to command or the next element in the chain can protective actions, prioritization, and further planning be carried out. A solid report brings together where you searched, what hazards or indicators you found, how dangerous they are, and what actions you recommend or constrain, along with any limitations or uncertainties. This synthesis turns on-scene observations into actionable decisions for decontamination, routing, protection, or resource allocation.

The other steps are essential parts of gathering and marking the area: surveying collects the data, marking designates locations or hazards for others to see, and validating checks the accuracy and reliability of what you’ve found. They feed into the report, but the final task itself is the formal communication of those findings so the mission can move forward.
