Which task follows Collect in the eight CBRN reconnaissance tasks?

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

Answer: (A)

In CBRN reconnaissance, actions are ordered to turn scattered data into a usable map of the hazard. After collecting data or samples, the next step is to survey the area to map how far the contamination has spread, define its boundaries, and identify any additional affected zones. This surveying creates a spatial picture from the collected information, which is essential for planning the subsequent actions. Once the area has been surveyed, marking hazard locations, reporting the findings, and quantifying the contamination can be done accurately and efficiently. So, surveying immediately after collecting is the natural next step because it expands and validates the data into a coherent understanding of the hazard.
