What is the purpose of area reconnaissance?

• A. To confirm or deny the presence of suspected CBRN hazards within a given area.
• B. To locate the hazard in a grid pattern.
• C. To collect samples for analysis.
• D. To determine the exact hazard type.

Answer: (A)

Area reconnaissance is the rapid check of a location to see if suspected CBRN hazards are present and how far they might extend. The best choice captures this core purpose: quickly confirming or denying the presence of hazards within a defined area so you can decide on protective actions, access, and what to do next.

Locating the hazard in a grid pattern describes a detailed mapping task, which is more about precise positioning than the initial confirmation step. Collecting samples for analysis is something done after hazards are identified to characterize them, not the primary aim of the reconnaissance itself. Determining the exact hazard type requires more detailed analysis and testing beyond the scope of an initial survey.
