Minimum personnel for a CBRN R&S element?

• A. 1 personnel
• B. 3 personnel
• C. 4 personnel
• D. 2 personnel (3 preferred)

Answer: (D)

The situation tests how many people are required to safely and effectively conduct CBRN reconnaissance and surveillance. You need at least two to cover the essential tasks without overloading a single operator, and to maintain the buddy system that’s critical in potentially contaminated environments. With two people, one can focus on operating the detection gear, identifying hazards, and collecting data, while the other handles safety, communications, and documentation—ensuring continuous operation and protection for the team. Having a third person is preferred because it adds redundancy and allows more uninterrupted coverage: one can assist with decontamination, sampling, or PPE management, another can maintain communications and data flow, and the team can sustain operations longer or handle more complex tasks without compromising safety. So two is the minimum to keep the team functional and safe, with three preferred to maximize safety, coverage, and efficiency.
