What is the minimum personnel in a CBRN R&S element?

• A. 1
• B. 3
• C. 2
• D. 4

Answer: (C)

Two personnel are needed because CBRN reconnaissance and survey relies on a buddy system to safely operate in potentially hazardous environments. While one person conducts measurements, samples, and observations with detection gear, the other monitors safety, handles communications, assists with donning and doffing PPE, supports decontamination, and documents results. This setup allows cross-checking of readings, ensures someone is always watching for exposure, and provides immediate assistance if decontamination or an emergency is required. Doing all these tasks alone would stretch a single person too thin, increasing the risk of exposure, missed data, or improper procedures.
