CBRN R&S elements must have a minimum of how many personnel?

• A. One person
• B. Three personnel
• C. Two personnel
• D. Four personnel

Answer: (C)

In CBRN reconnaissance and sampling tasks, teamwork and safety hinge on having a buddy system. Two personnel provide the essential coverage of roles: one person can operate the sensing equipment, collect measurements, and communicate findings, while the other remains as a safety partner who monitors the environment, handles PPE and decontamination readiness, and can assist or retreat if conditions worsen. This pairing also allows cross-checking readings and quick response if a parameter becomes unsafe. In the unpredictable, hazardous CBRN environment, this minimum of two ensures continuous monitoring and safer operation, with the option to add more personnel as needed for complex missions.
