Which two personnel are responsible for leading reconnaissance and initial site assessment?

• A. The S2 Security Officer and Assistant Element Leader
• B. The CBRN R&S Element Leader and Assistant Element Leader
• C. The Decontamination Team Leaders
• D. The Medical Evacuation Lead

Answer: (B)

Leading reconnaissance and initial site assessment in a CBRN context falls to the CBRN reconnaissance and surveillance (R&S) element leader and their assistant. This team is trained to quickly survey the area, detect CBRN hazards, establish contamination boundaries, identify entry points and routes, and gather the information needed to guide protective actions and mitigation. Their role centers on shaping the initial understanding of the scene so the rest of the team can plan decon, medical support, and security measures appropriately. The S2 Security Officer focuses on security intelligence at a higher level rather than field reconnaissance leadership, the Decontamination Team Leaders concentrate on decon operations, and the Medical Evacuation Lead handles casualty evacuation planning.
