What is one of the purposes of conducting a site survey during CBRN reconnaissance?

Conducting a site survey during CBRN reconnaissance primarily serves to identify potential hazards present in the environment. This is crucial for assessing the risks associated with the site and understanding what CBRN agents or materials are present. By identifying these hazards, teams can evaluate the extent of contamination, determine safe entry and exit routes, and develop an appropriate response plan. This knowledge not only guides tactical decisions but also helps in ensuring the safety of personnel while operating in or near the contaminated area. Recognizing potential hazards is a foundational step in any reconnaissance mission, as it shapes the overall strategy for mitigation and response.
