Under what circumstances might an intelligence/investigation section be established within NIMS-ICS?

An intelligence/investigation section within the National Incident Management System - Incident Command System (NIMS-ICS) is typically established in situations where there is a significant threat or risk posed by weapons of mass destruction. This is due to the complex nature of incidents involving such materials, which may require a coordinated response that includes intelligence gathering, analysis, and sharing to accurately assess the situation and protect public safety.

In cases involving hazardous materials or potential terrorist threats, having a dedicated intelligence/investigation section allows for the necessary expertise to understand the implications of such incidents, coordinate with law enforcement agencies, and ensure an effective response that adheres to safety protocols. This section is critical for managing the multifaceted challenges posed by weapons of mass destruction, which can include biological, chemical, or radiological threats that require specialized knowledge and resources.
