What organizational level handles major functional areas in ICS?

The organizational level that handles major functional areas in the Incident Command System (ICS) is the Section. In ICS, Sections are responsible for the primary functions such as Operations, Planning, Logistics, and Finance/Administration. Each Section is led by a Section Chief who reports directly to the Incident Commander and is responsible for coordinating the activities and resources within that particular functional area.

This structure allows for effective management and organization of incident response, as each Section may be further divided into Branches and Units to address specific tasks or needs within that area. By clearly defining these major functional areas, the ICS facilitates coordination and communication both within and between organizations during an incident, ensuring that all aspects of the response are being managed efficiently and effectively.
