How many organizational levels make up the Incident Command System (ICS) structure?

Explanation:
The structure is built with a top Command and four major sections beneath it—Operations, Planning, Logistics, and Finance/Administration. This setup keeps authority and responsibilities clear, so functions like directing on-scene work, planning ahead, obtaining and allocating resources, and tracking costs are organized and scalable. The Command Staff (Public Information, Safety, and Liaison) support the top command but aren’t counted as additional levels in the core hierarchy. As incidents grow, you can add branches, divisions, and units within those sections, but the essential framework remains this top command plus four major sections.
