What is the ICS term for companies/crews working within the same geographical area?

• A. Unit
• B. Division
• C. Group
• D. Branch

Answer: (B)

In the Incident Command System, resources are organized either by geography or by function. When the emphasis is on a specific geographic area, that area is called a Division. The Division Supervisor coordinates all personnel and resources operating within that geographic segment, keeping operations localized and clear about who is responsible for which part of the map. If the focus were on a function rather than place—like search, medical, or ventilation—that would be a Group. A Branch is used to split the Operations Section into separate parts at a higher level, usually when the incident is large enough to require multiple Divisions or Groups. Units are the specialized subelements within Divisions or Groups (handling specific tasks like weather, timekeeping, or data management). So for crews working in the same geographic area, the appropriate term is Division.
