In ICS, which structure describes the command and coordination during a base incident?

• A. Section Chiefs (Operations, Planning, Logistics, Finance) organize functional areas; Incident Action Plan guides actions; Incident Commander leads overall response; clear communications with EOC as needed.
• B. Chief of Police alone handles all decisions.
• C. Only Operations section is used.
• D. Volunteers run the incident with no defined plan.

Answer: (A)

In ICS, command and coordination on a base incident is organized around a formal structure where an Incident Commander leads the response and delegates to functional sections: Operations handles the tactical work, Planning develops and communicates the Incident Action Plan, Logistics provides the necessary resources and support, and Finance/Administration tracks costs and procurement. The Incident Action Plan serves as the central guide for actions during the period, and clear communications with the Emergency Operations Center keeps higher authorities and external partners aligned.

This setup ensures unified command, accountability, and scalable response across multiple agencies or units. The other options don’t fit because a single person making all decisions lacks the breadth of expertise and oversight required; using only one section ignores critical planning, logistics, and financial controls; and volunteers with no defined plan cannot achieve coordinated, safe, and effective incident management.
