Which of the following is a major function of the Incident Command System (ICS)?

• A. Command
• B. Public Information
• C. Coordination
• D. Documentation

Answer: (A)

In ICS, the big management functions are the five major sections that organize incident control: Command, Operations, Planning, Logistics, and Finance/Administration. The Command function is the leadership role responsible for establishing incident objectives, priorities, and strategy, and for overall safety and direction of the response. It sets the priorities, makes key resource decisions, and maintains overall accountability for the incident.

Public Information is handled by a staff component under Command, focusing on communicating with the public and media, but it isn’t one of the five major management functions. Coordination is an ongoing activity that happens across the ICS structure to ensure different parts of the response work together, not a standalone major function. Documentation relates to record-keeping and is typically part of Planning or general staff procedures, not a primary major function. So the best answer is Command.
