Which of the following best describes unified command in multi-jurisdictional incidents?

• A. An external command post replaces all local leaders.
• B. Representatives from involved agencies share authority, operate under a single IAP, and appoint a single Incident Commander.
• C. A single agency makes all decisions for the operation.
• D. The ICS structure is bypassed in favor of a loose coalition.

Answer: (B)

Unified command is used when response involves multiple jurisdictions or agencies, so leadership is shared rather than handed to a single entity. In this approach, representatives from all involved agencies participate in decision-making, work under one unified Incident Action Plan, and appoint a single Incident Commander to lead the operation. This ensures coordinated strategy, consistent communications, and efficient use of resources while each agency retains its authority and expertise. It also keeps the incident under a formal ICS structure, rather than replacing local leaders with an external post, letting one agency dictate all actions, or operating as a loose coalition without a unified plan or command.
