In ICS, what structure is used when multiple agencies with jurisdictional responsibilities operate together?

• A. Area Command
• B. Unified Command
• C. Single Command
• D. Joint Operations Center

Answer: (B)

Unified Command is used when multiple agencies with jurisdiction operate together on the same incident. It brings representatives from each agency to jointly establish incident objectives, share information, and coordinate tactics, while preserving each agency’s authority and accountability. This arrangement produces a single, unified strategic direction and a common Incident Action Plan, along with integrated resource management, so all responders work toward the same goals. A Single Command is when one agency leads on-scene, Area Command oversees a geographic area or multiple incidents, and a Joint Operations Center is a coordination facility—not the on-scene command structure.
