In ICS, which command structure is used when multiple jurisdictions or agencies are involved?

• A. Single Command only
• B. Unified Command
• C. No Command
• D. Parallel Command

Answer: (B)

Coordinating across multiple jurisdictions or agencies is handled through Unified Command. In this structure, leaders from all involved agencies work together to define common objectives, establish incident priorities, and make joint strategic decisions, ensuring a single plan and coordinated resource deployment. This eliminates conflicting directions and allows shared accountability for safety and outcomes. Single Command is used when only one agency has authority; No Command isn’t a viable approach in a real incident; Parallel Command isn’t a standard ICS arrangement and can fragment authority and messaging.
