What type of ICS structure is established when multiple Incident Commanders coordinate their activities?

The type of Incident Command System (ICS) structure established when multiple Incident Commanders coordinate their activities is known as Unified Command. This structure is particularly essential in situations where multiple jurisdictions or agencies are involved in managing an incident.

Unified Command allows agencies to share the responsibility of command without diminishing the authority of any participating agency. It facilitates cooperation among various organizations while maintaining a clear line of communication and decision-making, which is crucial during complex emergencies or disasters where resources, information, and leadership may come from different sources.

Unified Command ensures a collaborative approach, allowing all involved commanders to integrate their individual strategies and objectives into a cohesive response plan. This not only enhances efficiency but also ensures that all stakeholders are on the same page regarding the goals and tactics deployed during the incident management process.

In contrast, the other options refer to command structures that either do not accommodate multiple Incident Commanders working together or serve different purposes. For example, Single Command involves a single Incident Commander overseeing the incident without the complexities of multiple agencies or jurisdictions. Group Command and Multi-Agency Command are not standardized terms within ICS, making Unified Command the correct and precise terminology for the situation described.
