Which organizational level is responsible for major segments of incident operations?

The organization level responsible for major segments of incident operations is the Branch. In an incident command structure, branches are utilized to divide the operational components of an incident and enable more efficient management of resources and personnel.

Branches are typically responsible for overseeing multiple units and ensuring that various tasks are coordinated effectively to achieve the incident's objectives. By organizing operations into branches, the Incident Commander can focus on strategic decisions while supporting supervisors within those branches manage the day-to-day activities of their respective units.

In the context of incident management, sections represent larger divisions that include branches, but it is the branch level that specifically handles substantial segments of the incident's operations. Units, on the other hand, operate under branches and focus on specific tasks, while a task force is a specific group of resources assembled for a particular purpose, often combining multiple agencies or specific units.
