In the incident command system, levels added below the section include which elements?

• A. Branches only
• B. Divisions/Groups only
• C. Units/Single Resources only
• D. Branches, divisions/groups, and units/single resources

Answer: (D)

The idea being tested is how the Incident Command System expands below a Section as an incident grows. When more depth is needed to manage multiple objectives, branches are added to handle different lines of effort within a section. Within those branches, divisions or groups subdivide the work by geographic area or by function, so resources focus on specific parts of the operation. Within those divisions or groups, units or single resources are the actual personnel or equipment assigned to carry out tasks.

So all three levels—branches, divisions/groups, and units/single resources—are used below a section to organize work and keep the span of control manageable. For example, in a large incident, one section might have a branch for medical operations, another for search and rescue; within the medical branch, divisions could be by area or function, and within a division you’d have units like a specific team or a single resource such as a medic and their equipment working on a task.
