,Section 1: Area Command -- 2026/2027
Q1 Question 1 of 75
A wildfire burning across three counties has expanded beyond the capacity of a single Incident Management
Team. The state emergency operations center establishes an Area Command to oversee multiple incident
management teams assigned to different zones of the fire. The primary purpose of Area Command in this
scenario is to oversee the management of multiple incidents that are each being handled by a separate Incident
Command System organization. The Area Command does which of the following as its core function?
A. Provide overarching strategic direction, set priorities among incidents, and coordinate the
allocation of critical resources across incidents.
B. Directly manage tactical operations on each incident division and assign resources to individual strike
teams on the fireline.
C. Replace the Incident Commanders at each incident and assume direct command of all field operations.
D. Serve as the single point of contact for media inquiries and public information across all incident zones.
Correct Answer: A
Rationale:
Area Command's core function is providing strategic oversight, setting priorities among incidents, and coordinating
resource allocation across multiple incidents managed by separate ICS organizations. Option A describes tactical
operations, which are the responsibility of individual Incident Commanders. Option C is incorrect because Area
Command does not replace Incident Commanders. Option D describes a public information function, not the strategic
oversight role of Area Command.

,Q2 Question 2 of 75
An Area Commander is appointed to manage three simultaneous hurricanes affecting the Gulf Coast. Each
hurricane has its own Incident Commander and Incident Management Team. The Area Commander needs to
establish communication and coordination with each incident. The most appropriate organizational structure for
the Area Command includes which of the following positions?
A. Area Commander, Operations Section Chief, Planning Section Chief, and Logistics Section Chief
B. Area Commander, Deputy Area Commander, and support staff including an Area Command
Public Information Officer, Safety Officer, and Liaison Officer
C. Area Commander, a single Incident Commander who consolidates all three hurricanes into one
incident, and a unified command team
D. Area Commander, Communications Unit Leader, Medical Unit Leader, and Food Unit Leader
Correct Answer: B
Rationale:
The Area Command organization includes the Area Commander, an optional Deputy Area Commander, and support
staff positions such as a Public Information Officer, Safety Officer, and Liaison Officer. Option B incorrectly includes
ICS Section Chiefs, which are not part of Area Command structure. Option C contradicts the purpose of Area
Command by consolidating incidents. Option D lists unit-level positions that belong under the Logistics Section of an
incident, not Area Command.
Q3 Question 3 of 75
During a complex disaster involving widespread flooding, the Area Commander determines that two of the five
incidents require additional resources while three incidents have excess resources. The Area Commander
decides to reassign resources from the over-resourced incidents to the under-resourced ones. This action is an
example of which Area Command responsibility?
A. Tactical direction of firefighting operations on the ground
B. Collecting, evaluating, and disseminating tactical information related to the incident
C. Ensuring that priorities are set among the incidents and that resources are properly allocated
D. Approving and authorizing the release of public information statements
Correct Answer: C
Rationale:
Setting priorities among incidents and ensuring proper resource allocation is a primary Area Command responsibility.
Option A describes a tactical function at the incident level, not Area Command. Option B describes an
information-gathering function, which supports but is not the same as resource allocation. Option D is a public
information function that may be delegated to the Area Command PIO but is not the primary responsibility described in
the scenario.

, Q4 Question 4 of 75
An Area Command has been established for a series of hazardous materials incidents along a major interstate
highway. The Area Commander needs to ensure that each Incident Commander is operating under consistent
objectives. The Area Commander accomplishes this by performing which action?
A. Assigning specific tactical tasks to each Division Supervisor on the fireline
B. Dispatching all available resources to the largest incident and leaving the smaller incidents without
support
C. Communicating directly with individual firefighters instead of going through the chain of command
D. Reviewing and approving incident action plans and objectives for each incident under Area
Command
Correct Answer: D
Rationale:
Area Command reviews and approves incident action plans and objectives for each incident to ensure consistency and
coordination. Option A is a tactical-level action performed by Operations Section personnel at individual incidents.
Option C violates the principle of prioritizing all incidents appropriately. Option D bypasses the chain of command,
which undermines the ICS structure.
Q5 Question 5 of 75
A state emergency manager is considering whether to establish an Area Command for a series of tornadoes
that struck six communities across a 200-mile corridor. The decision to activate Area Command is most
appropriate when which condition exists?
A. Multiple incidents are managed by separate ICS organizations and require strategic-level
oversight and coordination
B. A single incident requires additional Section Chiefs to manage expanding operations
C. One Incident Commander needs a deputy to help manage span of control
D. A local fire department needs mutual aid from a neighboring jurisdiction for a single structure fire
Correct Answer: A
Rationale:
Area Command is activated when multiple incidents, each managed by its own ICS organization, require strategic-level
oversight and coordination. Option B describes expansion within a single incident, not the need for Area Command.
Option C describes a routine delegation within one incident. Option D describes a mutual aid situation for a single
incident, which does not require Area Command.
