E. Air Operations Branch

The Operations Section is responsible for managing tactical operations at the incident site directed toward reducing the immediate hazard, saving lives and property, establishing situation control, and restoring normal conditions. Incidents can include acts of terrorism, wildland and urban fires, floods, hazardous material spills, nuclear accidents, aircraft accidents, earthquakes, hurricanes, tornadoes, tropical storms, war-related disasters, public health and medical emergencies, and other incidents requiring an emergency response.

Because of its functional unit management structure, the ICS is applicable across a spectrum of incidents differing in size, scope, and complexity. The types of agencies that could be included in the Operations Section include fire, law enforcement, public health, public works, and emergency services, working together as a unit or in combinations, depending on the situation. Many incidents may involve private individuals, companies, or nongovernmental organizations, some of which may be fully trained and qualified to participate as partners in the Operations Section.

Incident operations can be organized and executed in many ways. The specific method selected will depend on the type of incident, agencies involved, and objectives and strategies of the incident management effort. The following discussion presents several different methods of organizing incident tactical operations. In some cases, a method will be selected to accommodate jurisdictional boundaries. In other cases, the approach will be strictly functional. In still others, a mix of functional and geographical approaches may be appropriate. The ICS offers extensive flexibility in determining the appropriate approach using the factors described above. Figure 2-A shows the primary organizational structure within the Operations Section.

A. OPERATIONS SECTION CHIEF.

The Operations Section Chief directly manages all incident tactical activities and implements the IAP. The Operations Section Chief may have one or more deputies (preferably from other agencies in multijurisdictional incidents). Deputies will be qualified to a similar level as the Operations Section Chief. An Operations Section Chief should be designated for each operational period and will have direct involvement in the preparation of the IAP for the period of responsibility.

B. DIVISIONS and GROUPS.

Divisions and groups are established when the number of resources exceeds the Operations Section Chief’s manageable span of control. Divisions demarcate physical or geographical areas of operation within the incident area. Groups demarcate functional areas of operation for the incident. See Figure 2-B.

The use of the two terms is necessary, because division always refers to a geographical assignment and group always refers to a functional assignment. Both divisions and groups may be used in a single incident if there is justification for their use and if proper coordination can be effected.

As additional types of resources are added to the organization, resources should be assigned into a division structure. See Figure 2-C.

C. RESOURCE ORGANIZATION.

Initially, in any incident, individual resources that are assigned will report directly to the IC. As the incident grows in size or complexity, individual resources may be organized and employed in a number of ways to facilitate incident management:

D. BRANCHES.

Branches may be established to serve several purposes including the following:

2. The Nature of the Incident Calls for a Functional Branch Structure.
For example, if a large aircraft crashes within a city, various departments within the city (including police, fire, emergency services, and public health services) would each have a functional branch operating under the direction of a single Operations Section Chief. In this example (see Figure 2-G), the Operations Section Chief is from the fire department, with deputies from police and public health services. Other alignments could be made, depending on the city plan and type of emergency. Note that, in this situation, the Incident Command could be either a single command or Unified Command (UC), depending on the jurisdiction.

E. AIR OPERATIONS BRANCH.

The Operations Section Chief may establish an Air Operations Branch to meet mission requirements in certain situations, in which size, organization, and operation will depend primarily on the nature of the incident and the availability of air assets.* Figure 2-I shows a typical organizational structure for air operations.

The Operations Section Chief may designate a director for the Air Operations Branch when the complexity of air operations requires additional support and effort or when the incident requires mixing tactical and logistical utilization of helicopters and other aircraft. Flight safety is a paramount concern in complex operations and supports the requirement for a designated Air Operations Branch to ensure the deconfliction of assets and the integration of safety considerations into operational planning and mission execution. Whenever both helicopters and fixed-wing aircraft must operate simultaneously within the incident air space, a Air Tactical Group Supervisor should be designated. This individual coordinates all airborne activity with the assistance of a helicopter coordinator and a fixed-wing coordinator. When only one helicopter is used, however, the helicopter may be directly under the control of the Operations Section Chief.

The Air Support Group establishes and operates bases for rotary-wing air assets and maintains required liaison with off-incident fixed-wing bases. The Air Support Group is responsible for all timekeeping for aviation assets assigned to the incident.

* Air Operations Branch is used here as an example and may not be applicable to all ICS organizations.
