Communications and rehab are under the __________ logistic branch of ICS.

The answer is service. In the Incident Command System (ICS), the logistics branch is responsible for providing support to ensure that effective operations can occur. This includes managing all the resources and services needed to support incident operations, such as communications, medical care, and rehabilitation of personnel.

The service aspect of the logistics branch covers functions that enhance and maintain the operational capacity of other branches. Communications play a critical role in coordinating efforts and ensuring that teams are equipped with the information necessary to perform their roles efficiently. Rehab is equally important, as it provides relief and recovery for personnel, allowing them to perform optimally throughout the incident response.

The other categories within the logistics branch—support and operations—focus on different aspects. Support generally involves managing supplies, facilities, and equipment while operations focus on the tactical elements of incident response, like firefighting or rescue efforts. Command, on the other hand, is reserved for leadership and decision-making functions, rather than logistical support. Thus, service accurately captures the essence of logistics related to communications and rehabilitation in the context of ICS.
