Logistics Section provices the service and support of the incident. The six equally important functions of the Logistics Section are Communications, Medical, Food, Supply, Facilities, and Ground Support. An incident couldn't be worked if any of these functions didn't exist. In some form - each must exist at an incident. In larger incidents, the six functions can be seperated into two branches, the Service Branch and the Support Branch.
The Service Branch provides direct services to the incident. These include Communications, Medical and Food. These services can be provided anywhere on the incident at a moment's notice if needbe.
The Support Branch supports the underlying needs of the incident such as supplies, providing facilities, and ground support to all the resources on the ground.
