The Incident Support Base Unit is the final unit in the External Support Branch. The function of this unit is to establish or execute an ISB. Upon order by higher authority, an Incident Support Base Unit will deploy, occupy, establish, and manage the incident support base until the disaster is declared by the President. After that, the ISB becomes the staging area under the direction of FEMA Operations.
