In the Incident Command System, facilities are specialized hubs with distinct purposes. The Base serves as the central logistical hub where personnel and equipment are housed and where support operations—like supply, maintenance, and admin functions—are coordinated. That makes it the go-to location for gathering and sustaining resources and staff for the incident, which is exactly what’s being asked when asking about housing people and gear and providing ongoing support.

The Rehab Area, by contrast, is focused on responder rest, hydration, and medical evaluation; it isn’t a hub for housing all personnel or coordinating logistics. The Staging Area holds resources that are ready to be deployed but not yet assigned to tasks, so it doesn’t function as the main support base. The Incident Command Post is where the on-scene command and tactical decisions are made, not where the bulk of personnel and equipment are housed or the broader support operations are managed.
