In ICS, resources are tracked by their availability in three states: assigned, available, and out of service. Assigned means the resource is currently working on an incident or task and isn’t free for dispatch. Available means it’s ready for immediate deployment and can be assigned as needed. Out of service means the resource isn’t usable right now due to maintenance, repair, or other reasons, so it cannot be dispatched until it’s back in service. This three-state framework keeps command aware of what can be deployed next and what needs maintenance or rest, supporting efficient resource management and rapid scaling of operations. Other terms describe activation or post-incident statuses, but they don’t form the standard three-state availability model used in ICS resource management.
