How are types of resources categorized in ICS?

In the Incident Command System (ICS), resources are categorized from Type I as the most capable to Type IV as the least capable. Type I resources are the highest level of resources, equipped with the most advanced capabilities and the ability to handle complex incidents. This categorization allows for a standardized understanding of resource capabilities, ensuring that responders can match the type of resources needed for specific incidents with the required operational effectiveness.

Type II and Type III resources follow Type I in diminishing levels of capability, indicating progressively less complex incident management potential until reaching Type IV resources, which are generally used for smaller or less complex situations. This tiered approach aids in effective incident planning and helps incident managers leverage the right resources according to the demands of the incident they are addressing.
