The NWCG categorizes information on fire apparatus into logical groups and provides common options often requested by fire managers. The Incident Command System (ICS) uses this system based on the equipment capability. The table below shows NWCG minimum performance requirements for structure and, wildland engine resource types. Additional information for required crew training and equipment recommendations can be found at the position catalog.

This section lists many of the different initial attack engines used in the United States and describes the wide variety of vehicle sizes, pump, and tank size configurations. The data displayed in this section are intended to assist individuals interested in outfitting an initial attack wildland engine. Some of the following engines could possibly be reclassified from one NWCG ICS type to another by changing the basic equipment compliment, personnel staffing, or level of training.
