CET Skid Unit - Attack Pac
A tank, a live hose reel and/or crosslay, a portable fire pump and/or a compressed air foam system (CAFS), with an engine: these can be combined into a single one-piece assembly that can be slipped onto a truck bed, trailer, or into a body and used for flowing water and or foam on a structural fire, car fire or wildfire.
The most common wildland and urban interface fire engines in North America combine a small truck with a water tank and a high performance portable pump. Municicpal/industrial fire departments and all forestry fire authorities use drop-in units. The sizes vary from 50 gallons, for an ATV, up to 500 gallons for full size trucks.
