A frankenstein contraption we use for training in firefighting. Designed to have a variety of features likely to be found and be in various states of on fire.
The big thing is cooling the ordnance pods or fuel tanks. The engine is designed to be on fire, you want to keep the fire off the scary stuff. Unless you have something that can actually cut off air - like AFFF. Stuff makes great boot stripper, by the way… if you don't care about having a boot a year or so later.
