In large metropolitan areas, fire companies are often categorized by their primary mission--there are "truck" companies, "ladder" companies, "hose" companies, and "engine" companies, among others.  In reality, in a town the size of McCandless, each of the fire companies is called upon to perform a variety of missions--each supporting the other with the personnel and equipment at hand.  The motto of the McCandless fire "battalion" could very well be "We'll do it.  ...What is it?"  That said, Highland  is a "truck" company in philosophy and their approach to training.

What, exactly, is a "Truck" company, and what is its mission?  The answer to that question can be summarized by an acronym: LOVERS-U.
L LADDERS--  A Truck company has primary responsibility for placing ladders around a structure under fire--at ground level, on roofs and aerial platforms--to provide entry for attack, rescue of victims and (if necessary) rapid egress of firefighters.
O OVERHAUL--Generally (though not always) conducted after the fire is extinguished, overhaul is the process of opening up enclosed spaces (such as inside walls or under roofs) to search for and eliminate "hot spots" which might cause a fire to re-kindle.
V VENTILATION--An enclosed fire area, full of superheated smoke but very little oxygen, presents a great flashover hazard to engine crews conducting the primary inside attack with hose lines on a fire.  By ventilating, or opening exhaust ports in strategic locations in a building's walls or roof, truck companies help to manage the fire's behavior.
E ENTRY--Often of the "forcible" sort.  Attack crews can't do much against interior fires if they can't reach them, and fires often occur behind locked doors.  Truck crews use power- and hand-tools (and a fair amount of brute force) to remove locks from doors, remove doors from hinges, and create "doors" in walls where there had been none.
R RESCUE--The primary mission of all McCandless fire companies is to "protect lives and property."  Truck crews are well-trained in primary and secondary searches for entrapped victims.  This is a a job best performed on the hands and knees, by touch rather than sight inside the smoky black depths of a structure fire.
S SALVAGE--The other side of the "Overhaul" coin, salvage involves the protection of undamaged property from smoke, water, and Overhaul itself.  Salvage operations direct water runoff and move or cover property so as to retain as much of its value as possible.
U UTILITIES--Specifically, controlling public utilities to facilitate an orderly fireground.  Natural gas supplies must be shut off quickly to reduce the chance of explosion, and electricity is a particular hazard to firefighters who frequently work soaking wet and at the end of a solid stream of water, which is as good a conductor of current as an iron bar.
