Lesson 2
The type of unit you are assigned to will determine the type of wheeled vehicles you will work on.
In an infantry unit, most of the vehicles will fall within the general purpose category, such as 1/4-
ton trucks, 1 1/4-ton trucks, 2 1/2-ton cargo trucks, and so forth. If you are in an engineer unit,
most of your work will probably be on dump trucks. If you are in a transportation unit, you may
be working on cargo trucks, truck-tractors, or semi-trailers most of the time.
The wheeled vehicles discussed below represent some you will see most often, but all military
vehicles are not listed. To list all the vehicles used in the Army would take many pages.
As you read the information about each vehicle, study the illustration to get accustomed to the
appearance of each model and be able to distinguish each one from the other.
UTILITY TRUCKS
The 1/4-ton, 4x4, utility trucks are designed for use on all types of roads and cross-country terrain
in all weather conditions. The vehicle has four driving wheels; front-wheel drive may be engaged
when road and terrain conditions require. It is powered by a four-cylinder, in-line, liquid-cooled,
gasoline engine and has four-wheel hydraulic service brakes and a mechanical hand brake that
operates with a contracting band on the transmission-transfer brake drum. Wheels are individually
suspended on coil springs. The body is of unitized construction.
