Western Star M4866S Heavy Engineering Support Vehicle

     Notes: This truck is not designed to carry personnel, but is instead to meant to carry large pallets, containerized cargo, and special bodies such as radar units and huge tanker bodies.  The vehicle is equipped with a sleeper cab, and the cab is suspended onto the truck frame to reduce shocks being transmitted to the cab, with high-backed air suspension seats further reducing crew fatigue.  Power is provided by a Caterpillar C12 turbocharged diesel developing 410 horsepower, coupled with an Allison HD4860P automatic transmission. The suspension is 6x6 and features locking differentials and antilock brakes. Variants include a three-way dump truck and a tractor trailer.  The passenger load shown below is if the vehicle is provided with improvised seating for troops, something that is possible but not likely; basically, this is by putting a cargo truck’s rear cargo bed on the HESV.

Western Star M4800 Medium Logistic Vehicle

     Notes: This is a high-mobility medium truck used by Canada.  The MLV comes in two versions, a 4.32-meter wheelbase with a capacity of 5 tons, and a 5.08-meter wheelbase with a capacity of 7 tons.  The radiator and cooling system are capable of keeping the engine within operating temperatures up to 60 degrees Celsius.  The truck is primarily produced with an automatic transmission, but manual transmissions are available. The M4800 is powered by a Caterpillar M3116TA diesel developing 220 horsepower. The engine is underpowered for this class of truck, especially in the LWB version. The suspension is 4x4 and the truck has a central tire inflation regulation system which is automatic and computer controlled. A winch with a capacity of 8 tons may be mounted either in the front or the center of the vehicle; when front-mounted, the cable may be led out only to the front, but if center-mounted, the cable may be led out to the front or rear of the truck.  Some of these vehicles have an enlarged cab to hold 6 people; these are normally used to tow artillery pieces or carry antiaircraft guns.  Variants include a fire engine, a version that is strengthened for parachuting, a tanker, and a wrecker.

Bombardier TF-300-TT

     Notes: This is a heavy truck used to carry very heavy cargoes.  The front and rear are attached by a ball joint that enhances cross-country mobility.  There is an escape hatch in the roof of the cab, and the cab is heated and air conditioned.  The engine is the same as that on the M113A2 APC, a Detroit Diesel 6V53T turbocharged diesel developing 212 horsepower; it is rather underpowered for its task, but provides a great deal of torque for towing or in cross-country mobility. Optional equipment includes a 10-ton winch in the front or center of the vehicle and a load-handling crane with a capacity of 5 tons behind the cab; if equipped with a crane, the truck will also have two outrigger legs which are to be lowered when using the crane. As the TF-300-TT has an insulated cab which has a more than adequate heater, the cab can become quite snug in cold weather.
