   During the late 1980s the US Army was looking for a new military truck family. The main emphasis was stressed on reliability, low unit and running costs, and long term efficiency. There was a grueling series of selection trials which took place over a period of many months. Eventually an Austrian Steyr design was selected as a winner. In 1991 a Stewart & Stevenson company was awarded a large-scale contract to manufacture the US Army's new Family of Medium Tactical Vehicles (FMTV) with the intention that eventually all the existing (and ageing) medium trucks in the Army's inventory would be replaced by a modern and efficient design. First production vehicles were fielded by the US Army in 1996. Eventually all ageing light and medium trucks in the Army's inventory were replaced by this modern and efficient family of vehicles. Since 2012 these trucks are produced by Oshkosh Corporation. These trucks were offered for export.

   The FMTV is based on an Austrian truck, the Steyr 12M18, but considerably reengineered to be available as the 4x4 2.5 tone Light Medium Tactical Vehicle (LMTV) and the 6x6 5 tone Medium Tactical Vehicle (MTV). Both models have over 90 percent of components in common such as the cab, engine, drive train, tyres, wheels, front suspension, axles, etc, while this design involves many commercially available components. There was also an 8x8 heavy tactical vehicle, however only a couple of its prototypes were built and it never reached mass production. The basic LMTV is the M1078 cargo truck while the 6x6 base is the M1083.

   The M1078 standard cargo truck is designed to transport cargo and soldiers. It has a payload capacity of 2.27 t and to facilitate loading and unloading the bed-side rails are mounted on hinges and can be lowered. The cargo bed can be equipped with an optional bench seat kit for the transport of soldiers. The bench seats are constructed of a non-wood material and attach to the cargo bed side rails, and can be folded down and stowed when not in use. Soldiers are assisted when climbing in and out of the cargo bed area with the aid of a ladder, which is stowed on a vehicle when not in use. A canvas and bows kit are available to keep both soldiers and cargo protected from the elements. The M1078 can be equipped with optional electrically operated self-recovery winch kit capable of fore and aft vehicle recovery operations.

   The cab accommodates driver and two passengers. Experience in Iraq led to development of an armored cab. It is known as Low Signature Armored Cab (LSAC). A team of 2 men can remove and replace the standard cab by an armored cab in the field conditions within 4 hours. The armored cab provides protection for the passengers against small arms fire, artillery shell splinters and mine blasts. These were widely used in Iraq and Afghanistan. Later a new Long Term Armor Strategy (LTAS) armored cab was introduced. It can adapt various armor levels, depending on the threat.

   Vehicle is powered by a Caterpillar 3115 ATAAC 6.6-liter turbocharged diesel engine, developing 225 hp. At the time of its introduction this engine was considered to be highly efficient and had low emissions. Later an improved Caterpillar 3116 engine was fitted. Interestingly the 6x6 version is fitted with a more powerful engine. The engine is coupled to a fully automatic transmission. The truck has power steering. A central tyre pressure system is fitted as standard.

   Some versions of the LMTV are fitted with load handling cranes. Some versions are being produced as bare chassis for special bodies to be added. Both LMTV and MTV models use the same forward control cab which has features such as ease of maintenance and routine checking facilities. A machine gun mounting is provided on top of the roof.

   The M1078 basic model have many variants such as:

   - long wheelbase version;
   - van bodies;
   - dump truck;
   - tractor truck;
   - special version for low altitude air drops.

   Recently a new FMTV A2 family of light and medium tactical vehicles is being developed for the US Army. These will include LMTV A2 and MTV A2 series tactical vehicles. The new vehicles have stretched wheelbases and an added bonnet at the front. Production contract was awarded in 2018. The updated FMTV family is destined to serve well into the 21st Century.
