The Family of Medium Tactical Vehicles (FMTV) is a series of vehicles, based on a common chassis, that vary by payload and mission requirements. FMTV vehicles were manufactured by Stewart and Stevenson (1996-2006) and then Armor Holdings (2006-2007) and then BAE Systems Land and Armaments until 2011 when Oshkosh Corporation began producing the fleet. The FMTV were derived from the Austrian military truck Steyr 12M18. The 4x4 Light Medium Tactical Vehicle (LMTV) has a 2.5-ton capacity (cargo and van models) while the 6x6 Medium Tactical Vehicle (MTV) has a 5-ton capacity (cargo and long-wheelbase cargo with and without material handling equipment, tractor, van, wrecker, and dump truck models). Three truck variants and two companion trailers, with the same cube and payload capacity as their prime movers, provide air drop capability. M1078s have been deployed to Iraq with armored cabs with roof gun mounts with shields, similar to those fitted on High Mobility Multipurpose Wheeled Vehicles (HMMWV) and M113s. Beginning in October 2010, Oshkosh Corporation commenced production on their newly awarded "re-buy" contract. The last truck built under the S023 contract in TX was produced by BAE in June 2011.
