The Family of Medium Tactical Vehicles (FMTV) is a series of vehicles that was manufactured by BAE Systems Land and Armaments (until 2011) based on a common chassis, which vary by payload and mission requirements. The FMTV were derived from the Austrian military truck Steyr 12M18. The Light Medium Tactical Vehicle (LMTV) has a 2.5-ton capacity (cargo and van models). The 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 humvees 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.
The cab-over FMTV replaces obsolete and maintenance-intensive 2.5 ton and 5 ton M35 and M939 series of trucks previously in the fleet and performs local and line haul, unit mobility, unit resupply, and other missions in combat, combat support and combat service support units. It is rapidly deployable worldwide and operates on primary and secondary roads, trails, and cross-country terrain, in all climatic conditions. Commonality of parts across truck chassis variants significantly reduces the logistics burden and operating and support costs. New vehicle applications are being developed to meet new requirements.
The FMTV A1 series includes a 1999 Environmental Protection Agency–certified engine, upgraded transmission, electronic data bus, an anti-lock brake system and interactive electronic technical manuals.
The FMTV shares its drivetrain with the Caiman MRAP vehicle.[1]

On February 27, 2009, the United States Army Tank Automotive and Armaments Command issued a solicitation for the upcoming round of FMTV procurement. BAE, Oshkosh Defense (a division of Oshkosh Corporation), and Navistar submitted proposals by the May 27 closing date.
Oshkosh Defense won the award on August 26, 2009. Navistar and BAE were debriefed on September 2 and 3, respectively, after which time both companies protested the award.
On December 14, the U.S. Government Accountability Office upheld the protests, but on February 12 the United States Army again awarded the contract to Oshkosh Defense.[2][3]
On 11 May 2010, Oshkosh reported a trucks and trailers delivery order from the U.S. Army valued at more than $410 million for the production and delivery between March and December 2011 of 2,634 FMTV trucks and 404 trailers. There were several subsequent orders in 2010, the largest being an order for 2060 FMTVs in September 2010.[4]
SUBJECT: Safety Of Use (SOU) Message, TACOM Life Cycle Management Command, (TACOM LCMC) Control No. SOU 11-013, "Technical", Family of Medium Tactical Vehicles (FMTV) Long Term Armoring Strategy (LTAS) Hydraulic Brake converter. This is a Technical Safety of Use Message. a. Brake converters used in early production of the LTAS FMTV are susceptible to damage due to overstroke. Overstroke can occur by pumping the brake pedal when there is air or a leak in the hydraulic brake system. Versions of the IETM dated prior to 30 Sep 2010, New Equipment Training, and SOUM 11-005 incorrectly instruct maintainers to pump the brake pedal to bleed air from the brake hydraulic system. b. Expected results if failure occurs: damage to the brake converter results in degraded brake performance or vehicle pulling sharply to the left or right during heavy braking.
