The '''Medium Tactical Vehicle Replacement''' ('''MTVR''') is a family of medium to heavy [[six-wheel drive]] cargo and tactical trucks, used by the [[United States]] [[U.S. Marines|Marine Corps]].<ref name="JanesTrailers">{{cite web |url=https://janes.ihs.com/Janes/Display/1495139|title=Oshkosh (6 × 6) Medium Tactical Vehicle Replacement (MTVR) and trailers|publisher=IHS Jane's|access-date=2015-12-23}}</ref><ref name="JanesMET">{{cite web |url=https://janes.ihs.com/Janes/Display/1501756|title=Oshkosh MK31 Medium Tactical Vehicle Replacement (MTVR) Medium Equipment Transporter (MET)|publisher=IHS Jane's|access-date=2015-12-23}}</ref> The first MTVRs were delivered in late 1999. The MTVR is the equivalent of the [[U.S. Army]]'s [[Family of Medium Tactical Vehicles]] (FMTV); the Marines do not use the FMTV (with the exception of the FMTV-based HIMARS) and the Army does not use the MTVR.

There were originally four, later seven, MTVR variants, then nine (plus a sub-variant) as deliveries and development continued. A dedicated trailer and prototype/developmental MTVRs have also been produced.<ref name="JanesTrailers"/><ref name="JanesMET"/>

The MTVR was designed and is manufactured by [[Oshkosh Corporation|Oshkosh Defense]].<ref name="JanesTrailers"/><ref name="JanesMET"/>

==Development and production history==
The MTVR has its design origins in two U.S. military programs, the 5 ton Tactical Truck Replacement (5TTR) for the [[U.S. Army]], and the Medium Tactical Vehicle Replacement (MTVR) for the [[U.S. Marines]]. The aim of these programs was to upgrade and extend the service life of around 3,400 [[U.S. Army]] [[M939]] series 5 ton trucks, and 8,100 [[U.S. Marines]] [[M809 series trucks|M809]] and M939 series 5 ton trucks. Prototype and development contracts for both programs were awarded in 1996. The 5TTR program was subsequently halted, and the MTVR program evolved from an upgrade to a new-build requirement.<ref name="JanesTrailers"/>

[[Oshkosh Corporation|Oshkosh]] was awarded a multi-year MTVR production contract in February 1999. The first vehicles were scheduled for delivery by the end of 1999, and deliveries under the initial contract concluded during August 2005. The award initially allowed for up to 8,168 MTVRs (including options for 2,502) in four variants (MK23, MK25, MK27, MK28) to be ordered over five program years; 6,931 MTVRs were delivered, 6,393 to the Marines and 538 to the Navy ([[Seabee]]s). The first MTVRs were fielded in July 2001. Three additional variants followed, the MK29, MK30 and MK36.<ref name="JanesTrailers"/>

Under a separate contract, Oshkosh commenced production in July 2004 of a further MTVR variant, the MK37. Based on the MK27 and fitted with a rear-mounted [[Hydrauliska Industri AB|Hiab]] materials handling crane rated at 10,000&nbsp;lb at 10.5&nbsp;ft maximum reach, the MK37 is a resupply vehicle for the U.S. Marines HIgh Mobility Artillery Rocket System ([[HIMARS]]). The companion trailer is designated MK38.<ref name="JanesTrailers"/>

[[Oshkosh Corporation|Oshkosh]] was awarded a second MTVR multi-year contract (FY05-FY10) in July 2004. This award initially covered only potential [[Foreign Military Sales]] (FMS), plus the continuing requirements of the [[U.S. Navy]]. Ultimately the U.S. Navy and Marines combined received >2,000 vehicles under this contract.<ref name="JanesTrailers"/>

In 2005, the MK31 Medium Equipment Transporter (MET) tractor entered service with [[Seabee]]s, and later in the year with the Marines.<ref name="JanesMET"/>

The MK28C is a variant of the MK28. The MK28C (C - chassis) replaced Special Purpose Vehicle (SPV) types, these based on a mix of tactical and commercial truck chassis and including: water distributor, 2,000 [[gallon|US gallon]]; fuel, 1,500 US gallon; field service; [[Bitumen|asphalt]] distributor; earth [[auger (drill)|auger]]. Interchangeable commercial-off-the-shelf (COTS) - or modified COTS - bodies are fitted to MK28C chassis as field circumstances dictate.<ref name="JanesTrailers"/>

Also in 2005, Oshkosh was awarded a contract to re-manufacture an initial 27 MTVRs to new configuration and with a full new vehicle warranty.<ref name="JanesTrailers"/>

On 16 May 2008 the 10,000th MTVR was completed. By late 2011 an estimated 11,135 MTVRs had been ordered, that figure including 9,221 for the USMC and 1,855 for the Navy.<ref name="JanesTrailers"/>

In FY12 the third (and final) five-year multi-year MTVR contract was awarded to Oshkosh. The final known MTVR delivery order (US$67 m for 338 vehicles; 278 Marines, 60 Seabees) was placed in September 2012, and inclusive of this order 11,359 MTVRs were ordered by the US Marines', about 1900 of these for the Navy. Orders under the final contract could be placed until June 2016.<ref name="JanesTrailers"/><ref name="Oshkosh Medium Tactical Vehicle Replacement (MTVR), United States of America"/>

In conjunction with [[Pierce Manufacturing]] (an [[Oshkosh Corporation]] company), Oshkosh developed the MTVR MK23/25-based Hawk Extreme, a wildland firefighting water tender. This product has been sold commercially.<ref name="JanesTrailers"/>

==Technical description==
{{More citations needed section|date=January 2021}}
All production versions of the MTVR are based on the same 6×6 drive configuration<ref name="MTVR"/> and utilize a [[chassis]] constructed using bolted / [[Huck bolt|Huck-bolted]], formed channel (9.75 × 3 × 0.38 in) made of heat-treated [[Mangalloy|carbon manganese steel]] with a [[Yield (engineering)|yield strength]] of 110,000 psi minimum. The engine is located under a forward [[fiberglass|fibreglass]] [[hood (vehicle)|hood]]. The cab seats three and is of welded [[aluminium]] [[extrusion]] construction with adhesive bonded aluminium skins. The cab folds down to reduce overall height to 98 in and from mid-2007, production vehicles are armor-ready and have air-conditioning, revised cab mounts and upgraded cab suspension.<ref name="JanesTrailers"/>

With the exception of the UK's Wheeled Tanker variants, all MTVRs are powered by a [[Caterpillar Inc|Caterpillar]] C-12, Advanced Diesel Engine Management (ADEM) III 11.9-litre six-cylinder [[diesel engine]] that develops 425 [[Horsepower|hp]] at 1,800 rpm and 1,550&nbsp;ft-lb of [[torque]] at 1,200 rpm.<ref name="MTVR"/> When the [[central tire inflation system]] (CTIS) is set at 0 to 2 tons payload, engine power output is automatically reduced by around 20%.<ref name="JanesTrailers"/> Driveline is completed by an [[Allison Transmission|Allison]] HD 4070P seven-speed [[automatic transmission]], TC-541 [[torque converter]] and an Oshkosh 30000 Series single-speed [[transfer case]].<ref name="Oshkosh Medium Tactical Vehicle Replacement (MTVR), United States of America">{{cite web |url=http://www.army-technology.com/projects/oshkosh-medium-tactical-vehicle-replacement-mtvr/|title=Oshkosh Medium Tactical Vehicle Replacement (MTVR), United States of America|publisher=army-technology.com|access-date=2015-12-30}}</ref>{{Unreliable source?|reason=domain on WP:BLACKLIST|date=June 2016}} All-wheel drive is permanent and under highway driving conditions the torque split is 32% front, 68% rear.

Oshkosh TAK-4 [[Independent suspension|independent coil spring suspension]] is fitted to the MTVR,<ref name="Oshkosh MTVR Military Power">{{cite web |url=http://www.trucktrend.com/cool-trucks/0809dp-oshkosh-mtvr/|title=Oshkosh MTVR - Military Power|date=September 2008 |publisher=trucktrend.com|access-date=2015-12-23}}</ref><ref name="Advanced Suspension Technology">{{cite web |url= https://oshkoshdefense.com/technology-1/advanced-suspension-technology/|title=TAK-4|publisher=Oshkosh Defense|access-date=2016-08-05}}</ref> this providing each front wheel with a total vertical travel of 16.0 in and a travel of 12.8 in on the rear axles. The front axle is rated at 16,000&nbsp;lb, the second at 23,500&nbsp;lb, the third at 25,400&nbsp;lb. The MK36 [[Tow truck|wrecker]] and MK31 tractor variants have [[Hendrickson International|Hendrickson]] hydraulic [[Suspension (vehicle)|suspension]] on the rear [[axle]]s.

Standard tires fitted to the MTVR are [[Michelin]] 1600 R20 XZL and with the exception of the MK36 wrecker variant, no spare is carried. Compensating for no spare is a runflat setting option on the [[Central tire inflation system|CTIS]]. CTIS allows the driver to adjust tire pressures to suit both payload and terrain conditions, from the driving seat. The two-piece bolt-together steel wheel rims are fitted with [[beadlocks]] for extreme low-pressure operations and tires will remain seated at pressures down to 10 psi. In the event that any one tire should fail totally, a limp-home facility allows for a second axle suspension unit to be raised and secured.

Mobility parameters include a climatic operational range of -50&nbsp;°F to 125&nbsp;°F. The MTVR has a maximum speed of 65&nbsp;mph and on-road cruising range of 300&nbsp;mi. It can climb a 60% gradient and traverse a 40% side slope with its maximum cross-country load. It can ford 60in of water.<ref name="Oshkosh Medium Tactical Vehicle Replacement (MTVR), United States of America"/> [[Turning radius]] and [[Approach and departure angles|approach]], [[Approach and departure angles|departure]], and [[Breakover angle|ramp breakover]] angles vary by variant.

MTVR variants can be internally transported by [[C-5 Galaxy|C-5]], [[Boeing C-17 Globemaster III|C-17]] and [[C-130]] Hercules transport aircraft. The MK23 can be transported underslung by [[CH-53]] helicopter.<ref name="Oshkosh Medium Tactical Vehicle Replacement (MTVR), United States of America"/>

The original MTVR trailer was designed and developed by [[Oshkosh Corporation|Oshkosh]] to provide a matching trailer for the MTVR truck. Two prototype MTVR trailers were manufactured and tested between May 2000 and March 2001. In June 2005 the [[Marine Corps Systems Command|U.S. Marine Corps System Command]] (MARCORSYSCOM) awarded the [[Choctaw]] Manufacturing and Developing Corporation (CMDC) a $1.9 million Small Business Sole Source design and development contract for the MTVR Trailer. Oshkosh manufactures and supplies the associated trailers for the MK37 [[HIMARS]] resupply variant.<ref name="Medium Tactical Vehicle Replacement (MTVR) Trailer (MTVR-T)">{{cite web |url=http://www.globalsecurity.org/military/systems/ground/mtvr-t.htm|title=Medium Tactical Vehicle Replacement (MTVR) Trailer (MTVR-T)|publisher=globalsecurity.org|access-date=2015-12-30}}</ref>

==MTVR Armor Systems (MAS)==
Oshkosh promotes the current MTVR armor packages as the MTVR Armor Systems (MAS). The current Standard MAS with Survivability Upgrade (MAS-SU) kit is available for a variety of models. The Reducible Height MAS (MAS-RH) is also available. Installation of armor requires a vehicle front axle and cab suspension mount upgrade, plus a revision to the cab roof gun mount. [[Air-conditioning]] is also fitted. From mid-2007 all production MTVRs have been armor ready, these modifications now forming part of the standard vehicle specification.<ref name="JanesMET"/><ref name="MTVR Armor Protection Kit (APK)MTVR Armor System (MAS)">{{cite web |url=http://www.globalsecurity.org/military/systems/ground/mtvr-armor.htm|title=MTVR Armor Protection Kit (APK)MTVR Armor System (MAS)|publisher=globalsecurity.org|access-date=2015-12-31}}</ref>

Development of a protection kit for the MTVR commenced in 2003, with the first production contract awarded in 2004 and calling for 920 baseline appliqué APKs for the cab, plus 460 modular armored rear troop carrier compartments. The cab and troop carrier kits, while complementary, are separate units and can be installed as such. A follow-on contract for 930 cab kits and 465 rear troop-carrier compartments was awarded in 2005. Two further contracts for a total of 293 cab kits were awarded in 2007. Oshkosh announced in August 2008 an initial contract award for height reducible armor kits for MVTRs. Around 2400 height reducible armor kits for MVTRs have been ordered. Additional awards for armor/protection-related upgrades have been made.<ref name="JanesMET"/><ref name="MTVR Armor Protection Kit (APK)MTVR Armor System (MAS)"/>

A small arms fire and mine blast protection kit for the U.K. MoD's MTVR-fronted Wheeled Tanker fleet has been developed and fitted to vehicles used on overseas operations.<ref name="JanesMET"/>
