US Army Tactical Truck Engines
In the late 1930s the US Army began setting requirements for custom built tactical trucks, winning designs would be built in quantity. As demand increased during WWII some standardized designs were built by other manufactures. Most trucks had gasoline (G) engines until the early 1960s, when multifuel (M) and diesel (D) engines were introduced. Since then diesel fuel has increasingly been used, the last gasoline engine vehicles were built in 1985. Most engines have been water-cooled with inline (I) cylinders, but V types (V) and opposed (O) engines have also been used. Three air-cooled engines were used in two very light trucks. Gasoline engines up to WWII were often valve in block design (L-head), during the war more overhead valve (ohv) engines were used, and after the war all new engines (except 1 F-head and 1 Overhead camshaft (ohc)) have been ohv. All diesel engines have ohv, they can be naturally aspired, supercharged (SC), or turbocharged (TC). The same engines have ...

Louis Chevrolet (1878–1941) and ousted General Motors founder William C. Durant (1861–1947) started the company on November 3, 1911 as the Chevrolet Motor Car Company.

Oshkosh M1070 Heavy Equipment Transporter
The Oshkosh M1070 is a U.S. Army tank transporter tractor unit. In current service in A0, A1, and M1300 configurations, the M1070 is coupled to a DRS Technologies M1000 semi-trailer. The primary purpose of this combination for the U.S. Army is the transport of the M1 Abrams tank. The M1300, covered in a separate sub-section, is a U.S. Army Europe-specific derivative designed to be road legal within Europe and operates with a different trailer. The M1070 is also used to transport, deploy, and evacuate armored personnel carriers, self-propelled artillery, armored bulldozers and other heavy vehicles and equipment of all types. This combination replaced the earlier Oshkosh M911 tractor unit and M747 semi-trailer. Export sales of A0 and A1 variants have been made, and derivatives of the M1070 have been produced or are available, these including the M1070F and the Global HET. History To meet a U.S. Army requirement for the transport of the M1 Abrams main battle tank (MBT) Oshkosh Tr ...

Palletized Load System
The Palletized Load System (PLS) is a truck-based logistics system that entered service in the United States Army in 1993. It performs long and short distance freight transport, unit resupply, and other missions in the tactical environment to support modernized and highly mobile combat units. It provides rapid movement of combat configured loads of ammunition and all classes of supply, shelters and intermodal containers. It is similar to systems such as the British Demountable Rack Offload and Pickup System (DROPS). History In January 1989, the United States Army Tank Automotive Command awarded prototype PLS contracts to Oshkosh Truck Corporation, the PACCAR Government Group and General Motors, Military Vehicle Operations, with each contractor to deliver nine trucks, six trailers, and 30 flatracks for prototype hardware testing which began in September 1989. Oshkosh Truck Corporation was awarded a five-year contract for PLS in September 1990, with production commencing in 1992. ...

Heavy Expanded Mobility Tactical Truck
The Heavy Expanded Mobility Tactical Truck (HEMTT) is an eight-wheel drive, diesel-powered, tactical truck. The M977 HEMTT first entered service in 1982 with the United States Army as a replacement for the M520 Goer, and since that date has remained in production for the U.S. Army and other nations. By Q2 2021, around 35,800 HEMTTs in various configurations had been produced by Oshkosh Defense through new-build contracts and around 14,000 of these had been re-manufactured. Current variants have the A4 suffix. The 10×10 Logistic Vehicle System Replacement (LVSR) is the United States Marines Corps' (USMC) equivalent to the U.S. Army's 8×8 HEMTT and 10×10 Palletized Load System (PLS). The USMC do not use the HEMTT or PLS, and the Army does not use the LVSR, but both services use a common trailer (M1076) with all three truck types. History Following the evaluation of proposals submitted by AM General, MAN, Pacific Car & Foundry (PACCAR) and Oshkosh Truck Corporation (with PAC ...

Family Of Medium Tactical Vehicles
The Family of Medium Tactical Vehicles (FMTV) is a series of military vehicles that are based on a common chassis and vary by payload and mission requirements. The FMTV is derived from the Austrian Steyr 12M18 truck, but substantially modified to meet United States Army requirements, these including a minimum 50 percent U.S. content. There were originally 17 FMTV variants—four variants in the nominal 2.5 U.S. ton payload class, designated Light Medium Tactical Vehicle (LMTV), and 13 variants with a nominal 5 U.S. ton payload rating, called Medium Tactical Vehicle (MTV). Since the first FMTVs were fielded in January 1996 the family has been expanded and the overall design enhanced considerably. The FMTV was originally manufactured by Stewart & Stevenson (1996–2006), then by Armor Holdings (2006–2007), then by what is now BAE Systems Platforms & Services until 2011. It is currently manufactured by Oshkosh Corporation. Development and production history FMTV's ori ...

In a departure from its purpose-built predecessor, the M715 was the first U.S. tactical vehicle to use primarily commercial components; the first in a series of militarized '' commercial off-the-shelf'' (COTS) vehicle procurements. Variants Aside from the basic M715 cargo/troop carrier, the M715 series included the M724 bare cab and chassis, usually combined with a contact maintenance utility tool body, M725 ambulance, and M726 telephone maintenance utility tool body variants, all -ton, 4×4.

The Willys MD, formally the M38A1 Truck, Utility: 1/4 ton, 4x4, or the G758 by its U.S. Army Standard Nomenclature supply catalog designation, was a four-wheel drive, military light utility vehicle, made by Willys and Willys Motors / Kaiser Jeep from 1952 to 1971. It was widely procured by the U.S. military from 1952 until 1957, after which U.S. purchases were reduced to the U.S. Marine Corps. The Marine version had minor differences from the units used by other branches. The MD was the first Willys jeep with a significantly restyled body, immediately recognizable by its rounded hood and fenders. It formed the basis for the civilian and commercial Jeep CJ5, built for three decades (1954–1983), and subsequent models, and called the first 'round-fendered' Jeep. Although hard doors were still not available, the soft-top could be complemented with soft side panels and little hinged doors, that consisted of a thin steel frame with cloth and plastic window.
