While modern vehicles are the backbone of contemporary military operations, the U.S. military still relies on several older trucks that have stood the test of time. These vehicles, known for their durability and versatility, continue to serve in various capacities across different branches. Let’s delve into seven classic models that remain integral to military logistics and operations.
M35 Series “Deuce and a Half”

The M35 Series, affectionately known as the “Deuce and a Half,” has been a stalwart in military operations since its introduction in the 1950s. Renowned for its ability to carry 5,000 pounds over rough terrain, the M35 was extensively used during the Vietnam War. Its multifaceted design allows it to be configured for cargo, troop transport, or even as a mobile command center. Despite being phased out by more modern vehicles, the M35 is still seen in training exercises and reserve units.
Its longevity can be attributed to its simple mechanics and robust construction. The truck’s diesel engine is relatively easy to maintain, making it an ideal choice for operations in remote areas where resources are limited.

M939 Series 5-Ton Truck

The M939 Series 5-Ton Truck has been a reliable workhorse for the U.S. military since the early 1980s. Built to replace the older M809 Series, the M939 offers improved handling and a more powerful engine. It is mainly used for transporting troops and supplies, equipped with a central tire inflation system to adapt to various terrains. The truck’s versatility is further demonstrated by its ability to be converted into a wrecking or recovery vehicle.
What sets the M939 apart is its adaptability and ease of use, which have allowed it to remain in service for decades. Its ongoing use underscores its effectiveness in both combat and humanitarian missions. For a deeper dive into the history of these vehicles, visit this detailed encyclopedia.
M809 Series 5-Ton Truck

Introduced in the late 1960s, the M809 Series 5-Ton Truck served as the backbone of military logistics for many years. Known for its ruggedness, the M809 was primarily used for hauling heavy cargo and was a key asset during the Cold War era. Its design features a multifuel engine, making it adaptable to various fuel types, a crucial advantage during extended deployments.
Despite being gradually replaced by newer models, the M809 is still in use among reserve units and in training capacities. Its straightforward mechanical design allows for easy maintenance, ensuring it remains operational even in challenging conditions. This enduring utility is discussed in various military studies, including a comprehensive analysis available on JSTOR.
M800 Series 5-Ton Truck

The M800 Series 5-Ton Truck is another classic model that has seen extensive use since its inception in the late 1960s. Known for its robustness and reliability, the M800 was designed to transport troops and supplies under harsh conditions. Its simple yet effective design has made it a favorite among mechanics, ensuring that it remains serviceable even with minimal resources.
Though overshadowed by its successors, the M800 is still operational within certain U.S. military units, particularly in non-combat roles. Its continued use is a testament to its enduring capability and reliability in various military operations.
M715 Jeep Kaiser

The M715 Jeep Kaiser, developed in the 1960s, was one of the first vehicles to bridge the gap between civilian and military utility trucks. Designed to be a general-purpose vehicle, the M715 was used extensively during the Vietnam War for transporting troops and supplies. Its rugged design made it suitable for the challenging terrains and climates encountered in Southeast Asia.
Today, the M715 is cherished by military vehicle collectors and is occasionally used in training exercises. Its historical significance and functional design make it a notable example of military vehicles used in diverse operations over the decades.
M151 MUTT (Military Utility Tactical Truck)

The M151 MUTT, or Military Utility Tactical Truck, was introduced in the late 1950s as a replacement for the legendary Willys Jeep. Known for its agility and off-road capabilities, the M151 served extensively during the Vietnam War. Its unibody construction and independent suspension provided superior handling compared to its predecessors.
Even though production ceased in the 1980s, the M151 remains in service in various training and support roles. Its design and operational history continue to influence modern military vehicle development, reflecting its lasting impact on military logistics.
M880 Series CUCV (Commercial Utility Cargo Vehicle)

The M880 Series CUCV was introduced in the 1970s as a cost-effective alternative to purely military-designed vehicles. Based on the Dodge D Series trucks, the M880 was primarily used for transport and support roles. Its commercial roots meant it was cheaper to produce and maintain, a significant advantage during budget constraints.
While officially retired, the M880 still sees limited use in non-combat roles within the military. Its legacy lives on as a precursor to modern military vehicles that blend commercial and military technologies.
