Front cover G1 1930

This is the Group G series List of the United States military vehicles by (Ordnance) supply catalog designation, – one of the alpha-numeric "standard nomenclature lists" (SNL) that were part of the overall list of the United States Army weapons by supply catalog designation, a supply catalog that was used by the United States Army Ordnance Department / Ordnance Corps as part of the Ordnance Provision System, from about the mid-1920s to about 1958.

In this, the Group G series numbers were designated to represent "tank / automotive materiel" – the various military vehicles and directly related materiel. These designations represent vehicles, modules, parts, and catalogs for supply and repair purposes. There can be numerous volumes, changes, and updates under each designation. The Group G list itself is also included, being numbered G-1.

Generally, the G-series codes tended to group together "families" of vehicles that were similar in terms of their engine, transmission, drive train, and chassis, but have external differences. The body style and function of the vehicles within the same G-number may vary greatly.

Group G scope

[edit]

The July 1943 Ordnance Publications for Supply Index (OPSI); page 68) sums up in detail, the coverage of Group G as:

"Armored, half-track, and scout cars; gun, howitzer, and mortar motor carriages; cargo, mortar, personnel, half-track and universal carriers; armored amphibian, light, medium, and heavy tanks; light, medium, heavy, crane and amphibian/track-type tractors; wheeled tractors; armored, bomb, heavy-duty and tractor crane trailers; tank recovery and tank transporter trailer trucks, with their parts and equipment. Ordnance maintenance bomb service, emergency repair, machine shop and repair trucks, with their parts and equipment. Prime movers, passenger cars, fuel tank trucks, fuel and water tank trailers, and semitrailers; trucks, with stake, platform, dump, and special bodies; amphibian cargo and personnel trucks; motorcycles and side cars." [1]

No numbers in the G-400 to G-499 range were ever used.

List of the United States military vehicles by supply catalog designation

View on Grokipedia
from Grokipedia
The List of vehicles by supply catalog designation is a historical index of U.S. Army ground vehicles, organized according to the Standard Nomenclature List (SNL) system employed by the Ordnance Department, with Group G designations specifically assigned to tanks, trucks, and other automotive for purposes of identification, procurement, maintenance, and logistics support. This alpha-numeric coding, typically formatted as "G-" followed by a number (e.g., G-503 for certain 1/4-ton trucks), formed part of a broader catalog structure that included multiple volumes detailing spare parts, technical specifications, and related equipment, enabling standardized supply management across operations. Developed during World War II, the SNL Group G system played a crucial role in supporting major campaigns, including the Normandy invasion in 1944—where it helped achieve 61% of planned supply delivery by D+15 despite logistical challenges—and extended into the Korean War for efficient inventory control and readiness enhancement. The designations encompassed a diverse array of vehicles, from light utility trucks and amphibious models to heavy cargo carriers and armored units produced by manufacturers like GMC, , and , reflecting the era's emphasis on rapid mobilization and repair. By facilitating the tracking of over 6 million parts (though only about 26% fully cataloged), the system reduced waste, such as through programs that cut excess stockage by over 80% between 1969 and 1972, and supported annual per-item costs of approximately $200 under the evolving Federal Stock Number framework. The SNL designations were phased out following the 1962 Department of Defense reorganization under Secretary McNamara, which shifted to a more centralized, industry-reliant model and introduced Federal Stock Numbers (FSN) in 1949, later evolving into the National Stock Number (NSN) system still in use today. Despite this transition, Group G listings remain a valuable historical reference for understanding mid-20th-century U.S. military logistics.

Introduction to the System

Overview of Supply Catalog Designations

The Standard Nomenclature List (SNL) system, implemented by the U.S. Army Ordnance Corps, served as a comprehensive cataloging framework for standardizing the supply, repair, and inventory of military beginning in the mid-1920s. This system assigned unique identifiers to equipment and parts, ensuring consistent across the Army's network to facilitate , distribution, and operations. By providing detailed descriptions, including names, numbers, and illustrations of spare parts, the SNL enabled efficient tracking of over 350,000 components associated with approximately 1,860 equipment models, supporting field services and reducing logistical errors. The SNL employed an alpha-numeric designation structure, where letters from A to Z denoted broad categories of , and numeric suffixes specified individual items or subcomponents within those groups. This organization was integral to the Ordnance Provision , promoting interchangeability of parts and streamlining inventory management across depots and units. For instance, encompassed such as , while Group D covered pieces, illustrating how the system categorized diverse equipment for uniform identification without overlap. In the broader context of , the SNL's role extended to supporting technical publications and supply catalogs, which were regularly updated to incorporate new developments and classifications. Group G, for example, addressed and automotive , further demonstrating the system's capacity to handle specialized categories within the overall framework.

Historical Context and Usage

The supply catalog system for U.S. military vehicles originated in the as a response to the severe logistical challenges faced during , including shortages of spare parts and difficulties in vehicle maintenance for the . Influenced by British supply practices observed in , the U.S. Ordnance established the Field Service Division in to manage surplus wartime supplies valued at over $1.3 billion, and issued the Ordnance Provision System Regulations and Provisional Manual in 1920 to standardize nomenclature and grouping of items. This framework, building on interwar efforts like the National Defense Act of 1920, aimed to create efficient stock control and procurement processes through arsenals and district offices, incorporating commercial cataloging techniques from companies such as Roebuck. The system's usage peaked during , when it became essential for coordinating the massive scale of vehicle production and supply chain logistics under the Ordnance Department. As industrial mobilization accelerated, the catalog facilitated the procurement of over 3 million vehicles—including more than 600,000 jeeps—and supported the distribution of tens of millions of spare parts monthly to sustain combat operations across multiple theaters. Group G designations played a key role in categorizing automotive vehicles during this period, enabling decentralized district offices and government-owned, contractor-operated plants to meet surging demands outlined in the Army Supply Program from 1942 to 1944. A document was the Ordnance Publications for Supply Index (OPSI), which detailed the structure of supply groups and their scopes to guide , , and field reference for ordnance items. This index, part of the broader Standard Nomenclature Lists (SNLs) introduced in 1928, ensured uniformity in describing vehicles and components across the . The supply catalog system was phased out around 1958, replaced by the Federal Supply Classification (FSC) and eventual National Stock Number (NSN) systems under the Federal Catalog System established by the Federal Property and Administrative Services Act of 1949, to modernize logistics across federal agencies. Throughout its operational history, the system markedly improved military efficiency by minimizing errors and delays via standardized , fostering between units and suppliers during critical wartime expansions.

Structure of Group G Designations

Group G serves as the dedicated designation within the Army's Ordnance Supply Catalog for and automotive , covering a broad array of , modular assemblies, individual components, and supporting catalogs essential for and . This grouping facilitates the systematic identification and of items critical to ground mobility, from engines and transmissions to complete tracked or wheeled platforms, ensuring across Army units during operations. The structure emphasizes functional categorization to streamline , particularly in wartime environments where rapid part replacement was vital. The core numbering scheme for Group G spans from G-1 to G-999 and extends beyond as needed, with organization by vehicle type and purpose rather than strict separation of components from complete vehicles. Designations like G-1 cover major vehicles and combinations (e.g., bomb service trucks and maintenance vehicles), while others such as G-503 designate specific models like the 1/4-ton 4x4 command reconnaissance truck (also applicable to the Ford GPW variant). This approach supports precise , with each number serving as a in Standard Nomenclature Lists (SNL). Subgrouping within Group G prioritizes engineering similarities over superficial traits, classifying items by intrinsic features such as , transmission mechanisms, layouts, and frameworks to promote modularity and ease of repair. For example, vehicles sharing a common or suspension system might fall under adjacent designations, regardless of body style or armament, fostering in a diverse fleet. This principle is exemplified in notation conventions like G-503, which designates the 1/4-ton 4x4 command reconnaissance truck (also applicable to the Ford GPW variant), where the associated SNL G-503 document delineates parts into functional subgroups—such as Group 01 for the engine assembly (including and pistons), Group 06 for electrical components (like generators and regulators), and Group 07 for the transmission—complete with exploded diagrams, stock numbers, and interchangeability notes for variants. The numbering system's evolution originated in early World War II efforts under the Ordnance Department, with initial assignments formalized through directives like Circular 121 in , which standardized catalog prefixes and groupings to address surging production needs. Gaps were intentionally incorporated during this period to reserve space for anticipated developments or experimental models, leading to relatively sparse population in higher ranges (e.g., beyond G-700) by war's end. This forward-looking design, refined via War Department Circular 304 in 1944, ensured adaptability while minimizing disruptions in supply documentation.

Scope of Group G

Included Vehicle Types

Group G of the military supply catalog designations encompasses a wide array of ground-based vehicles and related equipment essential for combat and logistical operations. This group focuses on providing mobility on land, including primary combat vehicles and supporting transport systems, while explicitly excluding and to delineate its scope to terrestrial applications. Primary vehicle types under Group G include armored cars, which provide and security with protective plating; tanks categorized by weight classes such as light, medium, and heavy for varying roles; semi-armored cars offering partial protection for utility functions; and full-tracked vehicles designed for superior cross-country performance in rough terrain. Half-tracked vehicles represent a hybrid category, combining the stability of tracks with the maneuverability of wheels, often functioning as both truck-like carriers and units for towing or supplies. Support vehicles in this group comprise tractors in light, medium, and heavy variants for pulling loads; trailers such as models and specialized tank transporters; trucks ranging from 1/4-ton scouts to 10-ton heavy haulers for troop and material movement; motorcycles for rapid dispatch; and amphibious vehicles capable of operating on both land and water surfaces to facilitate river crossings or coastal maneuvers. These elements ensure comprehensive logistical support, enabling the sustainment of frontline forces through efficient transport of personnel, , and . Ancillary items covered include gun motor carriages, which mount on mobile platforms for support; self-propelled mounts for weapons integration on vehicles; and essential components like , engines, and suspensions that form the foundational structure and power systems for all listed vehicles. Overall, Group G emphasizes ground mobility tailored for combat effectiveness and logistical reliability, with its designations remaining in use through 1958 for cataloging these assets. As summarized in the July 1943 Ordnance Publications for Supply Index (OPSI), Group G covers: "Armored, , and scout cars; gun, howitzer, and mortar motor carriages; tractors; trucks; and trailers."

Organizational Principles

The organizational principles of Group G designations in the United States supply catalog system emphasize functional grouping to enhance supply efficiency and logistical support for automotive and tank materiel. Vehicles sharing , such as those within the same engine family or chassis design (e.g., common axles across Chevrolet and GMC truck models), are assigned to shared designation blocks, allowing for streamlined , , and parts distribution across similar platforms. This approach minimizes redundancy in by categorizing components as peculiar (unique to a model), (usable across variants), or common (standard across multiple vehicles), thereby facilitating rapid repairs in field conditions. A hierarchical structure governs the assignment of designations within Group G. Variants are distinguished through letter suffixes, enabling precise identification of incremental changes without disrupting the core numbering scheme. This hierarchy supports a modular approach, where subassemblies can be referenced independently for repairs or upgrades. Cross-referencing integrates Group G with other catalog groups for comprehensive support, linking vehicle platforms to accessories or armaments in Groups A (small arms) or F (fire control), while Group G retains primary ownership of the core vehicle structures like tanks and trucks. Each Group G designation is directly tied to Standard Nomenclature List (SNL) booklets, which serve as the primary documentation for parts identification, exploded diagrams, and maintenance procedures. These SNLs, published as Ordnance Supply Catalog supplements (e.g., ORD 7 for organizational spares, ORD 9 for complete parts lists), ensure standardized and include detailed illustrations for assembly hierarchies, supporting echelon-based repairs from field units to depot levels.

Period of Application and Limitations

The Group G supply catalog designations for United States military vehicles were actively applied primarily from World War II until 1958, with the majority of assignments concentrated during the 1940s to support rapid procurement and standardization of tank and automotive matériel. In the late 1950s, the system transitioned to the Federal Supply Classification (FSC) and National Stock Number (NSN) frameworks under the Defense Cataloging and Standardization Act of 1952, which formalized an 11-digit Federal Stock Number (FSN) in 1949 and rendered Group G obsolete for new vehicle cataloging by integrating it into a unified Department of Defense inventory system. Known limitations of the Group G system include numerous unassigned or undocumented higher designations, attributable to incomplete records, multiple overlapping numbering schemes, and the challenges of wartime production diversity that hindered full standardization. As of 2025, Group G coverage excludes all vehicles developed after 1958 due to the NSN's adoption, which expanded to a 13-digit format in 1974, while documentation for experimental prototypes remains sparse owing to their provisional status and limited production runs. Archival sources for Group G, including Ordnance Supply Index (OSI) references and Standard Nomenclature List (SNL) documents, are accessible via repositories like Archive.org, though some records from the interwar and early postwar periods have been lost to time or remain classified for security reasons.

Vehicle Designations by Range

G-1 to G-99

The G-1 to G-99 range in the supply catalog designations represents the initial segment of Group G, focusing on early experimental and automotive from the and the early stages of . These designations primarily encompassed tracked tractors for artillery towing, light tanks for reconnaissance, and initial designs, reflecting the U.S. Army's efforts to develop mobile ground support capabilities before the shift to large-scale manufacturing. Group G's emphasis on shared drivetrains across vehicle types allowed for modular upgrades in propulsion systems, facilitating rapid adaptation in limited production runs. The G-2 designation was assigned to the M1917 5-ton , a tracked vehicle manufactured by the and standardized as the U.S. Army's first such design for heavy artillery towing during . Powered by a 4-cylinder OHV producing 56 horsepower, it achieved a top road speed of approximately 7 mph and could tow loads up to 10 tons across rough terrain, with approximately 3,480 units produced, many serving in . The G-39 designation applied to the M2 light tank series, including variants M2, M2A1, M2A2, and M2A3, developed in the 1930s at as an infantry support and reconnaissance platform. Weighing approximately 7.5 short tons (6.8 metric tons) in combat configuration, early variants mounted .30- and .50-caliber machine guns, with the subsequent M2A4 adding a 37 mm main gun in a rotating turret; powered by a 250-horsepower Continental W-670 engine for a top speed of 36 mph; though not deployed in combat, around 375 units of the early series were built for training purposes leading into . The G-87 designation corresponded to the M2 half-track truck (also known as the M2 half-track car), introduced in 1941 as the U.S. Army's first standardized half-track for personnel transport and light artillery towing. This 9-metric-ton vehicle combined front-wheel drive with rear tracks for enhanced cross-country mobility, accommodating up to 10 troops or a 37 mm gun, and was powered by a 128-horsepower White 160AX engine; over 15,900 M2/M2A1 units were produced, serving as a foundational design for subsequent half-track variants. The G-99 designation was given to the M5 tractor crane, a light tracked vehicle built by on the TD-9 tractor chassis with a Trackson CT-9 swing crane attachment, primarily for and recovery tasks in forward areas. Rated for 2-ton lifts and weighing about 13 tons, it featured a 4-cylinder and was produced in limited numbers (approximately 343 units for the crane variant) starting in 1943, mainly for U.S. Navy and use in construction and maintenance roles.

G-100 to G-199

The G-100 to G-199 range within the U.S. Army Ordnance supply catalog system primarily encompassed designations for heavy tractors, experimental medium tanks, and specialized maintenance trucks essential to II-era logistics and field support operations. These vehicles emphasized durability and versatility in combat environments, with many incorporating standardized components for efficient supply chain management. Heavy tractors in this group were crawler-type machines optimized for towing artillery, while maintenance trucks utilized the proven 6x6 drivetrain for mobility across varied terrain. Designations were organized partly by engine compatibility to streamline parts interchangeability and maintenance. The G-101 designation applied to the M1 heavy tractor, a crawler model produced by the International Harvester Company based on the TD-18 commercial design. Powered by a 6-cylinder delivering approximately 100 horsepower, it was intended for hauling heavy pieces like the 155 mm over rough ground, with a drawbar pull exceeding 20,000 pounds. Adopted in 1940, the M1 heavy tractor weighed about 25,000 pounds and featured wide tracks for low ground pressure, making it suitable for and ordnance units; production continued through the war with variants adapted from civilian models for military standardization. G-137 designated the , an experimental armored vehicle developed by as a potential successor to light tanks like the . Originally conceived in 1941 as the T7 light tank but redesigned for medium classification, it mounted a 75 mm M3 gun in a three-man turret on a hull derived from the T5 medium tank prototype, with and armor up to 50 mm thick; weighing 24.5 metric tons (27 short tons), it achieved speeds of 35 mph. 13 prototypes were built between April and September 1942 before cancellation in favor of the , due to overlapping capabilities and production priorities. Designations G-138 through G-149 covered a series of 2.5-ton, 6x6 ordnance maintenance trucks built on the GMC CCKW chassis, which became a cornerstone of U.S. mobile repair operations during . These variants were equipped with specialized bodies for on-site repairs, powered by the GMC 270 cubic-inch inline-6 gasoline engine producing 95 horsepower, and featured Timken drive axles for all-wheel capability in mud or snow. Over 500,000 CCKW trucks were produced from 1941 to 1945, with maintenance models comprising a significant portion for divisional ordnance companies.

These maintenance trucks played a critical role in sustaining armored and units by enabling rapid repairs close to lines, reducing downtime and enhancing operational tempo in theaters like and the Pacific.

G-200 to G-299

The G-200 to G-299 range in the U.S. military supply catalog designations primarily covered niche vehicles and trailers developed during for specialized roles, such as environmental adaptation and fire control support in . These designations were assigned under the Standard Nomenclature List (SNL) system, which organized ordnance items by functional groups, with Group G focusing on combat and tactical vehicles including tractors and towed equipment. Limited production characterized this series, as many items remained prototypes or saw low-volume output due to shifting wartime priorities and the rapid evolution of operational needs by 1944–1945. Examples include the G-220 M22 director trailer and G-231 T36 snow tractor, alongside other trailers like the G-206 for Mack NO truck adaptations. The T36 snow tractor, designated SNL G-231, represented an early effort to adapt technology for and snow-covered terrains. Manufactured by the Iron Fireman Manufacturing Company under Army Ordnance contract W-42000-ORD-483, production ran from July 1944 to February 1945 at a total value of $518,000. Designed for a 3-man crew, the T36 featured enclosed tracks housing the engine for protection against extreme cold, skid steering for maneuverability, and a capacity of approximately 7,500 pounds for cargo or towing sleds. It achieved speeds up to 34 km/h on snow and was tested as early as 1942 for potential use in northern supply routes and search operations by the Army Air Forces. Only 36 units were completed, reflecting its status as a prototype-focused adaptation with limited field deployment before the war's conclusion. Within the same series, the M22 director trailer, designated SNL G-220, served as a mobile platform for fire control equipment in anti-aircraft and setups. This 2-ton, 4-wheel trailer with a hard-top enclosure was built by manufacturers including Fruehauf and designed to transport and mount director units for coordinating fire, particularly in multiple .50-caliber systems like the M16 carriage. It included provisions for electrical integration and stabilization during operations, enabling rapid setup in forward areas. Detailed specifications and maintenance procedures were outlined in War Department Technical Manual TM 9-881, which covered director trailers including the M22 alongside related generator and mount trailers. Production emphasized durability for towed use behind standard trucks, but quantities remained low, prioritizing integration into experimental anti-aircraft batteries rather than mass issuance. These designations highlighted the U.S. Army's exploration of environmental and tactical innovations during WWII, with the G-200 series often involving prototypes for harsh conditions or precise control needs. Many such vehicles saw testing but minimal adoption, as postwar curtailed further development.

G-300 to G-399

The G-300 to G-399 range within the Ordnance supply catalog designations covers post-World War II developments in armored vehicles, emphasizing gun launchers, medium tanks, and light armored cars designed to counter evolving Soviet armored threats during the . This era marked a shift toward upgraded and mobility to address limitations exposed in Korea and anticipated in potential European conflicts, with many numbers left unassigned due to selective and experimental projects. Significant gaps, such as G-317 to G-335 and G-337 to G-352, highlight the incomplete utilization of this block, as the Army prioritized specific upgrades over comprehensive cataloging. Note: Post-1958, Federal Stock Numbers largely replaced SNL G-designations. G-336 designates the M60A1E2 gun launcher, an experimental variant developed in the late 1960s to integrate missile technology into conventional tank design. Built on the M60A1 chassis, it featured a compact, fully stabilized turret mounting a 152mm gun launcher capable of firing both high-explosive rounds and the wire-guided anti-tank missile, enhancing standoff engagement capabilities against armored targets. Additional upgrades included improved systems, enhanced ballistic protection, and command features, with the vehicle weighing approximately 52 tons and offering a cruising range of approximately 280 miles. Service testing occurred at , , in 1972, reflecting efforts to modernize the M60 series amid tensions. Further along, G-355 corresponds to the M48A5 tank, a mid-1960s upgrade of the to extend its viability against improved enemy armor. This variant paired the reliable M48A1 hull with the M60 tank's turret and a 105mm M68 main gun, providing greater penetration and accuracy over the original 90mm armament while retaining the Continental AVDS-1790 engine for a top speed of 30 mph and operational range of 280 miles. Weighing around 49 tons with sloped cast armor up to 110mm thick, the M48A5 served through the , supporting operations in rugged terrain and demonstrating the Army's strategy of incremental enhancements to legacy platforms. The range concludes with sparse assignments, including G-392 for the M706 armored car, a versatile 4x4 light armored vehicle introduced in 1963 by Cadillac Gage (later ) for , , and escort roles. Powered by a V8 engine producing 202 horsepower, it achieved speeds up to 65 mph with a range of 400 miles, featuring amphibious capability, a modular turret for .50-caliber machine guns or 20mm cannons, and aluminum armor protecting against small arms and fragments. Deployed to in 1968, the M706 excelled in securing supply routes over vulnerable highways, where its mobility and low silhouette addressed shortages of dedicated armored assets; lessons from the conflict recommended maintaining sufficient stocks to avoid improvised hardening of standard trucks, which compromised payload efficiency. Over 3,000 were produced in the V-100 family, with service extending into the 1980s for and rapid-response duties.

G-400 to G-499

The G-400 to G-499 range in the Group G supply catalog designations for military was entirely unassigned and unused, as evidenced by the absence of any corresponding entries in key historical records. The Ordnance Publications for Supply Index (OPSI), which served as the comprehensive guide to Ordnance publications and lists, contains no references to designations within this block for armored , trucks, trailers, or related parts. Similarly, subsequent Standard Nomenclature Lists (SNLs) for Group G, which cataloged motor and accessories from the through the era, omitted this range entirely, confirming its non-utilization across the system's lifespan. This unallocated block appears to have been reserved for potential future expansions in vehicle nomenclature, such as additional categories for emerging automotive or tracked designs, but these plans did not come to fruition due to the broader evolution of supply cataloging practices. The SNL system, including Group G for tanks, tractors, trucks, and trailers, was phased out in with the adoption of the Federal Stock Number (FSN) system, which introduced a more standardized, 11-digit coding structure for all military items to improve and efficiency. The shift to FSN addressed limitations in the older group-based designations, rendering reserved ranges like G-400 to G-499 obsolete before assignment. The unused status of G-400 to G-499 underscores administrative gaps in the early-to-mid-20th-century , where not all potential slots were filled despite the rapid proliferation of vehicle types during . No vehicles, components, or tool sets were ever cataloged under these numbers, reflecting a deliberate but ultimately redundant provisioning for growth that the war's demands and reforms bypassed. This vacancy highlights the provisional nature of the SNL framework, designed for flexibility but constrained by the need for quick amid wartime production surges exceeding 600,000 units for items like the ¼-ton 4x4 alone.

G-500 to G-599

The G-500 to G-599 designations in the U.S. Ordnance Corps' supply catalog encompassed a series of light to medium utility trucks and command vehicles primarily developed and produced during , emphasizing mobility, versatility, and logistical support for frontline operations. These vehicles were standardized under Group G for wheeled motor , with assignments in this range focusing on 1/4-ton jeeps and 1.5- to 2.5-ton cargo and command trucks that facilitated troop movement, supply delivery, and command functions across diverse terrains. Their design prioritized rugged 4x4 or 6x6 drivetrains, open or semi-enclosed cabs, and modular bodies to adapt to roles in , personnel , and light cargo hauling, becoming iconic components of U.S. from 1941 to 1945. Among the most prominent in this range was the G-503, designated for the Truck, 1/4-ton, 4x4, Command Reconnaissance, encompassing the and Ford GPW models, commonly known as the WWII . The featured a 60-horsepower "Go-Devil" inline-four engine, a three-speed with , and a capacity of 800 pounds, enabling it to tow light artillery or serve as a scout vehicle with a top speed of 65 mph. Produced from 1941 to 1945, Willys-Overland manufactured 359,849 MB units, while Ford produced 277,896 GPW variants under license, sharing nearly identical specifications including a 80-inch and foldable for low-profile operations. These jeeps were universally adopted for their compact size (119 inches long) and off-road capability, supporting over 80% of U.S. Army divisional transport needs in theaters like and the Pacific. The G-507 designation covered the Dodge WC-62 and WC-63 command and trucks, part of the T214 series 1.5-ton 6x6 vehicles designed for weapons carrier and personnel roles. Equipped with a 76-horsepower inline-six , four-speed transmission, and a 123-inch , the WC-62 lacked a front and carried up to 12 troops or 3,000 pounds of , while the WC-63 variant included a 7,500-pound for recovery tasks, both achieving 45 mph on roads. Production totaled 43,278 units between 1942 and 1945 at 's plant, with the extended flatbed and stake sides allowing modular configurations for mounts or radio equipment in command setups. These trucks enhanced divisional mobility by bridging light duties and heavier , often operating in convoys to sustain advances. Similarly, the G-508 applied to the GMC CCKW 2.5-ton 6x6 , a cornerstone of medium with variants like the CCKW-352 (long ) and CCKW-353 (short ).

These designations facilitated standardized and maintenance during the war, emphasizing versatility for in diverse theaters, from European battlefields to Pacific islands. Semitrailers like the G-600 supported bulk of supplies such as chemicals or general , while light trucks such as the G-612 provided reliable 4x2 for personnel and movement. Scooters under this series, including the G-672, offered lightweight alternatives for quick or delivery tasks, often integrated with attachments to enhance support roles without overburdening primary truck fleets. The G-600 semitrailer was a 7.5-ton low-platform model optimized for behind medium-duty tractors, featuring a flatbed measuring approximately 133 square feet that could operate without a for flexible loading of oversized or chemical containers. Produced by manufacturers including Fruehauf and Trailer Co., it prioritized low-bed clearance for stability on rough terrain and ease of attachment to 4x4 or 6x6 prime movers, making it essential for sustaining forward supply lines during amphibious assaults and inland advances. Its cargo-focused utility allowed for rapid unloading via ramps, underscoring the era's emphasis on modular vehicles that complemented heavier trailers in the G-series. In contrast, the G-612 designation covered Chevrolet's 1/2-ton 4x2 variants, such as the Model 3105 panel delivery and Model 3106 , powered by a six-cylinder with a 16- capacity, achieving a range of 176 miles at 11 miles per . These trucks accommodated up to five personnel, including the crew, and were configured for general or with enclosed bodies for weather protection, serving in ordnance maintenance and base support roles across WWII campaigns. Their civilian-derived , adapted for military use, highlighted the rapid conversion of commercial designs to meet wartime demands for economical, road-oriented utility. The G-672 represented the Cushman three-wheel motor scooter (Model 39), a compact vehicle for light delivery and airfield duties, equipped with a two-cylinder Model 340 engine providing up to 60 mph top speed and a 147-mile range on 3.5 gallons of at 42 miles per gallon. Weighing under 400 pounds, it featured a front-mounted cargo box for tools or small supplies, enabling units or ground crews to navigate congested areas efficiently, often with utility attachments like trailers for added payload. Though not fully airborne like later models, its rugged, fuel-efficient design supported rapid resupply in forward areas, with over 5,000 units produced for U.S. forces by 1945.

G-700 to G-799

The G-700 to G-799 range in the Ordnance Corps Supply Catalog encompassed designations for medium-duty tactical trucks developed primarily in the early to support Cold War-era operations. These vehicles represented a transitional generation, bridging the gap between World War II-era designs and more modern standardized series, with an emphasis on enhanced off-road capability, durability, and versatility for cargo transport, troop movement, and recovery tasks in diverse environments. Assigned during a period when the sought to modernize its fleet post-Korea, these designations were part of the broader G-series , which concluded new assignments by 1958 as nomenclature shifted toward model-specific identifiers. Note: Later vehicles like the M151 used FSN/NSN post-phase-out. The G-742 designation covered the M34/M35/M36 family of 2.5-ton 6x6 cargo trucks, commonly known as the "Deuce and a Half," produced from 1950 to 1988 by manufacturers including REO Motors (a division of ) and later . Designed as a successor to the World War II GMC CCKW 2.5-ton truck, the M35 series featured a multi-fuel Continental LDT-465-1C producing 145 horsepower, a 6x6 for improved cross-country performance, and a payload capacity of up to 5,000 pounds off-road or 10,000 pounds on highways. Introduced in 1951, these trucks saw extensive service in the for supply lines, logistics from 1965 onward, and various U.S. operations into the 1980s, with some variants remaining in use through the 1990s; over 30,000 units were built, including cargo, dump, wrecker, and van configurations. Under G-744 fell the M39 series of 5-ton 6x6 trucks, a heavy tactical family manufactured starting in 1951 by , , and others, intended to replace wartime 5-ton models like the and G-518. The baseline M54 cargo variant, powered by a 6-cylinder DFXB3 engine delivering 130 horsepower, offered a 10,000-pound off-road (doubling to 20,000 pounds on roads) and was adaptable for tractor, wrecker (M62), and dump (M56) roles, supporting artillery towing and engineering tasks. Deployed widely in the 1950s and 1960s for sustainment, the series evolved into the M809 updates by 1969 and remained in service through the 1980s, emphasizing compatibility and robust chassis for global theaters. The M151 series of 1/4-ton 4x4 utility trucks, dubbed the Military Utility Tactical Truck (MUTT), developed by from 1959 to 1982 as a direct replacement for the M38 , is sometimes retrospectively referenced under late G-series like G-838. Featuring a short-wheelbase design with for better ride quality, a 71-horsepower Continental AO-4A028 engine, and a 800-pound , the M151 achieved speeds up to 65 mph and a 273-mile range, making it ideal for , command, and light in forward areas. Entering service in 1960, it was a staple in for rapid mobility, with over 100,000 units produced and exports to more than 100 countries; the M151A2 variant (1969) addressed early rollover issues with a sturdier roll bar, and the series persisted until phased out by the HMMWV in the mid-1980s.

G-800 to G-899

The G-800 to G-899 range in the United States Army's supply catalog designations, part of the broader G-series system established by the Ordnance Corps, primarily encompasses heavy-duty trucks and trailers developed or assigned in the late as the nomenclature transitioned toward Federal Stock Numbers (FSN) and eventually National Stock Numbers (NSN) by the early . This period marked a winding down of the G-series, with assignments becoming sparse and focused on specialized vehicles for cargo and equipment transport to support emerging logistics needs, such as missile systems and heavy armor deployment. The system, originating from Standard Nomenclature Lists (SNL) during , had largely been supplanted by 1958, but lingering designations like those in this range facilitated procurement and maintenance for vehicles entering service shortly thereafter. Key entries in this range highlight the shift toward more robust, multi-axle designs suited for off-road and high-payload operations. For instance, the G-852 designation was applied to the Ford M656, a 5-ton featuring an configuration powered by a producing approximately 200 horsepower. Introduced into service in 1966, the M656 was primarily utilized for transporting Pershing components, emphasizing its role in strategic mobility despite the pre-1958 origins of its G-series label, which was retained for compatibility with existing supply catalogs. Variants included , , and models, with a gross vehicle weight rating around 30,000 pounds and central tire inflation for enhanced terrain capability. Another notable assignment, G-904, corresponded to the M747 semitrailer, a low-bed heavy equipment transporter with a 60-ton capacity designed by Construction Equipment Company (Condec). This 4-axle, 16-wheel trailer, produced starting in the mid-1960s, paired with tractors like the M746 or later M911 to haul tanks, , and other oversized loads over highways and rough terrain, featuring and a gooseneck for stability. Its designation reflects the final phase of G-series application to trailers, bridging wartime-era logistics to modern heavy transport requirements before full NSN integration.

G-900 and Beyond

The G-900 and beyond range in the U.S. military supply catalog designations marks the conclusion of the for tank transporters and trucks, with assignments limited to a few late or export models as the framework became in favor of National Stock Numbers (NSNs) by the late . This sparsity reflects the transition away from the Standard Nomenclature List (SNL) , which was primarily used from through the early era, toward more modern inventory tracking methods. Only select vehicles received these high designations, often retrospectively, to catalog existing for purposes. The M621, assigned G-900, is a 2.5-ton, 6×6 cargo truck variant of the M35 series, primarily produced for export and featuring enhanced off-road capabilities such as air lockers on all axles. It served in roles like general cargo transport and was supplied to allies including Norway for tactical logistics support. Its NSN is 2320-00-920-7593, indicating its classification as a standard cargo truck within U.S. military supply inventories. The M746, designated G-903, is a 22.5-ton, 8×8 heavy equipment semitractor developed in the late 1960s as part of the joint U.S.-German HET-70 program to support the MBT-70 main battle tank project. Produced by Ward LaFrance from 1975 to 1977, it was designed to tow the M747 low-bed semitrailer for transporting tanks like the M60, with a Detroit Diesel 12V-71T engine providing 625 horsepower and a maximum load capacity of up to 60 tons when paired with the trailer. Approximately 125 units were built for U.S. Army use in Europe, with its NSN listed as 2320-00-089-7264; the vehicle entered limited service in the mid-1970s before being phased out in favor of newer systems like the M911. These designations up to G-999 and beyond encompass experimental or transitional additions, underscoring the catalog's closure amid evolving practices by the .
