The 37 mm gun motor carriage M6, also known as M6 Fargo, and under the manufacturer (Dodge)'s designation WC55, was a modified Dodge WC52 light truck mounting a light anti-tank gun. It was used by the United States Army for infantry support and as a mobile anti-tank gun. It operated from late 1942 to January 1945 in the Mediterranean, European, and Pacific theaters of World War II. The M6 saw limited use during the war, and was poorly suited to modern warfare as it was unarmored and was armed with a too small caliber gun. Being required to back into firing positions rather than forward firing proved to be a deficiency.

M6 WC-55 top schematic

The 37 mm GMC M6 was a modified 3/4-ton 4x4 Dodge WC52 truck with a rear-facing 37 mm M3 gun mounted in its bed ( portee ) and designated WC55. The gun was normally fired to the rear – it could not be fully depressed when pointed to the front of the vehicle due to blast effects on the crew and vehicle windshield. The gun fired M74 Armor Piercing (AP) Shot that could penetrate 1.4 in (3.6 cm) of armor at 500 yd (460 m). Other ammunition carried throughout its service life included the Armor Piercing Capped (APC) M51 Projectile (which could penetrate 2.4 in (6.1 cm) of armor at 500 yd), and the High Explosive (HE) M63 Projectile. Eighty rounds of 37 mm ammunition were carried aboard. [1]

The crew-members were equipped with personal weapons for self-defense.

Second Army Tennessee Maneuvers – to increase firepower, a 50 cal. machine gun was mounted on the front of the 37 mm gun truck (June 1943).

With the design standardized in February 1942, 5,380 GMC 37 mm M6 GMC were built between April and October, 1942, at a cost of $4,265 per unit. [2] American doctrine planned for tank destroyers to defeat enemy tank attacks while tank units proper carried out offensive duties. The 37 mm GMC M6 saw limited employment with U.S. forces (the 601st and 701st Tank Destroyer Battalions) during the campaign in Tunisia in late 1942 and early 1943. The vehicle was not well liked because it lacked armor and carried an anti-tank gun that was largely ineffective against German tanks of the period. The 37 mm GMC M6 also saw limited use in the Pacific Theater in 1943 and 1944. [3] They equipped some Marine units, but were withdrawn before seeing combat. The 37 mm GMC M6 was soon classified as "limited standard" in September 1943, because of the availability of more powerful tank destroyers mounting 75 mm (2.95 in) and 3 in (76 mm) guns. In January 1945, the GMC M6 was declared obsolete.

After the Tunisian campaign, many M6 Fargos had their 37 mm gun removed and reverted to a cargo truck role as the WC52. Some of these 37 mm guns were mounted onto halftracks to provide the armored infantry with a gun halftrack. [4] Other 37 mm GMC M6 vehicles found their way into service with the French Army, and were later provided to French Forces of the Interior units after the liberation of France. [5] Despite the vehicle's obvious limitations on the battlefields of Northwest Europe 1944–1945, the FFI used practically any vehicle they could obtain because of equipment shortages of all kinds.

A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities.

The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman.

The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US-pattern turrets were called "Lee", named after Confederate general Robert E. Lee, while those with British-pattern turrets were known as "Grant", named after Union general Ulysses S. Grant.

<span class="mw-page-title-main">Anti-tank gun</span> Form of artillery

An anti-tank gun is a form of artillery designed to destroy tanks and other armoured fighting vehicles, normally from a static defensive position. The development of specialized anti-tank munitions and anti-tank guns was prompted by the appearance of tanks during World War I. To destroy hostile tanks, artillerymen often used field guns depressed to fire directly at their targets, but this practice expended too much valuable ammunition and was of increasingly limited effectiveness as tank armor became thicker. The first dedicated anti-tank artillery began appearing in the 1920s, and by World War II was a common appearance in many European armies. To penetrate armor, they fired specialized ammunition from longer barrels to achieve a higher muzzle velocity than field guns. Most anti-tank guns were developed in the 1930s as improvements in tanks were noted, and nearly every major arms manufacturer produced one type or another.

<span class="mw-page-title-main">M36 tank destroyer</span> Self-propelled anti-tank gun

The M36 tank destroyer, formally 90 mm Gun Motor Carriage, M36, was an American tank destroyer used during World War II. The M36 combined the hull of the M10 tank destroyer, which used the M4 Sherman's reliable chassis and drivetrain combined with sloped armor, and a new turret mounting the 90 mm gun M3. Conceived in 1943, the M36 first served in combat in Europe in October 1944, where it partially replaced the M10 tank destroyer. It also saw use in the Korean War, where it was able to defeat any of the Soviet tanks used in that conflict. Some were supplied to South Korea as part of the Military Assistance Program and served for years, as did re-engined examples found in Yugoslavia, which operated into the 1990s. Two remained in service with the Republic of China Army at least until 2001.

The M18 Hellcat is a tank destroyer used by the United States Army in World War II and the Korean War. Despite being equipped with the same main gun as some variants of the much larger Sherman tank, the M18 attained a much higher top speed of up to 55 mph (89 km/h) by keeping armor to a minimum, and using the innovative Torqmatic automatic transmission.

<span class="mw-page-title-main">M10 tank destroyer</span> WW2 American tank destroyer

The M10 tank destroyer, formally 3-inch Gun Motor Carriage M10, or M10 GMC was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942 and delivered in April that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1942 as the "3-inch Gun Motor Carriage M10". It mounted the 3-inch gun M7 in a rotating turret on a modified M4 Sherman tank chassis.

It uses long projectiles that are more powerful than its caliber suggests. The T-12 served as the primary towed anti-tank artillery in the Soviet and Bulgarian armies from the early 1960s to the late 1980s.

The 37 mm gun M3 is the first dedicated anti-tank gun fielded by United States forces in numbers. Introduced in 1940, it became the standard anti-tank gun of the U.S. infantry with its size enabling it to be pulled by a jeep. However, the continuing improvement of German tanks quickly rendered the 37 mm ineffective and, by 1943, it was being gradually replaced in the European and Mediterranean theaters by the more powerful British-developed 57 mm gun M1. In the Pacific, where the Japanese tank threat was less significant, the M3 remained in service until the end of the war, but some 57mm guns were issued.

<span class="mw-page-title-main">Tank destroyer battalion (United States)</span> Type of unit used by the United States Army during World War II

The tank destroyer battalion was a type of military unit used by the United States Army during World War II. The unit was organized in one of two different forms—a towed battalion equipped with anti-tank guns, or a mechanized battalion equipped with armored self-propelled guns. The tank destroyer units were formed in response to the German use of massed formations of armored vehicles units early in WWII. The tank destroyer concept envisioned the battalions acting as independent units that would respond at high speed to large enemy tank attacks. In this role, they would be attached in groups or brigades to corps or armies. In practice, they were usually individually attached to infantry divisions. Over one hundred battalions were formed, of which more than half saw combat service. The force was disbanded shortly after the end of the war when the concept had been shown to be militarily unsound.

The T23 armored car was an entry from the Fargo Division Chrysler for a new fast tank destroyer to replace the M6 37mm gun motor carriage in July 1941 initiated by the U.S. Army Ordnance Department. Required specification was to be able to withstand fire from a .50 in (12.7 mm) machine gun to the front and side from a .30 in (7.62 mm) machine gun. Although Dwight D. Eisenhower's headquarters were in favor, the design was rejected in favor of the Ford T22.
