The M4 Sherman tank was produced in several variants, a result of mass production spread across several manufacturers and several years. It was also the basis for a number of related vehicles and Shermans have been modified by several nations, ranging from upgrades to complete hull conversions for another task. Originally designed in 1941, M4 variants were still used by Israel during the 1967 and 1973 wars with its Arab neighbors. [1]
The many special duties that a tank might be made to do were just being explored by armies around the world in the early 1940s. Theories of what vehicles were supposed to be engaging enemy tanks changed as vehicles like the Sherman often found themselves up against enemy armor, and consequently some of the most important initial changes centered around up-gunning the basic vehicle. Improving the vehicle's mobility, protection, and creating specific variants for infantry-support roles soon followed. Similar modification of the main armament would be done by the British, who received a number of Shermans through Lend-Lease during the course of the war, producing the Sherman Firefly tank (armed with a powerful 17-pounder tank gun).
Many early variants of the Sherman were converted to armored personnel carriers (called "Kangaroos") or armoured recovery vehicles.
In preparation for the invasion of Europe by Allied forces in 1944, an amphibious "swimming" version of the Sherman was used. Extensive work on creating mine-clearance devices to be attached to Shermans in some fashion was also conducted up until the end of the Second World War, such as the Sherman Crab mine-flail tank.
After the Second World War, large numbers of surplus Shermans were supplied to other nations, most primarily to Africa, South America and the Middle East. Israel became the largest post-war user of Sherman tanks, conducting extensive modifications to keep them in frontline service right up into the early 1970s as tanks, mobile artillery pieces, armored ambulances and many more versions. Many saw action in the 1967 Six-Day War and 1973 October War. Similar modifications and purchases of Israeli-modified Shermans were done in South America where they served on as the last fighting Shermans right up until 1989.
There are many variants of the Sherman, ranging from the M4, M4A1, M4A2, M4A3 and M4A4, which also encompass many sub-variants (such as the M4 (105) or M4A3E8 "Easy Eight", among others).
Over the course of production a number of improvements in the design were introduced. The turret of T20/T23 prototypes with its 76mm gun was adapted to the Sherman and entered production in February 1944; M4 variants with this armament had the suffix "76mm" added to their designations. The use of the 105mm howitzer for equipping close support tanks occurred from 1943. In reaction to fires following penetrating hits, applique armor was added to the outside of the hull. This was followed by internal modification with "wet stowage" jacketing the ammunition racks. Suspension was changed by the use of the stronger HVSS from mid-1944. HVSS had twice the number of wheels per bogie and individual wheels could be replaced without removing the bogie from the hull. Tracks were wider and vehicles had track covers that extended beyond the hull. Other hull modifications included a 47 degree angled glacis for simpler production, larger access hatches and a hatch for the loader and commander's cupola. [2]
Variants without the M4 designation but built on the M4 medium chassis (While some began on the M3 chassis, some subvariants were switched to the M4 chassis during production. These are the models listed here):
Experimental
90mm Gun Motor Carriage T53/T53E1 – 90mm gun mounted on M4A4 chassis. Design modified for dual anti-tank and anti-aircraft use as T53E1 with outriggers for stability. Order for 500 cancelled in 1944 after design rejected by both Tank Destroyer and AA branch of US Army. [7]
Rocket-firing, flame-thrower, mine-clearing, amphibious, engineer; mostly experimental (indicated by T instead of M).
The M4 Sherman series were widely distributed to allied armies under the Lend-Lease program. Variants served in all theaters, and were the basis of a number of conversions for various uses, including armored personnel carriers and specialized engineering vehicles.
The M4 Sherman pattern enjoyed a lengthy post-war service all over the world. They were used well into the 1960s and 1970s by some nations, mainly in Africa and Latin America. In some cases, the vehicles were converted for use in a variety of other roles from mobile artillery to ambulances. Conversions were also made for use in civilian industry.
There were two common civilian industrial conversions in Canada. The Finning Corporation introduced a shortened chassis with a powerful hydraulic rock drill, which was able to navigate very rough terrain for road construction. [10] The Madill Corporation found a ready market for a range of logging equipment using converted Sherman chassis. Perhaps the most spectacular were spar yarders with an extensible mast with various winches and cables to haul heavy logs up steep slopes. [11]
A military engineering vehicle is a vehicle built for construction work or for the transportation of combat engineers on the battlefield. These vehicles may be modified civilian equipment or purpose-built military vehicles. The first appearance of such vehicles coincided with the appearance of the first tanks, these vehicles were modified Mark V tanks for bridging and mine clearance. Modern military engineering vehicles are expected to fulfill numerous roles such as; bulldozer, crane, grader, excavator, dump truck, breaching vehicle, bridging vehicle, military ferry, amphibious crossing vehicle, and combat engineer section carrier.
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 Stuart/light tank M3, was an American light tank of World War II. An improved version of the tank entered service as the M5 in 1942 to be supplied to British and other Commonwealth forces under lend-lease prior to the entry of the U.S. into the war. Afterwards, it was used by U.S. and Allied forces until the end of the war.
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.
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.
An armoured recovery vehicle (ARV) is typically a powerful tank or armoured personnel carrier (APC) chassis modified for use during combat for military vehicle recovery (towing) or repair of battle-damaged, stuck, and/or inoperable armoured fighting vehicles, such as tanks and armoured personnel carriers. Most ARVs have motorized tracks, like a tank or bulldozer, enabling the ARV to operate on uneven ground. The term "armoured repair and recovery vehicle" (ARRV) is also used.
The 155 mm gun motor carriage M12 was a U.S. self-propelled gun developed during the Second World War. It mounted a 155 mm gun derived from the French Canon de 155mm GPF field gun.
The Sherman M-50 and the Sherman M-51, both often referred to abroad as the Super Sherman, were modified versions of the American M4 Sherman tank that served with the Israel Defense Forces from the mid-1950s to early 1980s. The M-51 was also referred to as the Isherman. However, the nicknames "Super Sherman" and "Isherman" were never officially used by the Israeli Defense Forces.
The 155 mm gun motor carriage M40 was an American self-propelled artillery vehicle built on a widened and lengthened Medium Tank M4A3 chassis, but with a Continental engine and with HVSS, which was introduced at the end of the Second World War.
This article deals with Sherman tanks extensive use around the world after World War II and catalogues foreign post–World War II use and conversions of Sherman tanks and variants based on the Sherman chassis.
The medium tank T20, medium tank T22 and medium tank T23 were prototype medium tanks, developed by the United States Army during World War II. They were designed as successors to the M4 Sherman. The standard main weapon for production versions of these designs was to be the 76 mm gun M1.
The United States provided tens of thousands of its Medium Tank M4, also named the Sherman, to many of its Allies during the Second World War, under the terms of Lend-Lease.
The 76 mm gun M1 was an American World War II–era tank gun developed by the U.S United States Ordnance Department in 1942 to supplement the 75 mm gun on the basic Medium tank M4. It was also used to arm the M18 Hellcat tank destroyer.
The 75 mm howitzer motor carriage M8 was a self-propelled howitzer vehicle of the United States in use during World War II. It was developed on the chassis of the M5 Stuart tank and was equipped with a M116 howitzer in an M7 mount. The vehicle is also known by the nickname General Scott, or just Scott, which was originally assigned to the vehicle by the Ordnance Department in November 1944 for publicity purposes, such as in newspapers, but does not appear to have been used by troops in the field during the war.
The United States has produced tanks since their inception in World War I, up until the present day. While there were several American experiments in tank design, the first American tanks to see service were copies of French light tanks and a joint heavy tank design with the United Kingdom.
The M32 tank recovery vehicle was an armored recovery vehicle (ARV) used during World War II and the Korean War by the United States, and was based on the chassis of the M4 Sherman medium tank. During World War II, the British also used several hundred M32s, which were obtained through lend-lease in 1944. The first four prototypes were produced in January 1943, labeled T5, T5E1, T5E2, T5E3, and T5E4. After a series of tests at the Aberdeen Proving Grounds, the prototypes were approved as M32, M32E1, M32E2, M32E3, and M32E4. However, the M32E4 never entered production. There were also variants that had horizontal volute spring suspension (HVSS), which were demarcated by the suffix "A1" after the model number.
