Medium Tank M3 Lee/Grant

United States of America (1941-1942)
Medium Tank – 6,258 Built

A Lend-Lease stopgap tank

The Lee/Grant never achieved the fame of the Sherman. This was due to its very roots and the role it played during the war. Born as a replacement for the unsuccessful M2 Medium Tank (1938), which never left the American soil, the M3 was designed and equipped in a rush. When war broke out in Europe in 1939, the USA was far from ready to enter the fray. Its tank design was evolving through a peacetime, post-crisis context, and tactical thinking was inherited from WWI. 400 tanks were available then, mostly Light Tank M2 models.

Hello dear reader! This article is in need of some care and attention and may contain errors or inaccuracies. If you spot anything out of place, please let us know!

The result of the blitzkrieg in France came as a real surprise and immediately triggered a complete re-thinking of US tank design. Shortly after the battle of Britain was over, war engulfed North Africa. The British industry was not able to deliver enough tanks to defend both the homeland and the empire, and notably its vital crossing points, like the Suez Canal. As the Lend-Lease act was passed, on March 11, 1941, President Roosevelt famously declared that the USA should become the “arsenal of democracy“. And the M3 Lee quickly turned into its most tangible symbol.

Design of the M3 – The “Iron cathedral”

The M3 design process began in July 1940, as a derivative of the T5 Medium Tank prototype, the T5E2. By then, the M4 Sherman, a 75 mm (2.95 in) armed medium tank, was already scheduled for production. But many features, like the full rotating turret design, were far from ready and the US industrial capacity not mature enough for the required production values. The T5E2 design came as an interim, fast-to-production model.

The rushed design then entered production, being required both by US Army needs and the United Kingdom’s demand for 3,650 medium tanks (by then a British proposal for US-built Crusaders and Matilda was rejected). It was basically a scaled up M2, with better armor, a much higher and wider hull, in order to mount an offset 75 mm (2.95 in) gun in a traversable sponson on the right side.

The initial plans called for a full traverse turret equipped with a single AA cal.30 (7.62 mm). The 75 mm (2.95 in) was meant to deal both with static ground targets and other tanks, with its armor-piercing projectiles and good velocity. High explosive shells were carried as well. However, the 37 mm (1.46 in) gun was still favored in the AT role, and one was added in a small turret on top of the superstructure.

An upper cupola was initially designed to house a cal.30 (7.62 mm) machine-gun, giving this model its cartoonish, caricatural appearance, bristling with guns in turrets and sponsons, much like a battleship. As customary for US tanks by that time, secondary armament comprised between three and eight cal.30 (7.62 mm) model 1919 machine-guns. The tracks, most of the suspension system, road wheels and return rollers were all borrowed from the M2 to ease production. The main difference was a three bogie train and redesigned suspension.


An M3A1 Lee (cast, smooth hull model). These models seem to have been too costly to be built en masse at the time. Progress would be made preceding the start of M4 production. The advantage of a cast hull was, of course, the theoretical time-saving assembly and less added material, meaning less weight. Both M3A2 and M3A3 reverted back to a welded, sharp angled hull.

Large and roomy, the M3 accommodated a large transmission unit, running through the crew compartment. It was served by a synchromesh, 5 speeds forward, 1 reverse gearbox, and steering was obtained by differential braking. The vertical volute suspension incorporated a self-contained return roller, which was no longer fixed to the hull. This feature was meant for easier maintenance and repair. The turret was geared by an electro-hydraulic system, powered by the main engine, also providing pressure for the main gun stabilizer, and the turret could make a full traverse in less than 15 seconds.
The main gun was operated by a loader and gunner (with a spade grip) and targeting done through an M1 telescope, mounted right on the sponson roof.

The maximum range was 2700 m (3000 yds). An M2 telescope served the secondary gun, which had a maximum range of 1400 m (1500 yds). This 37 mm (1.46 in) gun was operated with geared handwheels for traverse and elevation. The normal provision was 46 rounds for the 75 mm (2.95 in), 178 for the 37 mm (1.46 in) and 9200 for the machine-guns. The maximal configuration included machine guns mounted in the upper turret, lower coaxial, commander cupola, rear external AA mount for a single M1919 A4, and even four hull machine-guns in sponsons, fitted in the four corners of the superstructure. In practice, they were rarely seen.

The powerplant was an aircraft based Wright Continental, with high-octane gasoline, air cooled, which was also a perfect choice for a speedy production, as no dedicated engine powerful enough was available then. The upwards position of the transmission, not helped by the tall engine, which sat high on the rear part of the hull, forced the entire casemate to be raised. The overall design was incredibly tall, 10 feet (3 m) high, which later arose as its major drawback on the battlefield. The Germans nicknamed the M3 a “splendid target” and the Americans the “iron cathedral”.

The British order

The M3 was not the initial choice of the British commission. The wooden mock-up was built when the first plans were ready and presented in 1940. Several flaws immediately appeared, among them, a high profile, sponson gun, riveted hull, insufficient armor and a hull mounted radio. But as production was scheduled to start quickly after the final prototype was ready, and hoping for improvements on later versions, an initial order for 1250 M3s was placed for a total 240 million dollars, and the production shared between three US companies, Pressed Steel Car, Pullman, and Baldwin. These three built the British models (soon called “Grant”, after the famous Union general), while the US models (called “Lee”, after his famous confederate antagonist) were produced by the Chrysler Detroit Tank Arsenal, and American Locomotive (ALCO) at Schenectady, New York.

The turrets were cast by Union, General Steel Casting, ASF and Continental. This explains why there were so many differing details within the two main versions -M3 and M3A1- and between the British and US models. The British prototype was ready in March 1941. It included a distinctive turret back bustle to accommodate a Wireless Set No. 19 radio, stronger armor and no machine-gun cupola, replaced by a simple hatch. The armor increase was not initially planned but introduced as soon as new reports of German anti-tank capabilities were available. The initial crew included a driver, commander, gunner and loader, upper gunner, a machine-gun servant and a radio operator. The British model didn’t include the radio operator. Later, the US crew numbers were also reduced to six and even five in 1942, as one of the gunners became the radio operator.

Production from the M3A1 to the M3A5

Ready as it was for mass-production, 4724 units M3s were built in the first batch, starting from mid-1941, and the second batch of 1334 units was built until December 1942, encompassing the M3A1 to the M3A5 versions. The M3A1 (Lee II) featured a cast rounded hull, with a low profile turret and slightly thicker armor. Only 300 M3A1s were built, followed by the M3A2 (Lee III), with a welded but sharp angled hull, of which only 12 units were produced. The M3A3 (also called Lee IV and V), featured a welded hull, a pair of GM 6-71 diesels, and fixed or eliminated side doors (322 units).

The M3A4 (Lee VI) had a stretched welded hull and a new Chrysler A57 multibank engine, a strange assembly of five 6-cyl L-head car engines mated to a common crankshaft, boasting a final 21 liters capacity with 470 bhp and a lot of torque. This was well-appreciated, as the initial model was criticized for being under-powered. Only 109 of these M3A4 were built. The last production (591 units), mostly fielded by the British army, was the M3A5, equipped with the twin GM 6-71 diesels, but with a riveted hull and Lee turret. Strangely, they were called “Grant II” in British service. Due to the many contractors involved, notably the cast turret foundries, these variants showed further variety in the shape of the hull, turret and details, notably due to different casting procedures.

M3 variants

The M3, as a basis for further developments, was incredibly successful. Not only did it allow the long-awaited M4 Sherman to be designed and produced faster, thanks to the many parts it shared with the M3, but the same chassis also served for other vehicles.
These included the Canadian Ram tank, the 105 mm (4.13 in) Howitzer Motor Carriage M7, better known as the M7 Priest, 155 mm (6.1 in) Gun Motor Carriage M12, the Kangaroo armored personnel carrier, and the Sexton Mk.I self-propelled gun.

Many were also converted as recovery tanks, the model M31 (also called Grant ARV in British service), and the M31B1 and M31B2, based, respectively, on M3A3/A5 versions. The M31 was fitted with a dummy gun and turret, a crane and a towing apparatus with a 27 ton (60,000 lb) winch installed. The M33 Prime Mover was a conversion of former towing versions as artillery tractors (109 units in 1943-44).
The British variants were the Grant ARV, an armored recovery vehicle obtained from disarmed Grants Mk.Is and Mk.IIs, the Grant Command, equipped with map table, extra radio, and dummy guns; the Grant Scorpion III, a mine-cleaning vehicle equipped with the Scorpion III flail, and its variant the Scorpion IV; and eventually the Grant CDL, which stands for “Canal Defence Light”, featuring a powerful searchlight and a machine gun. 355 were produced in all, which were also registered in US army service as the “Shop tractor T10”. A single Australian conversion (800 had been transferred by 1942) was the BARV, a beach recovery vehicle, which used the M3 chassis. Probably the last of these versions was the Australian Yeramba Self Propelled Gun, with 12 units adapted from the M3A5 in 1949.

The M3 in action

With a production running only one year and a half and an obsolete, awkward design, the M3 was not supposed to be a frontline tank during the entire length of the conflict. But it nevertheless saw service until the very end, thanks to some qualities, redeployment in more suitable campaign theaters, and conversions to other duties.
The British, although reluctant, pushed for it since it was the only model suitable for instant mass-production, and it became the warhorse of the British VIIIth Army during 1941-42, especially during the worst period of the campaign. Although the high silhouette and main gun position were despised, the Lee/Grant was reliable, very sturdy, had good armor and, overall, generous firepower. Through Lend-Lease, 2,855 units were sold to the British and 1396 were supplied to the USSR.

The British M3 in combat

First engagement came with the disastrous battle of Gazala, which did not diminish the role played by these tanks (at that time, the main British design, the Crusader, only had a 40 mm gun and minimal armor). Grants and Lees were well-used in each major engagement of the African campaign, from El Alamein to the end of the Tunisian campaign, in mid-1943. By then, upgunned Panzer IIIs and IVs proved deadly and the M3 had been gradually replaced by more capable Shermans and British designs armed with the QF 6 pounder.
Since there were battle reports of the M3 throughout mid-1942 to November, when the first US forces arrived in Africa, most variants (A1 to A5) were attributed to British requirements. British M3s were sent to the India/Burma theater as soon as they received the new M4 Sherman. About 1700 transferred units gave an excellent account of themselves during all the campaign, from 1943 to 1945. 800 were taken over by Australian forces, and 900 by Indian forces. They formed the bulk of the Fourteenth Army (with Indian crews), with battle honors such as the fall of Rangoon, the battle of Imphal (proving pivotal in their task), were they battered out the Imperial Japanese Army’s 14th Tank Regiment.

The US Army M3 in combat

The baptism of fire of the US Army M3 came during operation Torch, under light opposition from Vichy French forces, but they were more heavily tested during the race for Tunis in December, and the battle of Kasserine Pass. By then, only one operational unit was equipped with M3s, the 2/13th Armored Regiment of the 1st Armored Division. The last surviving units had been replaced by M4s at the beginning of 1943.
Ironically, many depleted units equipped with M4 were reequipped with M3s, notably the 3/13th Armored regiment. The other unit entirely equipped with M3s was the 751st Tank Battalion of the 34th Infantry Division. By the time of Operation Husky (campaign of Sicily), the M3 was still in use by these units, but once again, the losses were replaced by M4s, and by mid-1943, all M3s in this sector had been phased out from active units.

In the Pacific theater, a single unit equipped with M3s, the 193rd Tank Battalion, deployed its M3A5s fitted with wading gear in Butaritari, part of the Makin atoll (Gilberts Islands), in November 1943, for infantry support against pillboxes and the rare Japanese light tanks encountered. None were ever used by the US Marine Corps. In March 1944, US army ordnance declared the M3 obsolete. Most M3s were converted for other uses, cannibalized for spare parts, affected to drilling center units. For its odd-looking appearance, the M3 was shown in movies like 1943’s “Sahara”, starring Humphrey Bogart, and in its remake in 1992, and in 1979 in Spielberg’s “1941”. Perhaps 50 have survived until today in various museums and private collections, including a dozen in running conditions.

The Soviet M3s in combat

Part of the Lend-Lease plan, a shipment of 1300+ M3s were delivered by convoy to Murmansk and put in operational use by Soviet armored brigades, notably around Leningrad and Stalingrad. The tanks were designated as the M3S, the S standing for Sredniy, meaning Medium. For a long time it was believed the tanks sent to the Soviet Union were M3A3 and A5 Diesel powered sub-variants. But recently found documents suggest that all M3s sent to the USSR were the standard model, fitted with the Continental radial engine.

The Soviets quickly realized this model was not a winner and, after one year of hard fighting realised it was hopelessly outdated. Surviving vehicles (infamously called “A grave for Seven Brothers”) were retired from front-line operations and shipped to quieter or less well-defended sectors, like the Arctic front. There, they took part in the Lista and Petsamo-Kirkenes offensives, where they encountered second-rate German tanks, mostly former French captured models. Some M3s were also captured by the Wehrmacht in 1942 and served as the Panzerkampfwagen M3(r).
The Soviets also recieved 130 M31 Tank Recovery Vehicles, based on the hull of the M3. Some of these were the M31B1 Diesel powered variant.

Operation Bertram

Another way of hiding your tank, besides camouflage, was to change its shape. This type of deception tactic had been used by the Royal Navy in WW1. They changed the outline of destroyers to look more like merchant ships. When the WW1 German U-boat surfaced to attack the ship with its main gun the screens would drop to enable a full broadside of high explosive shells to be fired at the submarine. These type of ships were called ‘Q’ boats.
During Operation Bertram, in the months leading up to the second Battle of El Alamein in North Africa in September – October 1942, camouflage and dummy vehicles were used to deceive the Germans where the next attack was going to come from. Real tanks were disguised as trucks, using light “Sunshield” canopies. To achieve the deception, trucks were parked openly in the tank assembly area for some weeks. Real tanks were similarly parked openly, far behind the front. Two nights before the attack, the tanks replaced the trucks, being covered with “Sunshields” before dawn.

Operation Bertrum M3 Grant tank
The tanks were replaced that same night with dummies in their original positions, so the armour remained seemingly two or more days’ journey behind the front line. Interviews with captured German senior officers showed that this type of deception was successful: they believed the attack was going to come from the south where they had seen the dummy tanks and vehicles and not in the north. The idea for the Sunshield came from Commander-in-Chief Middle East, General Wavell.

Operation Bertrum M3 Grant tank with Sunshield Lorry camo
The first heavy wooden prototype was made in 1941 by Jasper Maskelyne, who gave it the name Sunshield. 12 men were needed to lift it. The Mark 2 Sunshield was made of canvas stretched over a light steel tube frame. On 11th November 1942, Prime Minister Winston Churchill announced victory at El Alamein in the House of Common.
During his speech, he praised the success of Operation Bertram, “

By a marvelous system of camouflage, complete tactical surprise was achieved in the desert. The 10th Corps, which he had seen from the air exercising fifty miles in the rear, moved silently away in the night, but leaving an exact simulacrum of its tanks where it had been, and proceeded to its points of attack.” (Winston Churchill, 1942)

I have a photo of a Lee M3 serving with British 25th Dragoons in the Arakan, Burma, in 1944 with its crew in front. It is a small b & w print but if you would like a copy please send your email address

The 13th Armored, known as the Black Cats, landed at Le Havre, France, 29 January 1945. They were never in Tunisia.

Hello Scott,
Thanks for the message. Unfortunately, you are confusing the 13th Armored Division, which indeed landed in France in 1945 and never fought in North Africa, and the 13th Armored Regiment, which did saw service in Tunisia.

The US Marine Corporation builds small fiberglass boats in Wisconsin. I believe you meant the U.S. Marine Corps.

Hello
If the T3 ARV (Armored Recovery Vehicle) is part of the Free French 2nd Armored Division, it is under General Leclerc and it lands in Normandy.
General De Lattre de Tassigny leads the First Army landing in Provence. The 1st Armored Division belongs to the First Army.
Great site, continue the fine work.

It can’t be reversed if you look when they show the inside the gun is on the left seat in the center, but that does not matter. When the guy puts his gand in the track to the left almost of the screen if you would “unreverse” the video how would he be standing. It’s his right hand no matter what, so would he face the tanks forward, or like, that means it’s a M3 with the main gun in a left sponson.

I think he means to sat that the video has been mirrored, not ‘reversed’. This is a simple way of getting around the copyright of the original film/image.

There is in Brasil in São Gonçalo city, rio de janeiro State one M3A2 in the ex-combatentes square. It dont have the motor and the tower and suspension system is broken. It is painted in olive drab. The m2 canon and de 38mm are fixed.

In the WW 2 movie Sahara, Humphrey bogart stated that his tank Lulubelle was part of American tanks lend-lease to british units to gain experience. If this is correct what unit would have the M3 tanks attached to it. the movie is pretty good and some great tank scenes check it out I think you’ll enjoy it.

The Soviet M3 tanks used in Finland in 1944 were salvaged from a wreck in 1942. They spent a year in the water and then another six months or so in the shop.
I haven’t seen any other references after the battle of Kursk, so outside of that odd ball case, the stock of M3 Mediums were probably used up in the summer of 43.

About “M3S, 241st Armored Brigade, Stalingrad sector, October 1942” graphic picture.
“Заводы рабочимъ!” (Plants for workers) is old Russian variant which used before Russian Revolution. It is impossible to see that variant in 1940s, because in that time a modern Russian was in using: “Заводы рабочим!” (without “ъ” on the end).

Tank crew reduced to five? Okay, my understanding is the US Lee started with a crew of 7 (Commander, Driver, Radio Operator, 37mm Gunner, 37mm Loader, 75mm Gunner, 75mm Loader). This was reduced to 6 when the Radio Operator was eliminated and his duties fell to the driver. Here, I read that a gunner took over the radio to reduce the crew to five. Why? So, you could eliminate the Driver? How do you eliminate the Driver? If the crew was reduced to 5 late in the war. Which position was eliminated?
Note: British Grant tanks (another version of the Lee) had the radio moved to the turret so the commander had direct access, and therefor no radio operator .. different scheme to get a crew of 6.

In 1995, the movie “Sahara” was updated with James Belushi replacing Humphrey Bogart. The original movie is always preferable.
The early U.S. tanks of W.W. -2 were produced with overwhelming quantities versus German quality.
Today, the M-1 Abraham’s Tank is seemingly unmatched, overwhelming the Russian Tanks in quality over quantity. It’s fascinating to watch the change in tactics and production over time. Clearly, (for good or bad motives) the U.S. has proven the German philosophy of providing it’s military with smaller numbers of tanks with an overwhelming technological advantage. “Combined Arms” seems to be the trend for the foreseeable future.

The German philosophy of tanks and tank production was significantly flawed.
German tanks were technologically advanced in some opinions, but others comment on how they were over-engineered and difficult to build and maintain, as well as operate.
Germany had too many different kinds of tanks and not enough of each one. Again this made maintenance and production hard.
American tanks had some technological advances that most German tanks lacked. Powered turrets, “wet” stowage of ammo, high velocity armor piercing rounds (better than Germany’s but that is my opinion), discarding sabot rounds, etc.
Trying to maintain complex building standards in a wartime industry that was being continuously bombed was difficult. In fact the lack of certain materials like molybdenum meant the later German armor was compromised, to the point that it actually shattered when hit.
Germany had some very good and very feared tanks. But the successes they did have were also in part due to other factors. One was the armor philosophy of certain American Generals who believed the tank’s role was infantry support, not tank on tank engagements. Thus the persistence of lower velocity 75mm guns and delayed development and delivery of heavy tanks like the Pershing. As noted in the very well researched book Armored Thunderbolt, the single greatest determining factor of the winner of a tank in a tank fight was who got off the first shot. This was almost always the defender, and since Germany was typically in this position they came out on top. This was reversed in the Battle of the Bulge where American tanks, and particularly tank destroyers, got off the first shots as defenders and wreaked havoc on even the best German tanks.
Despite individual tanks being better, one would be hard pressed to find a large number of multi-tank engagements, battles, and campaigns that Germany won over the U.S.
Yes American tanks are the highest tech and best tanks in the world right now. But in my opinion this was not due to the adoption of a WWII German tank philosophy.

As has been noted in an earlier reply, British Cruiser Tanks—the A9, A10, A13, and Crusader, were fit with the Ordnance Quick Fire 2-Pdr. The metric bore of the 2-Pdr was 40mm/L50, although this measurement was not employed by the Royal Army.

This is a serious technical error, and should be corrected.

Just watched the program Lost Evidence battle of El Alamein near the end of the program it showed a Grant tank with the gun on the left hand side, this is the third different program with different grant tanks showing the gun on the left hand side one of the film clips shows another grant behind it with the gun on the right hand sidey

That must have been some mirrored footage, all Grants had the gun on the right side of the tank.

Just a random thought as to whether the M3 Lee named “Jack Sharkey” in the illustrated section shouldn’t be called the “Shiloh” instead (with “Jack Sharkey” being the name of the main gun). “Shiloh” was the first great battle in the western theater during the American Civil War, and was nearly a Southern victory before timely Union reinforcements turned it into a Southern defeat (hence, enthusiasts on both sides seem rather fond of claiming that battle). Jack Sharkey, as you probably know, was an American heavy weight boxer who briefly held the world title (winning it from a German fighter, no less). He was also the only boxer to have ever fought both Jack Dempsey and Joe Louis (he lost both matches). Wikipedia says he visited the U.S. troops in North Africa during the war, so there may even be a direct personal reference to the use of his name. The fact that the M3’s main gun was mounted on the right-hand side may also have added to the boxing symbolism–“a good right hook,” etc. Just a thought. Thanks for building such a great website on tanks. My great uncle was in the 13th Armored Regiment, 1st Armored Division. He was killed in action in a tank the day before Rome was liberated and is buried in the Sicily-Rome American Cemetery (so very very far from his native Kentucky).

Sorry to nit pick, but I feel a better way of wording that would be “were supplied to Australia”.

My understanding was the the M3s used in Australia were supplied new and direct from the US. I assume they were the tail end of the UK order. Australia had grand plans at one stage to raise and deploy an Armoured Division for fighting in the Western Desert and the development and production of the AC-1 was the intended vehicle.

The AC-1 production was made redundant when US build equipment became more readily available and while the division was raised, the change to a more Pacific focus meant it was never deployed as a division.

The M3 is relatively common in Australian armour museums. At Keswick in South Australia there is one that was converted post war as a mobile camera bunker for use in the various missile tests being done in the desert.

So I was looking at reddit and found this image of a m3 lee (don’t think it’s a grant) with the hull gun replace with a QF 17 pounder and the upper turret removed. There are 2 photos of this tank I could find and was wondering if there is any record of this being used or recorded. Thx

I’m a model-maker. One of my friends who is also a model-maker, sent me photos of his artwork of this vehicle made for his client. The client told him that this is M3 ‘Lancer’, and sent me an article, which is obviously unreliable. And those were photos of collection from Pakistan Lahore Museum for I found videos of it on YouTube . But I haven’t found introduction of this vehicle. I will keep looking for that.

Do you have technical information on the elevation & traverse limits of the 75mm Gun in the sponson ?

Hi Gary,

Highest vertical angle – 19 degrees
Lowest vertical angle – 8 degrees
Horizontal firing angle – 32 degrees

This data is from a publication titled: The Firing Tables for 75mm M2 Tank Gun in the Medium American Tank M3 (Published in 1942). A primary source on the matter.

I’m sure this has probably been suggested, but this tank encyclopedia should be turned into a multi-volume book encyclopedia (and don’t hold off on the drawings and photographs. You’d make a fortune and it’d be worth it.

Very informative and extensively researched. So quick question, I noticed that most variants that have an additional .30 Caliber machine mounted in the turret either have it mounted under the 76mm or to the right. I have a scale model with it mounted to the left of the main gun. Is my model just an inaccurate model or was this a potential variant?
Thanks in advance.
