Description

The M4A1 Sherman is the first variant of the early-generation Medium Tank M4 (Sherman) family. The M4 Sherman medium tank, named after the great American Civil War general William T. Sherman, was one of the Allies' most iconic fighting vehicles during World War II, and one of the most famous tanks in history. However, while this historic distinction was achieved partly owing to its inherent virtues, it was also due to the sheer quantity of them supplied, which was only topped by the Soviet Union's T-34, with a staggering 50,000 units produced. During World War II, it was by far the most commonly utilized tank in the Allies. It developed into many different variants and had a long postwar service that lasted well into the Cold War. It was frequently compared to the T-34 and had the opportunity to engage several during the Korean War. The M4A1 was the first major variant to be introduced, in February 1942. The upper hull was entirely cast and rounded. The standard M4A1 variant was produced in 6,281 units until December 1943, when it was superseded by the late-generation M4A1 (76) W variant, which received a more powerful 76 mm M1 tank gun. Until March 1945, 3,396 of these improved variants were created. This tank was nearly identical to the M4 (second variant; early-generation), having the same engine, automotive systems, and weaponry. The main distinction was the cast upper hull. The upper hull was a single massive casting. This was a difficult task with the casting technique at the time and something the Germans could not have replicated since they did not possess the advanced technology and equipment required. Everything from hatches to wheels, turrets, and weapons could be swapped between the M4 and different Sherman variants.

Introduced in Update 1.45 "Steel Generals", the M4A1 supplies the U.S. Army ground forces with the first reliable medium tank capable of engaging enemies. The M4A1 is armed with a 75 mm M3 tank gun in a fully traversable turret and can fire a variety of ammunition depending on the situation. The M4A1 variant is distinguished by its cast hull construction, which results in a curved hull shape. This results in the hull's upper front armour plate having a varied slope angle throughout the upper glacis, but it also introduces various flaws. The first is in the frontal hull and side joints, which have relatively flat angles while angling the tank, and the second is the cast construction, which reduces the overall effectiveness of the frontal hull armour. The last are the view blocks at the frontal hull's top. Nevertheless, its armour is still effective against enemy fire from smaller calibre guns. The 75 mm M3 tank gun is positioned in the M34 gun mantlet with the periscope, a smaller gun mount than the future M34A1 gun mantlet in which all future 75 mm M4 Sherman variants will be installed. This reduces the general protection of the frontal turret but also presenting a slightly greater gun depression by -2° than future M34A1 mantlet.

Notes:

• Suspension wheels are 15 mm thick while bogies are 10 mm thick and tracks are 20 mm thick.
• Belly armour is 12.7 mm thick.
• A small patch on the turret front right side is thinner (50.8 mm) than the rest (76.2 mm).
• Bolt edges on the transmission housing are 101.6 mm thick.

Taking out the M4A1 Sherman is not an incredibly difficult task. Any gun with 100+ mm of penetration will go through the front plate. Panzer III users, however, would have some trouble penetrating the sloped frontal armour, even the later Panzer III models with the 50 mm KwK39 cannon. The T-34 with the L-11 cannon can also have a difficult time penetrating the front armour. Instead, use your speed and mobility to flank the Sherman, and a shot to the 38 mm thick side armour will most likely cause an ammo detonation, destroying the Sherman. If you are forced to face a Sherman head-on, aim for the flat spot around the vision blocks at the top of the front plate. They are extremely thin and upon penetration will destroy or heavily disable the Sherman.

At this rank, the difference between a stock tank and an upgraded one are quite minimal as the M4 Sherman still has adequate firepower and mobility to make a difference on the front-lines. The most notable traits would be sluggishness due to the engine and general inaccuracy over long ranges.

Focus on the survival parts, and then move on towards the M61 shot module, which will improve instant destruction upon penetration.

Ammunition

When discussing M4A1 shells, one always has to account for the fact that it's a medium tank. This means short to medium engagement range, so realistically it can benefit more from its short-range penetration figures than long-range sniping tanks would.

• M72 shot - AP - Solid shot, stock shell. Acceptable penetration, poor post-penetration damage.
• M48 shell - HE - Low-velocity shell useful against soft targets, in particular when hitting an open-topped vehicle. Harmless against any vehicle with more than 10 mm of armour.
• M61 shot - APCBC - This shell has a better penetration than the M72 thanks to its ballistic cap and a good post-penetration damage thanks to its explosive filler.
• M89 smoke shell - Useful to blind enemy vehicles that are too remote for you to disable so that you can progress towards objectives.

Usage in battles

The M4A1 Sherman is a very capable medium tank. The 75 mm M3 cannon is capable of destroying nearly all armoured targets at its own battle rating. Combined with the very fast turret traverse rate, fast reload time of 6.5 seconds and a vertical gun stabilizer, this tank is suited to an aggressive playstyle due to the M4A1's ability to react quickly and fire relatively accurately without coming to a full stop. The gun depression of -12° also makes this tank excel in hull-down positions, unlike any other tank. One must take into account its very thin side armour which comes in at 38.1 mm, meaning that anti-tank weaponry of any kind or rank will be capable of penetrating the flanks of this tank.

Beware of this tank's very poor reverse speed as it only has one reverse gear. This affects the tank's ability to play in a defensive role. In addition, this tank is very prone to an engine fire, so the FPE is a modification that should be prioritised. Also, be sure not to let the enemy get sight of the driver and radio operators hull viewports. A single decent shot, even from 20 to 30 mm guns, can easily take the M4A1 out of the fight.

When it comes to armour, it may save you from time to time, but should not be relied on. Do not angle this tank because the rounded edges of the upper frontal plate are very thin, causing any rounds to hit this area at an angle to successfully penetrate. It is advised to keep in mind that your biggest advantage is the combination of good mobility, capable gun, and decent armour.

The M4A1 Sherman plays best in an aggressive role. Firing on the move is easily achievable due to the installation of a vertical stabiliser. This stabiliser also allows the tank to perform a brake shot, which is when the tank brakes and comes to a sudden halt upon contact with an enemy, which quickly engages the stabiliser, snapping the gun to where the gunner's sight is pointed at.

The -12° of gun depression should be exploited to its maximum potential when possible by hulling down on hills or inclines in the terrain.

The tall profile of the tank is both an advantage and disadvantage. In the context of a hull down position, it is an advantage due to the M4A1 being able to angle the turret down over the crest of a hill without having to push further up the hill. The tall profile, however, does make the M4A1 more visible, with the heightened hull making the ammunition a larger target.

Noteworthy enemies at this rank are the Panzer IV F2, the T-34 variants with the F-34 cannon, and the British Churchill infantry tank. All these tanks have guns adequate enough to destroy the M4A1 in a single shot.

Though possible, uptiering the M4A1 leaves its armour significantly more vulnerable to more advanced enemy cannons which can easily overcome the upper-front-plate of the tank.

Enemies worth noting:

M4A2 / A4 - These Sherman tanks are widely used by over 3 nations that spread across both the Allied and the Axis side, so no matter which nation you play they can be quite tough to destroy in the hands of a skilled tanker. Given the rather weak penetration of your short 75 mm gun, their hull can be almost impossible to penetrate when angled, hull down or 300 m away. For a M4A4, there are 2 apparent bulges on the upper front plate, a penetration through there can guarantee a knock out most of the times. But in case the opponent covers them up or when it's an M4A2, aim for the centre area of the gun mantlet or the turret armour not shielded by the mantlet, which allows you to disable their means of retaliation. Note that their guns are equally weak against you, so wiggle around to disrupt their aim while you reload, giving you a good chance to bounce some shells.

Churchill I, Churchill III, Pz.Kpfw. Churchill - The Churchills, with their complex hulls and sturdy turrets, can be quite hard to penetrate at range. Again, manoeuvre as close to them as possible, the ideal distance being no more than 200 m. If they are angling their hull but facing their turret at you, only go for the turret. For the Mk I Churchills, aim at the near-vertical part of their rounded cheeks to ensure successful penetrations. For the Mk III and the German Churchill, also aim for their flat turret which is at most 89 mm. The shell should go in easily and knock out most, if not all of the crew. Only when you are facing their hull without any angles should you shoot the hull, otherwise shoot the turret only, as their big tracks can easily get in front of the frontal hull. The side hull have multiple layers of armour, some of which are weirdly angled and can absorb plenty of shells.

Pz.IV F2/G/H/J - The historical nemesis of any Sherman, the Panzer IV is one of the Sherman's biggest threats at this rank. The long barrel 75 mm gun will easily penetrate the Sherman from the front. The F2 variant is admittedly easy to deal with. A single APCBC to its hull or turret should end it pretty quickly, even at long range. The other variants are slightly harder to deal with. They have thicker hull armour, at 80 mm, which will be much harder to penetrate with the APCBC over 500 m. Luckily the turret armour remains the same at 50 mm, so aim at the turret if at longer ranges.

StuG III F/G - Another historical nemesis of the Sherman, and another big threat. The StuG III packs the same punch as the Panzer IV line with its long barrel 75 mm gun, whilst losing the turret, which turns out to be both an advantage and a disadvantage. Lacking a turret means that it will have to traverse the whole vehicle to target an enemy, but it also means that it has a lower profile. The StuG's armour profile is also more complex than the Panzer IV, with less flat areas. Certain areas are sloped and very bouncy. Luckily, there is a big weak spot. There are two flat plates on the front of the hull. The flat plate on the right is the drivers port. Shoot that and you are able to knock out the driver, gunner and loader in one go. This is a very efficient way to destroy this vehicle. With the F variant, you can use APCBC to instantly knock out this vehicle with a single shot. With the G variant, it is more reliable to use AP at ranges within 500 m to ensure penetration.

R3 T20 FA-HS - This speedy wheeled vehicle can circle around you with ease and wipe out all your crew with its fast firing 20 mm autocannon. Watch out for your gun barrel, as the R3 can easily destroy it. In a close encounter, never expose your side to it, as the 20 mm will shred through the thin 38 mm plate and detonate your ammo. However, a good thing is that you can rely on your .50 cal to destroy the R3.

Pros and cons

Pros:

• Good 75 mm gun, with adequate damage and a decent rate of fire
• Frontal glacis offers good armour at its rank and tend to make rounds ricochet
• Very fast turret traverse speed
• Thick gun mantlet, and overall very good sloped turret armour
• Very strong when in a hull down position
• Excellent gun depression -12 degrees
• Very mobile once acceleration kicks in
• Pintle-mounted HMG provides an anti-aircraft defence and can shoot down lightly armoured targets
• Fitted with a vertical stabilizer, allowing more accurate fire on the move compared to other tanks, as well as better usage of shoot-n-scoot tactics

Cons:

• Armour is not as strong against up-gunned vehicles like the Pz.IV F2 and the T-34 (1942)
• The 38.1 mm side armour is vulnerable to even Rank I anti-tank fire and anti-aircraft guns
• Narrow tracks offer poor ground flotation, thus poor off-road capabilities
• Prone to damage by artillery barrages, tracks can be hit and the fuel supply can be ignited
• Ammunition storage is vulnerable to cooking off
• May tip over when travelling across steep inclines
• A shot through hull vision blocks can set off turret's ammo supply and hull sponson ammo and a lucky shot might even knock the M4A1 out
• Has a high profile especially when compared to other medium tanks
• The cast hull creates frontal weak spots with very little effective thickness, e.g. the triangles between upper front plate and the side, and the curved hull hatches

History

Development

The Battle of France in 1940 proved to America that their current tank arsenal would not be able to withstand a German assault. The only tanks in their inventory at that time was the M2 Light Tanks and the M2 Medium Tank, both are inadequate against the German Panzer IIIs and the Panzer IVs. The US Army, in response, ordered for a tank armed with a 75 mm gun. While a 75 mm gun was available for use, a turret able to mount the gun was not. So while the turret and tank design underwent development, the 75 mm would be mounted on the stopgap design, the M3 Lee tank in a sponson mount. This interim design put the 75 mm on a lower and limited traverse mount that restricted its firing angle, but it did give the Allies a tank with the gun, so it was issued by the thousands until a better design could be made.

During the M3's development, the designs of the 75 mm armed vehicle were being drawn up and submitted by the Ordnance Department. Specifications on the tank design were strict, with restrictions made on the tank's height, width, and weight in order to make it able to be transported over bridges, roads, railroads, and on ships. These specifications would help the army by making the tank be very flexible on strategic, logistical, and tactical grounds. On April 1941, the Armored Force Board chose the simplest of the designs, which was a redesigned M3 hull and chassis with a turret mounting the 75 mm gun designated the T6, completed in September 1941. This tank would then designated the Medium Tank M4 in American service. The tank would become the most used Allied tank during World War II as it was lent out by the thousands in the Lend-Lease program to the Allied countries. The British called the M4 the "Sherman", which coined into the tank's name M4 Sherman that it would be known as in history. The production for the Shermans began on October 1941 and would continue to be produced until the end of the war in 1945 with around 50,000 units produced, making it the second most-produced tank in World War II before the T-34 tank.

Design

Many variants of the Shermans were produced, but they all followed a similar layout. The driver and bow gunner sat in the front driving compartment, the fighting compartment in the middle housed the turret its three crew member, and in the back was the engine compartment. The Sherman used many features present in previous American tank designs, the vertical volute suspension system (VVSS) and radial engine from the M2 light tanks, and the sloping armour of the M2 Medium. This became a contributing factor on the Sherman's reliability on the field, as most of the design flaws were ironed out with the previous tank designs. The tank-mounted the 75 mm M3 gun, giving the tank very good AP and HE capabilities. The Sherman's turret traverse speed was very fast, able to traverse a full 360 degrees in only 15 seconds, which is considerably faster than the traverse speed on most German tanks. Another unique feature on the Sherman was the installation of a gyroscopic stabilizer on the gun and sight, making the Sherman one of the first produced tanks to incorporate those features. While the stabilization was only done for the vertical plane, it kept the gun stable enough to be able to shoot on the move effectively, with a study showing a 70 % hit probability on an enemy 300 to 1,200 yards away when moving at a speed of 15 mph. However, this feature was controversial among the crew and experiences with it vary.

The M4A1 Sherman model ran on a gasoline Continental R975C-1 radial engine and was one of the first models of the Sherman developed. The model in-game features the early M38 telescopic sight in the M4 periscope with no zoom, which was later replaced with an M55 telescopic sight in the gun mantlet by recommendation from the British. The tank's hull was fully cast, giving the tank a distinctive rounded slope front and sides. Though the rounded shape gave the frontal armour uneven angling, it provided adequate protection up to 100 mm in thickness in certain areas. Casting the hull took fewer man hours to perform, but suffered from the limited capability of most American factories and was hard to repair on the field. Thus, welding was prioritized as the primary manufacturing method in the other Sherman variants. Nevertheless, up to 6,281 M4A1s were produced from February 1942 to December 1943, out of the 49,234 Sherman units produced in the war.

Combat usage

European theater

The Shermans first saw combat in the North African Campaign in the Second Battle of El Alamein in October 1942 in the hands of the British. It was much quicker to reinforce the British armoured divisions with the more than 300 M4 Shermans sent to North Africa than it was to create new American ones. It proved much better than the German Panzer IIIs and Panzer IVs, able to eliminate them at distances more than 2,000 yards away. The Americans received their first Shermans in the next month in Operation Torch. However better the Shermans were to the German tanks at the time, the Allied armoured units still suffered casualties against the German tanks and anti-tank guns, most notably in the Battle of Kasserine Pass. In Italy, the Shermans proved much more mobile than the German Panzers, able to travel cross-country on the hilly terrain with ease. However, it was at this stage that the Sherman's shortcoming began to take face in the advent of the newer German tanks, the Tiger Is and Panthers. These two tanks featured armour that proved impenetrable when fired at the front, and with guns that could take out the Shermans from farther than the Sherman's effective combat range. The Shermans have to hit the side of these tanks for penetration and at ranges that were considered suicidal. Although programs were initiated to up-gun the Sherman with a 76 mm gun, American leaders determine that the Panther and Tigers would not be produced in large quantities and were not as great as a threat as these two vehicles could still be destroyed by the 75 mm gun and standard anti-tank equipment.

During the Invasion of France, it was clear that the Sherman's current build with a 75 mm gun was no longer going to cut it against the German armoured forces. While the Sherman was adequate against what little Panzer III and IVs the Germans have left and against infantry and fortifications with the 75 mm gun, the Panthers and Tigers were in much large quantity than expected, and proved better in armour and firepower to the Shermans. Though in the bocage country of France, the Allies lost more tanks to hidden anti-tank guns and infantry weapons than to tanks. Despite these losses, the mass production of M4 Sherman back in the United States ensured that enough tanks were available for the Allied Forces as they spearhead through France, plus the lack of any other capable tanks meant they had to use the Shermans for the time being. The large quantities of Shermans produced during the war gave the Allied armoured units a major advantage of being fully equipped as the German panzer divisions were rarely in full strength, with some US infantry divisions having more tracked vehicles than some of the panzer divisions. Due to the high attrition rates, tank crews sometimes add improvised armour onto their Shermans in the form of sandbags and logs in hopes of increased survival, but these were determined to be ineffective from evaluations. A more effective method was to have metal armour welded on in improvisation, and an official project was made for such "assault tanks" that ended with the M4A3E2 "Jumbos" with 250 made for the Battle of Normandy. During the Battle of Normandy, the first 76 mm Shermans on the M4A1 were put into combat in Operation Cobra in limited numbers. The Allies continued to primarily use the 75 mm Shermans until the Battle of the Bulge in Winter 1944, when the commanders request only 76 mm Shermans to be brought into Europe as the battle showed the intense armour disparity with the German's large numbers of Panthers and Tiger IIs. While new units arriving in Europe were armed exclusively with 76 mm armed-Shermans, the veteran units kept the 75 mm Shermans, to which it continued to do well against softer targets with little threat from German armour due to their extreme declining numbers.

Pacific theater

The M4 Sherman's importance in the Pacific theatre was less than that of the European theatre due to the different tactical doctrine established from the amphibious nature of combat. Only about 20 tank battalions fielded by the US Army were sent to support the Pacific theatre of operations, compared to the total 16 armoured divisions and 70 tank battalions they have in service. The low priority in tanks was due to the following reasons. Firstly, the jungle terrain on most of the islands fought for against the Japanese were unsuitable for the deployment of large-scale armoured units, relegating armour support to light tanks such as the M3 Stuarts. Secondly, the Japanese forces' armoured units were rather inferior to the American tank forces by 1943. While the Japanese Type 95 Ha-Go tank was comparable to the M2A4 light tank, the Shermans out gun these tanks by a large margin. Such a large margin that the tank crew prefer to use high-explosive shots against the Japanese tank than regular armour-piercing as the AP rounds would penetrate straight through without causing much damage in the interior of the tank. The Japanese developed the Type 3 Chi-Nu and the Type 4 Chi-To to fight back the Shermans, but these two never saw combat as they were kept at the Japanese Homeland for the defence against the Allied invasion.

The Shermans, when deployed, were superior to most of the Japanese anti-tank equipment and often were essential to some of the Marine's advances on some of the island assaults. In 1945, the equipping of flamethrower Shermans known as M4A3R3, nicknamed "Zippos", were a significant boost to the infantry's firepower in having a very long range of fire compared to the standard infantry-modelled flamethrowers with the benefit of being in an armoured vehicle. The Zippos are able to flush out enemy combatants from within heavily fortified bunkers and caves that would be dangerous for even flamethrower infantry to take out. The Japanese solution against the Shermans, other than with their 47 mm anti-tank guns, were often suicidal tactics ranging from placing satchel charges right onto the tank, using pole-mounted anti-tank mines to reach and destroy the tank or even simply throwing oneself underneath a tank with mine or other explosive and triggering it manually.

Lend-Lease

The Sherman tank was given out in large numbers to American Allies during World War II under the Lend-Lease policy. While America retained about 20,361 Shermans in the Army and Marine Corps, 17,184 went to Britain (about 34% of Shermans produced and 78% of Shermans given out) and the Soviet Union obtained 4,102 Shermans. China obtained 812 Shermans, Brazil with 53, and New Zealand and Australia for 153 Shermans total. Other countries using the Shermans were Poland, Free France, and Czechoslovakia. The British deployed the Sherman among their armoured squadrons in such a large number to become the standard tank of their armoured forces. The increased threat of German tanks in the European theatre also provoked the British to up-gun the M4 Sherman with a more capable gun, resulting in the Firefly.

Post-War

After the war, the Shermans continued serving America and its allies as the M4A3E8 with a new suspension and 76 mm gun. The M26 Pershing that was introduced late in World War II was phased out for the Shermans due to its unreliability, and the Sherman stayed until the M46 Patton was introduced. After being phased out of American service, many other countries still used the Sherman as their main tank, mainly Israel where they up-gun the tank with the much powerful post-war French 75 mm and 105 mm gun as the M-50 and M-51 respectively (nicknamed "Super Shermans"). These proved successful as they were able to fight against the Soviet-supplied T-54 tanks and T-34-85s in Middle East service, proving the Sherman as a successful and adaptable design for many years to come.

Archive of the in-game description

The M4A1 was an M4 medium tank with a cast hull, cast turret, and the 350 hp Continental R-975, a gas-powered radial engine. The M4A1 went into full-fledged production in February 1942, with 6,281 rolling off the lines between then and January 1944. The hull's front plate initially had viewing slits cut out, though later it was made from one piece. The front section of the gear compartment was made out of three pieces, subsequently becoming a single section. The M34 cannon mantlet was replaced with the M34A1 by 1943. M4A1 tanks were shipped to Great Britain as part of Lend-Lease. The Sherman's baptism by fire came in North Africa, where the British thought the new American tanks played a fairly significant role in the victory at El Alamein. M4A1s also served in Italy. The tank enjoyed a strong reputation in battle, quickly replacing the M3 as the Americans' main medium tank. The M4 turned out to be best for desert combat, a conclusion confirmed by post-war experience as well. The flat, wide open spaces in Africa were a perfect natural environment allowing it to exploit its reliability, high speed, comfortable interior, excellent field of view, and radio communications. The tank's range suffered, but the Allies handled that issue by streamlining their supply lines. In addition, tankers often carried along with extra fuel in canisters. A high silhouette made the M4 easy to target, and its armament was made obsolete in 1943 with the appearance of the German Pz.V and Pz.VI tanks. The M4's weaknesses were an engine, ammunition, and fuel tanks prone to fire and explosions due to its relatively light armour.
