The '''{{Specs|name}}''' is a rank {{Specs|rank}} American heavy tank {{Battle-rating}}. It was one of the first American tanks to be released with the American ground tree in [[Update 1.45 "Steel Generals"]]. It is built off a standard M4A3 chassis, with a T23 turret with a 75 mm gun, and up-armoured on nearly all sides. This gives the M4A3E2 boasts nearly 100 mm of frontal armour sloped at 47°, giving it a massive armour upgrade from the regular M4 Shermans. As a side note, the nickname "Jumbo" was likely never used during WWII, as there is no record of it. However, its use both on the Wiki and In-Game is still prevalent.

The M4A3E2 looks like a normal Sherman medium tank, but it is still a very heavy tank and is used as a breakthrough tank to attack fortified enemy positions. It is certainly not a medium tank like normal Shermans. It is a great tank when fighting Tigers as the 88mm cannons cannot penetrate the armour of the M4A3E2 from its sides when angled efficiently. As such it allows players to get close to Tigers and attack them from the sides, or force them to retreat. When fighting Panthers the M4A3E2 is less effective as the 75mm cannon on the Panther can penetrate the armour of the Jumbo Sherman from the front even when angled more than 30 degrees at 500 meters. Only at close range can high-velocity guns, such as Soviet 85mm or German 88mm guns, penetrate the frontal glacis. However, larger calibres, such as the Soviet 122mm gun, will slice right through the armour.

It takes on the general look of an [[M4A2|M4A2]] but is much more armoured (and also uses a Ford gasoline engine). The M4A3E2 features the double layered front armour giving the vehicle its distinctive 101.6 mm total front armour, giving its boast of being better armoured than the [[Tiger H1|Tiger I]]. The transmission housing is also considerably beefier too from the addition of armour at the area as well. The front of the T23-style turret is also distinctive with the very blocky gun mantlet and circular barrel shroud around the rather underwhelming 75 mm gun barrel.
 
  
−
The sides and suspension look like the usual game with the M4 Sherman series, but with minor differences. The flat side armour of the hull, instead of 38.1 mm thick, is now 76.2 mm thick for much stronger side protection. However, the lower side hull around the bogie suspension area is still only 38.1 mm thick, vulnerable to most regular anti-tank weapons. Another minor difference is the tracks, the T48 rubber chevron tracks are equipped with extended end connectors in an effort to improve ground pressure performance for the additional weight of the armour.
+
The '''M4A3E2 Sherman - Assault Tank''' is an armoured modification of the M4A3, which is the fourth variant of the early-generation [[M4 Sherman (Family)|Medium Tank M4 (Sherman) family]]. The U.S. Army decided in early 1944 that they needed an armoured version of a medium tank for an assault role in the forthcoming European Theatre of Operations (ETO). However, they had previously rejected proposals for such a vehicle, and time was running out. The decision was made to modify the newest standard U.S. Army medium tank of the time, the M4A3 Sherman, since the new [[T26E1-1|T26E1-1 heavy tank]] prototype would not be ready in time and earlier designs had been completely inadequate for the role. The vehicle evolved into the M4A3E2 Sherman - Assault tank, sometimes known as the Sherman Jumbo. With only 254 units constructed, it constituted less than 1% of overall M4 Sherman production. However, its unique design made a lasting impression, making it one of the most widely recognized M4 Sherman variants. It should be emphasized that the term 'Jumbo' does not exist in any military material and is probably certainly a post-war nickname, possibly developed by a model kit company. An extra 38 mm of armour plate was to be welded to the upper hull front and sides of the M4A3 variant, bringing the overall thickness to 101 mm on the front and 76 mm on the sides. The back upper hull and top, as well as the lower hull, remained unmodified. The turret was based on the T23 turret and had a similar interior arrangement as well as a complete basket, however, the pistol port was removed. The thickness was about 152 mm all around, however, it reduced to 63 mm at the back below the bulge. The 75 mm M3 tank gun was mounted in a modified M62 Gun mount designed for the 76 mm M1 tank gun. The M62's original 50 mm cast gun shield was reinforced with an additional 127 mm armour plate, resulting in a massive mantlet that covered over three-quarters of the turret front.
  
−
However, the rear does not have any extra armour and is much thinner. The roof of the tank is very thinly armoured as well, only having 19.5 mm on the hull and 25.4 mm on the turret, so beware as artillery barrages tend to set engine compartment modules on fire.
+
Introduced in [[Update 1.45 "Steel Generals"]], the M4A3E2 is a makeshift heavy tank based on the original M4A3 Sherman variant. Though it appears to be a standard M4A3 Sherman medium tank, it can absorb significantly more damage than any M4 Sherman variants and can efficiently assault enemy positions. The majority of common enemies in the M4A3E2 ranks struggle to penetrate this vehicle from the front. As you use the M4A3E2 to spearhead an aggressive drive, opponents will typically direct their fire towards you, letting your teammates attack enemy targets without less pressure. However, despite its impressive protection, the 75 mm M3 tank gun in the M4A3E2 is lacklustre. It lacks the armour penetration to engage most opponents within its ranks from the front. In order to properly destroy enemy vehicles, players will frequently have to flank the enemies for the weaker side armour. The M4A3E2 tracks have been enlarged with duckbill connectors to spread the tank's increased weight over a larger area, and a more powerful engine has been added to improve mobility.

While >160 mm of line-of-sight thickness is nothing to sneeze at, there are still a few guns around the M4A3E2's BR that can cleave through it with little effort. Give the German Long 88, Soviet 122mm, and 152mm guns the respect they deserve; they can easily knock the Jumbo out in one shot regardless of angle.
 +
 
 +
However, if you can't penetrate the M4A3E2's glacis, there are still points that were not (or could not be) well-armoured; namely, the machine gun port, cupola, and lower side.
 +
 
 +
The M4A3E2 presents very little frontal weak spots in an engagement. If possible, it is best to try and force the Jumbo to try and angle his vehicle. An angle of more than 30 degrees can expose the much weaker 38mm thick lower side armour. With a powerful enough gun, a round can penetrate this area and damage the crew, immobilize the tank, or detonate the ammo.
  
−
The M4A3E2 Jumbo presents very little frontal weak spots in an engagement. It is best to try and force the Jumbo to try and angle his vehicle towards the player or his allies. An angle more than 30 degrees can expose the much weaker lower side hull armour in the suspension that is only 38.1 mm thick. With a powerful enough gun, a round can penetrate this area and damage the crew, or even set off the ammunition all cluttered up on the bottom of the tank.
+
If the M4A3E2 decides not to angle significantly enough to expose its weak lower side, there are a few other areas to try and penetrate. The semi-spherical machine gun port is only about 60 mm thick, so nearly any gun around this BR can attempt to penetrate it. However, it is an extremely hard target to hit, especially when the Jumbo angles and moves back and forth. Make sure to aim for the gun port proper, as a shell that clips the horseshoe shaped bit of armour around it will generally fail to penetrate.
  
−
If a frontal engagement is unavoidable and is unfortunately armed with guns unable to penetrate through the front glacis, there are only two areas that are viable. First is the machine gun port, which is one of the areas that is not layered with the extra 38.1 mm added on top of the base armour. Guns like the Panzer IV 75 mm KwK 40 guns that are unable to cleave through the front glacis can push their luck in this area, with small "sweet spots" that the round can pass through. Another way to attack the M4A3E2 in this scenario is exploiting a shot-trap in the gun mantlet. The small corner flaps on the bottom corners of the gun mantlet have a tendency to deflect rounds downwards onto the 19.5 mm hull roof armour. While this will be left to the ricochet chances, it is still possible and can be used if no other scenarios are favourable.
+
The cupola of the M4A3E2 is another small weak point. Tanks like the Tiger 1 that lack the penetration to cut through the glacis can float a shell through the Jumbo's low cupola. An APHE shell that manages to detonate will generally kill the entire turret crew, crippling the tank.

In Tier I, Parts should, of course, be the prioritized module for field repairs. This will unlock Tier II modifications and grant access to the very vital FPE and M61 shot, the former for preservation against fires and the latter to improve combat effectiveness.

In Tier III, Crew Replenishment should be obtained for crew survival improvement and the APCR T45 shot for improved armour-piercing power. After that, everything else could be done at one's own priorities, but Engine should be invested for better automotive performances and M89 for the smoke shell. Fully upgraded, the Jumbo can glide around very fast for a heavy, so mobility upgrades are recommended.

The roof-mounted M2HB .50 cal heavy machine gun is very good at knocking out tracks, punching through lightly armoured vehicles and shooting down low-flying aircraft. Use it sparsely because of its low ammo count.

The small calibre of the M1919A4 machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help or to mow down minor obstacles blocking your line of sight.

The M4A3E2 is best in assaulting enemy positions with allies. Its great mobility for a heavy tank, especially with its armour, makes it a vehicle able to charge into battle and take anything head-on with confidence. It can act as a bullet magnet against enemy tanks more worried about the M4A3E2, diverting fire that would've gone to more vulnerable teammates. Though the 75mm gun's AP performance is not suited to the type of enemies expected at the BR, it can still harass enemies and the gun is lethal enough that enemies will be forced to show their front armour towards the Jumbo else a 75 mm penetrates their side armour. Their focus on the Jumbo can allow allies to move around and eliminate them. During all this, take care not to over-angle and show the lower side armour too much as this will allow vehicles to penetrate through down there and damage modules, even the ammunition storage if they are lucky.

Another role the M4A3E2 is good it is as a flanker. Due to its great mobility as a heavy tank, the M4A3E2 Jumbo can manoeuvre like a medium tank around the battlefield. This is also beneficial to the 75 mm gun as it would permit the M4A3E2 a chance to attack the weaker side armours of enemy vehicles. Once flanking around and finding a prime position in a firing angle right into an enemy chokepoint, minimize exposure to anything but the front armour and the M4A3E2 can remain a formidable obstacle to all opponents. Take care not to be outflanked by enemy players aware of the M4A3E2 position.

Due to the M4A3E2 Jumbo having a slightly higher battle-rating than the other M4 Shermans at 4.7, it can be up-tiered against tanks such as the [[Panther D]] and [[Tiger_H1|Tiger H1]], meaning it's 75 mm cannon starts becoming less effective. For this reason, it is advisable to take the T45 APCR ammo into battle once unlocked, at least enough to take on the armoured targets the Jumbo will face.

The Soviet 85 mm can be a threat, so caution is advised when going up against tanks armed with the 85 mm, such as the [[T-34-85]], [[SU-85]], and [[IS-1]]. The [[Jagdpanzer 38(t)]] and [[Jagdpanzer IV]] can be tricky when facing off against them. Their frontal armour is too thick and sloped for the 75 mm M3 gun to have any effect on it. For these two targets, it is advised to target their tracks and transmission and then flank for a side shot, where the armour is much weaker. Also, the [[Dicker Max]] wields a 105 mm that can penetrate the front plate of the M4A3E2 Jumbo, so caution is advised against those as well. Finally, there is one common opponent from the Soviet/Chinese tree: IS-2. Its 122 mm gun can easily penetrate the Jumbo, regardless of angle and distance. To destroy it, shoot at it when it's reloading or is unaware of your presence. For the 1943 model, aim at the cupola or the curved part of its hull armour that blends into the side. It has only 4 crew so killing all the turret crew (3, which is easy) will destroy it. For the 1944 model, only aim at the turret or the cupola as its hull is very strong.

Also, the [[Dicker Max]] wields a 105 mm that can penetrate the front plate of the M4A3E2 Jumbo, so caution is advised against those as well. The 2 last common threats from the German tree are the [[Panzer IV/70(A)]] and [[Panzer IV/70(V)]]. The same advice can be taken from the Jagdpanzer 38(t) and Jagdpanzer IV but also considering that these tank destroyers can penetrate your frontal hull and turret under 500 m. The [[SU-152]] and [[ISU-152]] with the stock APHE round can sometimes penetrate your frontal plate, however, special caution should be paid to the ISU-152. From the front, the 75 mm gun will struggle to penetrate the armour of the ISU-152 but an ISU-152 using the HEAT shell can easily penetrate anywhere in the front hull and turret. The best tactic to countering the ISU-152 is to attempt to flank it as the side armour is only 75 mm thick. If flanking it is not possible, aim for the barrel, as it will reduce the accuracy of the ISU-152's main gun, and many ISU-152 players will not shoot the main gun if the barrel is damaged. Remember to wait for the ISU-152 to shoot before engaging it, as the reload time of the ISU-152 is very long. Finally, there is one more common opponent from the Soviet/Chinese tree: [[IS-2 (Family)|IS-2]]. Its 122 mm gun can easily penetrate the Jumbo, regardless of angle and distance. To destroy it, shoot at it when it's reloading or is unaware of your presence. For the 1943 model, aim at the cupola or the curved part of its hull armour that blends into the side. It has only 4 crew so killing all the turret crew (3, which is easy) will destroy it. For the [[IS-2 (1944)|1944 model]], only aim at the turret or the cupola as its hull is very strong.

Shooting the commander's cupola is often necessary to destroy or at least disable heavily armored tanks. The Tiger H1 cannot be frontally penetrated with the APHE or AP shell, or by the APCR when angled, so the best place to shoot it is the commander's cupola, with the APHE shell. The same can be used against T-34-85, IS-1 and IS-2 tanks.

In Tier I, ''Parts'' should, of course, be the prioritized module for field repairs. This will unlock Tier II modifications and grant access to the very vital ''FPE'' and ''M61 shot'', the former for preservation against fires and the latter to improve damage in the battlefield.
+
Against the Jumbo, if you encounter one, shoot for the barrel and the tracks, then attempt to either flank it and shoot from the sides, or fire at the enemy's the machinegun port. This is not completely reliable due to the weak gun, sometimes only the machinegunner will be killed, but it is the only chance to frontally destroy it.
  
−
Then in Tier III, ''Crew Replenishment'' should be obtained for crew survival improvement and the APCR ''T45 shot'' for improved armour-piercing power. After that, everything else could be done at one's own priorities, but ''Engine'' should be invested for better automotive performances and ''M89'' for the smoke capabilities.

Even before the invasion of Normandy, the Allied commanders had to figure out a method in order to breach heavily-defended fortification lines such as the Siegfried Line blocking the path from France to Germany. One of the solutions was for the implementation of "assault tanks" to enter enemy territory and root out the enemy fortifications. The initial plan was for the production of the [[M26|M26 Pershing]] tanks to fulfil this role, but setbacks in its development caused the M26 deployment to be delayed until 1945. A quick solution must be made to fill this "assault tank" role for the invasion of Europe in 1944.

The US ordinance then took their abundant [[M4|M4 Shermans]] in stock and fixed them up for the new role they've been assigned in. Although keeping the same engine, the armour was upped from around 76.2 mm initial thickness to 102 mm and angled at 47 degrees from vertical. This angle would influence later Sherman design such as the M4A3 by changing the original 56 degrees angled glacis with protruding crew hatches to 47 degrees angled glacis without any protrusion from the crew hatches. This modified M4 Sherman's armour when angled would then be 150 mm line-of-sight (LOS) thick and 180 mm effective. The side armour is also increased to 76.2 mm thick and the turret is redesigned to provide more protection. These modified Shermans were designated the '''M4A3E2''' by the Ordnance Department, whereas the nickname "Jumbo" was likely a post-war invention. At the end of the modifications, the Sherman "Jumbo" now weighed about 42 tons and moves a lower speed of 22 miles per hour. A drawback to the increased weight of the Sherman is that the Vertical Volute Suspension System (VVSS) from the Sherman was unable to take the weight easily, so extra care was taken by the crew members to not break the suspension.

In March of 1944, the US Army ordered for 254 of these vehicles to be delivered for use for European Operations. Intended for the assault on the Normandy Beachhead, it was deployed in Normandy after D-Day to assist the infantry push through German defences. The M4A3E2 originally came with the 75 mm guns to support infantry with its better HE shells compared to the planned 76 mm instalment, but the 76 mm was installed later in the campaign and called the [[M4A3E2 (76) W|M4A3E2 (76) W Jumbo]].

When the war in the European Theater ended, the M4A3E2s were then placed stateside for the preparation for the invasion of the Japanese Home Islands. However, this was never to be fulfilled as Japan then surrendered to the United States in September 1945. The M4A3E2 Shermans proved to be a very effective stop-gap solution until heavier armoured tanks such as the Pershing could come into play. In 1948, about 96 Sherman Jumbos still remained in US inventory.

"The M4 Sherman went through its most interesting modification at the end of 1943, when American builders presented a compromise design. It was a direct infantry support tank to be used at the beginning of 1944 during infantry landings in Northern Europe. The solution, which was quite simple, came about after it became clear that the T26E1 heavy assault tank would be ready for full-scale production no earlier than January 1945: boost the tank's armor to 10 cm. At the same time a heavier turret was designed with 10.5 cm armor, the changes together resulting in a tank that weighed in at 38 tons. Experience on the front showed that modernized tracks with fixed grousers were the best option, and they ended up giving the new tank a significant speed boost. It was able to traverse rough terrain at a top speed of 22 mph.

Description

The M4A3E2 Sherman - Assault Tank is an armoured modification of the M4A3, which is the fourth variant of the early-generation Medium Tank M4 (Sherman) family. The U.S. Army decided in early 1944 that they needed an armoured version of a medium tank for an assault role in the forthcoming European Theatre of Operations (ETO). However, they had previously rejected proposals for such a vehicle, and time was running out. The decision was made to modify the newest standard U.S. Army medium tank of the time, the M4A3 Sherman, since the new T26E1-1 heavy tank prototype would not be ready in time and earlier designs had been completely inadequate for the role. The vehicle evolved into the M4A3E2 Sherman - Assault tank, sometimes known as the Sherman Jumbo. With only 254 units constructed, it constituted less than 1% of overall M4 Sherman production. However, its unique design made a lasting impression, making it one of the most widely recognized M4 Sherman variants. It should be emphasized that the term 'Jumbo' does not exist in any military material and is probably certainly a post-war nickname, possibly developed by a model kit company. An extra 38 mm of armour plate was to be welded to the upper hull front and sides of the M4A3 variant, bringing the overall thickness to 101 mm on the front and 76 mm on the sides. The back upper hull and top, as well as the lower hull, remained unmodified. The turret was based on the T23 turret and had a similar interior arrangement as well as a complete basket, however, the pistol port was removed. The thickness was about 152 mm all around, however, it reduced to 63 mm at the back below the bulge. The 75 mm M3 tank gun was mounted in a modified M62 Gun mount designed for the 76 mm M1 tank gun. The M62's original 50 mm cast gun shield was reinforced with an additional 127 mm armour plate, resulting in a massive mantlet that covered over three-quarters of the turret front.

Introduced in Update 1.45 "Steel Generals", the M4A3E2 is a makeshift heavy tank based on the original M4A3 Sherman variant. Though it appears to be a standard M4A3 Sherman medium tank, it can absorb significantly more damage than any M4 Sherman variants and can efficiently assault enemy positions. The majority of common enemies in the M4A3E2 ranks struggle to penetrate this vehicle from the front. As you use the M4A3E2 to spearhead an aggressive drive, opponents will typically direct their fire towards you, letting your teammates attack enemy targets without less pressure. However, despite its impressive protection, the 75 mm M3 tank gun in the M4A3E2 is lacklustre. It lacks the armour penetration to engage most opponents within its ranks from the front. In order to properly destroy enemy vehicles, players will frequently have to flank the enemies for the weaker side armour. The M4A3E2 tracks have been enlarged with duckbill connectors to spread the tank's increased weight over a larger area, and a more powerful engine has been added to improve mobility.

Notes:

  • Suspension wheels are 15 mm thick, while bogies are 10 mm thick and tracks are 20 mm thick.
  • Belly armour is 25.4 mm thick.
  • Hull underside right above the tracks is 9.5 mm thick.

While >160 mm of line-of-sight thickness is nothing to sneeze at, there are still a few guns around the M4A3E2's BR that can cleave through it with little effort. Give the German Long 88, Soviet 122mm, and 152mm guns the respect they deserve; they can easily knock the Jumbo out in one shot regardless of angle.

However, if you can't penetrate the M4A3E2's glacis, there are still points that were not (or could not be) well-armoured; namely, the machine gun port, cupola, and lower side.

The M4A3E2 presents very little frontal weak spots in an engagement. If possible, it is best to try and force the Jumbo to try and angle his vehicle. An angle of more than 30 degrees can expose the much weaker 38mm thick lower side armour. With a powerful enough gun, a round can penetrate this area and damage the crew, immobilize the tank, or detonate the ammo.

If the M4A3E2 decides not to angle significantly enough to expose its weak lower side, there are a few other areas to try and penetrate. The semi-spherical machine gun port is only about 60 mm thick, so nearly any gun around this BR can attempt to penetrate it. However, it is an extremely hard target to hit, especially when the Jumbo angles and moves back and forth. Make sure to aim for the gun port proper, as a shell that clips the horseshoe shaped bit of armour around it will generally fail to penetrate.

The cupola of the M4A3E2 is another small weak point. Tanks like the Tiger 1 that lack the penetration to cut through the glacis can float a shell through the Jumbo's low cupola. An APHE shell that manages to detonate will generally kill the entire turret crew, crippling the tank.

In Tier I, Parts should, of course, be the prioritized module for field repairs. This will unlock Tier II modifications and grant access to the very vital FPE and M61 shot, the former for preservation against fires and the latter to improve combat effectiveness.

In Tier III, Crew Replenishment should be obtained for crew survival improvement and the APCR T45 shot for improved armour-piercing power. After that, everything else could be done at one's own priorities, but Engine should be invested for better automotive performances and M89 for the smoke shell. Fully upgraded, the Jumbo can glide around very fast for a heavy, so mobility upgrades are recommended.

Ammunition

  • M72 shot - AP - Solid shot, stock shell. An armour-piercing shell with acceptable penetration but poor post-penetration damage.
  • M48 shell - HE - A low-velocity shell useful against soft targets, in particular when hitting an open-topped vehicle. Harmless against any enclosed vehicle with more than 10 mm of armour.
  • M61 shot - APCBC - A capped armour-piercing shell with a better penetration than the M72 thanks to its ballistic cap and a good post-penetration damage thanks to its explosive filler.
  • T45 shot - APCR - Subcalibre round with high penetration but only on flat surfaces, with a high muzzle velocity but a poor post-penetration damage potential.
  • M89 - Smoke shell - A very low-velocity shell deploying a smoke screen on impact, useful to blind enemy vehicles that are too remote for you to disable so that you can progress towards objectives.

The small calibre of the M1919A4 machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help or to mow down minor obstacles blocking your line of sight.

Usage in battles

The M4A3E2 is best in assaulting enemy positions with allies. Its great mobility for a heavy tank, especially with its armour, makes it a vehicle able to charge into battle and take anything head-on with confidence. It can act as a bullet magnet against enemy tanks more worried about the M4A3E2, diverting fire that would've gone to more vulnerable teammates. Though the 75 mm gun's AP performance is not suited to the type of enemies expected at the BR, it can still harass enemies and the gun is lethal enough that enemies will be forced to show their front armour towards the Jumbo else a 75 mm penetrates their side armour. Their focus on the Jumbo can allow allies to move around and eliminate them. During all this, take care not to over-angle and show the lower side armour too much as this will allow vehicles to penetrate through down there and damage modules, even the ammunition storage if they are lucky.

Another role the M4A3E2 is good it is as a flanker. Due to its great mobility as a heavy tank, the M4A3E2 Jumbo can manoeuvre like a medium tank around the battlefield. This is also beneficial to the 75 mm gun as it would permit the M4A3E2 a chance to attack the weaker side armour of enemy vehicles. Once flanking around and finding a prime position in a firing angle right into an enemy chokepoint, minimize exposure to anything but the front armour and the M4A3E2 can remain a formidable obstacle to all opponents. Take care not to be outflanked by enemy players aware of the M4A3E2 position.

Due to the M4A3E2 Jumbo having a slightly higher battle-rating than the other M4 Shermans, it can face tanks such as the Panther D and Tiger H1, meaning its 75 mm cannon starts becoming less effective. For this reason, it is advisable to take the T45 APCR ammo into battle once unlocked, at least enough to take on the armoured targets the Jumbo will face.

The Soviet 85 mm can be a threat, so caution is advised when going up against tanks armed with the 85 mm, such as the T-34-85, SU-85, and IS-1. The Jagdpanzer 38(t) and Jagdpanzer IV can be tricky when facing off against them. Their frontal armour is too thick and sloped for the 75 mm M3 gun to have any effect on it. For these two targets, it is advised to target their tracks and transmission and then flank for a side shot, where the armour is much weaker. Also, the Dicker Max wields a 105 mm that can penetrate the front plate of the M4A3E2 Jumbo, so caution is advised against those as well. The 2 last common threats from the German tree are the Panzer IV/70(A) and Panzer IV/70(V). The same advice can be taken from the Jagdpanzer 38(t) and Jagdpanzer IV but also considering that these tank destroyers can penetrate your frontal hull and turret under 500 m. The SU-152 and ISU-152 with the stock APHE round can sometimes penetrate your frontal plate, however, special caution should be paid to the ISU-152. From the front, the 75 mm gun will struggle to penetrate the armour of the ISU-152 but an ISU-152 using the HEAT shell can easily penetrate anywhere in the front hull and turret. The best tactic to countering the ISU-152 is to attempt to flank it as the side armour is only 75 mm thick. If flanking it is not possible, aim for the barrel, as it will reduce the accuracy of the ISU-152's main gun, and many ISU-152 players will not shoot the main gun if the barrel is damaged. Remember to wait for the ISU-152 to shoot before engaging it, as the reload time of the ISU-152 is very long. Finally, there is one more common opponent from the Soviet/Chinese tree: IS-2. Its 122 mm gun can easily penetrate the Jumbo, regardless of angle and distance. To destroy it, shoot at it when it's reloading or is unaware of your presence. For the 1943 model, aim at the cupola or the curved part of its hull armour that blends into the side. It has only 4 crew so killing all the turret crew (3, which is easy) will destroy it. For the 1944 model, only aim at the turret or the cupola as its hull is very strong.

Shooting the commander's cupola is often necessary to destroy or at least disable heavily armored tanks. The Tiger H1 cannot be frontally penetrated with the APHE or AP shell, or by the APCR when angled, so the best place to shoot it is the commander's cupola, with the APHE shell. The same can be used against T-34-85, IS-1 and IS-2 tanks.

Against the Jumbo, if you encounter one, shoot for the barrel and the tracks, then attempt to either flank it and shoot from the sides, or fire at the enemy's the machinegun port. This is not completely reliable due to the weak gun, sometimes only the machinegunner will be killed, but it is the only chance to frontally destroy it.

Pros and cons

Pros:

  • Decent 75 mm gun with APCR rounds
  • High rate of fire for the main gun
  • Excellent gun depression
  • Very strong turret armour from all sides, very good at hull down position
  • Very good at leading a spearhead towards a capture point where it can provide cover to weaker allied tanks with more powerful guns
  • Excellent frontal armour and excellent all around turret armour
  • Can absorb a lot of damage
  • Good mobility
  • Equipped with gun stabilizer working up to 24 km/h, making it capable of shooting while moving
  • Good acceleration
  • Incredibly tough when angled
  • Wide tracks enable it to have decent off-road mobility
  • Learning curve from previous Sherman variant will help a lot at mastering this tank

Cons:

  • 75 mm M3 gun lacks penetration against heavy tanks
  • It needs allies support to be effective in battle as it cannot deal serious damage on its own
  • Armour weak spot above the gun mantlet
  • Small bottom corners on M4A3E2 gun mantlet can serve as shot traps
  • Side armour better than normal, but still weak, but the lower side hull armour is even worse
  • Very thin rear armour
  • Inability to compound angle greatly due to very weak lower side hull armour that would be penetrated
  • Tall profile makes it a bigger target
  • Bad off-road manoeuvrability
  • Low top speed
  • Bad reverse speed
  • Hull MG is a weak spot
  • Due to the layered armour at the front and the armour over-matching mechanic, the upper glacis armour can be dubious in that it does not reliably ricochet shells, particularly those from large calibre guns like the T-34-85
  • Stock round struggles a noticeable amount at this BR, struggling to penetrate common enemies
  • The frontal armour advantage is negated in an uptier against more powerful guns and chemical projectiles

History

Development

Even before the invasion of Normandy, the Allied commanders had to figure out a method in order to breach heavily-defended fortification lines such as the Siegfried Line blocking the path from France to Germany. One of the solutions was for the implementation of "assault tanks" to enter enemy territory and root out the enemy fortifications. The initial plan was for the production of the M26 Pershing tanks to fulfil this role, but setbacks in its development caused the M26 deployment to be delayed until 1945. A quick solution must be made to fill this "assault tank" role for the invasion of Europe in 1944.

US Ordnance then took their abundant M4 Shermans in stock and fixed them up for the new role they've been assigned in. Although keeping the same engine, the armour was upped from around 76.2 mm initial thickness to 102 mm and angled at 47 degrees from vertical. This angle would influence later Sherman design such as the M4A3 by changing the original 56 degrees angled glacis with protruding crew hatches to 47 degrees angled glacis without any protrusion from the crew hatches. This modified M4 Sherman's armour when angled would then be 150 mm line-of-sight (LOS) thick and 180 mm effective. The side armour is also increased to 76.2 mm thick and the turret is redesigned to provide more protection. These modified Shermans were designated the M4A3E2 by the Ordnance Department, whereas the nickname "Jumbo" was likely a post-war invention. At the end of the modifications, the Sherman "Jumbo" now weighed about 42 tons and moves a lower speed of 22 miles per hour. A drawback to the increased weight of the Sherman is that the Vertical Volute Suspension System (VVSS) from the Sherman was unable to take the weight easily, so extra care was taken by the crew members to not break the suspension.

In March of 1944, the US Army ordered for 254 of these vehicles to be delivered for use for European Operations. Intended for the assault on the Normandy Beachhead, it was deployed in Normandy after D-Day to assist the infantry push through German defences. The M4A3E2 originally came with the 75 mm guns to support infantry with its better HE shells compared to the planned 76 mm instalment, but the 76 mm was installed later in the campaign and called the M4A3E2 (76) W Jumbo.

Combat usage

The M4A3E2 was well-liked by the crew and commanders due to its protection value. Despite the weight difference and strain on the suspension, it performed reliably and could absorb damage that would otherwise destroy regular Shermans. Later in the war, when the quantity of the M4 Sherman "Jumbos" were unable to meet the demand, George S. Patton ordered for existing M4 Shermans to weld on armour plates scavenged from knocked out tanks to makeshift "on-the-field" Jumbos. This caused the newer Shermans such as the M4A3 (76) W HVSS could have the same protection by welding metal onto the hull. One of the Jumbo's notable participation in the war was in Patton's Third Army where it spearheaded the assault to Bastogne to relieve the pinned down 101st Paratroopers (though they deny needing a "rescue").

When the war in the European Theater ended, the M4A3E2s were then placed stateside for the preparation for the invasion of the Japanese Home Islands. However, this was never to be fulfilled as Japan then surrendered to the United States in September 1945. The M4A3E2 Shermans proved to be a very effective stop-gap solution until heavier armoured tanks such as the Pershing could come into play. In 1948, about 96 Sherman Jumbos still remained in US inventory.


Archive of the in-game description

The M4 Sherman went through its most interesting modification at the end of 1943, when American builders presented a compromise design. It was a direct infantry support tank to be used at the beginning of 1944 during infantry landings in Northern Europe. The solution, which was quite simple, came about after it became clear that the T26E1 heavy assault tank would be ready for full-scale production no earlier than January 1945: boost the tank's armour to 10 cm. At the same time a heavier turret was designed with 10.5 cm armour, the changes together resulting in a tank that weighed in at 38 tons. Experience on the front showed that modernized tracks with fixed grousers were the best option, and they ended up giving the new tank a significant speed boost. It was able to traverse rough terrain at a top speed of 22 mph.

The Fisher Tank Arsenal launched production of the M4A3E2 in May 1944 and finished in June of the same year. The tanks, which were bequeathed the nickname "Jumbo", were delivered to Europe that fall and served successfully through the end of the war.
