The Assault Tank M4A3E2 (76) W Jumbo is a rank IV American heavy Tank with a battle rating of 6.0 (AB/RB/SB). It was introduced in Update 1.45 "Steel Generals" in the initial batch of US vehicles available at launch. Taking from its predecessor, the M4A3E2, it is improved with a more powerful 76 mm cannon that allows it to take on the majority of Rank III and some of the Rank IV Tanks. 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.

突击坦克M4A3E2 (76) W Jumbo是美国IV级重型坦克，权重为6.0 (街机/历史/全真)。它是在1.45版本“钢铁将军”中引入的，也就是在首批登场的美国陆军科技树中。在其前身M4A3E2的基础上，它得到了更强大的76毫米坦克炮，这使得它可以对付大多数的III级坦克和一些IV级坦克。顺便一提，昵称“巨无霸”可能在二战期间从未被使用过，因为没有关于它的记录。然而，“巨无霸”一称在Wiki和游戏中的使用仍然非常普遍。

The M4A3E2 (76) W Jumbo is an all-around good Tank with no major limitations or advantages, with average speed, manoeuvrability and thick frontal armour, making it a 'jack of all trades Tank' equally good in defensive tactics as well as offensive tactics. staying behind good cover, exposing only the thick gun mantlet and engaging targets in long range, or offensive tactics. It's 2 main advantage is that it has a fast firing 76 mm gun, combined with high penetration rounds,and it can be used to quickly disable and overwhelm otherwise heavier targets. Its armour is also excellent - the hull armour is just 1 mm short of the Tiger I's hull, and that is not even taking into account the sloping, making the hull next to impossible to penetrate frontally, and your sides are also up armoured, so unlike the Shermans, your angling will not cause you to be shot through the side. Angling with this Tank will make you nearly indestructible to enemy fire. Compare this to the very tough Tiger I at the same battle rating. Beware, your hull is not up armoured from the rear, and most rounds at it's BR will set the engine on fire, and some will even go into the fighting compartment. You should also beware that you are not always indestructible, and things like the Tiger II (P) will penetrate you, even when angled. Another final thing to keep in mind is that despite you mainly fighting other 5.7 vehicles like Panthers, the battle rating will sometimes get you up against tougher opponents like the T-44 and the dreaded Tiger II (H), and if in arcade, even the terrifying T29.

76“酱爆”是一个六边形战士，没有很突出的缺点或优点，具有较为均衡的速度、机动性和厚实的正面装甲，这使其成为“全能坦克”，它在防守战术和进攻战术上都很好。可以呆在掩体后面卖头来与敌人远距离交火，也可以采取进攻战术。它有两个主要优势：一是它有一门可以快速射击的76毫米炮，且有高穿弹的加持，使得它可以快速地摧毁和击溃其他重装甲目标。二是它的装甲也是很靠谱的，它的车体装甲厚度只比虎式坦克少1毫米，“酱爆”甚至不用考虑摆角度，就可以使车体正面变得几乎坚不可摧，“酱爆”的车体侧装甲也不错，所以不同于“谢尔曼”，“酱爆”稍微漏点儿侧面钓鱼不会像馒头那样当场暴毙。“酱爆”稍微摆点儿角度便可以让你在敌人的火力下变得几乎坚不可摧。这与同样非常强悍的虎式坦克在6.0的表现打法差不多。注意，你的菊花比较脆，大多数同权重的炮弹都能点燃你的发动机，有些甚至会一路进♂入战斗室。你还应该注意，你并非总是坚不可摧的，像虎王(P)这样的坦克会击穿你的，即便你摆了角度。另一件需要记住的事情是，尽管你主要是和其他5.7车(比如豹式坦克)作战，但由于权重的原因有时你会面对更强硬的对手，比如T-44和可怕的虎王(H)，如果是在街机模式中，你甚至会遇到可怕的T29。

To start out, you will want to get Tracks, Parts, then M79 Shot, and work your way from there, as those are the core components of the M4A3E2 (76) W Sherman Jumbo. With the better ammunition, you will be able to penetrate more and be far more dangerous on the field. And with Tracks & Parts, you won't need to worry about the lights/mediums that keep popping out your tracks to get to your side or backside. After getting these three things, it's best to work on manoeuvrability and M93 Shot as a first priority.

开始时，你应该首先研发履带，维修套件，然后是M79炮弹（?？?灭火呢?），并从那里工作的方式，因为这些是76“酱爆”的核心组件。有了更好的炮弹，你将能够在战场上击穿更多、更危险的敌人。有了履带和维修套件，你就不需要担心轻型/中型不断地射击你的履带，然后绕到你的侧面或背面了。在得到这三样东西之后，接下来最好是抓紧改善机动性和研发M93炮弹。

弹药

M62 Shot - M62 shot is the standard stock shell of the M4A3E2 (76) W. With a 149 mm top penetration, it usually won't be able to destroy heavy opponents or Tank destroyers it will see at its BR from the front, however, the armour makes up for it to have more time looking for a good shot. Although this is the stock shell it is quite handy, and can deal with many of the opponents at its BR, if you know where to aim. For one thing, this shell can destroy most cannon barrels with a direct hit, but this should not be your go-to in most situations.

 M62炮弹-M62炮弹是76“酱爆”的白板默认弹。它拥有149毫米的穿深，它通常从正面淦不动同权重的重型对手或坦克歼击车，然而，装甲使其拥有更多时间来寻找一个好的射击窗口。虽然它是白板弹，但它还是挺好用的，如果你知道该朝哪儿打的话，它可以解决同权重的许多对手。还有，也可以直接用它来拆炮，但这并不是你在大多数情况下的首选。

M42A1 Shot - This is the HE shell of the M4A3E2 (76) W. With 7 mm penetration at all ranges, it's best to use this when fighting AA trucks or other lower-armoured Tanks. It's advised to only carry 0-5 of these shells as you won't really need them, but they're useful for when a pesky AA truck comes around the corner and shoots your cannon barrel off when your firing APCR at it. 

M42A1炮弹-这是M4A3E2 (76)W的HE，在任何距离上都有7毫米的穿深，最好在淦防空卡车或其他脆皮坦克时使用。建议只带0-5发HE，因为你不会真的需要它们，但它们是有用的，当一个讨厌的AA卡车来到拐角处，并射击你的炮管，而你却在打APCR时。

M79 Shot - The M79 shot is a clear upgrade from the M62 shot, with more than 30mm more penetration, this will pack a punch. However, you will need to make sure you know your enemy Tank's guts, as this does not fragment nor have a HE filler, and will rely on your aiming skills to destroy the core components of a Tank. Just like the M93 shot, this Tank shell will not explode in the Tank, but rather go straight through. It's best to carry these shells instead of the M62, but when you get the upgrade to M93 don't carry any at all. 

M79炮弹- M79炮弹明显是M62炮弹的升级版，穿深比M62炮弹多30毫米。然而，你需要确保你知道敌人坦克的要害，因为它没有破片，也没有炸药填充，并将依靠你的瞄准技能来摧毁敌人坦克的核心部件。就像M93炮弹一样，这款炮弹不会在坦克里爆炸，而是直接穿过坦克。最好是携带这种炮弹而不是M62，但是当你解锁升级到M93炮弹时，就不要带它了。

M93 Shot - This is the last shot upgrade of the M4A3E2 (76) W. With a penetration upgrade of more than 110 mm from the M62 shot and more than 70 mm than the M79 shot, this will be the best shell for the M4A3E2 (76) W Sherman Jumbo. With this shell, you'll be able to pen even the most armoured of opponents, except perhaps the occasional Tiger II or IS-2 mod. However, it's best to carry at least 35-50 shells of this, as this should be your main shell during combat. 

M93炮弹-这是M4A3E2 (76) W的最终炮弹的型号，穿深比M62炮弹提高了110多毫米，比M79炮弹提高了70多毫米，这将是M4A3E2 (76) W谢尔曼巨无霸火炮配备的最好炮弹。有了这种炮弹，你甚至可以击穿装甲最强的敌人，除了偶尔会遇到的虎王坦克或者IS-2 1944型。不过，最好携带至少35-50发这样的炮弹，因为这应该是你在战斗中的主力弹种。

译者注：现版本M79过于废拉，不建议携带。M93后效差，击杀效率低，仅建议带几发以备不时之需。

The M4A3E2's regular enemies are Tiger I and Panthers of all variants and Jagdpanzer IV/70s which can be dealt with using the tactics described above. Occasionally you will face Tiger IIs and Jagdpanthers, the best way to deal with them is to flank and disable them quickly. However, if this is not possible, you should not engage them, and await help. Beware though, that things like the Tiger II (H) and T29 and Caernarvon might get away with destroying all those trying to help you, ending up with your untimely end. Avoid engaging them frontally at all costs, especially at long ranges.

M4A3E2的一般对手是各种型号的虎式坦克和豹式坦克以及长四歼，可以使用上面描述的战术来对付它们。偶尔你会遇到虎王坦克和猎豹，对付他们最好的方法是去绕侧并迅速摧毁他们。然而，如果不能绕，那你应该回避它们，并等待队友支援。不过要注意的是，像虎王(H)、T29和卡那封这样的敌人可能会摧毁所有试图支援你的人，最终导致你过早的阵亡。无论如何都要避免与它们正面交战，尤其是在相隔较远距离时。

Although this is based on a medium Tank, the Tank is not as fast as the other mediums at its rank. Because of the heavier armour, this Tank will be a few more miles slower than the rest of the Tanks. However, this does not mean that the Tank is bad. Most Russian Tanks at this rank will usually have a very easy to spot the point where the hull and turret meet together, that point is usually under-armoured and a well-placed shot will usually cripple the Tank and the turrets horizontal will be gone.

虽然“酱爆”是基于一辆中坦改装的，但它的速度并不如其他同等级的中坦快。由于装甲较重，这款坦克的速度将比其他坦克慢几英里。然而，这并不意味着“酱爆”不彳亍。大多数这个等级的苏联坦克通常都能很容易地找到车体和炮塔的连接处，这个位置通常装甲防护不足，正确的射击通常会使坦克瘫痪，同时损坏方向机。

Never show your side. No matter what you do, never show your side. Your front is the most armoured piece on your Tank, and you must use that your advantage. Never allow the enemy to flank or ambush you. To ensure that you can get a good shot, find out what enemy Tanks you'll see in the Jumbo then check where their ammo is and how much armour is protecting that area. If you know you can penetrate that, go for the ammo/gunner/gun, as the M93 shot does not fragment or have a HE filler, it simply pierces the Tank and goes straight through.

不要暴露你的侧面。不管你做什么，都不要暴露自己的侧面。你的正面是你坦克装甲最强的部分，你必须利用这一点。永远不要让敌人通过绕侧袭击你或蹲坑伏击到你。为了确保你可以抓住一个良好的射击机会，弄明白“酱爆”面对的是什么敌人，然后找找它们的弹药架在哪、有多少装甲保护该地区。如果你知道你可以击穿它，去淦弹药架/炮手/主炮，因为M93的炮弹没有破片，也没有炸药填充，它仅仅是简单地直接穿过坦克。

In urban environments, you're going to want to move up with the rest of the group, however, don't move up as the lead Tank because you will surely find a nasty surprise at the end of the road. When facing Tiger II's, they will be able to pen anywhere they want in your frontal armour, even your thickest point (turret) if their ammo is upgraded enough. It's best to shoot the flat part of the turret, or get to their sides and pen them. However, if you can't do either of those, track them and hope that something bigger on your team will be able to take it out. The M93 can penetrate the front of the Tiger II (P), but not the H model.

在城市战中，你会想要与团队中的其他成员一同推进，但是，不要打头阵，因为你肯定会在道路的尽头发现令人讨厌的惊喜。当面对“虎王”坦克的时候，如果他们的弹药解锁到足够的程度（译者注：现在默认弹就行），它们可以360度无死角地击穿你的正面装甲，甚至是你最厚的区域(炮塔)。最好是射击炮塔的平面部分，或者去绕侧。然而，如果你不能做到这两点，那就追踪它们，并希望你的团队中有更大的东西能够解决它。M93可以击穿“虎王”坦克(P)的正面，但打不穿H型。

In open terrain, you can usually brawl from long-range with certain Tanks, such as the Tiger I, and mediums of Russia. However, if you see a Tiger II or other formidable opponent, it's best to stay far and show your front, angling the best. You can also use the hills to your advantage as most Tanks do, and hide behind them quickly moving out of cover, pot-shotting the enemy Tank then heading back into cover.

在开阔地带，你通常可以远程攻击某些坦克，比如“虎式”坦克和苏联中型坦克。然而，如果你看到一辆“虎王”坦克或其他强大的对手，最好呆远一点，露出你的正面，凑出最好的角度。你也可以像大多数坦克一样利用山丘，然后躲在它们后面快速移动出掩体，射击敌人的坦克，然后返回掩体。

In Arcade Battles you will usually see some pretty nasty Tanks, however, because of your turret and hull armour, you will be able to usually survive. Use the player-name system to your advantage and shoot enemy Tanks when they're not looking. However, because it's arcade and you're much more likely to be hit, it's best to angle your armour at a slightly less 35-degree angle. In AB, you will most likely have an advantage if you make the first shot, you're fast, and you never show your side.

在街机模式中，你常常会看到一些非常讨厌的坦克，但是，因为你靠谱的炮塔和车体装甲，你通常能够生存下来。利用玩家姓名系统，在敌人不注意的时候射击他们。然而，因为这是街机模式，你更有可能被击中，所以最好将你的装甲摆个不超过35度的小角度。在街机模式中，你很大概率能取得先手开火的机会，速战速决，别漏侧面。

In realistic battles and simulator battles, your opponents will be much more battle hardened and know where to shoot the Jumbo. When facing enemy Tanks, don't always suspect that you can just show your frontal armour and turret and expect to not get penetrated. As said before, be safe and be quick, and angle your armour when you can because that saves lives. You never want to go solo and move up on your own, as you will most definitely meet a Tank destroyer or quite possibly a heavy Tank. When meeting an IS-2, a turret hit or shot between the hull and turret will usually cripple it, but when facing a Tiger II you'll have to be a bit more careful, as the Tank is bigger and stronger than you. Although your M93 shot usually has the penetration power, it cannot penetrate the Tiger II's hull and your best luck will be shooting the flat armour of the turret front.

在历史模式和全真模式中，你的对手将更有战斗经验，知道在哪里攻击“酱爆”。当你面对敌人的坦克时，不要总是傻傻地以为你把正面摆正了就无敌了。就像之前说的，要既安全又迅速的尽可能按实际情况摆点儿角度，这样可以救你一命。你肯定不会想要独自推进，因为你很可能会遇到一辆坦克歼击车或是一辆重型坦克。当遇到IS-2的时候，打它炮塔或者炮塔和车体的连接处通常会将它瘫痪，但是当你面对“虎王”坦克时，你必须要小心一点，因为它比你更大更强。虽然你的M93炮弹穿深尚可，但它不能击穿“虎王”坦克的车体，你最好射击它的炮塔前部的平装甲带。

Tiger I E: This is a tough opponent to face, but, it can be killed quite easily if you know what to do. With the M62 round, you should aim at the area shown in the picture. It will penetrate the Tiger unless it is very sharply angled, but that could often mean that you can get a side shot. Do not aim for the drivers viewport or the machine gun, just aim for the flat armour on this section of the Tank.

“虎式”坦克E型：这是一个棘手的对手，但是，如果你知道怎么做，干掉它也不难。使用M62炮弹，你应该瞄准图片中显示的区域。它会击穿“虎式”坦克，除非它摆了个很刁钻的角度，但这通常意味着你可以抓住一个射击侧面的机会。不要瞄准驾驶员观察窗或机枪口，只瞄准坦克这部分的平直装甲。

Panther: This is another very common and tough opponent to face. Do not shoot for the hull front, it will not be able to penetrate. You can try to shoot the turret front, but there is a chance you will bounce. The most surefire way to disable a Panther is to shoot the commander's cupola, highlighted on the left. This will often kill the commander and gunner, and about half the time it will also kill the loader.

“豹式”坦克:这是另一个非常常见的棘手对手。不要射击它的车体正面，这是打不穿它的。你可以试着射击炮塔的正面，但是也有跳弹的风险。淦豹豹的最可靠的方法是射击左边凸起的车长指挥塔。这通常会杀死车长和炮手，大约半数时间它也会杀死装填手。

IS-2: This is one common opponent from the Soviet/Chinese tree. 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.

IS-2:这是一个来自苏联/中国的常见对手。它的122mm炮可以轻松穿透“巨无霸”，无论角度和距离如何。要摧毁它，就在它装填或没有意识到你的存在时向它射击。对于1943型，瞄准炮塔或者车体装甲的弯曲部分。它只有4个乘员，所以杀死所有炮塔乘员(3个，这很容易)就能摧毁它。对于1944型，只瞄准炮塔或车长指挥塔，因为它的车体非常硬。

Light Tank/SPAA: the Jumbo will be a very tough opponent for these light vehicles simply due to its thick armour. Use your good mobility and flank it whenever you can. Do not shoot at the turret at all times since it is 152 mm thick all-round, which is immune to almost all rounds from light vehicles. As you are at its side, target the lower part of the hull side where it is only 38 mm thick and can be penetrated by even low BR Tanks like M5A1. Penetrating shells through there will knock out all of its crew. Breaking its barrel or tracks can also be an option, but beware of its turning turret and roof mounted heavy MG. It might take several hits thus longer time to disable these modules, so retreat if there is danger.

轻坦/SPAA:对于这些轻型载具来说，巨无霸将是一个非常棘手的对手，因为它的装甲忒厚了。利用你良好的机动性，在任何可能的时候包抄它。不要一直对炮塔射击，因为它是152毫米厚的环形炮塔，几乎免疫轻型车辆的所有炮弹。当你在它的侧面时，瞄准车体侧面较低的部分，那里只有38毫米厚，甚至可以被像M5A1这样的低权重坦克击穿。击穿那里的炮弹会杀死所有乘员。淦它炮管或履带也是一个选择，但要注意，它的炮塔是可旋转的，提防一下它的车顶重机枪。摧毁“酱爆”可能需要好几轮打击，因此更长的时间来废掉上述模块，如果有危险的话，赶快溜。

Medium Tank: medium Tank commanders will have a better time dealing with an M4A3E2 as they are now better armed while also having adequate mobility to flank around. When the Jumbo is angling it is generally still impossible to penetrate. However if its angle is a bit too much and exposes more of its side, shells with good performance against sloped armour (eg. BR-365A) will easily go through the lower part of the hull side, right above the front sprocket wheel. If the engagement distance is very close and the Jumbo does not have bushes, you can probably see its famous weak spot: the MG port. Aim carefully at it, as it has a chance to bounce or absorb a shell. A penetration through there will usually destroy the target. At this close range, certain Tanks like T-34-85 and Panther A may not need to aim at the MG port, as they can punch straight through the upper front plate with ballistic capped shells or superior penetration.

中型坦克:中型坦克车长们将有更好的机会来对付M4A3E2，因为他们的武器更好，同时机动性也够用。当“巨无霸”摆角度时，一般还是不可能穿透它。然而，如果它的角度有点太大，暴露了更多的侧面，对倾斜装甲表现良好的炮弹(例如：BR-365A)将很容易从正前方的诱导轮位置击穿车体侧面较低的部分。如果接触距离非常近，而“酱爆”没有上伪装草，你可能会看到它著名的弱点：机枪口。小心瞄准它，因为它有机率跳弹或吞炮弹。击穿那里通常会摧毁“酱爆”。在很近的距离，某些坦克如T-34-85和“豹式”坦克A型，可能不需要瞄准机枪口，因为他们可以用风帽穿甲弹直接淦穿“酱爆”的首上。

Heavy Tank/Tank destroyer: since these heavier vehicles (eg. IS-2) generally come with extreme penetrations, there is not much to say. Target the M4A3E2's upper frontal plate if it is not angling. If it is, aim at the gun mantlet or lower side armour. Do not hit the weld line that joins the curved transmission housing with the flat upper front plate, it is very likely to absorb the shell.

重型坦克/坦克歼击车:因为这些重型车辆(例如：IS-2)通常都有很高的穿深，没什么好说的。如果M4A3E2没有摆角度，那就直接瞄准首上。如果它摆了角度，那就瞄准炮盾或侧面较低处。不要打弯曲的传动部分与首上连接处的焊缝，那里很可能会吞炮弹。

优点:

76毫米炮穿深能力相较75炮更好，特别是在解锁APCR后

重坦中装填最快的武器之一

-10度优秀俯角，在卖头作战时很有用

配备有稳定器，可以在低速时行进射击

“酱爆”的装甲布局增强了车体和炮塔的正面防护，尤其是在摆了角度时

车体正面的弱点很小，远距离很难命中

将加了水套防护的弹药集中存放于中间位置，减少了炮弹破片引发殉爆的机率

前进加速度较高，移动很快

缺点

会经常遇到能直接正面击穿自己的敌军坦克。

薄弱的侧面装甲会很容易地被敌军火炮击穿，从而空有厚实的正面装甲而不敢摆角度

由于正面的装甲是分层的，加之装甲重合机制，使得首上装甲不是很靠谱，因为它不能可靠地跳弹，即使档较小口径的75毫米SA50炮

在瞄准危险的敌方坦克时候，敌人同样可以射击你的平炮盾或炮盾上方较弱的区域，从而损坏主炮并杀死炮塔成员，或两者兼得

76毫米炮可能本身在对付敌人的正面装甲时有所欠缺，这就需要一些良好的射击位置和/或战术机动

车顶装甲很薄，一些垂直角度的灌顶攻击可以将其击穿

坦克太高了，这也导致他在战场上是个非常显眼的大目标

糟糕的越野机动性

相当低的最高速度35公里/小时，同样糟糕的倒车速度4公里/小时

发展

Long before D-Day, American war planners knew that it would a long and decisive battle against the German defensive and that the need for an assault Tank to push the lines and capture the beach was needed. The Americans knew they would need a Tank that was up-armoured and up-gunned, something beyond the standard M4 Sherman. The hope was the have the M26 Pershing finished by 1944, however, because of difficulties, it was delayed to 1945.

早在诺曼底登陆之前，美国的战争规划者就知道，这将是一场对抗德军的漫长而具有决定性的战役，他们需要一辆突击坦克来推进防线并占领海滩。美国人知道他们需要一辆厚装甲、高火力的坦克，而不是标准的M4谢尔曼坦克。他们希望M26潘兴在1944年完工，然而，由于种种困难，它被推迟到1945年才完工。

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.

美国军械部门随即把他们还在仓库里吃灰的M4谢尔曼大军分配了新的角色。尽管保持了相同的发动机，但装甲厚度从最初的76.2毫米增加到102毫米，与垂直方向成47度。这个角度将影响后来的谢尔曼设计，如M4A3通过改变原来的56度角倾斜与突出的乘员舱口到47度角倾斜没有任何突出从乘员舱口。修改后的M4谢尔曼装甲角度为150毫米视距(LOS)厚和180毫米有效。侧装甲也增加到76.2毫米厚，炮塔也重新设计以提供更多的防护。这些改良的谢尔曼被军械部命名为M4A3E2，而“巨无霸”这个绰号可能是战后起的。经过改装后，谢尔曼“巨无霸”重约42吨，速度降至每小时22英里。谢尔曼重量增加的一个缺点是谢尔曼的垂直蜗壳悬挂系统(VVSS)无法轻松承受重量，所以机组人员在操作时额外的小心，以免损坏悬挂。

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.

1944年3月，美国陆军订购了254辆这样的车辆，用于欧洲作战。它的目的是攻击诺曼底滩头阵地，在D日之后部署在诺曼底，以协助步兵突破德军防线。M4A3E2最初配备了75mm炮来支援步兵，与计划中的76毫米炮相比，它有更好的榴弹，但76毫米炮是在战役后期安装的，装备有76毫米炮的被称为M4A3E2 (76) W Jumbo。

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 a makeshift "'Expedient 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.

M4A3E2由于其优秀的防护，深受车组人员和指挥官的喜爱。尽管悬挂所承担的重量和压力变了，但“酱爆”的性能可靠，能够抗住会摧毁常规谢尔曼的攻击。在战争后期，当M4谢尔曼“巨无霸”的数量无法满足需求时，乔治·S·巴顿下令将现有的M4谢尔曼焊接上从被击毁的坦克中收集来的装甲板，作为临时的“巨无霸”。这导致新的谢尔曼，如M4A3 (76) W HVSS可以通过焊接金属到车体上来拥有有同样的防护。“巨无霸”在战争中的一次引人注目的表现是在巴顿的第三集团军中，它带头进攻巴斯通（Bastogne），以解救被困的第101师的伞兵。

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.

当欧洲战事结束时，M4A3E2被安置在美国本土，为登陆日本本土做准备。然而，随着1945年9月日本向美国投降，这一目标便未实现。在潘兴等重装甲坦克可以发挥作用前，M4A3E2谢尔曼被证明是一个非常有效的权宜之计。1948年，大约仍96辆“酱爆”在美国库存中。

为了准备解放欧洲，一辆以M4A3为基础改装的重装甲突击坦克被命名为M4A3E2 (76)W。1944年3月，武装部队委员会批准了一项改装254辆坦克的计划，其中一些坦克装备了76毫米炮。他们的装甲是通过在车体前部和两侧焊接38毫米装甲板来加强的。结果，正面装甲达到了102毫米，侧面装甲也达到了76毫米。变速箱用140毫米铸型罩保护，而车体的其余部分没有修改。新的T23炮塔有152毫米厚的装甲防护，特别之处在于它没有发射个人武器的舱口。178毫米厚的炮盾安装了一门76毫米M1A1C坦克炮，而弹药则以湿式方式储存。较厚的装甲使坦克的重量达到38吨，同时将其最高速度降低到35公里/小时。

装备有76毫米M1A1C炮的M4A2E2坦克的确切数量从未被确定。

由于德国反坦克炮无法穿透它们的正面装甲，这些坦克作为纵队先锋非常受美军欢迎。
