The American-made M4A4 tank is similar construction to the [[M4]] seen in the American tech tree, but fitted with an A57 Chrysler multi-bank engine. The larger engine design required a longer hull to hold it, resulting in the M4A4's elongated profile, as well as the wider spacings in between the suspension bogies. Otherwise, the utility of the M4A4 in the Chinese tech tree is no different than any other 75 mm armed M4 Sherman tanks.

The hull is very similar to the American [[M4|M4 Sherman]], with a 50.8 mm thick upper glacis and protruding hatches interrupting the glacis (augmented with applique armour). Weak spots here include the machine gun port and ventilator on the right side. The hull sides feature applique armour plates covering the ammunition storage racks. The turret is also very similar but lacks the applique armour on the right cheek, leaving a small weakened zone in that area. Frontal protection is quite good for its rank and shots from smaller anti-tank guns can generally be shrugged off, particularly when hull down. However more powerful guns such as the [[Pz.IV F2|Panzer IV F2's]] long 75mm can destroy the tank easily, so care should be taken. The side armour is only 38.1 mm thick and can be easily penetrated by just about any anti-tank gun, but the applique armour on this model can help if the tank is angled.

The hull is very similar to the American [[M4|M4 Sherman]], with a 50.8 mm thick upper glacis and protruding hatches interrupting the glacis (reinforced with appliqué armour). A weak spot is the radio antenna bulge on the machine gunner side. The hull sides feature appliqué armour plates covering the ammunition storage racks. The turret is also very similar but lacks the appliqué armour on the right cheek, leaving a small weakened zone in that area. Frontal protection is quite good for its rank and shots from smaller anti-tank guns can generally be shrugged off, particularly when hull down. However more powerful guns such as the [[Pz.IV F2]]'s long 75 mm can destroy the tank easily, so care should be taken. The side armour is only 38.1 mm thick and can be easily penetrated by just about any anti-tank gun if not angled.

Based on the chassis of the M4, the {{PAGENAME}} has the same good all-round mobility: the tank accelerates quickly and is able to reach a maximum speed of 44 km/h in a dozen of seconds. The brakes are powerful and will make the M4A4 skid rather than slow down when driving at maximum speed. The violent braking also causes the hull to wobble, making your targeting less accurate. The reverse speed is rather poor: it won't get you out of a dangerous situation quickly enough. The lack of neutral steering makes turning on the spot slow (2 km/h): make sure to build a little speed before turning and you'll turn much faster (11 km/h). Turning in reverse is equally slow (-2 km/h) Turning at full speed doesn't make you lose much speed as your acceleration is good. The offroad mobility is good: the {{PAGENAME}} reaches 16 km/h when fording, 17 km/h when driving uphill with some speed built-up but a mere 10 km/h uphill from a stop start. The tracks are large and grant you a decent mobility on hard (solid ground, roads) and soft terrain (mud, snow, sand). Light and medium obstacles (fences, posts, bushes and small trees) are not a problem but large obstacles will reduce your mobility: avoid them.

 +

The M4A4 only has a coaxial 7.62 mm machine gun and lacks the familiar pintle-mounted M2 Browning seen on other Sherman models. This makes fending off lightly-armoured and fast opponents like the [[Sd.Kfz.234/2 | Puma]] more difficult as the main gun must be used instead. The lone M1919A4 is also unlikely to do significant damage to incoming aircraft.

The M4 Sherman is an effective medium-range combat tank. Equipped with a fast-firing 75mm gun and with good handling characteristics, the M4 can be an extremely useful asset in most battles.
 +
 
 +
In battle the M4 performs well as an all-rounder; the thick turret front and 10 degrees of gun depression make the tank ideal for taking hull-down positions which protect the thinner hull armour from being penetrated by enemy fire. The sloped front upper glacis, when angled, also provides good protection against enemy fire. An unusual - and useful - difference is that the upper glacis is sloped at 56 degrees rather than the standard 45 degrees, making it more of a threat and more powerful due to improving the chances of a round ricochet. The only downfall may be the 2 crew member position in the front that protrudes out to form a flat surface, but both are covered with an additional 20 mm plate. The reasonable mobility of the Sherman makes flanking a viable tactic. The main weakness of the M4 is the side armour - not only is it vertical and thin, but behind it most of the ammunition is stowed. The tall silhouette of the tank also makes finding suitable cover difficult. Overall, the M4 Sherman can be considered as an armoured jack-of-all-trades - it will serve a tanker well, however it will not excel in any particular role.
 +
 
 +
In battle, try to use terrain as cover. Hull-down positions are especially strong in the M4 Sherman, as it has a good 10 degrees of gun depression. The gun mantlet and turret are reasonably strong, but avoiding shots is still the best strategy. In this respect, a hull-down position hides the vulnerable hull. If this is not available, then angling the hull armour to present a greater slope is often a good idea, as this can bounce some low-powered cannon at any range and at longer ranges, render the hull impenetrable.
 +
 
 +
Another way to play the M4 Sherman is to tap into its traditional cavalry role, its mobility. The M4 Sherman is a great flanker as it is fast enough to get the jump on the enemy's side. Defeat the enemy at their weak front lines or go around the entire enemy force. Once in position at their sides or rear, ambush them. Ideally, the enemy should be too busy focusing on allies attacking in the front to notice the M4 instantly. Take out the weaker light or medium tanks, the 75 mm gun is not very ideal against heavy tanks like the [[KV-1 (L-11)|KV-1]] so take out its friends to allow allies more room to outmanoeuvre the KV tank. An organized attack will increase the M4 chances on the battlefield and success.
 +
 
 +
Compared to the contemporary [[T-34 (1943) (China)|T-34 (1943)]] in the PLA line of the Chinese tree, the M4A4 has worse mobility but enjoys vastly improved gun handling. They are good complements to each other, as the T-34 excels in fast, aggressive attacks while the M4A4 is good for methodical pushes and hull-down scenarios.
 +
 
 +
'''Enemies worth noting:'''
 +
 
 +
[[M4A2]] / [[M4A4 (1st PTG)|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 75mm gun, their hull can be almost impossible to penetrate when angled, hull down or 300m away. For a M4A4, there are 2 apparent bulges on the upper front plate, a penetration through there is a guaranteed kill most of the times. But in case the opponent covers them up or when it's a M4A2, aim for the middle parts of the gun mantlet or the turret armor unprotected by the mantlet, you can at least make them defenseless. Note that their guns are equally weak against you, so wiggle around to disrupt their aim while you reload, you have a good chance of bouncing some shells.
 +
 
 +
[[KV I C 756 (r) (Germany)|KV I C 756 (r)]]:
 +
 
 +
A vehicle that the M4 Sherman will have trouble against is this German KV-1. While the [[KV-1 (L-11)|L-11]] is underpowered, the [[KV-1 (ZiS-5)|ZiS-5]] is potent enough to punch through the Sherman's front, and the Sherman is unable to penetrate the KV-1's thick armour especially with its dd-on armor plates. If this heavy tank is encountered and if it's angling the hull, aim at the gun mantlet as it is only 50mm thick. You can knock out its gunner easily. Or shoot at the thin copula, there's also some chance to kill the gunner. Of course, the best way is to shoot at its sides and rear without any angle, where its armour is unsloped, though it will still have to be at a close range to penetrate the armour. In addition, shots to the sides will most likely hit fuel tanks or ammunition storage, causing a fire or ammunition detonation and at best, time to reassess the situation.
 +
 
 +
[[Churchill Mk I]], [[Churchill Mk III]], [[Pz.Kpfw. Churchill (Germany)|Pz.Kpfw. Churchill]]:
 +
 
 +
The Churchills, with their complex hulls and sturdy turrets, can be quite hard to kill at range. Again, maneuver as close to them as possible, the idea distance being no more than 200m. 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 89mm. 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 armor, 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 Shermans biggest threats at this rank. The long barrel 75mm 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 80mm, which will be much harder to penetrate with the APCBC over 500m. Luckily the turret armour remains the same at 50mm. Either aim here with APCBC or sacrifice damage potential and use the AP round to penetrate the hull.
 +
 
 +
[[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 75mm 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 kill 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 one-shot this vehicle. With the G variant, it is more reliable to use AP at ranges within 500m to ensure penetration.

'''Cons:'''
* Large profile
+
 
* Has some weak points
+
* Large profile and weak side armour; flankers like the Sd.kfz.234/2 can easily see and penetrate it
 +
* Frontal armour is still inadequate, will get frontally penetrated and one-shot by tanks like [[Pz.IV F2]] / G, [[StuG III F]] / G, [[M10 (Family)|M10]]
 +
* The best M61 shell struggles to penetrate heavy targets like [[StuG III G]], Churchill Mk.III or even the T-34 and M10 when angled
 +
* Trajectory is curved and velocity is low due to its short barrel, thus distant/moving targets are hard to shoot at
 +
* Hull traverse is quite slow, making it sluggish in a turn. Also the narrow tracks offer poor ground flotation, thus poor off-road capabilities. Can only reach its top speed on paved or hard surfaces
 +
* Lack of M2 Browning machine gun seen on most other Shermans means anti-aircraft defense is weak
 +
* Roof armour of 19.5 mm thick is vulnerable to airstrikes with AP cannons. For example the widely used [[M2 Browning (12.7 mm)|M2 Browning]]

Description

The ␗Medium Tank M4A4 Sherman is a rank II Chinese medium tank with a battle rating of 3.7 (AB/RB/SB). It was introduced in Update 1.91 "Night Vision".

The American-made M4A4 tank is similar construction to the M4 seen in the American tech tree, but fitted with an A57 Chrysler multi-bank engine. The larger engine design required a longer hull to hold it, resulting in the M4A4's elongated profile, as well as the wider spacings in between the suspension bogies. Otherwise, the utility of the M4A4 in the Chinese tech tree is no different than any other 75 mm armed M4 Sherman tanks.

Notes:

  • Suspension wheels are 15 mm thick while tracks are 20 mm thick and bogies are 10 mm thick.
  • The belly of the tank is 12.7 mm thick.
  • The internal wall separating the crew compartment from the engine bay is 9.5 mm thick.

The hull is very similar to the American M4 Sherman, with a 50.8 mm thick upper glacis and protruding hatches interrupting the glacis (reinforced with appliqué armour). A weak spot is the radio antenna bulge on the machine gunner side. The hull sides feature appliqué armour plates covering the ammunition storage racks. The turret is also very similar but lacks the appliqué armour on the right cheek, leaving a small weakened zone in that area. Frontal protection is quite good for its rank and shots from smaller anti-tank guns can generally be shrugged off, particularly when hull down. However more powerful guns such as the Pz.IV F2's long 75 mm can destroy the tank easily, so care should be taken. The side armour is only 38.1 mm thick and can be easily penetrated by just about any anti-tank gun if not angled.

Based on the chassis of the M4, the M4A4 (China) has the same good all-round mobility: the tank accelerates quickly and is able to reach a maximum speed of 44 km/h in a dozen of seconds. The brakes are powerful and will make the M4A4 skid rather than slow down when driving at maximum speed. The violent braking also causes the hull to wobble, making your targeting less accurate. The reverse speed is rather poor: it won't get you out of a dangerous situation quickly enough. The lack of neutral steering makes turning on the spot slow (2 km/h): make sure to build a little speed before turning and you'll turn much faster (11 km/h). Turning in reverse is equally slow (-2 km/h) Turning at full speed doesn't make you lose much speed as your acceleration is good. The offroad mobility is good: the M4A4 (China) reaches 16 km/h when fording, 17 km/h when driving uphill with some speed built-up but a mere 10 km/h uphill from a stop start. The tracks are large and grant you a decent mobility on hard (solid ground, roads) and soft terrain (mud, snow, sand). Light and medium obstacles (fences, posts, bushes and small trees) are not a problem but large obstacles will reduce your mobility: avoid them.

Notes:

  • To go into battle with the turret basket empty of ammo, pack 79 (+19) shells (racks 1 to 4 emptied).
  • To go into battle with the turret basket and the flanks empty of ammo, pack 31 (+67) shells (racks 1 to 7 emptied).
  • The 8th rack is large and located in a weak spot: the bottom section of the armor. In case of penetration, there is a high risk of ammo rack detonation. Make sure not to expose your flanks unnecessarily.

The M4A4 only has a coaxial 7.62 mm machine gun and lacks the familiar pintle-mounted M2 Browning seen on other Sherman models. This makes fending off lightly-armoured and fast opponents like the Puma more difficult as the main gun must be used instead. The lone M1919A4 is also unlikely to do significant damage to incoming aircraft.

Usage in battles

The M4 Sherman is an effective medium-range combat tank. Equipped with a fast-firing 75mm gun and with good handling characteristics, the M4 can be an extremely useful asset in most battles.

In battle the M4 performs well as an all-rounder; the thick turret front and 10 degrees of gun depression make the tank ideal for taking hull-down positions which protect the thinner hull armour from being penetrated by enemy fire. The sloped front upper glacis, when angled, also provides good protection against enemy fire. An unusual - and useful - difference is that the upper glacis is sloped at 56 degrees rather than the standard 45 degrees, making it more of a threat and more powerful due to improving the chances of a round ricochet. The only downfall may be the 2 crew member position in the front that protrudes out to form a flat surface, but both are covered with an additional 20 mm plate. The reasonable mobility of the Sherman makes flanking a viable tactic. The main weakness of the M4 is the side armour - not only is it vertical and thin, but behind it most of the ammunition is stowed. The tall silhouette of the tank also makes finding suitable cover difficult. Overall, the M4 Sherman can be considered as an armoured jack-of-all-trades - it will serve a tanker well, however it will not excel in any particular role.

In battle, try to use terrain as cover. Hull-down positions are especially strong in the M4 Sherman, as it has a good 10 degrees of gun depression. The gun mantlet and turret are reasonably strong, but avoiding shots is still the best strategy. In this respect, a hull-down position hides the vulnerable hull. If this is not available, then angling the hull armour to present a greater slope is often a good idea, as this can bounce some low-powered cannon at any range and at longer ranges, render the hull impenetrable.

Another way to play the M4 Sherman is to tap into its traditional cavalry role, its mobility. The M4 Sherman is a great flanker as it is fast enough to get the jump on the enemy's side. Defeat the enemy at their weak front lines or go around the entire enemy force. Once in position at their sides or rear, ambush them. Ideally, the enemy should be too busy focusing on allies attacking in the front to notice the M4 instantly. Take out the weaker light or medium tanks, the 75 mm gun is not very ideal against heavy tanks like the KV-1 so take out its friends to allow allies more room to outmanoeuvre the KV tank. An organized attack will increase the M4 chances on the battlefield and success.

Compared to the contemporary T-34 (1943) in the PLA line of the Chinese tree, the M4A4 has worse mobility but enjoys vastly improved gun handling. They are good complements to each other, as the T-34 excels in fast, aggressive attacks while the M4A4 is good for methodical pushes and hull-down scenarios.

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 75mm gun, their hull can be almost impossible to penetrate when angled, hull down or 300m away. For a M4A4, there are 2 apparent bulges on the upper front plate, a penetration through there is a guaranteed kill most of the times. But in case the opponent covers them up or when it's a M4A2, aim for the middle parts of the gun mantlet or the turret armor unprotected by the mantlet, you can at least make them defenseless. Note that their guns are equally weak against you, so wiggle around to disrupt their aim while you reload, you have a good chance of bouncing some shells.

KV I C 756 (r):

A vehicle that the M4 Sherman will have trouble against is this German KV-1. While the L-11 is underpowered, the ZiS-5 is potent enough to punch through the Sherman's front, and the Sherman is unable to penetrate the KV-1's thick armour especially with its dd-on armor plates. If this heavy tank is encountered and if it's angling the hull, aim at the gun mantlet as it is only 50mm thick. You can knock out its gunner easily. Or shoot at the thin copula, there's also some chance to kill the gunner. Of course, the best way is to shoot at its sides and rear without any angle, where its armour is unsloped, though it will still have to be at a close range to penetrate the armour. In addition, shots to the sides will most likely hit fuel tanks or ammunition storage, causing a fire or ammunition detonation and at best, time to reassess the situation.

Churchill Mk I, Churchill Mk III, Pz.Kpfw. Churchill:

The Churchills, with their complex hulls and sturdy turrets, can be quite hard to kill at range. Again, maneuver as close to them as possible, the idea distance being no more than 200m. 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 89mm. 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 armor, 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 Shermans biggest threats at this rank. The long barrel 75mm 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 80mm, which will be much harder to penetrate with the APCBC over 500m. Luckily the turret armour remains the same at 50mm. Either aim here with APCBC or sacrifice damage potential and use the AP round to penetrate the hull.

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 75mm 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 kill 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 one-shot this vehicle. With the G variant, it is more reliable to use AP at ranges within 500m to ensure penetration.

Pros and cons

Pros:

  • Excellent gun depression of -10° plus the angled frontal turret allows it to utilise hills very well
  • Great penetration and post-penetration damage when using M61 shells; can frontally penetrate and one-shot most opponents like the Pz.IV F2, Chi-Nu and StuG III F
  • Great turret traverse speed allows it to deal with multiple threats easily
  • Adequate top speed allows it to get to positions in time, or to do tactical manoeuvres like flanking
  • 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:

  • Large profile and weak side armour; flankers like the Sd.kfz.234/2 can easily see and penetrate it
  • Frontal armour is still inadequate, will get frontally penetrated and one-shot by tanks like Pz.IV F2 / G, StuG III F / G, M10
  • The best M61 shell struggles to penetrate heavy targets like StuG III G, Churchill Mk.III or even the T-34 and M10 when angled
  • Trajectory is curved and velocity is low due to its short barrel, thus distant/moving targets are hard to shoot at
  • Hull traverse is quite slow, making it sluggish in a turn. Also the narrow tracks offer poor ground flotation, thus poor off-road capabilities. Can only reach its top speed on paved or hard surfaces
  • Lack of M2 Browning machine gun seen on most other Shermans means anti-aircraft defense is weak
  • Roof armour of 19.5 mm thick is vulnerable to airstrikes with AP cannons. For example the widely used M2 Browning

History

The product of a production shortage of Ford GAA V8 engines, the M4A4 instead used the Chrysler A57 multibank. Due to the much more complex maintenance that the engine required, the A4 was unpopular with American mechanics and nearly all models were sent to the British, Soviets, and Chinese.
