The [[M3 Stuart]] light tank was developed from the [[M2A4]], incorporating many improvements to the design such as a trailing idler suspension. Additional enhancements were soon implemented, primarily a new turret that came with new gun stabilizers, hydraulic turret traverse mechanism, and a turret basket for the turret crew, and the new design was named the M3A1 Stuart in 1941. The M3A1 gradually replaced the M3 light tanks in service, including in the United States Marine Corps (USMC), which received them in 1942. The M3A1 would serve in the USMC during their various Pacific Campaigns against the Japanese until the end of World War II. One modification performed by the USMC in 1944 was a flamethrower tank, which used 24 M3A1 and attached a flame gun in the hull machine gun position. These modified M3A1 were nicknamed "Satan" and were used in the various battles in the Marianas.
The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} American light 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"]] and is essentially identical to the [[M3A1 Stuart|M3A1]] in the tech tree. The M3A1 USMC is available in the US Beginner's Pack on the Gaijin Store.

The '''{{Specs|name}}''' was first introduced with the American ground tree in [[Update 1.45 "Steel Generals"]], and is available in the US Starter Pack on the Gaijin Store. The tank, performance-wise, is the same as the [[M3A1 Stuart]] in the tech tree in a unique camouflage scheme. As such, the M3A1 continues to show great mobility as characteristic of a light tank. While the 37 mm may seem anemic at its battle rating, it can still attack through enemy weak points, encouraging a gameplay of caution to wait for the right opportunity to catch the enemy off-guard on its flank as they either pass by the Stuart without noticing it, or are preoccupied with other allies.

Being a light tank the M3A1 has fairly thin armour, it can generally protect against most machine guns and some smaller (20 mm) cannons, but will usually not stand up against the main weapons of most enemy tanks at its BR. There is a fair amount of empty space inside the tank, this means that some poorly placed shots can go through your tank without causing much damage.

The M3A1 (USMC) has competitive mobility with a ratio of 20.8 hp per ton. At lower speeds (5-10 km/h) the turning can feel rather sluggish, but once a bit of forward movement is applied and the speed is increased the turning will feel much smoother and faster. The forward drive of the M3A1 (USMC) can max out at 47 km/h off road and 58 km/h on road which will usually allow you to reach capture points or desirable camping spots quickly. The -6 km/h reverse speed of the M3A1 (USMC) is certainly usable in most situations.

The main weapon on the M3A1 is a 37 mm M6 cannon featuring two rounds, AP and APCBC. This is a fairly standard gun for early American tanks as it is also featured on the [[M5A1]], [[M22]] & [[LVT(A)(1)]] although some of these vehicles also include a HE round that the M3A1 lacks. This gun packs a fierce punch if aiming at the correct area and firing at the correct distance. It is a small calibre fast-firing gun with a maximum penetration of 84 mm at 100 m (M51B1/B2 shell), being able to penetrate most of the opponents it will face. The penetration power and gun accuracy drop a lot beyond 500 m and become unreliable past 700 m. The gun is equipped with a vertical stabiliser, giving the M3A1 Stuart a huge advantage in some cases as you can fire precisely while moving, but keep in mind that it activates only when the tank is driving under 10 km/h.

While it lacks the post-penetration damage to disable most enemies in one shot, it can quickly finish them off with its fast reload. Knowledge of enemy vehicle layouts is essential with ammunition lacking post-penetration explosive damage. Make sure to target modules and crew positions to maximise the damage. Disabling the enemy gunner on your first shot will be critical to win engagements as you'll most likely need several shots to destroy an enemy vehicle.

Due to its light armour it is advisable not to use the M3A1 frontally at closer ranges, especially not against higher ranked enemy vehicles that will go through your strongest frontal armour (50.8 mm) without issue. The ideal tactic to use is to employ your competitive speed to flank the enemy and find a position that will allow you to attack them with little resistance. Even in a match against higher ranked enemy vehicles your rounds will have no issue going through the side armour of said enemy vehicles, common maps such as [[Eastern Europe (Ground Forces)|Eastern Europe]] and [[Cargo Port]] offer clear opportunities to flank the enemy vehicles with good amounts of cover. This is especially clear on [[Eastern Europe (Ground Forces)|Eastern Europe]] where you can flank on the other side of the river that runs through the map, this puts you at close range to the side of enemy vehicles, allowing you to prevent them reaching capture points such as the central B point.

To take down enemy vehicles it is advisable to destroy both their turret and engine to prevent escape and stop them engaging you or your allies, due to the fast reload (at best 2.9s) you can hit both parts of an enemy quickly, usually before they can fire back. If they are still not dead after the gun and engine have been hit, shots into the crew compartment should finish the job, but most enemy's are usually killed by the first 2 shots. It is common for any side shot against an enemy to penetrate and cause a fair level of damage, even if the enemy is not killed, your fast reload will grant you a second chance quickly to place an adjusted shot into the enemy. Even at longer ranges the M3A1 can be a competent sniper, especially if facing lighter vehicles with flat armour or the side armour of a targeted enemy, firing from long range is another way to ensure that your light armour does not hold you back, being at long range will usually prevent or make it difficult for enemy's to successfully hit your vehicle.

Specific enemy vehicles that bear mentioning are firstly any Germans with the [[KwK38 (20 mm)|20 mm KwK/FlaK38]] cannon, this gun might be small but can have up to 64 mm of pen, which is enough to go through the M3A1 almost anywhere. These guns can also fire 10 rounds at 280 rounds/min before having to reload the clip, meaning that they will very easily take out your crew before you have a chance to respond. To counter, the best chance you have is to angle your frontal armour which can make it difficult for the PzGr 40 rounds to penetrate. The Russian [[T-50]] and [[T-126]] are vehicles you will also see commonly, these have fairly thick and angled frontal armour that will prevent you from easily getting through. These tanks can also carry an APHEBC round that will destroy you in one shot with little difficulty, to counter you should use your speed to attempt to get a side shot into either the turret or engine. If the T-50 cannot move you can outrun its turret and finish it without much difficulty.

Specific enemy vehicles that bear mentioning are firstly any Germans with the 20 mm [[KwK38 (20 mm)|KwK38]] or [[FlaK38 (20 mm)|FlaK38]] cannons, these guns might be small in calibre but can have up to 48 mm of penetration, which is enough to go through the M3A3. Combined with a rate of fire of 280 rounds per minute, and a very short reload time, these guns will very easily take out your crew before you have a chance to respond.

It is likely that the M3A1 will encounter some rough heavies, like the [[Matilda III]] and the [[B1 bis]]. The best tactic against these types of targets is to use the M3A1's fast speed, get within 200 m from them and attack, with shooting at point-blank range being the most effective way. Before conducting an attack, check the M3A1's and the enemy's surroundings to make sure no one will ambush the M3A1. While charging, use the M3A1's quick turns to suddenly change direction to avoid being shot if they are aiming and firing at the M3A1. Once the tank is at the ideal distance, manoeuvre so that the gun is perpendicular to their armour. Do not shoot if the enemy is angling! The small calibre 37 mm gun is very likely to bounce off or not penetrate against sloped armour.

For the Matilda III, shoot at the middle of the near-vertical frontal plate to knock out the driver first, since the 37 mm shell is not enough to knock out the gunner after penetrating. Once it is immobile, go to its side and finish it by shooting its hull sides. Or, shoot the right side of the gun mantlet to disable its gunner. For best chance of penetration, do not shoot its turret side.

For the B1, either aim for the near-vertical frontal armour plate at the right side of the hull, or the turret ring to incapacitate the commander/gunner, or simply move to its side and knock out the crews one by one by hitting its flat side armour.

The British were the first to use the M3 ''Stuart'' in Africa in 1941, using it in Operation Crusader. However, the result ended with heavy losses, due to the better training the German Afrika Korps had compared to the British tank doctrine. The encounter also pointed out many flaws in the M3, mainly the cramped interior and limited operational range, but was praised for its high mobility and reliability when compared to the British contemporary designs. In 1942, the ''Stuarts'' were generally kept as recon units rather than combat units, and some were even modified to improve speed and range by removing the turret, and others were converted to armoured personnel carriers and command vehicles. Though the British used it extensively, it was still in small proportion compared to American usage. The Soviet Union was also another user of the M3 but found it unfavourable due to their own logistics, plus it was not made to withstand the Russian ''[[wikipedia:Rasputitsa|Rasputitsa]]'' or even the winter. The Soviet eventually turned down any more offers for the ''Stuart'' by 1943. The M3s also supported the British and Chinese forces in Asia against the Japanese Army, and also France and Yugoslavia in Europe against the German Wehrmacht.

The Americans used it widely in both operational theatres. In the Pacific, the M3s were the first tanks America used in a tank vs. tank operation against the Imperial Japanese Army, where five M3s fought [[Ha-Go|Type 95 Ha-Gos]] in the Phillippines. Though the ''Stuarts'' were newer than the Japanese tank designs by about five years, they were seen as equal in performance and firepower, but the M3 benefited by the support of the American industry arm. The ''Stuarts'' served in the Pacific slightly better than its heavier counterparts such as the [[M4|M4 ''Shermans'']] due to its lighter weight and manoeuvrability in the poor jungle terrain, but the M3 ''Stuarts'' in the Pacific were gradually replaced by M4 ''Shermans'' due to heavy losses from its thinner armour. The M3 was also some of the first US tanks to be converted into flamethrower tanks, named as the ''"Satan"''. The Satan tanks provided favourable results to the concept of a flamethrower tank and were replaced by flamethrower-equipped M4 ''Shermans'' in 1945.

In Europe, the M3 formed a large part of the American tank battalions, though following the British path by sidelining the ''Stuarts'' from combat duties after heavy losses and to serve alongside ''Shermans'' as scouting units. A typical tank battalion for the US Army consisted of three companies of ''Shermans'' and one of ''Stuarts''. Other than scouting, the M3s were also used in cavalry roles and infantry support since their cannon are unable to compete with the German tank designs. Despite their dwindling capabilities in battle, the M3 was kept in service up until the end of the war due to the large production numbers.

After World War II, the ''Stuarts'' were given out as cheap surplus, countries such as China, India, and Pakistan picked up a few and used them in their conflicts. Portuguese also picked up a few M3s for the war in Angola, and the South African Corps continued using the ''Stuarts'' until 1955, where some were still kept in service until 1968 due to available parts. Today, Paraguay is still a user of the M3 light tanks, though as the only tracked armour used in the country.

The ''Stuart'' light tank design was also quite versatile that it was made into different variants for different roles on the battlefield. It served as an infantry support vehicle as to the ''[[M8 Scott|75 mm GMC M8]]'' and experiments were also taken to see if it could be adapted to an anti-aircraft gun and a flamethrower as well. However, the M3 was becoming an ageing design with inferior armour, cramped interior layout, and a small 37 mm gun, so a program to replace the light tank began in 1943 and became the [[M24|M24 ''Chaffee'']], which would eventually replace the M3 Light Tank mostly after World War II.

Production of the M3A1 Stuart modification got underway in April 1942, with its primary changes affecting turret construction. The turret was a horseshoe-shaped M3, though it did not have a cupola, and two triangular hatches on its roof served as exits for the crew. The gunner and reloader had periscopes. The turret rotated using a power traverse as opposed to the manually rotated M3. Its faster rotation speed required changes in its construction, in particular a basket fitted with seats for the crew members.

Description

The M3 Stuart light tank was developed from the M2A4, incorporating many improvements to the design such as a trailing idler suspension. Additional enhancements were soon implemented, primarily a new turret that came with new gun stabilizers, hydraulic turret traverse mechanism, and a turret basket for the turret crew, and the new design was named the M3A1 Stuart in 1941. The M3A1 gradually replaced the M3 light tanks in service, including in the United States Marine Corps (USMC), which received them in 1942. The M3A1 would serve in the USMC during their various Pacific Campaigns against the Japanese until the end of World War II. One modification performed by the USMC in 1944 was a flamethrower tank, which used 24 M3A1 and attached a flame gun in the hull machine gun position. These modified M3A1 were nicknamed "Satan" and were used in the various battles in the Marianas.

The Light Tank M3A1 Stuart (USMC) was first introduced with the American ground tree in Update 1.45 "Steel Generals", and is available in the US Starter Pack on the Gaijin Store. The tank, performance-wise, is the same as the M3A1 Stuart in the tech tree in a unique camouflage scheme. As such, the M3A1 continues to show great mobility as characteristic of a light tank. While the 37 mm may seem anemic at its battle rating, it can still attack through enemy weak points, encouraging a gameplay of caution to wait for the right opportunity to catch the enemy off-guard on its flank as they either pass by the Stuart without noticing it, or are preoccupied with other allies.

Being a light tank the M3A1 (USMC) has fairly thin armour, it can generally protect against most machine guns and some smaller (20 mm) cannons, but will usually not stand up against the main weapons of most enemy tanks at its BR. There is a fair amount of empty space inside the tank, this means that some poorly placed shots can go through your tank without causing much damage.

Demonstration of the slow and fast turning of the M3A1

The M3A1 (USMC) has competitive mobility with a ratio of 20.8 hp per ton. At lower speeds (5-10 km/h) the turning can feel rather sluggish, but once a bit of forward movement is applied and the speed is increased the turning will feel much smoother and faster. The forward drive of the M3A1 (USMC) can max out at 47 km/h off road and 58 km/h on road which will usually allow you to reach capture points or desirable camping spots quickly. The -6 km/h reverse speed of the M3A1 (USMC) is certainly usable in most situations.

Main article: M6 (37 mm)

The main weapon on the M3A1 (USMC) is a 37 mm M6 cannon featuring two rounds, AP and APCBC. This is a fairly standard gun for early American tanks as it is also featured on the M5A1, M22 & LVT(A)(1) although some of these vehicles also include a HE round that the M3A1 (USMC) lacks. This gun packs a fierce punch if aiming at the correct area and firing at the correct distance. It is a small calibre fast-firing gun with a maximum penetration of 84 mm at 100 m (M51B1 shell), being able to penetrate most of the opponents it will face. The penetration power and gun accuracy drop a lot beyond 500 m and become unreliable past 700 m. The gun is equipped with a vertical stabiliser, giving the M3A1 (USMC) a huge advantage in some cases as you can fire precisely while moving, but keep in mind that it activates only when the tank is driving under 10 km/h.

While it lacks the post-penetration damage to disable most enemies in one shot, it can quickly finish them off with its fast reload. Knowledge of enemy vehicle layouts is essential with ammunition lacking post-penetration explosive damage. Make sure to target modules and crew positions to maximise the damage. Disabling the enemy gunner on your first shot will be critical to win engagements as you'll most likely need several shots to destroy an enemy vehicle.

Usage in battles

Due to its light armour it is advisable not to use the M3A1 (USMC) frontally at closer ranges, especially not against higher ranked enemy vehicles that will go through your strongest frontal armour (50.8 mm) without issue. The ideal tactic to use is to employ your competitive speed to flank the enemy and find a position that will allow you to attack them with little resistance. Even in a match against higher ranked enemy vehicles your rounds will have no issue going through the side armour of said enemy vehicles, common maps such as Eastern Europe and Cargo Port offer clear opportunities to flank the enemy vehicles with good amounts of cover. This is especially clear on Eastern Europe where you can flank on the other side of the river that runs through the map, this puts you at close range to the side of enemy vehicles, allowing you to prevent them reaching capture points such as the central B point.

To take down enemy vehicles it is advisable to destroy both their turret and engine to prevent escape and stop them engaging you or your allies, due to the fast reload you can hit both parts of an enemy quickly, usually before they can fire back. If they are still not dead after the gun and engine have been hit, shots into the crew compartment should finish the job, but most enemy's are usually killed by the first 2 shots. It is common for any side shot against an enemy to penetrate and cause a fair level of damage, even if the enemy is not killed, your fast reload will grant you a second chance quickly to place an adjusted shot into the enemy. Even at longer ranges the M3A1 (USMC) can be a competent sniper, especially if facing lighter vehicles with flat armour or the side armour of a targeted enemy, firing from long range is another way to ensure that your light armour does not hold you back, being at long range will usually prevent or make it difficult for enemy's to successfully hit your vehicle.

Enemies worth noting:

Specific enemy vehicles that bear mentioning are firstly any Germans with the 20 mm KwK38 or FlaK38 cannons, these guns might be small in calibre but can have up to 48 mm of penetration, which is enough to go through the M3A3. Combined with a rate of fire of 280 rounds per minute, and a very short reload time, these guns will very easily take out your crew before you have a chance to respond. To counter these opponents, the best chance you have is to angle your frontal armour which can make it difficult for their PzGr 40 HVAP-T rounds to penetrate. The Russian T-50 and T-126 are vehicles you will also see commonly, these have fairly thick and angled frontal armour that will prevent you from easily getting through. These tanks can also carry an APHEBC round that will destroy you in one shot with little difficulty, to counter you should use your speed to attempt to get a side shot into either the turret or engine. If the T-50 cannot move you can outrun its turret and finish it without much difficulty.

It is likely that the M3A1 (USMC) will encounter some rough heavies, like the Matilda III and the B1 bis. The best tactic against these types of targets is to use the M3A1 (USMC)'s fast speed, get within 200 m from them and attack, with shooting at point-blank range being the most effective way. Before conducting an attack, check the M3A1 (USMC)'s and the enemy's surroundings to make sure no one will ambush the M3A1 (USMC). While charging, use the M3A1 (USMC)'s quick turns to suddenly change direction to avoid being shot if they are aiming and firing at the M3A1 (USMC). Once the tank is at the ideal distance, manoeuvre so that the gun is perpendicular to their armour. Do not shoot if the enemy is angling! The small calibre 37 mm gun is very likely to bounce off or not penetrate against sloped armour.

For the Matilda III, shoot at the middle of the near-vertical frontal plate to knock out the driver first, since the 37 mm shell is not enough to knock out the gunner after penetrating. Once it is immobile, go to its side and finish it by shooting its hull sides. Or, shoot the right side of the gun mantlet to disable its gunner. For best chance of penetration, do not shoot its turret side.

For the B1, either aim for the near-vertical frontal armour plate at the right side of the hull, or the turret ring to incapacitate the commander/gunner, or simply move to its side and knock out the crews one by one by hitting its flat side armour.

Pros and cons

Pros:

  • Great cannon with good penetration, excellent rate of fire and gun depression; it can effectively penetrate common opponents like the Pz.II and Chi-Ha, as well as heavy targets like the B1 bis or Matilda III
  • Excellent acceleration, top speed and turning ability on all terrains; easily outruns slower opponents like the Pz.III
  • Access to a vertical stabiliser which most tanks don't have, it is an advantage in close quarter encounters
  • Respectable frontal armour that, if angled, might bounce some shells from a distance (e.g. Japanese 37 mm/German 20 mm)
  • Small turret profile makes it harder to get hit when hull-down
  • Empty space below the turret crew can absorb poorly aimed shots, they tend to not do much damage
  • Comes with "USMC" decal

Cons:

  • Weak armour against high-penetration shells like 50 mm KwK39 or 76 mm F-34
  • Its shells do not have explosive filler, severely limiting the post-penetration effect especially against spacious tanks like the LVT(A)(1)
  • Inefficient brakes when trying to stop the tank at full speed
  • Hull is fairly tall for a light tank and the crews are closely packed, reducing its survivability

History

The British were the first to use the M3 Stuart in Africa in 1941, using it in Operation Crusader. However, the result ended with heavy losses, due to the better training the German Afrika Korps had compared to the British tank doctrine. The encounter also pointed out many flaws in the M3, mainly the cramped interior and limited operational range, but was praised for its high mobility and reliability when compared to the British contemporary designs. In 1942, the Stuarts were generally kept as recon units rather than combat units, and some were even modified to improve speed and range by removing the turret, and others were converted to armoured personnel carriers and command vehicles. Though the British used it extensively, it was still in small proportion compared to American usage. The Soviet Union was also another user of the M3 but found it unfavourable due to their own logistics, plus it was not made to withstand the Russian Rasputitsa or even the winter. The Soviet eventually turned down any more offers for the Stuart by 1943. The M3s also supported the British and Chinese forces in Asia against the Japanese Army, and also France and Yugoslavia in Europe against the German Wehrmacht.

The Americans used it widely in both operational theatres. In the Pacific, the M3s were the first tanks America used in a tank vs. tank operation against the Imperial Japanese Army, where five M3s fought Type 95 Ha-Gos in the Philippines. Though the Stuarts were newer than the Japanese tank designs by about five years, they were seen as equal in performance and firepower, but the M3 benefited by the support of the American industry arm. The Stuarts served in the Pacific slightly better than its heavier counterparts such as the M4 Shermans due to its lighter weight and manoeuvrability in the poor jungle terrain, but the M3 Stuarts in the Pacific were gradually replaced by M4 Shermans due to heavy losses from its thinner armour. The M3 was also some of the first US tanks to be converted into flamethrower tanks, named as the "Satan". The Satan tanks provided favourable results to the concept of a flamethrower tank and were replaced by flamethrower-equipped M4 Shermans in 1945.

In Europe, the M3 formed a large part of the American tank battalions, though following the British path by sidelining the Stuarts from combat duties after heavy losses and to serve alongside Shermans as scouting units. A typical tank battalion for the US Army consisted of three companies of Shermans and one of Stuarts. Other than scouting, the M3s were also used in cavalry roles and infantry support since their cannon are unable to compete with the German tank designs. Despite their dwindling capabilities in battle, the M3 was kept in service up until the end of the war due to the large production numbers.

After World War II, the Stuarts were given out as cheap surplus, countries such as China, India, and Pakistan picked up a few and used them in their conflicts. Portuguese also picked up a few M3s for the war in Angola, and the South African Corps continued using the Stuarts until 1955, where some were still kept in service until 1968 due to available parts. Today, Paraguay is still a user of the M3 light tanks, though as the only tracked armour used in the country.

The Stuart light tank design was also quite versatile that it was made into different variants for different roles on the battlefield. It served as an infantry support vehicle as to the 75 mm GMC M8 and experiments were also taken to see if it could be adapted to an anti-aircraft gun and a flamethrower as well. However, the M3 was becoming an ageing design with inferior armour, cramped interior layout, and a small 37 mm gun, so a program to replace the light tank began in 1943 and became the M24 Chaffee, which would eventually replace the M3 Light Tank mostly after World War II.

The USMC variant represents an M3A1 used by the United States Marines Corps.


Archive of the in-game description

Production of the M3A1 Stuart modification got underway in April 1942, with its primary changes affecting turret construction. The turret was a horseshoe-shaped M3, though it did not have a cupola, and two triangular hatches on its roof served as exits for the crew. The gunner and reloader had periscopes. The turret rotated using a power traverse as opposed to the manually rotated M3. Its faster rotation speed required changes in its construction, in particular a basket fitted with seats for the crew members.

The M23 mantlet was fitted with a 37 mm M6 cannon featuring a gyro stabilizer that significantly boosted accuracy while on the move. That did, however, require more training for gunners, a difficult assignment under battlefield conditions. The sponson-mounted immobile M1919A4 machine guns were replaced with additional ammunition storage, pushing the tank's capacity to 116 shells and 6,400 bullets.

From April to August of 1942 the M3A1 was produced alongside the M3. Changes were made gradually, meaning that some later M3s featured welded bodies and new turrets. They lacked, however, the basket and power traverse, and were called Stuart Hybrids. Some early M3A1s had sponson-mounted machine guns (the intervening models plugged up the openings) and riveted bodies. By the end of February 1943, 4,621 M3A1s had been assembled, 211 of them with the Guiberson T-1020-4 engines (called Stuart IVs by the British). It is worth noting that the M3A1s with welded bodies should have been designated M3A2s, though that never actually happened.
