The '''{{specs|name}}''' is a gift Rank {{specs|rank}} Russian medium tank {{Battle-rating|1}}. It was introduced sometime during [[Update_1.55_"Royal_Armour"|Update 1.55 "Royal Armour"]]. It was first obtained via the special event "Defender combined battles" in 20 February 2016 and has been occasionally available to be obtained since. It is virtually identical to the M3 Lee; the different name comes from the Russian designation of just "M3 Medium".
 +
 
 +
The M3 Lee is most well recognized for its tall profile and two cannons. The suspension resembles that of the [[M4|M4 Sherman]], the only notable difference being the return rollers' positions. The hull front is also stepped into two plates, where the upper is closer to vertical. The large sponson on the right side of the tank carries the main 75 mm gun; note that with 2 crew, it is the operational gun. The 37 mm gun is in a turret, mounted with a leftward offset, and has a small MG cupola on top.

When combating this tank, avoid its 75 mm gun by flanking the vehicle, then get in close and hug the sides or rear of the vehicle to prevent them form turning and going under the 37 mm's depression range. Aim for the large superstructure, a solid penetration will knock out all 6 crew members or make the ammunition combust. Note that firing through the side hatch will usually destroy the tank in one-shot, owing to the lack of sloping and ammunition storage.

The multiple cannons allow for different combinations of attack. The 37 mm gun on the full 360° traverse turret allows for a diverse role on the M3, with its high-velocity and effective round for long-range fighting, but with a fast reload for close-quarter encounters. The 75 mm on the sponson mount has the same penetration level as the 37 mm, but with a very high post-penetration damage with the right ammo at the cost of lower velocity, and thus a shorter battle range. The limited traverse on the 75 mm mount also means it is not as flexible as the turreted 37 mm. With these two cannon, the M3 Lee can focus on a close-range combat with the two cannons fighting a single tank, or engage two separate tanks at a longer range. Closer range combat is supported by the M3's adequate sloped frontal armour, able to withstand most enemy fire at its battle rating. It is recommended to set the keys to allow separate firing of the cannons for maximum effectiveness.
 +
 
 +
Still, the different guns mean different styles of play. The M3 can also play as a tank destroyer, using its sponson gun to take shots at medium range and its 37 mm to cover the flanks and make longer range snipe shots. The M3 Lee can also be used as an assault tank, quickly advancing on points while switching between the powerful 75 mm gun and the faster-firing 37 mm. It is also possible to completely ignore the 37 mm and focus solely on the 75 mm as it is a far more effective gun with its HE filler in its APCBC, as well as being easier to manage for newer players. In all game modes, the weapons should be assigned to different keys, this will allow the tank to aim using the sights of the three guns separately, allowing more accurate targeting at ranges, especially for the 75 mm gun. Since the 75 mm is in a side sponson, it is also possible to approach cover to where only the 37 mm is showing, allowing the tank to fire with most of the tank's profile hidden.

'''Pros:'''
 
'''Pros:'''
*
+
* Ability to use two guns: a 37mm and a 75mm - which is unique as well as useful at this rank.
 
+
* Best gun depression of all Russian tanks at this battle rating: -7°
 +
* Acceptable frontal armour
 +
* Side mounted 75 mm gives the ability for some unique tactics
 +
* Despite the tall profile, the "wedding cake" design of the turret has thick sloped armour, providing extra protection to make up for its height.
 +
* 6 crew members, harder to fully incapacitate
 +
* Good for researching low rank tanks.
 +
* Premium and Research rewards.
 
'''Cons:'''
 
'''Cons:'''
*
+
* Tall profile, big target
 +
* 75 mm sponson weapon does not allow for hull-down combat
 +
* Tall position of turret restricts gun depression
 +
* Slow traverse speeds make it easy for a light or a particularly speedy medium tank to sneak around the sides
 +
* Weak side armour
 +
* Very awkward to use for new players.

===Development===
 +
The current main tank in US inventory in 1940 was the [[M2|M2 medium tank]], but the Battle of France showed that such a tank was not going to be capable to go against the German [[Pz.III F|Panzer IIIs]] and [[Pz.IV F1|Panzer IVs]] and their Panzer Divisions. With the Western Allies now embroiled in the North African campaign against the Germans and Italians, the Allies needed a good tank capable of going against the Panzer tanks, and they needed it quickly.<ref name="ZalogaM3Med">Zaloga Steven. ''M3 Lee/Grant Medium Tank 1941-45'' Great Britain: Osprey Publishing Ltd., 2005</ref>
 +
 
 +
The new tank design took elements from the M2 Medium, using the chassis and its VVSS suspension system. Part of the requirement for the new tank was to mount the more powerful 75 mm cannon. However it was discovered that the United States does not have a turret design that can mount the 75 mm gun. But turret development takes time, and a new tank capable of fighting the Germans was needed now. Taking elements from French designs such as the Char B1, with its two cannon mounts, the American designers decided that the 75 mm, if can't be mounted on a turret, should be mounted on a sponson design on the hull. This design was tested on the M2 medium tank as the ''T5E2''. Ordnance approved it as combat-capable and the design was approved as the '''M3 Medium'''. The M3 Medium design had two cannons, the 75 mm on the hull sponson mount, and a 37 mm with a coaxial machine gun on a turret, a cupola on the turret had its own machine gun. The M3 Lee's 75 mm gun however presented a huge advantage over contemporary tank armaments as the 75 mm could fire high-explosive rounds for fortifications and artillery pieces, yet could fire a shell with a high enough velocity for anti-tank purposes.
 +

The M3 design's faults was the high profile and the sponson mount for its armament. The M3 was 10 ft. 3 in. tall, a foot taller than the M2 medium tank. The 75 mm on a sponson mount meant that the main armament of the tank had a limited traverse compared to a rotatable turret and forced the tank to reveal much of its body in order to aim the gun at the enemy. The M3 Medium was also constructed out of rivets (which increased spalling) and had a smooth track design which reduced ground traction. Despite these disadvantages, the Allies happily accepted them as they were critically low on tanks, and German Colonel Hans von Luck considered them superior to the [[Pz.IV E|Panzer IV]]s from his experience in Africa.

The initial batch of M3 Lees were given to the British for their campaign at North Africa. The British experience with the M3 design pointed out most ofits flaws, but they were concerned with the lack of radio in the turret and a lacking in armour, with which they requested a redesign. The new design had a new cast turret with room for a radio, the hull had thicker armour, and the turret cupola's machine gun was removed for a simple hatch. The modified M3 also required one less crew member due to the radio now being in the turret for the commander rather than for a radio operator. The British ordered 1,250 of these modified M3 medium tanks.

 +
On August 1941, production officially started on the M3 Mediums, though the armour was thicker than initials batches of the tank due to its combat experiences. A majority of these were completed at Baldwin Locomotive Works in Philadelphia, Pennsylvania. Of the total 6,258 M3s built between start up to the end of production in December 1942, 2,855 units went to the British and 1,386 went to the Soviet Union. Other users of the M3 were the Australians and Indians in the Pacific Theater. The M3 Mediums arriving in British arsenal caused confusion as the same "M3" designation was given to the [[M3 Stuart|M3 Light Tank]], plus there were two different design types of the M3 Mediums. This set off the tradition of naming American tanks after generals, where the M3 medium tank earned the ''Lee'' for the initial Americans design, [[Grant I|''Grant'']] for the British redesign, and the M3 light tank and its [[M5A1|successors]] earned the ''Stuart''.

===Combat usage===
 +
Combat experience with the M3 Lee was complicated, but favorable. In Africa, the Lees and Grants in British and American service surprised the German forces when they could withstand the [[KwK 38 (50 mm)|50 mm KwK 38 L/42 gun]] and [[KwK 37 (75 mm)|75 mm KwK 37 L/24 howitzer]] armament on the Panzer IIIs and Panzer IVs. The M3 Lee proved reliable and adequate in armour protection in British and American service. The Soviet's experience with the M3 Lee was less favorable, as their [[T-34 (1941)|T-34 tanks]] were much better in combat performance. The Soviets euphemistically called it a "grave for six men" and the Lee tanks were relegated to the secondary fronts or repurposed as armoured personnel carriers. In the Pacific, the M3 Lees were lent to the Australians and Indians, which proved vastly superior to the Japanese tanks in service. The high gun elevation on its 37 mm turret and machine guns proved effective in knocking Japanese sniper off from trees. The only American use of the M3 Lee at the Pacific Theater was during the Battle of Makin Island.

 +
The M3 Lee served fine as a stop gap solution for the American tank development. They performed very well on the combat field and proved very reliable. However, once a 75 mm turret was finally designed, the M3 Lee was redesigned to use it, and the resulting tank was the [[M4|M4 Sherman]], which will go on to replace the M3 tanks in the Allies as they are withdrawn from service. Even if it wasn't, the M3 was becoming obsolete due to newer German tanks being deployed, such as the [[Panther D|Panther]], [[Tiger_H1|Tiger I]], or improvement of of old chassis like [[Pz.IV G|Panzer IV Ausf. G]] and [[StuG III F|StuG III Ausf. F]]. Its obsolescence was a consequence of its own rather unique development and anachronistic design, limiting this medium tank's service life to a mere two years in Allied hands. However it lived on until the end of World War II in some modifications such as tractor and recovery vehicle. The chassis and running gear were adapted by the Canadians to develop their [[M4A5|''Ram'' medium tank]].<ref name="ZalogaM3Med"/>

Description

GarageImage M3 Medium (USSR).jpg

The ▂M3 Medium is a gift Rank I Russian medium tank with a battle rating of 2.7 (AB/RB/SB). It was introduced sometime during Update 1.55 "Royal Armour". It was first obtained via the special event "Defender combined battles" in 20 February 2016 and has been occasionally available to be obtained since. It is virtually identical to the M3 Lee; the different name comes from the Russian designation of just "M3 Medium".

The M3 Lee is most well recognized for its tall profile and two cannons. The suspension resembles that of the M4 Sherman, the only notable difference being the return rollers' positions. The hull front is also stepped into two plates, where the upper is closer to vertical. The large sponson on the right side of the tank carries the main 75 mm gun; note that with 2 crew, it is the operational gun. The 37 mm gun is in a turret, mounted with a leftward offset, and has a small MG cupola on top.

  • Hull doors and vision ports are 38.1 mm thick.

When combating this tank, avoid its 75 mm gun by flanking the vehicle, then get in close and hug the sides or rear of the vehicle to prevent them form turning and going under the 37 mm's depression range. Aim for the large superstructure, a solid penetration will knock out all 6 crew members or make the ammunition combust. Note that firing through the side hatch will usually destroy the tank in one-shot, owing to the lack of sloping and ammunition storage.

Usage in the battles

The multiple cannons allow for different combinations of attack. The 37 mm gun on the full 360° traverse turret allows for a diverse role on the M3, with its high-velocity and effective round for long-range fighting, but with a fast reload for close-quarter encounters. The 75 mm on the sponson mount has the same penetration level as the 37 mm, but with a very high post-penetration damage with the right ammo at the cost of lower velocity, and thus a shorter battle range. The limited traverse on the 75 mm mount also means it is not as flexible as the turreted 37 mm. With these two cannon, the M3 Lee can focus on a close-range combat with the two cannons fighting a single tank, or engage two separate tanks at a longer range. Closer range combat is supported by the M3's adequate sloped frontal armour, able to withstand most enemy fire at its battle rating. It is recommended to set the keys to allow separate firing of the cannons for maximum effectiveness.

Still, the different guns mean different styles of play. The M3 can also play as a tank destroyer, using its sponson gun to take shots at medium range and its 37 mm to cover the flanks and make longer range snipe shots. The M3 Lee can also be used as an assault tank, quickly advancing on points while switching between the powerful 75 mm gun and the faster-firing 37 mm. It is also possible to completely ignore the 37 mm and focus solely on the 75 mm as it is a far more effective gun with its HE filler in its APCBC, as well as being easier to manage for newer players. In all game modes, the weapons should be assigned to different keys, this will allow the tank to aim using the sights of the three guns separately, allowing more accurate targeting at ranges, especially for the 75 mm gun. Since the 75 mm is in a side sponson, it is also possible to approach cover to where only the 37 mm is showing, allowing the tank to fire with most of the tank's profile hidden.

Pros and cons

Pros:

  • Ability to use two guns: a 37mm and a 75mm - which is unique as well as useful at this rank.
  • Best gun depression of all Russian tanks at this battle rating: -7°
  • Acceptable frontal armour
  • Side mounted 75 mm gives the ability for some unique tactics
  • Despite the tall profile, the "wedding cake" design of the turret has thick sloped armour, providing extra protection to make up for its height.
  • 6 crew members, harder to fully incapacitate
  • Good for researching low rank tanks.
  • Premium and Research rewards.

Cons:

  • Tall profile, big target
  • 75 mm sponson weapon does not allow for hull-down combat
  • Tall position of turret restricts gun depression
  • Slow traverse speeds make it easy for a light or a particularly speedy medium tank to sneak around the sides
  • Weak side armour
  • Very awkward to use for new players.

History

Development

The current main tank in US inventory in 1940 was the M2 medium tank, but the Battle of France showed that such a tank was not going to be capable to go against the German Panzer IIIs and Panzer IVs and their Panzer Divisions. With the Western Allies now embroiled in the North African campaign against the Germans and Italians, the Allies needed a good tank capable of going against the Panzer tanks, and they needed it quickly.[1]

The new tank design took elements from the M2 Medium, using the chassis and its VVSS suspension system. Part of the requirement for the new tank was to mount the more powerful 75 mm cannon. However it was discovered that the United States does not have a turret design that can mount the 75 mm gun. But turret development takes time, and a new tank capable of fighting the Germans was needed now. Taking elements from French designs such as the Char B1, with its two cannon mounts, the American designers decided that the 75 mm, if can't be mounted on a turret, should be mounted on a sponson design on the hull. This design was tested on the M2 medium tank as the T5E2. Ordnance approved it as combat-capable and the design was approved as the M3 Medium. The M3 Medium design had two cannons, the 75 mm on the hull sponson mount, and a 37 mm with a coaxial machine gun on a turret, a cupola on the turret had its own machine gun. The M3 Lee's 75 mm gun however presented a huge advantage over contemporary tank armaments as the 75 mm could fire high-explosive rounds for fortifications and artillery pieces, yet could fire a shell with a high enough velocity for anti-tank purposes.

The M3 design's faults was the high profile and the sponson mount for its armament. The M3 was 10 ft. 3 in. tall, a foot taller than the M2 medium tank. The 75 mm on a sponson mount meant that the main armament of the tank had a limited traverse compared to a rotatable turret and forced the tank to reveal much of its body in order to aim the gun at the enemy. The M3 Medium was also constructed out of rivets (which increased spalling) and had a smooth track design which reduced ground traction. Despite these disadvantages, the Allies happily accepted them as they were critically low on tanks, and German Colonel Hans von Luck considered them superior to the Panzer IVs from his experience in Africa.

The initial batch of M3 Lees were given to the British for their campaign at North Africa. The British experience with the M3 design pointed out most ofits flaws, but they were concerned with the lack of radio in the turret and a lacking in armour, with which they requested a redesign. The new design had a new cast turret with room for a radio, the hull had thicker armour, and the turret cupola's machine gun was removed for a simple hatch. The modified M3 also required one less crew member due to the radio now being in the turret for the commander rather than for a radio operator. The British ordered 1,250 of these modified M3 medium tanks.

On August 1941, production officially started on the M3 Mediums, though the armour was thicker than initials batches of the tank due to its combat experiences. A majority of these were completed at Baldwin Locomotive Works in Philadelphia, Pennsylvania. Of the total 6,258 M3s built between start up to the end of production in December 1942, 2,855 units went to the British and 1,386 went to the Soviet Union. Other users of the M3 were the Australians and Indians in the Pacific Theater. The M3 Mediums arriving in British arsenal caused confusion as the same "M3" designation was given to the M3 Light Tank, plus there were two different design types of the M3 Mediums. This set off the tradition of naming American tanks after generals, where the M3 medium tank earned the Lee for the initial Americans design, Grant for the British redesign, and the M3 light tank and its successors earned the Stuart.

Combat usage

Combat experience with the M3 Lee was complicated, but favorable. In Africa, the Lees and Grants in British and American service surprised the German forces when they could withstand the 50 mm KwK 38 L/42 gun and 75 mm KwK 37 L/24 howitzer armament on the Panzer IIIs and Panzer IVs. The M3 Lee proved reliable and adequate in armour protection in British and American service. The Soviet's experience with the M3 Lee was less favorable, as their T-34 tanks were much better in combat performance. The Soviets euphemistically called it a "grave for six men" and the Lee tanks were relegated to the secondary fronts or repurposed as armoured personnel carriers. In the Pacific, the M3 Lees were lent to the Australians and Indians, which proved vastly superior to the Japanese tanks in service. The high gun elevation on its 37 mm turret and machine guns proved effective in knocking Japanese sniper off from trees. The only American use of the M3 Lee at the Pacific Theater was during the Battle of Makin Island.

The M3 Lee served fine as a stop gap solution for the American tank development. They performed very well on the combat field and proved very reliable. However, once a 75 mm turret was finally designed, the M3 Lee was redesigned to use it, and the resulting tank was the M4 Sherman, which will go on to replace the M3 tanks in the Allies as they are withdrawn from service. Even if it wasn't, the M3 was becoming obsolete due to newer German tanks being deployed, such as the Panther, Tiger I, or improvement of of old chassis like Panzer IV Ausf. G and StuG III Ausf. F. Its obsolescence was a consequence of its own rather unique development and anachronistic design, limiting this medium tank's service life to a mere two years in Allied hands. However it lived on until the end of World War II in some modifications such as tractor and recovery vehicle. The chassis and running gear were adapted by the Canadians to develop their Ram medium tank.[1]

An anecdote

"The 75 (mm gun) is firing. The 37 (mm gun) is firing, but it is traversed round the wrong way. The Browning (machine gun) is jammed. I am saying ‘Driver advance’ on the A set and the driver, who can’t hear me, is reversing. And as I look over the top of the turret and see twelve enemy tanks fifty yards away, someone hands me a cheese sandwich.” —British Lieutenant Ken Giles, tank commander of a M3 Grant[2]
