The '''Cruiser Tank Grant I''' is a gift Rank II American medium tank with a battle rating of 2.7. It was introduced in [[Update 1.45 "Steel Generals"]] in the initial batch of US vehicles available at launch. It is a modified version of the [[Medium Tank M3 Lee|M3 Lee]] in the American medium tree line with a redesigned turret made for the British Army. It is currently not available for purchase.
 +
 
 +
The Grant 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 (if you are inside it) carriers the main 75mm gun; note that with 2 crew, it is the operational gun. The 37mm gun is in a turret, mounted with a leftward offset. Its main notable difference from the M3 Lee is a redesigned turret.
 +
 
 +
Due to the presence of two cannons, this tank is an excellent multi-role vehicle. You can play it as a brawler combining the agile 37mm gun with the high damage of the 75mm gun, but don't get too close, in fact the turreted gun has a bad depression and, combined with the high profile, tends to make close tanks difficult to hit. You can also play it as a tank destroyer using it from the second line. Note that you can assign a key to use only one of the two guns, with this method you can select as primary weapon the 75mm gun, allowing you to aim directly from it (and not from the point of view of the 37mm gun) and use the bullet drop indicator in [[AB|arcade battles]].

The multiple cannons allow for different combinations of attack. The 75mm gun possesses armour penetration on about the level of the 37mm gun; however, the damage upon penetration is extremely high provided that you use the M61 APCBC shell with HE filler. On the other hand, the 37mm gun allows for close quarters and longer-range fighting, where its high-velocity and effective shell make for good long range targeting while it is also the only cannon on the Grant that has a full 360 degree traverse.
 +
 
 +
Different guns mean different styles of play. You can also play it as a tank destroyer, using its sponson gun to take shots at medium range and its 37mm to cover your flanks and make longer range snipe shots. You can also use it as an assault tank, quickly advancing on points while switching between the powerful 75mm gun and the faster-firing 37mm. In all game modes, you should assign the three gun profiles to different keys, this will allow you to aim using the sights of the three guns separately, allowing you to actually hit things at range with the 75mm gun. 
 +
 
 +
Being at BR 2.7, you have a possibility of facing long-barrelled [[Pz.Kpfw. III]], and [[Pz.Kpfw. IV]], as well as [[T-34]]s, and (rarely) the [[Chi-Nu II]]. The ZiS-30 is also very deadly, as its gun is competitive even at 5.7. Your 75mm gun can reliable penetrate all of these tanks at short range (save the T-34), whereas your 37mm will require some particular shot placement.

'''Pros:'''
 
'''Pros:'''
*
+
* Ability to use two guns: a 37mm and a 75mm - which is very powerful at this rank.
 
+
* Fine frontal armour.
 +
* Side mounted 75mm 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 it's height.
 
'''Cons:'''
 
'''Cons:'''
*
+
* Tall profile, big target.
 +
* Side mounted gun - as much it is advantage, it is disadvantage too.
 +
* Slow traverse speeds make it easy for a light or a particularly speedy medium tank to sneak around the sides.

===Development===
 +
After the development of the [[Medium Tank M2|M2 medium tank]], the Battle of France showed that such a tank was not going to be capable to go against the German [[Pz.Kpfw. III Ausf. F|Panzer IIIs]] and [[Pz.Kpfw. IV Ausf. F1|Panzer IVs]]. 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.
 +
 
 +
The [[Medium Tank M3 Lee|'''M3 Lee''']] tank started from the basis of the M2 Medium Tank, using the chassis and the VVSS suspension system. It was to mount the 75 mm cannon, however it was discovered that the United States does not have a turret design that can mount the 75 mm gun. So as development on the turret proceeded, the 75 mm on the M3 Lee would be a sponson mounted. This design was tested on the M2 medium tank as the ''T5E2'', which was approved for the M3 Lee design. The M3 Lee featured a medium tank with two guns, 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 use of two gun mounts on a tank was similar to the German [[Neubaufahrzeug]] and Soviet [[T-35]] tanks. The M3 Lee's 75 mm gun however presented a huge advantage over contemporary tank armaments, the 75 mm could fire high-explosive rounds for against infantry, yet could fire a shell with a high enough velocity for anti-tank purposes.
 +
 
 +
The M3 Lee's faults was the high profile and the sponson mount for its armament. The M3 Lee was 10 ft. 3 in. tall, a feet 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 Lee 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.Kpfw. IV Ausf. E|Panzer IV]]s.
 +
 
 +
The initial batch of M3 Lees were given to the British for their campaign at North Africa. The British experience with the M3 Lee pointed out most of the M3 Lee's flaws, but they were concerned with the lack of radio in the turret and a lacking in armour, with which they modified the M3 Lee to accommodate. 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 Lee 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 started on the M3 Lee, 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 Lee were the Australians and Indians in the Pacific Theater. The M3 Lee arriving in British arsenal caused confusion as the same "M3" designation was given to the [[Light Tank M3 Stuart|M3 Light Tank]]. This set off the tradition of naming American tanks after generals, where the M3 medium tank earned the [[Medium Tank M3 Lee|''Lee'']] for the Americans ('''Grant''' for the British variant) and the M3 light tank 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. 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 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 [[Medium Tank M4 Sherman|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 [[Pz.Kpfw. V Ausf. D|Panther]], [[Pz.Kpfw._VI_Tiger_Ausf._H1|Tiger I]], or improvement of of old chassis like [[Pz.Kpfw. IV Ausf. G|Panzer IV Ausf. G]] and [[Sturmgeschütz III Ausf. 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 WW2 in some modifications such as tractor and recovery vehicle. The chassis and running gear were adapted by the Canadians to develop their [[M4A5 Ram II|''Ram'' medium tank]].

Description

GarageImage GrantI.jpg

The Cruiser Tank Grant I is a gift Rank II American medium tank with a battle rating of 2.7. It was introduced in Update 1.45 "Steel Generals" in the initial batch of US vehicles available at launch. It is a modified version of the M3 Lee in the American medium tree line with a redesigned turret made for the British Army. It is currently not available for purchase.

The Grant 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 (if you are inside it) carriers the main 75mm gun; note that with 2 crew, it is the operational gun. The 37mm gun is in a turret, mounted with a leftward offset. Its main notable difference from the M3 Lee is a redesigned turret.

Due to the presence of two cannons, this tank is an excellent multi-role vehicle. You can play it as a brawler combining the agile 37mm gun with the high damage of the 75mm gun, but don't get too close, in fact the turreted gun has a bad depression and, combined with the high profile, tends to make close tanks difficult to hit. You can also play it as a tank destroyer using it from the second line. Note that you can assign a key to use only one of the two guns, with this method you can select as primary weapon the 75mm gun, allowing you to aim directly from it (and not from the point of view of the 37mm gun) and use the bullet drop indicator in arcade battles.

Usage in the battles

The multiple cannons allow for different combinations of attack. The 75mm gun possesses armour penetration on about the level of the 37mm gun; however, the damage upon penetration is extremely high provided that you use the M61 APCBC shell with HE filler. On the other hand, the 37mm gun allows for close quarters and longer-range fighting, where its high-velocity and effective shell make for good long range targeting while it is also the only cannon on the Grant that has a full 360 degree traverse.

Different guns mean different styles of play. You can also play it as a tank destroyer, using its sponson gun to take shots at medium range and its 37mm to cover your flanks and make longer range snipe shots. You can also use it as an assault tank, quickly advancing on points while switching between the powerful 75mm gun and the faster-firing 37mm. In all game modes, you should assign the three gun profiles to different keys, this will allow you to aim using the sights of the three guns separately, allowing you to actually hit things at range with the 75mm gun.

Being at BR 2.7, you have a possibility of facing long-barrelled Pz.Kpfw. III, and Pz.Kpfw. IV, as well as T-34s, and (rarely) the Chi-Nu II. The ZiS-30 is also very deadly, as its gun is competitive even at 5.7. Your 75mm gun can reliable penetrate all of these tanks at short range (save the T-34), whereas your 37mm will require some particular shot placement.

Pros and cons

Pros:

  • Ability to use two guns: a 37mm and a 75mm - which is very powerful at this rank.
  • Fine frontal armour.
  • Side mounted 75mm 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 it's height.

Cons:

  • Tall profile, big target.
  • Side mounted gun - as much it is advantage, it is disadvantage too.
  • Slow traverse speeds make it easy for a light or a particularly speedy medium tank to sneak around the sides.

History

Development

After the development of the M2 medium tank, 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. 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.

The M3 Lee tank started from the basis of the M2 Medium Tank, using the chassis and the VVSS suspension system. It was to mount the 75 mm cannon, however it was discovered that the United States does not have a turret design that can mount the 75 mm gun. So as development on the turret proceeded, the 75 mm on the M3 Lee would be a sponson mounted. This design was tested on the M2 medium tank as the T5E2, which was approved for the M3 Lee design. The M3 Lee featured a medium tank with two guns, 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 use of two gun mounts on a tank was similar to the German Neubaufahrzeug and Soviet T-35 tanks. The M3 Lee's 75 mm gun however presented a huge advantage over contemporary tank armaments, the 75 mm could fire high-explosive rounds for against infantry, yet could fire a shell with a high enough velocity for anti-tank purposes.

The M3 Lee's faults was the high profile and the sponson mount for its armament. The M3 Lee was 10 ft. 3 in. tall, a feet 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 Lee 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.

The initial batch of M3 Lees were given to the British for their campaign at North Africa. The British experience with the M3 Lee pointed out most of the M3 Lee's flaws, but they were concerned with the lack of radio in the turret and a lacking in armour, with which they modified the M3 Lee to accommodate. 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 Lee 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 started on the M3 Lee, 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 Lee were the Australians and Indians in the Pacific Theater. The M3 Lee arriving in British arsenal caused confusion as the same "M3" designation was given to the M3 Light Tank. This set off the tradition of naming American tanks after generals, where the M3 medium tank earned the Lee for the Americans (Grant for the British variant) and the M3 light tank 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. 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.

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 WW2 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.

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[1]
