{{break}}
The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.79 "Project X"]].

The XM-1 (GM) feels like a [[M1 Abrams]], being a prototype of that very vehicle. However, its specifications encourage anything but an M1 Abrams playstyle. You want to play the XM-1 (GM) like you would play a [[Leopard A1A1|Leopard]] or a [[Ru 251]]. Use your speed, mobility, and gun to hit the weak-spots on enemy tanks armour.

One thing to note with the XM-1 (GM) is its extremely loud tracks, in some cases louder than the engine. This can be annoying, to say the least.

Unless it has all skins unlocked, it is either going to be OD Green or on desert maps a sandy yellow/brown colour. Other distinctive features on the vehicle are the combined Gunner/Commander sight is also a distinctive feature as well as the angled hull very reminiscent of the Leopards in-game. The vehicle also employs a [[hydropneumatic suspension]]. This vehicle comes with night vision for the commander and driver, and thermal sights for the gunner.

== Usage in battles ==


This vehicle is best used as a support tank and not as a "brawler". Flanking is where this tank succeeds, using its speed and manoeuvrability to get to the rear or sides of the enemy. Another good tactic is to shoot-and-scoot to maximize the manoeuvrability and gun over an opponent.

Some enemies to be concerned about:

*T-64B(V): Aim for the drivers hatch if you facing it frontally. If possible, get around its side and hit it dead under the turret, you will blow up its ammo racks this way.
*Leopard 2K: The Leo 2K is extremely potent against XM-1's seeing as their speed and mobility is similar but the Leo has a better gun. The 2K, however, lacks sufficient armour to defeat your ammunition so hit the lower front plate or turret with M735.
*Leopard 2A4/Type 90: The hull and gun mantlets are weak spots and can be penetrated with M735. The Type 90 also has a glaring turret ring that can easily be targeted and penetrated.

=== Pros and cons ===

'''Pros:'''

* Very good speed, manoeuvrability and acceleration
* Very fast turret traverse
* Excellent manoeuvrability/speed
* Has hydropneumatic suspension control
* Not one, not two, but three secondary machine guns
* Blow out ammo rack prevents an ammo shot from destroying the tank immediately
* Driver and commander get IR vision systems, while gunner has a thermal NVD

'''Cons:'''

* Average gun against enemies
* While it has composite armour, it is useless against most weapons it will face
* Gun is sub-par; same APFSDS round (360 mm of penetration point-blank) as on the Type 74 and M60A1 (AOS)
* Front plate is made up of spaced armour, which doesn't provide the protection comparable to composite
* Similar ammo storage to the M1 Abrams, has the same side weak spot (although it is rarely exploited, due to the sub-par armour everywhere else)
* Tracks are very noisy (louder than the engine!)

== History ==


It started in the early 1970s, at the height of the Cold War and the arms race. After the joint German-American project to create the MBT-70 main battle tank was closed, and the new all-American XM803 project was deemed an insufficient and too expensive response to the newest Soviet developments, the US Department of Defense developed a new list of requirements for the future American main battle tank. Two engineering giants joined the contest: the Chrysler and General Motors companies. Both contestants decided to use the developments for the MBT-70 and XM803 to design a new tank. Many corrections and additions were made to the tactical and technical requirements of the American government, first and foremost, on the defensive characteristics of the future main battle tank. The requirements for the tank’s armour and survivability increased, along with its maintainability in the field. In addition, the Arab-Israeli conflict showed that a modern tank must have the ability to effectively destroy armoured targets at long distances, including with kinetic shells, and also have a sufficiently large complement of shells. In spite of the changes and additions to the technical specification, the contestants managed to achieve their goals, and by 1976, they presented their developments, the experimental prototypes of the XM-1 tank, for testing. Both vehicles were outwardly very similar, with practically identical dimensions. They were alike in their layouts and used the same 105 mm M68 rifled cannon. Both tanks turned out very well. Which prototype did the military choose, and why?

The XM-1 (GM), the contest model from General Motors, became a further development of ideas and technological solutions for the MBT-70 and XM803 projects, including the diesel powertrain and mixed undercarriage with six roller wheels per side, three with hydraulic suspension and three with torsion bar suspension. The competitor to General Motors, the Chrysler company, used their XM-1 (C) model to present not only a progressive gas-turbine engine but also a new undercarriage with seven independent roller wheels on each side with individual torsion bar suspension. In addition, the Chrysler engineers were able to save funds on constructing the tank by optimizing the components of the aiming equipment and the gun stabilization system. These details played a decisive role in the selection of the contractor to make the XM-1 project a reality. In spite of the fact that numerous flaws and “teething problems” arose during the project, the prototype for the USA’s next-generation main battle tank was confirmed. After several cycles of correcting issues and modernizing the prototype XM-1 (C), the first vehicles began to be deployed under the designation M1 Abrams.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.81 "The Valkyries"]].

At first glance this tank looks very similar to the M48 and M103, since it's built on an M48 hull, but with a rather different turret. The reason for this is because it is an oscillating turret, like the ones found on contemporary french tanks like the AMX-50. The main feature which sets this tank apart from other Rank V American tanks is the automatic loader. This tank features a drum-type automatic loader, similar to the ones found on french tanks like the AMX-50 and Lorraine 40t.

Thus, the T54E1 inherits the hull armour of the M48, but combines it with a powerful 105 mm gun, and an automatic loader.

== Usage in battles ==

Since this tank is based on the hull of the M48, it inherits that tank's mediocre armour and top speed. But unlike the M48, this tank features a powerful 105 mm gun, meaning you'll have no problem penetrating the armour of enemy tanks. Unlike tanks with the 105 mm L7/M68 gun, this tank also has a powerful APBC round, which can be used to destroy opponents with weaker armour, like the Leopard I, or when shooting tanks from the side. This round, when it penetrates, is much more damaging than the HEAT-FS round because it creates much more spalling. For opponents with armour the APBC round can't pen, like the frontal armour on most Russian tanks, the HEAT-FS round is the most effective. Thanks to its very fast automatic loader this reloads almost twice as fast as most manually loaded tanks, meaning you'll be able to dish out serious damage in a very short time. It also means you're much better at recovering from a missed shot, since you'll be able to shoot again in just five seconds. You will have to make sure you won't empty the drum magazine of the automatic loader, since it takes more than 20 seconds to reload a single round from one of the other ammunition racks into the autoloader.

Knowing this, this tank is best played in a support role, destroying tanks for your teammates, but not actively participating in close-range brawls with enemy tanks. It can be used in a flanking role, but due to its mediocre top speed it's vulnerable to being flanked itself and isn't capable of reaching good ambush positions before the enemy does.

=== Pros and cons ===


'''Pros:'''
* Very fast reload, thanks to its auto-loader this tank has a 5.0 second reload
* High-penetrating HEAT-FS plus a hard-hitting solid shot round
* Good acceleration
* The APDS round is slightly better than the ones found on the M60 and other 105 mm L7/M68 armed tanks
* Like most other American tanks, this tank is fitted with a 50 cal machine gun, which is effective against lightly armoured vehicles and planes

'''Cons:'''
* Once the first-stage ammunition stowage has been depleted, the reload time increases drastically. This can be avoided by reloading at a capture point, since rounds replenished on a capture point automatically go into the first stage ammunition rack
* Mediocre top speed, most contemporary tanks outpace it
* The armour doesn't really protect against HEAT-FS and APDS, both of which it'll commonly face
* No stabilizer, making aiming while on the move difficult

== History ==

No sooner than the M48 Patton began being issued to armored units, American engineers already started working on potential improvements to its design. In particular, engineers focused on upgrading the vehicle's firepower. This in turn, lead to the creation of the T54, a new vehicle based on the M48’s chassis.

Initially, two versions of prototypes were planned, but a lighter and cheaper third one was proposed in 1952. All three versions of the T54 were armed with a modified version of the T5 105 mm gun, but featured different turrets and gun loading methods. The T54E1 was the second prototype, equipped with an oscillating turret similar to the ones found on contemporary French tanks, and a drum-fed autoloading mechanism with a capacity of 9 rounds.

By 1957, all three prototype versions had undergone comprehensive testing at Fort Knox and the Aberdeen proving grounds. However, as the interest of the Army shifted towards the more promising T95 project, the decision was made to cancel the T54 project in 1957. A total of less than a dozen T54s were constructed, of which two were T54E1s.

{{break}}
The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.79 "Project X"]].

The XM-1 (GM) feels like a [[M1 Abrams]], being a prototype of that very vehicle. However, its specifications encourage anything but an M1 Abrams playstyle. You want to play the XM-1 (GM) like you would play a [[Leopard A1A1|Leopard]] or a [[Ru 251]]. Use your speed, mobility, and gun to hit the weak-spots on enemy tanks armour.

One thing to note with the XM-1 (GM) is its extremely loud tracks, in some cases louder than the engine. This can be annoying, to say the least.

Unless it has all skins unlocked, it is either going to be OD Green or on desert maps a sandy yellow/brown colour. Other distinctive features on the vehicle are the combined Gunner/Commander sight is also a distinctive feature as well as the angled hull very reminiscent of the Leopards in-game. The vehicle also employs a [[hydropneumatic suspension]]. This vehicle comes with night vision for the commander and driver, and thermal sights for the gunner.

== General info ==
=== Survivability and armour ===
''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?''

''If necessary use a visual template to indicate the most secure and weak zones of the armour.''

== Usage in battles ==


This vehicle is best used as a support tank and not as a "brawler". Flanking is where this tank succeeds, using its speed and manoeuvrability to get to the rear or sides of the enemy. Another good tactic is to shoot-and-scoot to maximize the manoeuvrability and gun over an opponent.

Some enemies to be concerned about:

*T-64B(V): Aim for the drivers hatch if you facing it frontally. If possible, get around its side and hit it dead under the turret, you will blow up its ammo racks this way.
*Leopard 2K: The Leo 2K is extremely potent against XM-1's seeing as their speed and mobility is similar but the Leo has a better gun. The 2K, however, lacks sufficient armour to defeat your ammunition so hit the lower front plate or turret with M735.
*Leopard 2A4/Type 90: The hull and gun mantlets are weak spots and can be penetrated with M735. The Type 90 also has a glaring turret ring that can easily be targeted and penetrated.

=== Pros and cons ===

'''Pros:'''

* Very good speed, manoeuvrability and acceleration
* Very fast turret traverse
* Excellent manoeuvrability/speed
* Has hydropneumatic suspension control
* Not one, not two, but three secondary machine guns
* Blow out ammo rack prevents an ammo shot from destroying the tank immediately
* Driver and commander get IR vision systems, while gunner has a thermal NVD

'''Cons:'''

* Average gun against enemies
* While it has composite armour, it is useless against most weapons it will face
* Gun is sub-par; same APFSDS round (360 mm of penetration point-blank) as on the Type 74 and M60A1 (AOS)
* Front plate is made up of spaced armour, which doesn't provide the protection comparable to composite
* Similar ammo storage to the M1 Abrams, has the same side weak spot (although it is rarely exploited, due to the sub-par armour everywhere else)
* Tracks are very noisy (louder than the engine!)

== History ==


It started in the early 1970s, at the height of the Cold War and the arms race. After the joint German-American project to create the MBT-70 main battle tank was closed, and the new all-American XM803 project was deemed an insufficient and too expensive response to the newest Soviet developments, the US Department of Defense developed a new list of requirements for the future American main battle tank. Two engineering giants joined the contest: the Chrysler and General Motors companies. Both contestants decided to use the developments for the MBT-70 and XM803 to design a new tank. Many corrections and additions were made to the tactical and technical requirements of the American government, first and foremost, on the defensive characteristics of the future main battle tank. The requirements for the tank’s armour and survivability increased, along with its maintainability in the field. In addition, the Arab-Israeli conflict showed that a modern tank must have the ability to effectively destroy armoured targets at long distances, including with kinetic shells, and also have a sufficiently large complement of shells. In spite of the changes and additions to the technical specification, the contestants managed to achieve their goals, and by 1976, they presented their developments, the experimental prototypes of the XM-1 tank, for testing. Both vehicles were outwardly very similar, with practically identical dimensions. They were alike in their layouts and used the same 105 mm M68 rifled cannon. Both tanks turned out very well. Which prototype did the military choose, and why?

The XM-1 (GM), the contest model from General Motors, became a further development of ideas and technological solutions for the MBT-70 and XM803 projects, including the diesel powertrain and mixed undercarriage with six roller wheels per side, three with hydraulic suspension and three with torsion bar suspension. The competitor to General Motors, the Chrysler company, used their XM-1 (C) model to present not only a progressive gas-turbine engine but also a new undercarriage with seven independent roller wheels on each side with individual torsion bar suspension. In addition, the Chrysler engineers were able to save funds on constructing the tank by optimizing the components of the aiming equipment and the gun stabilization system. These details played a decisive role in the selection of the contractor to make the XM-1 project a reality. In spite of the fact that numerous flaws and “teething problems” arose during the project, the prototype for the USA’s next-generation main battle tank was confirmed. After several cycles of correcting issues and modernizing the prototype XM-1 (C), the first vehicles began to be deployed under the designation M1 Abrams.

{{Specs-Card|code=us_t20}}

== Description ==

[[File:GarageImage_T20.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.63 "Desert Hunters"]]. Intended as a replacement for the [[M4|M4 Sherman]] tank, it features a rear transmission that gives it a much lower profile than the Sherman series, as well as the [[M1 (76 mm)|76 mm gun]] for additional anti-tank firepower.

The T20 is a more mobile and smaller vehicle platform than the Sherman series. A vehicle with a similar play style to the T20 would be the [[T25|T25]], not surprising considering the T25 is an upgrade of the T20 prototype models.

== General info ==
=== Survivability and armour ===

The armour is similar to a late M4 Sherman model with a sloped 63.5 mm, as such enemies that can take out the M4 (76) models will also be able to penetrate the T20 straight through the front hull unless compound angling.

'''Armour type:'''

'''Notes:'''
* Suspension wheels and tracks are 20 mm thick.
* The sides have boxes and sand skirts that give an additional 4 mm of armour
* Belly armour is 12.7 mm thick.

=== Mobility ===

The T20's greatest strength lays in its mobility. The forward and reverse speed are nearly the same due to the transmission, so retreating from cover after exposing itself to fire is easy and quick.

Armed with the 76 mm M1 gun, the T20's armament can do sterling performances against vehicles of its caliber, so while the T20 itself is easy to take out, it can destroy the enemy the same if it can get the first penetrating shot off first. The front placement of the turret also allows the T20 to expose the minimum amount of its body when it comes out to fire. The 76 mm

== Usage in the battles ==

===Tactics===
'''Offense:''' The T20 in an offensive mode should be done by exploiting its mobility with the terrain. Thus, the T20 would be great in areas with lots of cover. Unless in a close-range engagement or in an emergency, it is not recommended to fire the T20's cannon while on the move just like any other tank as it affects accuracy. Thus, the T20 should move forwards, make contact with an enemy, fire if possible then move to cover if the enemy was not taken out with the first shot. The T20 should not go alone due to the vulnerability of its armour, so make sure allies are accompanied with the T20 for additional firepower and protection, most preferably a heavy tank.

'''Defense:''' The T20 in a defensive mode should be played similarly like the [[M18 GMC|M18 Hellcat]] due to its mobility and firepower. However, a benefit over the M18 is the increased armour, so more risk could be taken with exposing the tank to the enemy to get a good shot placement. Allow the enemy to run their tank into the T20's line of sight, don't try to move and expose the tank otherwise the attacking enemy tank would be aware of the T20's position and also may shoot first, disabling critical components if not destroying the T20 outright. Due to the positioning of the internal components, an enemy tank attacking the rear would actually minimize the damage to the crew compartment as the shell must pass through both the transmission and the engine. If the turret ring and crew remain untouched (unlikely, but a possibility), the player could traverse the turret to the enemy at the rear and attack it, though the attack on the engine may also create a fire, so the ''FPE'' modification is necessary for this unorthodox method.

===Other considerations===
Medium tanks are not a real issue for the 76 mm unless it is the [[Panther D|Panther]], in which case the 76 mm must be aimed at the gun mantlet to do any reliable penetration from the front. The times when any other medium tank can deflect a shot from the gun is if they compound angle their front glacis armour, so try not to waste a shot on say a [[T-34-85 (D-5T)|T-34]] that has angled its front armour 45 degrees toward the T20. It'd be a much better chance if the gun was aimed at the turret.

Heavy tanks such as the [[Tiger H1|Tiger I]] and [[IS-1]] may be more difficult due to their thick armour and their heavy armament means a hit to the T20 is not good. Thus, it is important to catch these tanks off guard via making the heavy tanks concentrate on a different enemy while the T20 moves in for a clean shot, or catch them while reloading.

Any tanks at the BR will, of course, be easy targets if the T20 catch them at their sides, which is very possible due to the greater mobility of the tank. A single hit from the 76 mm APCBC shell will devastate the interior and can lead to quick destruction or loss in combat efficiency.

A lot of enemies at the battle rating can take the T20 out, even the [[M4A1|75 mm Shermans]] if they manage to hit a vulnerable point due to the APCR ammunition. It is important to avoid shots and only use the front protection as a last-hope effort, even if it is marginally better than most U.S. medium tanks at 76.2 mm thick. An important vehicle to worry about would actually be the [[8,8 cm Flak 37 Sfl.|German 88 mm Flak Half-track]]. It can penetrate the T20 the same with its 88 mm gun, but has a benefit of having extremely thin armour. The 88 mm would have an easy time taking out the T20 if it is an emplaced position and the T20 is out in the open. Avoid the 88 mm half-track's line of sight!

=== Pros and cons ===

'''Pros:'''
* 76 mm gun, reloads fast, available ammunition is good for most foes
* Smaller profile, smaller target
* Fast turret traverse rate
* Good gun elevation/depression combo
* Very mobile and fast in forward and reverse
* Sloped 63.5 mm front hull armour is resistant to most glancing shot, and can frequently ricochet when angled
* Side armour thicker than M4 Sherman (50 mm > 38 mm)
* Rear transmission and engine may help absorb rear shots to protect crew
* RP and SL boost from premium status, great for leveling through Rank III and IV vehicles

'''Cons:'''
* Armour can still be easily penetrated
* Small internal volume, one shot can easily knock out entire crew
* Machine gun port on front is a weak point
* Front ammo rack between driver & co-driver doesn't empty until no ammo is left

== History ==


===Development===
When the [[M4|M4 Sherman]] went into production in October 1941, it was considered one of the best Allied tanks of the time period. However, the observers in the North African Campaign noticed a trend in German tank development. Tanks like the [[Pz.III J|Panzer III]] were getting better frontal armour and a [[KwK 39 (50 mm)|longer 5 cm cannon]], and the same happened with the [[Pz.IV F1|Panzer IV]] when it received the [[KwK 40 (75 mm)|long 7.5 cm cannon]] as its main armament. These two tanks' improvements indicated that overtime, the Sherman itself may find itself on the shorter end of the stick, and thus plans for its successor started in Spring of 1942.<ref name="PershingHunnicutt">Hunnicutt, R.P. ''Pershing: A History of the Medium Tank T20 Series'' U.S.A.: Feist Publications, 1971</ref>

The new tank was to have superior aspects of firepower, mobility, and armour over the M4 Sherman and German counterparts, as well as the incorporation of lessons learned from the tank fighting against German forces. The new tank was one of the more technologically advanced American tanks by attempting to meet these requirements. The layout on the tank was similar as the Sherman's, with two in the front driving compartment and three in a turret. The surface area of the tank was reduced by utilizing a box design for the hull rather than sponsons, which led to equipment being stored outside the tank rather than inside it as in the M4. The tank's size was further reduced by having the transmission design be placed in the rear of the tank by the engine rather than in the front, leading to the removal of the power shaft needed to connect the front transmission on the M4 to its engine. This arrangement led to the tank having a much smaller profile than the M4. To further improve the tank, it was decided to give the tank a high-velocity [[M1 (76 mm)|76 mm gun]]. In May 1942, the first mock-up of the tank was produced, showing all its advantages over M4 Medium while keeping the same weight. Many of the observers present, including General Devers, liked the design and thus Ordnance Department continued forth with its development, designating the base vehicle as the '''T20'''.<ref name="PershingHunnicutt"/>

===Testings===
The T20 design went through many tests and variants as Ordnance try out various components and parts to see which would work best. One of the attempts was to try out different armaments as the 76 mm M1 was still new from the developmental stage, leading to the usage of guns like the [[M7 (76 mm)|3-inch gun]] on the ''"E2"'' variants from the [[M10 GMC|M10]] and a [[M3 (75 mm)|75 mm gun]] on the ''"E1"'' variants from the Sherman with an added autoloader. Transmission designs were tried as well, each with distinctive names. While the T20 designation stands for the tank with an automatic transmission, the ''T22'' had a gear box transmission from the Sherman and the ''T23'' had an electric drive derived from the [[M6A1|M6 heavy tank]]. Of all these designs, none of the "E2" variants were produced as the 76 mm M1 proved successful, and only one "E1" was built on the T22.<ref name="PershingHunnicutt"/>

Another tried component was the suspension system on the T20 designs. The T20 and T22 produced in May and June 1943 respectively had an early variant of the horizontal-volute suspension system (HVSS), which would see itself on the [[M4A3 (76) W|M4 Sherman]] in the future (The first T23 would have the standard vertical-volute suspension system (VVSS) already used on the Sherman). Tests on the tanks progressed until Armored Force recommended the usage of a torsion bar suspension system on the tanks with wider tracks. This led to the ''T20E3'' tank, the second pilot model for the T20, to be produced in July 1943 with said torsion bar suspension, though it would not be the only T20 series tank that would have the specific suspension.<ref name="PershingHunnicutt"/>

Testings with the tank in general went without much fanfare. The T20's transmission proved to be unreliable with oil leaks and overheating, but testings continued until February 1944 (T20E3 until December) when the T20 was dropped in favor of other promising designs. The T22 also encountered trouble in the transmission and engine after driving 900 miles, the continued problems also causing the T22 to be dropped in February 1944. The T22E1 design with the 75 mm auto-loading gun arrived for tests in November 1943, and though the auto-loader worked with a 20 round per minute fire rate, the insufficiency of the 75 mm gun and the questionable reliability of the auto-loader had it dropped in February 1944. Of the designs, the T23 is the one that proved promising enough for an order of 250 tanks to be placed in May 1943.<ref name="PershingHunnicutt"/>

===T23===
The T23 tank design with the rear electric transmission was rather popular in the testing grounds. A perk of the electric transmission is that the engine's performance can be varied without being in proportion with the speed of the tank, allowing for the prolonging of the engine life. Another thing the electric transmission provide is that it could be remote-controlled (though this feature was not tested for efficiency). Ten T23 prototypes arrived at Abderdeen Proving Grounds and Fort Knox for service tests around October 1943, and while the prototypes performed well compared to the other T20 series, it was deemed unsatisfactory for combat usage for its difficult maintenance attention. Another reason they refused the tank was logistics, as accepting a totally new tank without much parts commonality with their current M4 Sherman means for the retraining of tank and maintenance crew as well as obtaining a large inventory of spare parts to keep the tank in operational order. As such, the T23 was not approved for service by Armored Forces.<ref name="PershingHunnicutt"/>

T23 still saw tests and in April 1943, a recommendation came in for the T23 to be used with a torsion bar suspension system, which was done and delivered in 29 August 1944 as the ''T23E3''. After being sent to Aberdeen Proving Ground for tests and then to Fort Knox for inspection by Armored Forces, they once again refused it due to a lack in interest to the complicated electric transmission. Another test attempt was on the ''T23E4'' variant which gave the T23 tank the same HVSS as on the Sherman, however objection by the U.S. Army engineers for its excessive width and lack of attention by armoured boards once again put the T23 on hold, and kept it that way until the end of the war.<ref name="PershingHunnicutt"/>

===Successors===
With the initial rejection of the T23 by Armored Forces, it was clear that they were looking for something much more than a marginal upgrade over their existent and abundant M4 Shermans. By the time the T20 series were tested, the U.S. forces have discovered two new tanks on the battlefield, the [[Tiger H1|Tiger I]] and the [[Panther D|Panther]]. With these new benchmarks, the T20 would not be as big of an improvement over the M4 Sherman when coming up against these two specific tanks. However, not all was lost with the T20 series as Ordnance Department's tests on the tanks were incorporated into future tank designs. The T23's turret was first adapted onto the [[M4A1 (76) W|M4A1 Sherman]] to give the Sherman a 76 mm gun as the original Sherman turret with the 75 mm gun was too small for the 76 mm gun. The tested horizontal-volute suspension system on the T20s was also adapted onto the Sherman in the "E8" program, producing tanks like the [[M4A3 (76) W|M4A3E8]]. As these components, the T20's engineering feat carried on to help the American forces fight in Normandy and beyond.

The T20 still left a basis for future designs as in the production time of the T23, the preexisting request for 250 was altered for 50 of them to be modified. 40 of them to be upgraded with a [[M3 (90 mm)|90 mm gun]] and 10 more with the same gun upgrade, but with an armour upgrade as well. These programs would be called the ''[[T25|T25]]'' and ''T26''; the latter eventually becoming the approved American tank ''[[M26|M26 Pershing]]''.<ref name="PershingHunnicutt"/>

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} American medium tank {{Battle-rating|1}}. It was introduced in [[Update 1.81 "The Valkyries"]].

At first glance this tank looks very similar to the M48 and M103, since it's built on an M48 hull, but with a rather different turret. The reason for this is because it is an oscillating turret, like the ones found on contemporary french tanks like the AMX-50. The main feature which sets this tank apart from other Rank V American tanks is the automatic loader. This tank features a drum-type automatic loader, similar to the ones found on french tanks like the AMX-50 and Lorraine 40t.

Thus, the T54E1 inherits the hull armour of the M48, but combines it with a powerful 105mm gun, with an automatic loader.

== Usage in battles ==
''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

Since this tank is based on the hull of the M48, it inherits that tanks mediocre armour and top speed. But unlike the M48, this tank features a powerful 105mm gun, meaning you'll have no problem penetrating the armour of enemy tanks. Unlike tanks with the 105mm L7/M68 gun, this tank also has a powerful APBC round, which can be used to destroy opponents with weaker armour, like the Leopard I, or when shooting tanks from the side. This round, when it penetrates, is much more damaging than the HEAT-FS round because it creates much more spalling. For opponents with armour the APBC round can't pen, like the frontal armour on most Russian tanks, the HEAT-FS round is the most effective. Thanks to its very fast automatic loader this reloads almost twice as fast as most manually loaded tanks, meaning you'll be able to dish out serious damage in a very short time. It also means you're much better at recovering from a missed shot, since you'll be able to shoot again in just five seconds. You will have to make sure you won't empty the drum magazine of the automatic loader, since it takes more than 20 seconds to reload a single round from one of the other ammunition racks into the autoloader.

Knowing this, this tank is best played in a support role, destroying tanks for your teammates, but not actively participating in close-range brawls with enemy tanks. It can be used in a flanking role, but due to its mediocre top speed it's vulnerable to being flanked itself and isn't capable of reaching good ambush positions before the enemy does.

=== Pros and cons ===
''Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they have a substitution in the form of softer "inadequate", "effective".''

'''Pros:'''
* Very fast reload, thanks to its auto-loader this tank has a 5.0 second reload
* High-penetrating HEAT-FS plus a hard-hitting solid shot round
* Good acceleration
* The APDS round is slightly better than the ones found on the M60 and other 105mm L7/M68 armed tanks
* Like most other American tanks, this tank is fitted with a 50 cal machine gun, which is effective against lightly armoured vehicles and planes

'''Cons:'''
* Once the first-stage ammunition stowage has been depleted, the reload time increases drastically. This can be avoided by reloading at a capture point, since rounds replenished on a capture point automatically go into the first stage ammunition rack
* Mediocre top speed, most contemporary tanks outpace it
* The armour doesn't really protect against HEAT-FS and APDS, both of which it'll commonly face
* No stabilizer, making aiming while on the move difficult

== History ==

No sooner than the M48 Patton began being issued to armored units, American engineers already started working on potential improvements to its design. In particular, engineers focused on upgrading the vehicle’s firepower. This in turn, lead to the creation of the T54, a new vehicle based on the M48’s chassis.

Initially, two versions of prototypes were planned, but a lighter and cheaper third one was proposed in 1952. All three versions of the T54 were armed with a modified version of the T5 105mm gun, but featured different turrets and gun loading methods. The T54E1 was the second prototype, equipped with an oscillating turret similar to the ones found on contemporary French tanks, and a drum-fed autoloading mechanism with a capacity of 9 rounds.

By 1957, all three prototype versions had undergone comprehensive testing at Fort Knox and the Aberdeen proving grounds. However, as the interest of the Army shifted towards the more promising T95 project, the decision was made to cancel the T54 project in 1957. A total of less than a dozen T54s were constructed, of which two were T54E1s.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.79 "Project X"]].

The XM-1 (GM) feels like a [[M1 Abrams]], being a prototype of that very vehicle. However, its specifications encourage anything but an M1 Abrams playstyle. You want to play the XM-1 (GM) like you would play a [[Leopard A1A1|Leopard]] or a [[Ru 251]]. Use your speed, mobility, and gun to hit the weak-spots on enemy tanks armour.

One thing to note with the XM-1 (GM) is its extremely loud tracks, in some cases louder than the engine. This can be annoying, to say the least.

Unless it has all skins unlocked, it is either going to be OD Green or on desert maps a sandy yellow/brown colour. Other distinctive features on the vehicle are the combined Gunner/Commander sight is also a distinctive feature as well as the angled hull very reminiscent of the Leopards in-game. The vehicle also employs a [[hydropneumatic suspension]]. This vehicle comes with night vision for the commander and driver, and thermal sights for the gunner.

== General info ==
=== Survivability and armour ===
''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?''

''If necessary use a visual template to indicate the most secure and weak zones of the armour.''

== Usage in battles ==


This vehicle is best used as a support tank and not as a "brawler". Flanking is where this tank succeeds, using its speed and manoeuvrability to get to the rear or sides of the enemy. Another good tactic is to shoot-and-scoot to maximize the manoeuvrability and gun over an opponent.

Some enemies to be concerned about:

*T-64B(V): Aim for the drivers hatch if you facing it frontally. If possible, get around its side and hit it dead under the turret, you will blow up its ammo racks this way.
*Leopard 2K: The Leo 2K is extremely potent against XM-1's seeing as their speed and mobility is similar but the Leo has a better gun. The 2K, however, lacks sufficient armour to defeat your ammunition so hit the lower front plate or turret with M735.
*Leopard 2A4/Type 90: The hull and gun mantlets are weak spots and can be penetrated with M735. The Type 90 also has a glaring turret ring that can easily be targeted and penetrated.

=== Pros and cons ===

'''Pros:'''

* Very good speed, manoeuvrability and acceleration
* Very fast turret traverse
* Excellent manoeuvrability/speed
* Has hydropneumatic suspension control
* Not one, not two, but three secondary machine guns
* Blow out ammo rack prevents an ammo shot from destroying the tank immediately
* Driver and commander get IR vision systems, while gunner has a thermal NVD

'''Cons:'''

* Average gun against enemies
* While it has composite armour, it is useless against most weapons it will face
* Gun is sub-par; same APFSDS round (360 mm of penetration point-blank) as on the Type 74 and M60A1 (AOS)
* Front plate is made up of spaced armour, which doesn't provide the protection comparable to composite
* Similar ammo storage to the M1 Abrams, has the same side weak spot (although it is rarely exploited, due to the sub-par armour everywhere else)
* Tracks are very noisy (louder than the engine!)

== History ==


It started in the early 1970s, at the height of the Cold War and the arms race. After the joint German-American project to create the MBT-70 main battle tank was closed, and the new all-American XM803 project was deemed an insufficient and too expensive response to the newest Soviet developments, the US Department of Defense developed a new list of requirements for the future American main battle tank. Two engineering giants joined the contest: the Chrysler and General Motors companies. Both contestants decided to use the developments for the MBT-70 and XM803 to design a new tank. Many corrections and additions were made to the tactical and technical requirements of the American government, first and foremost, on the defensive characteristics of the future main battle tank. The requirements for the tank’s armour and survivability increased, along with its maintainability in the field. In addition, the Arab-Israeli conflict showed that a modern tank must have the ability to effectively destroy armoured targets at long distances, including with kinetic shells, and also have a sufficiently large complement of shells. In spite of the changes and additions to the technical specification, the contestants managed to achieve their goals, and by 1976, they presented their developments, the experimental prototypes of the XM-1 tank, for testing. Both vehicles were outwardly very similar, with practically identical dimensions. They were alike in their layouts and used the same 105 mm M68 rifled cannon. Both tanks turned out very well. Which prototype did the military choose, and why?

The XM-1 (GM), the contest model from General Motors, became a further development of ideas and technological solutions for the MBT-70 and XM803 projects, including the diesel powertrain and mixed undercarriage with six roller wheels per side, three with hydraulic suspension and three with torsion bar suspension. The competitor to General Motors, the Chrysler company, used their XM-1 (C) model to present not only a progressive gas-turbine engine but also a new undercarriage with seven independent roller wheels on each side with individual torsion bar suspension. In addition, the Chrysler engineers were able to save funds on constructing the tank by optimizing the components of the aiming equipment and the gun stabilization system. These details played a decisive role in the selection of the contractor to make the XM-1 project a reality. In spite of the fact that numerous flaws and “teething problems” arose during the project, the prototype for the USA’s next-generation main battle tank was confirmed. After several cycles of correcting issues and modernizing the prototype XM-1 (C), the first vehicles began to be deployed under the designation M1 Abrams.

=== Survivability and armour ===
''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?''

'''Armour type:'''

* Spaced armour (Hull front, Turret front)
* Rolled homogeneous armour
* Cast homogeneous armour

'''Notes:'''

* Road wheels are 20 mm thick and tracks are 30 mm thick.
* A 6.35 mm RHA plate separates the engine from the crew compartment
* The crew is protected by a 6.35mm thick turret basket
* Hull spaced armour configuration is 38 mm RHA + 127 mm air + 51 mm RHA.
* Turret spaced armour configuration is 38 mm RHA + 127 mm air + 127 mm CHA.
* Turret rear side spaced armour configuration is 12.7 mm RHA + 38 mm air + 25.4 mm RHA
* Turret rear spaced armour configuration is 12.7 mm RHA + 38 mm air + 12.7 mm RHA.

''If necessary use a visual template to indicate the most secure and weak zones of the armour.''

The XM308's frontal armour is only effective versus full-caliber AP and APHE rounds and certain APDS rounds. Almost all large caliber (76 mm and up) have no trouble slicing through it, even when hitting the frontal armour at an angle. Large caliber HEAT-FS too, has no problem going through, although the large fuel tank behind the frontal hull armour can sometimes absorb most damage. Because the armour has a layer of air in it, it is very effective against HESH rounds. All the spalling generated by the HESH round when it hits the first plate will get absorbed by the plate behind it. One big weakspot on the turret it the left (when facing it) turret cheek. This is because this part of the turret is not protected by spaced armour and only consists of 177.8 mm thick CHA plate, which most chemical and kinetic energy projectiles can penetrate with ease.

The mobility of the vehicle is worse than that of the MBT-70. In its stock configuration, it has a horsepower/ton ratio of 21.39, while with all upgrades this increases to 24.08 HP/T. The top speed (both forward and reverse) is 64 km/h (40 mph) with 8 gears for both directions. The tank can reach its top speed quickly on flat roads, while on more difficult terrain the top speed drops by around 20 km/h. The tank has neutral steering and good turning ability on all terrains.

== Usage in battles ==
''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

The XM308, like the MBT-70, is a very good flanker. To get the most out of this tank you must use its high speed and acceleration to flank the enemy or set up ambushes. Its gun and ammunition is good enough to penetrate most lower BR tanks with ease, although when uptiered you will have to resort to aiming for the weak spots of opponents. The HEAT round you get is free, and will easily penetrate tanks with plain steel armour, but it's lacking when facing tanks with composite armour, and it has rather mediocre muzzle velocity, making aiming and leading at longer ranges more difficult. The APFSDS round has decent penetration, and will penetrate most opponents with relative ease. It also has very high muzzle velocity, almost 1.5 km/s, making aiming even at longer ranges easy. The ATGM is very useful and free, it's very good at long ranges, and is very effective against stationary or slow moving helicopters.

While the armour may seem impressive at first, it won't protect you against most guns at and around its battle rating. Most tanks at this rank have acces to powerful APFSDS and HEAT-FS rounds, which have no trouble penetrating you. Knowing this, you mustn't rely on your armour to protect you.

=== Pros and cons ===

'''Pros:'''

* Stock ammunition consists of the good MGM 51C "Shillelagh" Guided Missile, means no ammo costs for using it, plus a decent but inferior HEAT Shell.
* Has access to APFSDS Shells with 346 mm of penetrating Power on a 90° angled armour plate @ 10m.
* Good mobility and acceleration, high speed both forwards and backwards
* Top mounted 50 cal can allow you to damage low-flying aircraft
* Frontal Fuel tank behind the spaced armour which can sometimes absorb enemy chemical energy rounds
* Since this tank has an autoloader, loosing a crewmember will not impact the reload speed, and it still functions when putting out a fire

'''Cons:'''

* Long reload on the gun (10 seconds) which cannot be improved since it is an autoloader
* The spaced armor is not composite armor and cannot provide adequate protection against most guns of its rank
* Weak sides and LFP
* Ammo racks are large and can be easily hit, and does not have blowout panels
* Vulnerable to the rear due to raised engine deck
* Cramped interior, loss of more than one crew member more likely when penetrated
* Does not have access to the roof-mounted 20 mm like the MBT-70 which could be very useful in certain situations

== History ==

Once it became apparent that the MBT-70 project was doomed to fail in the early ‘70s due to high costs and reliability issues, the U.S. Congress decided to cut their losses on the project by cancelling the MBT-70, and instead, diverted funding to the development of a new project called XM803.

The XM803 was, in essence, envisioned to be a “budget version” of the MBT-70. Although the new vehicle would heavily be based on the MBT-70, inheriting many of its design solutions, it would also try to drastically reduce production costs by using more conventional and only American-made parts. Although this meant that the XM803 had to give up some of its high-tech equipment in favor of lower production costs, it was projected that the influence of these changes on the XM803’s combat performance would be minimal.

Despite showing favorable performance and being seen as a promising design by the Army, the XM803 still remained a comparably expensive tank to produce even with the applied changes over the MBT-70. Moreover, neither the MBT-70 nor the XM803 seemed to offer any substantial increase in combat performance over the already in service M60 Patton to justify the high production cost. This ultimately led to the Congress cancelling work on the XM803 only a short while after the cancellation of the MBT-70. In the late 1970s, some funding of the two failed projects would later on find its way to support the development of an entirely new, but this time around, more conventional tank project. That tank of course being the legendary M1 Abrams itself.
