== Description ==

The '''T77E1 Multiple Gun Motor Carriage (MGMC)''' is an American self-propelled anti-aircraft gun mounted on the [[M24|M24 light tank]] chassis and armed with six 12.7 mm M2HB machine guns. Development began in July 1943 using the hull of the M24, which was still in development and designated as the T24. This SPAA was designated as the '''Carriage, Motor, Multiple, Cal. .50 Gun, T77''', and was armed with four 12.7 mm machine guns. The design was approved for a mock-up by the end of 1943. After inspecting this mock-up, officials requested that two additional machine guns be added to the vehicle. The first T77 was completed in July 1945, and a second prototype was also made and designated as the T77E1. However, by this time World War II had already ended. The T77 never saw active service and the two prototypes were presumably soon scrapped.

The '''T77E1''' was introduced in [[Update "Firebirds"]], and as it is based off the M24's light tank hull, it is a very light and mobile vehicle. The .50 cal armament can potentially be useful against armoured targets on the ground, though it is not ideal to engage with tanks at its battle rating and its thin, though angled, armour. With some good precision, you can easily take down enemy aircraft with your numerous machine guns.

'''Armour type:'''

* Rolled homogeneous armour (hull, turret)

{| class="wikitable"
|-
! Armour !! Front (Slope angle) !! Sides !! Rear !! Roof
|-
| Hull || 25.4 mm (60°) (upper glacis) 25.4 mm (44°) (lower glacis) || 25.4 mm (12°) (front portion) 19.05 mm (12°) (back portion) || 19 mm || 12.7 mm
|-
| Turret || 12.7 mm || 12.7 mm || 12.7 mm || 12.7 mm

'''Notes:'''

* Suspension wheels and tracks are 15 mm thick.

The T77E1 uses the M24's chassis, which is lightly armoured all around and can be potentially susceptible to enemy fire if used closer into the battlefield. Though this vehicle is armoured on top, it is still vulnerable to planes strafing and close air support, especially planes with autocannons or bombs.

=== Mobility ===
{{Specs-Tank-Mobility}}


{{tankMobility|abMinHp=420|rbMinHp=262}}

Like the M24, the T77E1 is pretty fast and mobile. Though the acceleration can be slow, the top speed of this vehicle is high, as well as its reverse speed, both of which may allow you to pull out of a rough situation very quickly and easily. While using this tank against ground targets might not be the best decision, if you do find yourself in a fight with one, flanking enemies and using this vehicle's mobility to its advantage may help you to get the best outcome in a battle.

== History ==

During World War II, the US Army mainly utilised self-propelled anti-aircraft guns based off the M3 half-track, such as the M13 and M16 Multiple Gun Motor Carriages (MGMC). These half-tracks were effective and used multiple .50 cals (12.7 mm machine guns) on a power-operated turret. Even though these half-tracks were useful, the US Army ideally wanted full-tracked vehicles so as to have the potential mobility of a tank. Attempts at a full-tracked anti-aircraft vehicle included four .50 cals mounted on a Mark 17 gun mount and fitted onto the hull of an M3 Stuart light tank, which at the time was widely used by the Allies in World War II. This design, developed in 1942, was rejected, however.

With the development of the T24 prototype light tank (later standardised and redesignated as the M24 Chaffee), work had already begun developing an anti-aircraft vehicle based off the T24 in July 1943 and it was designated '''Carriage, Motor, Multiple, Cal. .50 Gun, T77'''. The M24 proved to be very effective in Europe later on during World War II, so an anti-aircraft vehicle based off this design seemed promising. Initially, the T77 was to be mounted with four 12.7 mm machine guns on the T89 quadruple gun mount, developed by the United Shoe Machinery Corporation with some help from the US Army Air Forces. This mount was fully powered and could be operated remotely to reduce muzzle flash from preventing the gunner from seeing clearly. By the end of 1943, the design was approved for a mock-up to be made, which was finished by December and inspected by military officials who requested that two more 12.7 mm machine guns be added to the vehicle.

In April 1944, two prototypes of the T77 were ordered after these changes were made. One of the two prototypes was finally completed in July 1945 and had a crew layout similar to the original M24 Chaffee light tank, albeit without a tank loader, as well as a hull-mounted .30 cal (7.62 mm) machine gun that a machine gunner could operate, just like on the original Chaffee. The hull design and armour of the T77 was practically the same as that of the M24, the only notable difference overall being the turret, obviously equipped with the machine guns, as well as the circular hatches that the gunner and commander sat into. After the first T77 was completed, it was taken to the Aberdeen Proving Ground for further evaluation and testing. The second prototype – designated the T77E1 – was also completed and had an advanced fire control system, as well as clear acrylic domes covering the gunner and commander hatches, compared to the first prototype.

These two prototypes would have been a good design that could have potentially entered service, though this never did take place as World War II ended before the T77 or T77E1 could see active service, and both prototypes were presumably scrapped.

One of the two prototypes were finally completed in July 1945 and had a crew layout similar to the original M24 Chaffee light tank, albeit without a tank loader, as well as a hull-mounted .30 cal (7.62 mm) machine gun that a machine gunner could operate, just like on the original Chaffee. The hull design and armour of the T77 was practically the same as that of the M24, the only notable difference overall being the turret, obviously equipped with the machine guns, as well as the circular hatches that the gunner and commander sat into. After the first T77 was completed, it was taken to the Aberdeen Proving Ground for further evaluation and testing. The second prototype – designated the T77E1 – was also completed and had an advanced fire control system, as well as clear acrylic domes covering the gunner and commander hatches, contrast to the first prototype.

These two prototypes would have been a good design that could have potentially entered service, though this never did take place as World War II ended before the T77 or T77E1 could see active service, and both prototypes were presumably scrapped.

== Description ==

The '''T77E1 Multiple Gun Motor Carriage (MGMC)''' is an American self-propelled anti-aircraft gun mounted on the [[M24|M24 light tank]] chassis used by the U.S. Army during World War II. It was armed with six 12.7 mm M2HB machine guns. This anti-aircraft vehicle began development in July 1943 using the hull of the M24, which was still in development and designated as the T24. This SPAA was designated as the '''Carriage, Motor, Multiple, Cal. .50 Gun, T77''', and was armed with four 12.7 mm machine guns. This design was approved for a mock-up by the end of 1943. Though after inspecting this mock-up, officials requested that an additional two machine guns be added to the vehicle. The first T77 was completed in July 1945, and a second prototype was also made and designated as the T77E1. Though after these two prototypes were built, World War II had already ended and the T77 never saw active service and were soon presumably scrapped.

The '''T77E1''' was introduced in Update "Firebirds", and as it's based off the M24's light tank hull, it is a very light and mobile vehicle. The .50 cal armament can potentially be useful against armored targets on the ground, though it is not ideal to engage with tanks at its battle rating and its thin, though angled armor. With some good precision, you can easily be able to take down enemy aircraft with your numerous amount of machine guns this vehicle is equipped with.

The T77E1 uses the M24's chassis, which is lightly armored all around and can be potentially susceptible to enemy fire if used closer into the battlefield. Though this vehicle is armored on top, it is still vulnerable to planes strafing and close air support, especially planes with autocannons or bombs.

=== Mobility ===
{{Specs-Tank-Mobility}}  {{TankMobility|abMinHp=420|rbMinHp=262|AoAweight=}}

As is the M24, the T77E1 is pretty fast and mobile. Though the acceleration can be slow, the top speed of this vehicle is high, as well as its reverse speed, both of which may allow you to pull out of a rough situation very quickly and easily. Though using this tank against ground targets might not be the best decision, if you do find yourself in a fight with one, flanking enemies and using this vehicle's mobility to its advantage may help you to get the best outcome in a battle.

== 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 instead 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).''

=== Pros and cons ===
''Summarise 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 - use substitutions with softer forms such as "inadequate" and "effective".''

== History ==

=== Development ===
During World War II, the U.S. Army mainly utilized self-propelled anti-aircraft guns based off the M3 half-track, such as the M13 and M16 Multiple Gun Motor Carriages (MGMC). These half-tracks were effective and used multiple .50 cals (12.7 mm machine guns) on a power-operated turret. Even though these half-tracks were useful, the U.S. Army ideally wanted full-tracked vehicles so as to have the potential mobility of a tank. Attempts at a full-tracked anti-aircraft vehicle included four .50 cals mounted on a Mark 17 gun mount and fitted onto the hull of an M3 Stuart light tank, which at the time was widely used by the Allies in World War II. This design, developed in 1942, was rejected, however.

With the development of the T24 prototype light tank (later standardized and redesignated as the M24 Chaffee), work had already began and developing an anti-aircraft vehicle based off the T24 in July 1943 and was designated '''Carriage, Motor, Multiple, Cal. .50 Gun, T77'''. The M24 proved to be very effective in Europe later on during World War II and so an anti-aircraft vehicle based off this design seemed to be doing well and solid. Initially, the T77 was to be mounted with four 12.7 mm machine guns on the T89 quadruple gun mount, developed by the United Shoe Machinery Corporation with some help from the U.S. Army Air Forces. This mount was fully powered and could be operated remotely to reduce muzzle flash from preventing the gunner to see clearly. By the end of 1943, the design was approved for a mock-up to be made, which was finished by December and inspected by military officials, who requested that an additional two more 12.7 mm machine guns be added to the vehicle.

On April 1944, two prototypes of the T77 were ordered after these changes were made. One of the two prototypes were finally completed in July 1945 and had a crew layout similar to the original M24 Chaffee light tank, albeit without a tank loader, as well as a hull-mounted .30 cal (7.62 mm) machine gun that a machine gunner could operate, just like on the original Chaffee. The hull design and armour of the T77 was practically the same as that of the M24, the only notable difference overall being the turret, obviously equipped with the machine guns, as well as the circular hatches that the gunner and commander sat into. After the first T77 was completed, it was taken to the Aberdeen Proving Ground for further evaluation and testing. The second prototype – designated the T77E1 – was also completed and had an advanced fire control system, as well as clear acrylic domes covering the gunner and commander hatches, contrast to the first prototype.

These two prototypes would have been a good design that could have potentially entered service, though this never did take place as World War II ended before the T77 or T77E1 could see active service, and both prototypes were presumably scrapped.

== Description ==

The '''{{Specs|name}}''' is a premium gift rank {{Specs|rank}} American medium tank {{Battle-rating}}. It was introduced in [[Update 1.79 "Project X"]]. The XM-1 (Chrysler) is an Xbox One exclusive vehicle, only available from the [https://www.microsoft.com/en-us/p/war-thunder-xm-1-chrysler/bxntjdjgsk54?activetab=pivot:overviewtab Microsoft store].

== General info ==
=== Survivability and armour ===
{{Specs-Tank-Armour}}

The armour on this vehicle is not very good. Most APFSDS at this rank will have no issue penetrating the armoured zones with ease. Despite there being spaced armor in the front of the tank, the driver is also located here behind and surrounded by three exterior fuel tanks, and can be fairly vulnerable to even APDS shells at lower tiered tanks, such as the M60 or T54E2. In a down-tier, you will be able to soak up some damage when being hit by weaker rounds, but not much.

'''Armour type:'''

* Spaced armour (Hull front)
* Composite armour (Turret front)
* Rolled homogeneous armour
* Cast homogeneous armour (Gun mantlet)

== Usage in battles ==


This vehicle is best used as a support tank to flank and knock out other tanks from their flanks and not as a "brawler". Instead of charging full speed into the enemy head on. This tank is best suited to attacking from the flank. 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.

This tank can also be used to devastating effect in urban combat. In urban combat, it is advised that you never go alone, stay with or behind friendly tanks, and do not rush forward. If you play an ambush and defensive style of combat, at least at the beginning of the match, it is likely you will be able to get multiple kills/assists and should be able to stop the enemy push. If your team is winning, and the enemy is outnumbered, it may be possible to push forward quickly but cautiously, in order to flank and catch enemies off guard, hopefully securing victory for your team.

The survivability of the XM-1 (Chrysler): The XM-1 has relatively weak armour, but it is oddly survivable. It is somewhat rare to get killed by a single shot when playing the XM-1. Usually, it takes two or more shots to take it out, thanks to the spacey interior, and the blowout ammo racks in the turret. However a single HEATFS hit will render you knocked out of the fight.
Sometimes it takes up to 10 badly aimed or unlucky shots to take out the XM-1, this is especially true for long-range shots. To further increase the survivability odds, use the terrain to cover you, after firing a shot reverse back and pop out again like a jack in a box. The excellent mobility of this fine tank allows for this to achieved, and used well it can turn the tide of a impending defeat to a victory.

Some enemies to be concerned about:

[[T-64B]]: 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.

=== Pros and cons ===


'''Pros:'''

* Very good speed, manoeuvrability and acceleration
* Very fast turret traverse
* Excellent manoeuvrability/speed
* Not one, not two, but three secondary machine guns
* Blow out ammo rack prevents an ammo shot from destroying the tank immediately

'''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 RISE (P)
* 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.
