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 armor 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 armored 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?

Description

GarageImage XM1 (GM).jpg


The Tank, Combat, Full-Tracked, 105-mm Gun XM1 (GM) is a gift rank VI American medium tank with a battle rating of 9.3 (AB/RB/SB). 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 a M1 Abrams playstyle. You want to play the XM-1 (GM) like you would play a 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 color. Other distinctive features on the vehicle is the combined Gunner/Commander sight is also a distinctive feature as well as the the angled hull very reminiscent of the Leopards in-game. The vehicle also employs a hydropneumatic suspension.

General info

Survivability and armor

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 maneuverability 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. Your best bet is to flank the Leo and hit it in the side and or engine. Otherwise try to hide.
  • Leopard 2A4/Type 90: Unless you get around to its side, there is very little you can do to destroy this beast.

Pros and cons

Pros:

  • Average gun against enemies
  • Very good speed, maneuverability 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:

  • 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 armor 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 armored 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.
