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 helpfull for survival in combat?

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


Write about the mobility of the ground vehicle. Estimate the specific power and maneuverability as well as the maximum speed forward and backward.

Usage in the 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).

Pros and cons


  • Has spaced armor
  • 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 380 mm of penetrating Power on a 90° angled armour plate @ 10m.
  • Extremely fast in both forwards and reverse.
  • Fast acceleration.
  • Top mounted 50 cal can allow you to damage low-flying aircraft
  • Lower battle rating than MBT-70 despite only minor changes


  • 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 20mm on the MBT-70 which could be very useful in certain situations


By 1969, the MBT-70 project was over five times more expensive than planned. West Germany backed out of the join project in 1970 to focus on developing what eventually became the Leopard 2; meanwhile the United States attempted modifying existing MBT-70 designs and prototypes to reduce production costs. The result was the XM803, although it was ultimately just as complex and expensive as the MBT-70. The project was cancelled in 1971, with funds being re-allocated to the XM-1 program.


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
