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.


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


Main armament

Main article: M168 (20 mm)

A 20 mm VADS, or Vulcan air defence system. Used initially during the Vietnam war, it was a 20 mm air-cooled minigun attached to a small turret on the M163. Dangerous to anything in the sky, it will lock on and rip through anything in its path.

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).


Main article: AN/VPS-2

The M163 is equipped with an AN/VPS-2 tracking radar, with no search radar. The radar is fitted to the side of the turret.

Pros and cons


  • Amphibious
  • Quick acceleration
  • Good traverse, especially when fully upgraded
  • Insane rate of fire of 3000 rpm; can literally shred incoming enemy aircraft.
  • Has a tracking radar


  • Light armour
  • Not keen to climbing hills until performance modules are equipped
  • Relatively slow for the rank
  • Slow in water
  • Inaccurate/wobbly in water
  • One of the longest rearm/reload times in the game
  • No search radar


The VADS was used during the Vietnam war and onwards and was based on the chassis of the M113 armoured personnel carrier. NATO used it as an anti-aircraft gun platform.


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