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 maneuverability as well as the maximum speed forward and backward.

Usage in battles

In RB the Quadruplo is best used in the front lines to kill tanks and other SPAA's from the side. Aggressive play stiles are suggested to get the most out of the Quadruplo. when it comes to shooting down planes in the Quadruplo, it is best to get their attention so they try to strafe, this will make them an easy kill because of your high rate of fire and closely mounted guns (hence the nickname "discount Wirbelwind").

Pros and cons


  • PzGr 40 shells are great at penetrating tanks from the sides and knocking out modules
  • High mobility when spaded
  • Great armour for a SPAA
  • Guns have a very high rate of fire
  • Guns are placed very close together
  • 4 crew members


  • PzGr 40 is tier IV modification
  • Performance is inadequate when stock
  • Gap in the gunner's position of the turret armour
  • Turret can be penetrated by .50 cals heavy machine guns
  • High rate of fire makes it more difficult to adjust fire against planes


A prototype AA tank based on the M15/42 medium tank. The single prototype was captured by Germany upon Italy's surrender in September, 1943. Some sources have claimed it served as inspiration for the German Wirbelwind AA tank, which first saw service in mid-1944.
