An enhanced version of the domestic anti-aircraft machine gun armament.
Although it has a triple mounting of the 25mm high-angle machine gun, it does not shoot simultaneously, but one by one in order to prevent the barrels from overheating.
In addition to the standard twin mounts and temporary single mounts, this 25mm triple machine gun formed the core of close-range anti-aircraft armament.


Anti-Aircraft Gun AA Guns are equipable in RE. They are mainly used to provide "Anti-Air", notably via their AA Anti-Air stat. They:

  • Are notably required in most AACI.
  • Trigger a tracer-fire effect during air combat.
  • Bring an accuracy bonus against PT Imp.

"AA Rocket Launchers" may be described and displayed differently, they still behave like regular AA guns.
