A heavy weapon variant of the AMS-119 Geara Doga, the AMS-119 Geara Doga Heavy Armed Type is outfitted with a heavy armament backpack in place of the normal backpack. This new backpack has two large propellant tanks for increased operational time, a Lange Bruno Gun for long-range support purposes, and enhanced propulsion system to compensate for the added weight. Other than these changes, the Geara Doga Heavy Armed Type is the same as the standard Geara Doga. A similar set-up was later used by the AMS-129 Geara Zulu (Angelo Sauper Use).
Despite having a new mass production mobile suit, the AMS-129 Geara Zulu, the Neo Zeon remnant group Sleeves still operated several Geara Doga Heavy Weapons Types. These machines were painted in a new color scheme and given the distinctive markings featured on many of the mobile suits used by the Sleeves.
