Extended Beam Barrel:
Mega Beam Cannon:
The strongest weapon of the Tallgeese III is its mega beam cannon, which replaces the old dober gun used on the previous two models. It has two modes; a compact configuration, which functions like a beam rifle, and barrel extended, which forms a powerful beam cannon. The beam cannon mode is among the most powerful mobile suit beam cannons and nearly as powerful as the twin buster rifle of the Wing Zero. Its raw strength was displayed when one shot was enough to destroy the asteroid base MO-III. It takes a bit of time to charge and more energy to shoot.
2 Beam Sabers:
Stored within the shield, Focuses a beam into a sword shape that cuts through even Gundanium alloy.
Twin Linked Vulcan Cannons:
A new addition to the armament of the Tallgeese series is a set of head-mounted vulcan guns. These guns can be used to shoot down enemy suits at close range or incoming missiles.
Shield w/Retractable Heat Rod:
Like the previous two models, the Tallgeese III mounts a shield with anti-beam coating on the left arm's shoulder joint for defensive purposes. Unlike its predecessors, however, the shield also mounts a retractable heat rod, similar to the one previously used on Zechs' OZ-13MS Gundam Epyon.
Retractable Heat Rod:
A segmented whip-like projected chain housed in Tallgeeses' shield. Deactivated, it can be used to trip or entangle an opponent. When activated, the material becomes super-heated, allowing it to cut and burn through armor. A single swipe with this weapon can destroy up to three Leos.
System Features:
Self-Destruct System:
In case of the Tallgeese in danger of being captured, the mobile suit is built with a self-destruct system to destroy the mobile suit and prevent any data from being obtained.
High Power Boosters:
Boosters that allow up to very high speeds and very high maneuverability. However, the powerful boosters put a lot of strain on the pilot, resulting in a burden of about 15 Gs.
G-Dampeners:
Dampen the G-forces so that the pilot notices almost nothing of extreme G-forces
Interface System
The Interface System decreases the pilot's reaction times as there is no need for traditional visual interfaces. Furthermore, thanks to the advanced computations performed by the computer, the pilot can become aware of future outcomes and possible courses of action that can be taken to achieve total victory or total defeat. However, due to this direct brain interface, as the human brain cannot process the raw data, if it is used for too long the system will cause the pilot to vividly "hallucinate" the possible paths that the pilot can take; as the pilot tries to figure out what is going on, the system can overload the brain with too many statistics and estimated values, causing temporary insanity.
