With the increasing maturity of SP 1.9 and later versions, the old SteelRonin has no way to adapt to the new combat environment.
Therefore, the subsequent upgrade of the Iron Werewolf was cancelled and replaced with a super stronghold.
The Giga Fortress is the most powerful combat unit in the history of the Empire in Red Alert 3, and it is also one of the weirdest weapons in the world's military history in the Red Alert series.
It has two combat forms. When in the sea form, it is a huge water defense fortress with radar stealth capability. When it is in the air, it is a non-stealth advanced heavy bombing unit.
Therefore, its operational thinking is that when the empire is at a disadvantage in air defense or has not obtained air dominance, it will stay on the water to maintain air defense. When the empire obtained maritime air supremacy and began to advance inland, it could consider deforming into the air in the form of strategic bombing.

Operatings:

AG1 Waterform bridge turret control (Cam1&2,Pitch and Roll control the aiming of the bridge turret)

AG5 Anti-air missiles online
AG6 Flying model turrrts activated (Cam4&5 Pitch and Roll control the aim of the main guns)

AG4 Water form navigation control (Thorrtle starts the engine, Yaw controls the turning, and simultaneously starts AG4 and AG7 on the water as the reverse gear for fortress navigation)
AG7 Airborne flight control (Thorrtle starts the engine, VTOL controls the pitch, Yaw and Trim control turns, LandingGear is the watertight cabin telescopic)
AG8 Form conversion fortress take-off and landing control (AG4 or AG7 must be in the active state when transitioning between the two modes)

Big Toy!Enjoy it!
