With the implementation of SP1.9 and later versions and the liberation of design ideas, VX Strikeers finally ushered in a new life. First of all, its ground mech form has acquired the ability to step on the spot or move slowly to adjust the body's aiming posture. And because of the changes in the version, the cannon was finally acquired as a means of tactical strikes. Finally, because of the liberation of the design ideas and the use of the remaining action bars, it obtained additional camera missiles for precision guided strikes, especially on the ground stealth targets. Coupled with the extremely outstanding hovering ability, it has become the unique role of the armed helicopter of the Red Alert 3 Rising Sun Imperial Army.
