(RA2 & Yuri's Revenge)
Ok, so what is your favorite unit or building?
I prefer the Allied Battle Fortress, you can put a lot of chrono dudes in there and rip up some buildings very quickly.
And on the Soviets I love the Flak Trak for its speed and mobility and ability to carry up to five troops.
On the Yuri side I dig the Master mind for its unlimited but quick use of the mind control technology.
