The Soviets specialize in raw power through large armored units and nuclear weapons. They can also build at much cheaper prices.
Note about certain units
Airbase planes can only be built after a Tech Airbase is captured, and Air War planes can only be built in the 'Air War' skirmish mode. Super-units can only be built in the 'Total Armageddon' mode.
