Soviet Hero: Boris
Boris is highly effective against infantry, thanks to his rapid rate of fire. Rather than using C4 charges to eliminate structures, Boris is able to call in an air-strike of MiG fighters to bombard any structure he targets with his laser designator. Boris is immune to psychic control and can not be crushed by vehicles, except by one special new unit, the Allied Battle Fortress. Be warned though, as only one Boris can be trained at a time.
With the creation of the Siege Chopper, the Soviets now have quick strike capabilities from the air. When flying, this vehicle is mobile and effective against enemy infantry units. When deployed, the Siege Chopper lands and reveals a massive weapon capable of quickly destroying buildings and stationary targets from long range.
When the Soviets place a Radar, they immediately begin development of their new Spy Plane. When fully charged, the Spy Plane can be deployed anywhere on the map. As it passes over the targeted terrain below, it reveals the shroud, allowing the Soviets to see new areas of the map.
