Their units include mini gunners, same as the allies, grenadiers that pack a painful punch against walking and driving opposition, flame troops for char grilled allies, bazooka men, same as the allies, and engineers with the same conditions as the allies. These German Shepherds won't fetch for you as they are very fast and will tear a man apart with one bite, but the armored side is where the Russians rule supreme. Their smallest tank, the heavy tank has 1.5 times the armor of the allies largest tank and two barrels instead of one, moves as fast as the allied Medium tank and is only 94 credits more expensive. With two turrets and anti-personnel missiles, they tend to plunder their way through most any base. In the realm of the air, the Russians have yaks that strafe the ground with machine guns removing any troop threat, migs that are three times faster than choppers and can deliver their payload of five missiles at once.
Spy planes can uncover the map, and paratroops and parabombs can bomb the unsuspecting base.
Westwood were obviously on a roll with the Russians and decided not to stop, also at their disposal are Chinooks for ferrying troops and Hind anti-personnel choppers. The only real technological breakthrough the Russians received is in a device known as the Iron curtain. This will make any unit invulnerable for 30 seconds. In the solo missions, these stats won't really make a big difference. The missions have been designed and play tested well to allow for excellent balance, and never frustrating despite the difference in units.
