The Dragunov will be the primary weapon used by the Soviet Sniper. It will work basicly the same as the Allied Enfield. Meaning it will kill basic infantry in 2 shots, and more depending on what you're trying to kill. A headshot will still kill any infantry of course.
This new mode was actually a TC for Red Alert. It will replace several units, and also replace and change weapons on current units. In turn changing the gameplay.
A Hum-vee will replace the Ranger, the Bradley IFV will replace the Light Tank, Rocket soldiers will be available to both teams, and most tanks will also be armed with Machine Guns. That is just a sample though, much more is also being changed in the Real War mode.
