I noticed that the Russians like surrounding or ambushing their targets; prime example when they killed the commander when he was driving his jeep before the battle at Montignac. They also like attacking from a wooded area; prime example is After Montignac is when Morton was overrun, their infantry units came from the woods with the help of armored vehicles. Hope this helps.

I managed to finish the mission and I only killed 2 Russians. You just need to stay low and sneak through the forests. Thats how I did it. But I don't think you can finish the mission without killing more than 1 Russian. Maybe there is a way to finish it without killing Russians.
