Russia and Ukraine

As I said over at AD. The Russian army environment is probably the most brutal in existence. Always was, going back to imperial times. A soldier's life isn't worth shit. As is shown by the horrendous losses they sufferend in WWII.

The Red Army lost 9,7 million men on one single front. The Germans lost 5,5 million on numerous fronts. The Soviet Union or later Russia also have the highest suicide rate of all armies.
