I also tried the Russian demo and my impression was that there are some serious issues concerning spotting and accuracy (in an otherwise excellent game).
I had situations where my infantry went from crawling (undetected) to sprinting upright and was killed *instantly* by rifle and mg fire - from 700 meters distance and through several patches of woods! The enemy infantry didn't even need time for spotting and acquiring their targets.
Sometimes spotting seems to be ridiculously easy (like in the above case or when entrenched guns that didn't open fire at you are already spotted from long range) and at other times frustratingly difficult (when you are lucky if an anti-tank gun continuously firing at you and taking out your tanks is at least marked as a sound contact).
Infantry survival was so bad in the demo (even when positioned in trenches) that i mainly used them as expendable spotting teams and spare crew for anti-tank guns.
Hopefully these problems can be addressed, but since they were already present in TOW2 I am a bit sceptical.
