Adding Hold Fire to all units would be a usefull addition.
Also tanks shooting at your units out of your line of sight shouldnt be revealed when they fire at you, something like Combat Muffin suggested would be much better.
I'm generally disappointed with true sight when it comes to armored vechicles I was hoping that their sight will be more limited, something similar how it was in Men of war, (no 360-degree vision) it would force players to use tanks in combination with their infantry.
If Soviets get an ability thats similar to AWM, then it will be less powerfull in Coh 2 because Wehrmacht units will gain veterancy normaly, so if u rush in tanks and lose them then u also feed the German with vet.
