In one instance I was moving a German tank platoon down a road. There was a small patch of woods ahead and as soon as the point tank emerged from the tree line it was welcomed by a well placed Russian AT gun.
AT ambush, 10 meters ahead.
Take a look at the figure below, taken from the "Training Directives for the Light and Medium Tank Companies, March 1939".
The square inside a circle represents a tank and the other symbol an AT gun (you may recognize from APK43). Left side (wrong), the tank at the edge of the trees gets nailed by an AT gun. Right side (correct), the tank steps aside the road and spots the AT gun from the cover of the foliage.
Put those trees to work for you. Russian AT gunners don't have IR imaging. A German tank takes a peek at the open terrain ahead from the concealment offered by the trees.
