I understand OP, as I used to have this problem too. But since I gave up micromanagement I've solved that problem. Also I found the charisma of Soviet. In my personal experience, Soviet tanks were perfectly fine, if not overwhelmingly superior, in tank battles within 800 metres. NATO spotting magic only beats the Soviet at a distance. Once the Soviet tanks got close(within 1000 metres), the m60's pathetic gun and armour could not save them.
Focusing on whether a particular tank can see enemy tanks is a form of micromanagement. For the Soviet player, micromanagement means nothing. You just need to get enough tanks moving in the general direction of the enemy position. Mass will solve the problem of blindness for you.
And don't forget artillery bombard. Soviet can't live without battery.
