Now I'm not saying this ability is OP or anything but this does make this unit be a little too self sufficient. This almost counter acts it's weakness being slow and turret less if it can see nearly 20 range before it's intended target can shoot.
Even though I consider the SU85 to be the most balanced TD out of all of them this still bothers me a little. I think this vision ability should be removed or at least nerfed. This units weakness is that it need combined arms but the ability makes it self sufficient. Now that the soviet pop cap efficiency is a thing I think this ability should be looked at a bit.
