Well, aircraft weren't equipped with icons either. They are compensating for info a real pilot would have, but we do not due to technical limits.
Same for a gunner in a tank. He would be much able to track his turret rotation relative to the hull much better than we do.
Icons compensating true. Due to the fact that a computer screen cannot reproduce all that the eye can see in real life.
So a GV gauge would be compensating for the gunner, you, who is now the driver, seeing and
knowing which way the gun is pointing? In effect, compensating for poor SA?
oh just forget it then

Naaaa. Don't give up. I for one just enjoy trying to play Devil's Advocate.
