There is quite some of things to do to stay away from trouble in a tank, else you cover is out of the window, and soon you will be in a steel coffin, incinerated:
This is what I learned during my years in tanks :
Tracks reveal you, either the area should be full of tracks going everywhere or you better not showing your tracks at all, always travel in safety, never in the open.
When you shoot, you must scoot, the flame is intensive and short, but the smoke stay there for some time.
When you move, you will be detected at very long range if not obscured totally by trees.
Bad weather/night is you best friend against planes.
Wirbies / Ostwind / M16 should have range icons for planes omitted, it is basically a ranging computer, something unheard of in the 40's.
