Trying to picture actual tank tactics

[WorldOfForms]

This is not a debate about driver/gunner, etc. This is about trying to imagine how we will drive tanks, considering what we know about them.

The part that has me most confused is how we are going to retreat from combat, as the rear of the tank is the vulnerable part. If I engage a large number of enemies on a relatively stable frontline of combat, what happens when I need to retreat? Won't turning to escape get me killed by exposing my backside? This is assuming I'm not in a magrider.

It seems like the best tactic in a large fight will be to attempt hull-down placement or just peeking out from behind obstacles and then backing up almost as soon as you take fire. The old methods of weaving around and driving off over hills probably won't work anymore.

We'll have to play to see if this is a good or bad thing. Am I missing anything? How do you think tanks will have to position and maneuver considering the low TTK and the vulnerable rear?
