Help Can Tanks Reverse

[Gordons HQ]

At the moment I'm playing a campaign game of SPWaW version 8.4 I'm playing the Germans at Kursk in 1943. It's just that the the Russians really greatly outnumber the German side in everything including the tanks. The visibility range for the game is very low about 6 hexes, so the long range firepower of the German tanks is out of the question
Thinking I would use some good tactics here I thought it might be a good idea to fight a delaying action with infantry and tanks. The idea was as their tanks came into view I would fire a couple of rounds and then reverse out of sight and wait for them to appear again. The same with my infantry mixed amongst the tanks and of course putting down an artillery barrage as we retreated. The mission was a delaying action as assigned by the computer.
Imagine my horror as after firing off a shot or two, when trying to retire my tanks turned around first before moving and showed their rear to the enemy.
They became such easy prey for the AI they were shot up so easily they might just as well have stayed there and tried to slug it out before first being shot to pieces.
The Question I have is there anyway I've missed in the manual where you can reverse tanks and vehicles as opposed to the turning around in this fashion. I would appreciate any help on the matter, although it might be too late for this particular campaign as I'm going down real fast.

Cheers,
Gordon
