Tankluver,
Consider what Hans is saying as you take a look at Konigswolf's drawing - space is gonna be an issue if you intend to show both German and US forces. Even just depicting the Germans, you're going to be cramming stuff together. Still, you might be able to get around that a bit without having to do a tremendous sized dio base.
As Konigswolf said, one advantage you might have is, if this is a winter scene, using the tracks in the snow to depict prior movements. So here is my 'vision': three vehicles: two tanks, one track, moving down a narrow forest road. Your scene will depict the start of the action: tank 1 has just been hit in the side by AT fire (if you clearly show the hit, it'll help the viewer 'see' the threat). It has slid partly off the road onto the same side the fire came from (not entirely realistic, but we'll call it artistic license), and the crew is bailing out. Meanwhile, tank 2 is swerving around behind tank 1 (again, this is unrealistic, because they should not have been that close to begin with, but work with me here), and its turret is swiveling around to bear on the target as the TC up in the open hatch is yelling and gesturing... Finally, the track is still up the road (just a couple inches) from the knocked out tank. It too has swerved towards the direction of the AT threat - the grunt on the MG maybe has already acquired the target or is in the process of opening up as the other guys are bailing out of the back. Again, have a pre-requisite NCO gesturing or pointing in the direction the AT threat is coming from.
You'll still run into the problem of cramming way too much in too small a space, but you'd want to do that anyways or you'll end up with a bunch of dead space that needs to be filled with something. It's gonna be tough, no matter how you do it, because (again, to quote Hans) depicting action, particularly extreme action - aka combat - is tricky. But, heck, it's worth a shot, right?
Like Hans said, draw up a mock-up and post it so everyone can see what you have in mind...
