Jakal72,
the idea sounds good, but maybe you could make a skets so that whe can see the intended lay-out and responf to that?
One small thought, the grenades that the germans will trow are not that effective against a tank (even a Sherman), they can cause damage, and whith a lucky trow even damage a track, but for your dio, you will get a lot of responses of that.
You could increase the impact of the stickgrenade by attaching them to a jerrycan (firebomb) or trow in a panzerfaust
