[DRG]

I have been working on something just like that and digging around the net for more info

EDIT

I had what was shaping up to be an interesting variant with hills more like reality and I got it done to the point of running a playtest and it started with the message that "USMC Engineers clear dragons teeth" which is a really nifty trick given they were in LVT's over half a km away from the nearest DT.......I took them out... repurchased them, reloaded them and started the game....same message...then the screen greyed out and locked up so that's a "delete me!!" dead end.

Don Lazov will attest to the joy of trying to massage an old scenario. It can be quite an adventure but once they start going sour there is only one solution. It's too bad. it was really starting to get interesting.
