Terrain turmoil - a question.

[krmiller]

Been wargaming 50 years now, board, miniature and pc, do not recall any system I've ever played that had any movement penalty for dead and wounded. The old Battleground games did show bodies on the ground in 3D view in hexes where losses were taken but I do not believe they changed ground conditions at all.
A case could be made for wagons and artillery blocking roads and bridges like vehicles can in some WWII tactical games. If you play with Artillery Capture Optional Rule in the ACW games and melee an artillery unit on the road it will cancel the road bonus, never meleed one on a bridge but I would presume it would do the same.
