3rd vs 4th edition

[Greyfox]

I agree that there are a number of improvements; however, on thing that has not been adressed. There are no direct or anti-tank penalties for someone moving accross a bridge or ford; through a wadi or a mountain defile; nor along a sunken track or riverbed. The fact that there is not a choke point die role modifier for those able to fire along a constricted avenue of approach is surprising. Don't know about you, but that is exactly the type of terraim I like to lay in my ambushes or establish my battle positions. Imagine how that could change the dynamics of a scenario like "Bicycle Races" in White Eagles or increase the effectiveness of mountain troops in alpine or rough terrain.
