– rail transport / trains : faster movement of heavier equipment…
– sea mines: to use defense tactics in shallow waters and take risks going from mine hexes….
– levels of fortification / coastal batteries
– infantry and artillery with ability to dig in….
as reaction on the previews:
-should a attacker be able to see how much Amo a defending Artillery unit has? is that realistic
-crossing a river using pontoon/bridigng equipment should slightly limit the movement of crossing units, especially armour
What a about a small percentage of battles that have a unexpected bonus due to various circumstances that you didn’t count on , which influence the outcome?
