For the games under development, has there been any consideration given to creation of the following:
hex-side anti-tank ditches
hex-side barbed wire?
The anti-tank ditch wouldn't be cross-able by any vehicle, while the hex-side barbed wire would be kind of like a blocked hex, but limited to only the hex-side. It would impose obvious movement penalties on foot and wheeled units, but armored units would be less affected.
Would definitely like to see these incorporated into the game. While I'm no expert, I definitely think these would not be that difficult to create, and would add something in historicity and realism to the game.
