I am really concerned about the tanks along the reverse slope and should the attacking player be given subtle clues on the map of the reverse slope. In the game, if the size of the elevation is equal to or greater than the vehicle size, the vehicle is neither hull down nor turret down, but hidden. If the player does not notice the slight elevation, he may move his vehicle along at say 7 to 11 mph, once he moves over the elevated hex, the tanks in the reverse slope will light him up. If the player has defending units say ATGMs and AFVs on the counter slope, case close, it is a kill.
The AFVs along the reverse slope should be hidden. Otherwise, an opposing scouting unit or slow moving AFV may spot the turret and engage it with tank fires and missiles.
