It's not a question of dust.
I just want my tanks to use up their HE load before the end of the battle.
I am not using 'area fire'...I am directing them, each turn, to shoot 'main gun HE' at infantry...They will often shoot one round of HE for that turn and then they revert back to machine guns.
Again, I finish the battle with about 50% of my HE still unused...Any tips?
