Tanks vs Walls?

[syneris]

Walls give defense bonus except versus gunpowder units. Since tanks and modern armor are not gunpowder units but armored, do they bypass the bonus? Same for cannon and artillery because they are seige weapons. And does bombarding reduce -> eliminate the defense added by walls or is it always in effect.

 

[Gronz]

there is a slight difference between gunpowder units and gunpowder based units. the walls give no bonus against gunpowder based units, this includes all gunpowder units, armored units, air units, the cavalry/kossack as well as cannons and artillery.

MG, ironclad, transport, destroyer, carrier, submarine, battleship and ICBM also fall into this category but that doesnt matter since they either cant attack cities or dont use the regular battle mechanic.
