When siege rules are in effect, the attacking foot units have scaling ladders and other siege equipment. NOTE: All city walls scenarios in this core game are considered impassable terrain. |
| Battle | No battle possible unless siege rules are in effect for the scenario. |
| Line of Sight |
A city wall hex blocks Line of Sight to units behind the city wall hex and vice versa. |
