Melee Siege Attacker

Melee siege attackers can choose to directly attack a structure. This attack uses the melee attack and damage values of the unit. The AC to hit a structure is 10, and hits are not subject to glancing blows or critical hits. On a hit, damage is automatically dealt to the structure. Melee siege attacks do not damage units occupying a structure struck by this attack (though they are still subject to the consequences of occupying a structure when it is destroyed, see Battlefield Features for more details).
