Orc warlords are one of the best infantry units available to the Greenskins. They have a lot of health points, powerful armor and damage reduction against both ranged and melee attacks. At first they deal 60 damage, but when maxed out this value increases up to 90; The downside is the significant cost of this units. In addition, there are vulnerable to units that ignore armor or heavy fire from siege machines. However, if you must hold a narrow pass, then the warlords are they orcs you need.
