Major Units have almost the same Information Window. However, there are some notable changes. In place of a Load value, you have a Combat Bonus. In place of a commodity chart you have a spell list. In place of a Unit Carry, you have an Age indicator. Also Major Units attack equally into all types of terrain. There are a few different buttons as well.
