Both have numbers. So I could be the First Battalion, 235th Infantry Brigade, 3rd Infantry Division. There are several levels of numbering, but so far we have been choosing just one number for the sake of simplicity. I know there was talk at one point of grouping players into specific divisions once we get a larger playerbase and the warmap.
think ing about it that is all ready done, all the inf players are the infantry divison, and they each have their own battilions when at T4
