Fury of the Northmen mod have a load of information... Maybee you can get some info there or maybee join them... 'cause your units is great!
Thank you, however I don't think I can join them as they mod MTW. I don't even have MTW anymore, and the new 3D engine of RTW prevents me from even thinking about going back to MTW
What is needed is a "Viking mod" for RTW.
