Ok, Made a little progress.
I think I've got all the German units up. If someone who is familiar with the Holy Roman Faction could check it out I'd sure appreciate it.
what I need looked at is the buildings and events and how they effect unit recruitment. I'm sure anyone whose looked at the data files will agree that the export_descr_buildings.txt file is extremely difficult to figure out. Just make sure I've got right.
