@ tmh47, and THEMIK, concerning your comments on units names, I must beg to differ on your position, and I am of the opinion that you really do not know what you are talking about.
The names used are, besides generic names used in modern science, mostly contemporary military names I've found in different sources, and which have then been translated into Old Norse by Aule_the_Creator.

It sounds as if you think the mercenaries are the real Scandinavian roster, which it isn't, and please do be mindful in the future to play for more than a few minutes before making assumptive posts. But if you have anything real constructive to add, please do so, finding correct unit names are at most times guess-work, as WB troop trees are very artificial ( at best ) compared to historical Scandinavian military organization.
