The medieval frisians may have a medieval german ally . Nothing more is said about that ally.
Medieval Germans may have a teutonic TUG only if Imperial army . So the Frisian's ally is it an imperial army or not ? Mays the ally have that powerfull unit ?
I would have said yes. There is nothing in the wording to exclude this.
At the moment, yes.
We are reviewing all the lists to improve (restriict) the historical choices of allies. This is mostly to prevent combinations of allies that didn't occur historically, but it will also look at ally choices as well. So, did a Frisian army ever have an Imperial ally?
