IIRC, Total War: Rome has "screeching women" as a unit for the Celts, the Germans and the British tribes...

I remember reading something about the siege of Alesia but i think it went the other way - the women were sacrificed...

So I would say "of course, there were some women fighting in barbarian armies and probably forever, everywhere as soon as wars required real mobilisation and/or involved sieges". The points are two-fold, though. They were a minority. And the societies they came from were still barbarically patriarchal - if not to the Roman or Greek extent.

It still doesn't say much about whether we should let women join modern armies combat units per se and how to address the problems that might arise from that fact.
