First Non-Playable Faction Units in Screenshots?

[GideonAI]

Hey guys, I just noticed that the Athens and Sparta screens show off some units the Athenians and Spartans are fighting on the sides that I don't recognize as belonging to any particular faction. Perhaps some of you can tell what kind of units they are?
Athens:http://wiki.totalwar.com/images/c/ca/Athens.png (The horseman on the right has a boar on his helmet)
Sparta:http://wiki.totalwar.com/images/d/d3/Sparta.png (These men look suspiciously like Suebi tribesmen)

My best guess is that they are Dacians or Thracians, but I'm no expert.

The warriors depicted on the Athens screenshot are certainly Celts.
They have Celtic style helmets (some with boars), the leather armor looks celtic and the shields as well.
Those warriors who are fighting against the Spartans are surely Germanics.

Yeah, I did notice some similarities with the celtic armour Jack posted a while back and the leather armour of the horsemen in the picture.
Fascinating that they decided to picture the Spartans fighting Germanics though. You'd have expected maybe Persians just for recognition's sake.

They might be Arverni and Suebi.
