Each of these uniforms belongs to a country in 8th century Europe, Charlemagne era. Is /r/AskHistorians able to deduce which of the armour pieces belongs to whom?
Context: It's meant to be that each piece of armour is to be a playable faction in the upcoming "Age of Charlemagne" expansion for the game "Total War: Attila", and each one will be revealed over time, but I'm more so interested if /r/AskHistorians can figure them out before the official announcements. Thus far has been the Kingdom of Charlemagne, and Kingdom of the Danes.
The helmet on the far right is the Coppergate helm from York; although I'd argue against the dating they seem to be implying, I'd say it points to the presence of the Anglo-saxons as a faction.
