Historically accurate guides for other factions?

There's a few gamplay-oriented guides on here (particularly useful for some of the harder factions), but would anyone be interested in reading (and writing) guides similar to my own for other factions?

What this means are a completely different set of guidelines around historical house rules, not merely what's most effective. Difficulty through role-playing and limiting yourself rather than exploiting how the engine works. I mean building armies that have roughly authentic compositions, trying to expand into regions that would have been appropriate at the right time and so on.

Now I know some factions ceased to meaningfully exist (Epeiros, for example not long after the game starts), but others were around a goodly long time - certainly longer than some people play through anyway.

I'll be honest, I've written one guide and that's enough for me, so I'm not proposing to write these. I don't really know as much about any of the others as I do Rome anyway, it should be someone with the knowledge and passion to do it. But I could contribute in small ways on stuff like army composition where I know something. Others know a lot more, of course.

So who's up for it?

Well, if you can get TPC to write one about Pahlava you´ll probably be occupied for the next months just finding out what you´re supposed to do the first 5 years.

It would be nice if we can have a list of historical army composition for every faction though.

The helenic ones would be very similar, as would the celtic and nomads right?

Happy to be challenged on this, but here's my gues-timate of what a historically accurate Celtic force (Aedui, Arverni, possibly Casse) would look like.

Basically three main groupings: the Elites who are chieftains/magistrates and their bodyguards and nobles; the Warriors who are the professional fighters and mercenaries; the Levies who are the ordinary Celts called to war to serve their chief. My guess is a breakdown where half of the force is Levy, and the remaining half 1:2 Elite:Warrior. So something like a 3/7/10 split of Elite/Warrior/Levy.

So an army might look like this:
Elites
1 Brihentin (ie the general)
0-1 Heavy cavalry
0-2 Heavy infantry (Arjos, Solduros, etc)

Warriors
1-2 Light/Medium Cavalry (Curepos, Leuce Epos, etc)
1-2 Heavy infantry (Neitos, Gaesatae, etc)
2-4 Medium infantry (Botroas, Celto-Hellenic Spearmen, Milnaht, etc)
1-2 Light infantry (Kluddolon, Bagaudas, etc)

Levies
2-4 Missile (Iaosatae, Sotaroas, etc)
Remainder levy spearmen (Batacorii, Gaeroas/Gaelaiche, Lugoae, etc)

Thoughts?
