Historical army compositions

[Sarcasm]

I'm with Zaknafien on this one...My standard early Republican legion is much smaller and *must* consists of:

1 General (Must have a commanding position, like being a consul [in which case he can command 2 of these])
3 Hastati
3 Principes
2 Triarii
1 Equites/Equites Extraordinari/Other allied cavalry [read greek, gallic or whatever].
2 Leves/Velites
2 units of supporting infantry (Kretans, Slingers, Lucanians, Samnites, Pedites Extraordinari, Hoplites...etc...) » These are optional

I like to have a strong RPG element in my games so I don't exploit the really deficient AI. An example of self-imposed elements are...

*Don't chase the enemy after the battle is won (so much more of the enemy survives);
*Keep Legions in forts along the Italian countryside [like an HQ's where they can muster and be refitted before a CO comes to take command] so there aren't legions running around by themselves;
*Use 3 line formation with horse alae;
*Never scout first with spies [increases chances of an ambush];
*Only command battles where family members are present [for the rest I use auto-calc];
*Never recruit more than 2 mercenaries for my armies [unless there's a Type 4 government in a city, in which case there can't be any more than 2 of my units, *or* there's a Type 3, in which case the ratio must be 1:1];
*Only advance into areas where there's an obvious need to intervene (not conquering just for the hell of it);
*Don't keep provinces that formerly belongued to an ally;
*After a campaign the legion must return home, after exchanging it with a garrison force of Rorarii or similar...
