Historically Accurate, Well-Balanced Romani Army Based Upon Polybius and Vegetius

[Marie Louise von Preussen]

So I've made two schemes:

ROMANI POLYBIAN ARMY



And the part that wasn't included in the end said "... armies".

ROMANI POST-MARIAN ARMY

[Dooz]

Nice. And here's my Camillian contribution to round out the Romans.

[Humbug_Total]

My take is on pre-Marian armies a bit different, but close to Dooz´ roster. I center it around the idea that a consular army is usually two legions, while a praetorian army is one legion with half of the units coming being allied contingents.

A single legion is one each of:
Roman skirmishers (Leves or Velites) & Allied skirmishers
Hastati & allied lighter infantry
Princeps & allied heavier infantry
Triarii
Equites + FM

For the allied units I use either Socii (sometimes for both Hastati and Princeps line) or other units from the local recruitment pool to reflect the local origin of the legion. When I combine two legions for a consular army, I use only one equites and one locally recruited cavalry unit for the allies. This leaves room for an additional FM (young ones as military tribunes), siege equipment if needed, or extraordinary if the army is commanded by a currently serving consul.
