Roman Legion composition?

[Lanceari]

Polybius mentions only that the different classes (H, P, and T) are divided into 10 maniples; he says nothing about the legion as a whole being divided this way. This is most likely an attempt to find a (non-existent) connection between Polybian and Marian organization below the level of the legion and above that of the century.

Polybius uses the term cohort in reference to army detachments in Spain during the Second Punic War. See Adrian Goldworty's The Complete Roman Army (p. 87 et seq.)

...so term existed and stood for a detachement "below the level of the legion and above that of the century."

My interpretation on the Passage you cite is that Polybius main focus was on the Roman officer class. The modern audience may be more interested in the organization of the army. But, this may not have been the preferred point of reference in antiquity. It seems, back then people paid more attention to "who is who." Since cohorts had no formal officer in charge, Polybius probably saw no need to include them in the passage you cite.

That is very interesting insight into the command structure of the legions. How would one simulate this in the game?

I think EB is just great as it stands.

I would not refer to the Legionary units as "cohorts". I would simply call them legionaries. This would be consistent with EB's treatment of other units in the game (e.g. a "classical hoplite" unit is simply a "classical hoplite").

I do not know how to replicate the Military Tribunes within the RTW framework...
