So im REALLY far into my campaign (already got the victory condition - finishing up the scipii) and im bored of the marius legions.

So I wanted to play around with the old republican legions, but I cant seem to create them with the create_unit blah blah, the syntax is wacky and hard as I try I cant figure out what the game calls "triarii" or "hastati"

Is there a mod somewhere that lets you recruit both legions?
