This supplement for Hail Caesar contains over 120 army lists covering the biblical and classical periods, from the first civilizations of the Near East to the height of the Roman Empire; to the forces of Late Antiquity, the Dark Ages and Early Medieval periods, from the "crisis" of the turbulent mid-third century to the Mongol invasion of the thirteenth. Previously available in two separate books, these lists have now been compiled into a single volume that spans over three thousand years of human history. Each list provides a guide to army composition, suggest game values for troops, and points values for the different units.

This supplement also includes copious notes on the methods of composition to assist players who wish to create their own armies, together with a breakdown of the system used to work out points values.
