This small, but tough Roman army follows the parameters detailed on the Basic Impetus page of Dadi & Pombo’s web site. At present, I have completed two medium cavalry, four heavy foot and two skirmish elements, which is the standard force for these rules. Units stats, special weapons and other list options can be viewed for free on the Basic Impetus web page under the army list sub section entitled Rome and the Mediterranean.
Based to match my Carthaginian and Numidian armies on 3mm thick laser cut plywood all units share a common frontage of 120mm. Only the base depth varies depending on the unit type, 80mm for cavalry, 60mm for infantry and 40mm for skirmishers.
Figure wise I chose to build the entire army from Aventine miniatures excellent Republic Roman range. The little big man shield transfers and steel javelins were also procured from Aventine miniatures at the same time.
