De Bellis Velitum is a set of free wargames rules from the legendary Phil Barker that features:
two small forces, each consisting of 1 to 4 sub-units, each in turn of 4 to 12 singly based 25mm figures, totalling up to 24 army points (AP) and controlled by a single player. Figures vary in cost between 6 AP and 2 AP. One figure of the most expensive mounted type or most expensive foot type present is nominated as the force’s commander and one figure of each group is nominated as its leader.
