Roman Republican Legionaires
Early Polybian-era or late Camilan Romans. The Polybian army's operations during its existence can be divided into 3 broad phases. (1) The struggle for hegemony over Italy, especially against the Samnite League (338-264 B.C); (2) the struggle with Carthage for hegemony in the western Mediterranean Sea (264-201 BC); and the struggle against the Hellenistic monarchies for control of the eastern Mediterranean (200-91 BC).

Under Caesar Augustus, the Auxilia was made up of about 250 cohort size (500 men) regiments, or a total of 125,000 men. Auxilia contained heavy infantry equipped similarly to legionaries; and almost all the army's cavalry (both armored & light), and archers and slingers. Under Severus, the total number of regiments increased to about 400 (or 250,000 men).
