Antigonus III Doson
Thanks to contemporary inscriptions from Amphipolis and Greia dated 218 and 181BC, respectively, historians have been able to partially piece together the organization of the Antigonid army under PhilipV. From at least the time of Antigonus III Doson, the most elite Antigonid-period infantry were the peltasts, lighter and more maneuverable soldiers wielding "peltai" javelins, swords, and a smaller bronze shield than Macedonian phalanx pikemen, although they sometimes served in that capacity. Among the peltasts, roughly 2,000 men were selected to serve in the elite "agema" vanguard, with other peltasts numbering roughly 3,000. The number of peltasts varied over time, perhaps never more than 5,000 men. They fought alongside the phalanx pikemen, divided now into "chalkaspides" (bronze shield) and "leukaspides" (white shield) regiments.
