安提柯三世
The most elite, veteran Antigonid-period Macedonian infantry from at least the time of Antigonus III Doson 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. The premier guard infantry unit of the regular army, they are not to be confused with the skirmisher troops of the same name, denoted by their shield, the "pelte". Among the peltasts, roughly 2,000 men were selected to serve in the elite "agema" vanguard, with other peltasts numbering roughly 3,000. The amount of peltasts varied over time, perhaps never more than 5,000 men (the largest figure mentioned by ancient historians, an amount that existed in the Social War of 219 BC). They fought alongside the phalanx pikemen, divided now into "chalkaspides" 'bronze shield' and "leukaspides" 'white shield' regiments, up until the very end of the kingdom in 168 BC.
