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.; for the evolution of Macedonian military titles, such as its command by tetrarchai officers assisted by grammateis (i.e. secretaries or clerks), see . 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.; : "The other development, which happened at the latest under Doson, was the formation and training of a special unit of peltastai separate from the phalanx. This unit operated as a form of royal guard similar in function to the earlier hypaspistai." 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.; the largest figure for elite Macedonian peltasts mentioned by ancient historians was 5,000 troops, an amount that existed in the Social War (220–217 BC). They fought alongside the phalanx pikemen, divided now into chalkaspides (bronze shield) and leukaspides (white shield) regiments..
