 During the Wars of the Diadochi, the Macedonian army, as developed by Alexander and Philip II, gradually adopted new units and tactics, further developing Macedonian warfare and improving on the tactics used in the Classical era.The armies of the Diadochi bear few differences from that of Alexander, but during the era of the Epigonoi (Ἐπίγονοι, "Successors"), the differences were obvious, favoring numbers over quality and weight over maneuverability.The limited availability of Greek conscripts in the east led to an increasing dependence on mercenary forces, whereas in the west, Hellenistic armies were continuously involved in wars, which soon exhausted local manpower, paving the way for Roman supremacy.
