Ancient Greek warfare of the phalanx to its logical completion, arming his 'phalangites' (for they were assuredly not hoplites) with a fearsome pike, the 'sarissa'. Much more lightly armored, the Macedonian phalanx was not so much a shield-wall as a spear-wall. The Macedonian phalanx was a supreme defensive formation, but was not intended to be decisive offensively; instead, it was used to pin down the enemy infantry, whilst more mobile forces (such as cavalry) outflanked them. This 'combined arms' approach was furthered by the extensive use of skirmishers, such as peltasts. Tactically, Phillip absorbed the lessons of centuries of warfare in Greece. He
Spartan army peltasts became a much more common sight on the Greek battlefield and themselves became more heavily armed. In response to Iphicrates' victory over Sparta in 392 BC, Spartan hoplites started abandoning body armour and eventually wore almost no armour apart from a shield, leg greaves, bracelets, helmet and a robe. In later periods Spartans did start to readopt armour, but on a much lesser scale than during the Archaic period. Finally during 227 BC, Cleomenes' reforms introduced updated equipment to Sparta, including the Macedonian "sarissa" (pike). However pike-men armed with the "sarissa" never outnumbered troops equipped in the hoplite style.
