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
