SPQR: Macedonian Pezhetairoi

The Pezhetairoi (foot companions) built upon the success of the Greek phalanx – and improved it. Deeper formations were used, along with the sarissa, a pike much longer than the spears used by the city states. Whereas the phalanx was the mainstay of Greek armies, under Alexander they were used to pin enemy units and hold them until they could be smashed by the Companion Cavalry.
