 These forces defeated the last major hoplite army, at the Battle of Chaeronea (338 BC), after which Athens and its allies joined the Macedonian empire.While Alexander's army mainly fielded "Pezhetairoi" (= Foot Companions) as his main force, his army also included some classic hoplites, either provided by the League of Corinth or from hired mercenaries.Beside these units, the Macedonians also used the so-called "Hypaspists", an elite force of units possibly originally fighting as hoplites and used to guard the exposed right wing of Alexander's phalanx.
