An Army Open to Talents
[King Philip] had carried through a social revolution among the Macedonian military class…. The old nobility were laid under an obligation of regular military service; to it a new nobility of military adventurers was added, recruited and promoted on the basis of professional excellence. The result was an army ‘open to talents’, in which the king’s new and old followers competed for position in demonstrations of loyalty and self-disregard.
