As a result, a number of Parmenion's relatives were placed by Alexander in key positions in the Macedonian army. His youngest son Nikanor became commander of the infantry regiment known as the Shield bearers, his son-in-law Coenus commanded a phalanx battalion while another relative named Nicanor became admiral of the navy made up of Macedonia's Greek allies. Parmenion's friend Amyntas and his brother Asander were placed in key positions. Parmenion's oldest son Philotas was made commander of the Companion cavalry, a unit of 1800 horsemen that was Macedonia's most effective weapon in its battles. Parmenion became Alexander's second in command, the same position he had held under Philip.
