Miltiades also convinced the other generals of the necessity of not using the customary tactics of using hoplites arrayed in an evenly distributed phalanx armed with shields and , tactics otherwise not deviated from for 100 years, until the time of Epaminondas. Miltiades feared the cavalry of the Persians attacking the flanks, and asked for more hoplites to be stationed there than in the centre. He ordered the two tribes in the centre, the Leontis tribe led by Themistocles and the Antiochis tribe led by Aristides, to be arrayed to a depth of four ranks while the rest of the tribes, on their flanks, were arrayed in eight ranks. Miltiades also had his men march to the end of the Persian archer range, called the "beaten zone", then break out in a run straight at the Persian army.
