What Greek military hero do you admire most?

[Eleatic Guest]

Pericles, for his (mostly) astute management of the Peloponesean war, until he succumbed to the plague!

As far as I remember, the Athenians burnt up the larger part of their immense treasury in the few years during which Pericles coordinated their war effort, so costly was his conduct of war. His way of war would have bankrupted Athens many times before they would have won.

I agree with Christopher that Iphicrates' achievement is largely overlooked. He was largely responsible for the introduction of lighter troops into Greek warfare which further softened up Sparta's military hegemony and made Greek warfare at large more flexible and mobile, both developments which contributed to Alexander's successes in the vast eastern theatre.
