Men of Bronze is a good series of essays on Greek Hoplite Warfare from various scholars in the field. Another good one is volume one of the Cambridge history of Greek and Roman Warfare

I would recommend Greek Warfare: Myths and Realities by Hans Van Wees (2004). It is especially concerned with development of the hoplite and its tactics and has a large and very interesting section about the works of Homer and how far they can be trusted to give any evidence at all for the way in which early hoplite armies would have engaged in battle, with reference to how modern tribesmen in Papua New Guinea use similar styles of lyricism to describe their battles.

Of course much of this book therefore makes reference to preclassical Archaic phalanxes it does also have sections on the Classical phalanx.

I just finished Tides Of War by Pressfield. Excellent.

Alexander the Great would be the obvious candidate for the most accomplished military leader from Greater Greece pre-Roman conquest.

He was the only one who conquered most of the known world, winning many battles against superior odds in the process.

I always enjoy the Landmark Thucydides, which is about the Peloponnesian Wars.
