Thanks for posting.
Your post mentioned “Athenian hoplite formation” so I had to look that up. That led to learning about linothorax armor and a side trip to a graduate student and his professor who actually made some not long ago and tested it. Then I was on to “phalanx” formations and how that originated and how it worked in practice.
That was a nice 30 minutes!
Glad I could help. :^) The ancients really knew how to bust **** up.
