"Bows and Spears in Achaemenid Persia" by James White

I recently came across James White's 2019 dissertation for UC Santa Barbara at eScholarship.  It is, as the name indicates, an overview of what's known and indicated from archaeological, artistic and literary sources about Achaemenid bows and spears.  I haven't read the whole thing yet, but it appears to be very informative; at the very least it's a good index of sources.
