Listen to Dan Harlan’s Hardcore History titled King of Kings. It predates Islam and covers the history of the near east up to Alexander the Great. However, it provides an extensive explanation of the geographic, and subsequent cultural and tactical differences between the “Asian” (mostly Persian) and European militaries. The geography doesn’t change much between antiquity and the crusades, so those differences carry through and are still applicable.
