Did you fight in Greece as part of the Persian army?

During the wars of the Greeks with the Persians, the army of the latter was much larger than the Greek, but did not have unity, since it consisted of different peoples of the Achaemenid Empire and most of them did not understand the language of others. So, the Persians themselves and their northern neighbors, the Coppers, entered the army. Also, a large percentage were Scythians, Assyrians, Arabs, Ethiopians, some Central Asian peoples, such as Saki, Khorezmians, Parthians and many others. Since the Persians themselves did not possess a fleet, the Phoenicians, Egyptians, etc., ruled the ships at sea.
