In the book History of Ancient Greece, the author Nathaniel Harris describes Alexander's expedition to Asia as a ‘Greco-Macedonian expedition'. Janko points out that it is not correct to give the Greeks such prominence with the Macedonians as the Greeks were a minority in the army compared to the Macedonians, and the expedition also had many Thracians, Illyrians and even some Jews. And on the other side, tens of thousands of Greeks fought for the Persian army against the Macedonians but Harris does not call this a Greco-Persian army.
