The U.S. Army and the state National Guards operate 98 military history museums across the United States and three abroad.

The uproar led to cancellation of the exhibit. Early historians The documentation of military history begins with the confrontation between Sumer (current Iraq) and Elam (current Iran) c. 2700 BC near the modern Basra. Other prominent records in military history are the Trojan War in Homer's Iliad (though its historicity has been challenged), The Histories by Herodotus (484 BC – 425 BC) who is often called the "father of history". Next was Thucydides whose impartiality, despite being an Athenian, allowed him to take advantage of his exile to research the war from different perspectives by carefully examining documents and interviewing eyewitnesses. An approach centered on the analysis of a leader was taken by Xenophon (430 BC – 355 BC) in Anabasis, recording the expedition of Cyrus the Younger into Anatolia.
