"Only with the introduction of trucks and tanks in World War I did horses finally become supplanted as the main assault vehicle and means of fast transport in war. Arabian and Bactrian camels played a similar military role within their geographic range," shared Jared Diamond, in his seminal 1997 book entitled Guns, Germs, and Steel: The Fates of Human Societies. In all these examples, people with domestic horses or camels (later with trucks and tanks), or with improved means of using them, enjoyed an enormous military advantage over those without them.
