Most of genghis Khan's life has been spent on the battlefield. Nomads have always been brave and warlike, but they are not good at protecting the country. Since Genghis Khan was so heroic, what if the army did not have enough food supplies?

Through the understanding of history, we can know that Genghis Khan's method was to take advantage of the conditions of nomadic peoples born on horseback, they would bring their own cattle and sheep in the long course of conquest, and on the way these livestock would be used as food, and these livestock would advance faster than grain and grass carts. Another point is the difference between the nomadic and Han Chinese, who can use the principle of horses on the grassland to match each soldier with more than two horses. This allows you to take turns riding horses, and you can also ensure the speed of the march, giving the horses some opportunities to buffer their physical strength.
But in addition to this method, the wisdom of the nomads is very powerful. They also have a way to get food, that is, every time they take a city, they will grab what is in it, just like a locust invasion, because their personalities are very barbaric, and this situation is tacitly approved by their superiors, so they basically do not have to consider the food and clothing of the soldiers.
This also happened during World War II, when the Japanese army followed Genghis Khan's example in order to fight better. But Genghis Khan's prestige has spread to the entire Eurasian continent and even Europe and the United States, and how can the Japanese army be compared with Genghis Khan? The U.S. military simply does not take the Japanese army seriously. At that time, the Japanese army was planning to cross no man's land, and nearly 100,000 troops had to watch out whether the livestock escaped. Soon they were spotted by the British in India and sent several bombers directly to the Japanese. In the end, the Japanese army was so miserable that nothing was grabbed, and the animals fled in fright, and this time the war lost tens of thousands of people in vain.
