Factors that helped Genghis Khan achieve results that have never happened in world history.

The presence of the Khitan tribes in the army had a huge impact on the combat capability of the army. They were very well-armed mounted warriors. They had armor and helmets. The army was very competently divided into divisions. Representatives of one or related tribes served in dozens and hundreds. Different nations served in the larger ones. Espionage and intimidation tactics were widely used. Mobility and the famous bow played an important role. The betrayal and transition of the Russian princes to the side of the Horde simplified the task. The Genghisid army was very numerous. They used light and heavy cavalry, siege equipment. It was the most modern and armed army at the time.
