22. Genghis Khan Revolutionized Steppe Warfare
Genghis Khan further revolutionized Steppe warfare by placing his warriors in a well organized hierarchical structure, with an effective chain of command. In place of the traditional ad hoc tribal units, based on kinship groups, he created a military organization based on decimals, with a hierarchy of ranks. At the base were squads of 10 men, known as an Arbans. 10 Arbans were combined into a company of 100, known as a Zuun. 10 Zuuns made a regiment of 1000, known as a Minghan. 10 Minghans were formed into a division of 10,000, known as a Tuman. Two or more Tumans were formed into armies. A separate imperial guard of 10,000 men protected Genghis and leading Mongol figures.
