Description acceptable. Calculations by historian John Masson Smith, Jr. dispute conventional wisdom about the movement of this organization. The hatanga was a garment wore by members of this organization. Members of this organization would participate in a monthslong hunt called a nerge according to the historian Ata-Malik Juvayni. The hashar was a practice by which people were (*) forced to travel ahead of this organization. The kheshig was the most elite group within this organization, which was divided into units (-5[1])of 10,000 called tumen. This organization communicated orders over long distances via (-5[1])the yam system. One campaign by this organization was foiled by the kamikaze wind, though it earlier engaged in successful campaigns against the Khwarezmian Empire and Song China. For 10 points, name this military force founded by Genghis Khan. (10[2])■END■
