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, (10[1])which was divided into units of 10,000 (-5[1])called tumen. (10[1])This organization communicated orders (10[1])over long distances via the yam system. (-5[1])One campaign by this organization was foiled by the kamikaze wind, though it earlier engaged in successful campaigns against the Khwarezmian (10[1])Empire and Song China. For 10 points, name this military force founded by Genghis Khan. ■END■ (10[1])
