Calculations by historian John Masson Smith, Jr. dispute conventional wisdom about the movement of this organization. Members of this organization would participate in a months-long hunt called a nerge according to the historian Ata-Malik Juvayni. This (-5[1])organization forcibly recruited people to travel ahead of it in a practice known as khashar. The most elite group within this organization was known as the (*) kheshig and it was (10[1])divided into units of 10,000 soldiers called tumen. This organization communicate orders over long (10[1])distances via 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. ■END■
