苏武
In 123 BC, Emperor Wu sent Wei Qing from Dingxiang () to engage the invading Xiongnu, and appointed the 18-year-old Huo Qubing to serve as the Captain of Piaoyao () under his uncle, seeing real combat for the first time. Although Wei Qing was able to kill or capture more than 10,000 Xiongnu soldiers, part of his vanguard forces, a 3,000-strong regiment commanded by generals Su Jian (蘇建, father of the Han diplomat and statesman, Su Wu) and Zhao Xin (趙信, a surrendered Xiongnu prince) was outnumbered and annihilated after encountering the Xiongnu force led by Yizhixie Chanyu (). Zhao Xin defected on the field with his 800 ethnic Xiongnu subordinates, while Su Jian escaped after losing all his men in the desperate fighting. Due to the loss of this detachment, Wei Qing's troops did not earn any promotion, but Huo Qubing distinguished himself by leading a long-distance search-and-destroy mission with 800 light cavalrymen, killing the Chanyu's grandfather and over 2,000 enemy troops, as well as capturing numerous Xiongnu nobles. A very impressed Emperor Wu then made Huo Qubing the Marquess of Champion () with a march of 2,500 households.
