三藩之乱
During the Revolt of the Three Feudatories, Manchu Generals and Bannermen were initially put to shame by the better performance of the Han Chinese Green Standard Army, which was noted by the Kangxi Emperor, leading him to task generals Sun Sike, Wang Jinbao, and Zhao Liangdong with leading Green Standard Soldiers to put down the rebellion. The Qing considered the Han Chinese to be superior fighters, so used the Green Standard Army, rather than Bannermen, as the main force in defeating the rebels.
