Green Standard Army
The Green Standard Army (; Manchu: "niowanggiyan turun i kūwaran") was the name of a category of military units under the control of Qing dynasty in China. It was made up mostly of ethnic Han soldiers and operated concurrently with the Manchu-Mongol-Han Eight Banner armies. In areas with a high concentration of Hui people, Muslims served as soldiers in the Green Standard Army. After the Qing consolidated control over China, the Green Standard Army was primarily used as a police force.
