Although Ma Chao was well aware that the combat power of the Qiang Cavalry was virtually equivalent to nonsense, in the Central Plains, they mostly could only contend against infantry, and might not even be able to handle elite infantry.
One must know that during the suppression of the Xiliang Qiang Rebellion, the Elite Soldiers of Danyang coordinated with the Xiliang Iron Cavalry to crush the Qiang Cavalry. Although the physical quality of the Qiang was not inferior to the Han, in this era, once the numbers exceeded a hundred, it was nearly axiomatic that foreign clans were difficult to match the Han Court's military in a frontal assault—even the foreign clans themselves acknowledged this reality.
Well, regardless of how ludicrous the combat power of the Qiang Cavalry was, at least in support and in favorable battles, they were quite decent, as the numbers were there. A large group charging ahead still projected a formidable momentum.
