马家军
In 1937, during the Battle of Beiping–Tianjin, the Chinese government received a telegram from Muslim General Ma Bufang of the Ma clique that he was prepared to bring the fight to the Japanese. Immediately after the Marco Polo Bridge Incident, Ma Bufang arranged for a cavalry division under the Muslim General Ma Biao to be sent east to battle the Japanese. Ethnic Turkic Salar Muslims made up the majority of the first cavalry division which was sent by Ma Bufang.
