Wang defected to the Kwantung Army and persuaded the Japanese to permit him to recruit unemployed Chinese soldiers in Chahar Province to form a mercenary army with Japanese advisors. He managed to recruit approximately 6,000 men, who were trained by the Japanese and organized into four infantry brigades in Japanese-occupied northern Chahar. The troops were armed with weapons seized from Northeastern Army armories and warehouses in northern China. That force was attached another Japanese proxy army, the Inner Mongolian Army, under the overall command of Mongol Prince Teh Wang.
