Urzhin Garmaev and his Northern Xing'an Security Forces of the 10th Military District also participated in the Nomonhan Incident, placed on the right flank of the Japanese 23rd Division. For his bravery in the battle, he was awarded a prize of ten thousand yen. In 1940, Garmaev was appointed commander of the 10th Army Military District of Manchukuo, and promoted to lieutenant general. His forces actively engaged in preparations for war with the Soviet Union and struggled with Soviet and Mongolian intelligence officers at the border. In December 1944, Garmaev was dismissed from his post as commander of the Military District due to the fact that he did not have the academic military education. In early 1945, Garmaev took office as the head of Xing'an Military School (陸軍興安学校) in the city of Wangyehmiao.
