 The Chinese armies allied to Japan had only 78,000 people in 1938, but had grown to around 649,640 men by 1943, and reached a maximum strength of 900,000 troops before the end of the war.Almost all of them belonged to Manchukuo, Provisional Government of the Republic of China (Beijing), Reformed Government of the Republic of China (Nanking) and the later Nanking Nationalist Government (Wang Jingwei regime).These collaborator troops were mainly assigned to garrison and logistics duties in their own territories, and were not fielded in combat very often because of low morale and Japanese distrust.
