According to official Chinese Nationalist statistics, losses to the regular National Revolutionary Army totaled 3,237,000, with 1,320,000 killed 1,797,000 wounded 120,000 missing. The soldiers of the Chinese Communist Party suffered 584,267 casualties, of which 160,603 were killed, 133,197 missing, and 290,467 wounded. This would equate to a total of 3.82 million combined NRA/CCP casualties, of which 1.74 million were killed or missing. Neither total includes the considerable number of irregular guerrilla fighters sworn to regional warlords who fought the Japanese. Including them, an academic study published in the United States estimates Chinese military casualties at 6.75 million with 3.75 million killed or missing. The casualties break down as 1.5 million killed in battle, 750,000 missing in action, 1.5 million deaths due to disease and 3 million wounded.. Which suffered more casualties, soldiers of the Chinese Communist Party or the regular National Revolutionary Army?
