The American forces, widely called “doughboys”, were rather diverse and considered the key factor that brought about the turning point leading to the Allied victory in WW1. There were almost 4 million U.S. soldiers and several thousand nurses by the end of the war, 20% of whom were born outside America. Black soldiers, who made up around 13% of the total U.S. fighting force, served in segregated units and performed menial tasks. Native Americans, however, served alongside whites and were assigned dangerous duties thanks to being stereotyped as “warriors”. In total, 50,000 died in action and around 63,000 died from disease during the war.
