During the seven and a half months the US fought in WWI, 116,516 American soldiers were killed, almost 9% of all US war deaths and more deaths than in all US wars combined since, with the exception of WWII. During WWI another 204,002 soldiers were wounded. As three million men were drafted, almost 4% of draftees were killed and almost 7% wounded. For all those who have served, thank you!
