In the American involvement in the Vietnam war from 1964-1975, it is generally accepted that of the American military personnel deployed, about 58,200 died, another 153,000 casualties were hospitalized with injuries, and of those, about 100,000 were permanently disabled or disfigured. The number of survivors physically disabled was enormously higher than in the second world war and in the war against Korea.
One piece of info about American casualties that's not often reported is that after the war ended as many former soldiers committed suicide as were killed in battle.
