Compared to World War II or the Civil War, American classrooms and newsrooms love to neglect the Vietnam War. Why? Because we don't get to say we "won," and we don't get to say we were the "good guys."
But the war with the most living American veterans was very real and consisted of horrors that few other conflicts have ever experienced.
Here are 25 photos from the Vietnam War to remind you of its horrors.
