The ending is pure Hollywood. Interestingly, it turns out one of his brothers was still alive, so the whole mission was for not! At lest the Normandy landing was very realistic according to men I knew that landed that day.It may seem like a tedious Hollywoodism, but it was based on a real incident that was told to writer Robert Rodat by a World War 2 vet when he was doing research for the screenplay.
