re: Movie Easter eggs and plot points that blow your mind

Was watching part of First Blood last night, and there is a scene where they think Rambo is dead and the Sheriff comes back to his office. When he goes to sit at his desk, behind him is a plaque with three medals - The Silver Star, Purple Heart, and Army Distinguished Cross. Supposedly this was referenced in the book, but I never noticed it in the 500+ times I've seen this movie, until last night.
