The Military Intelligence branch insignia (a rose and sunburst superimposed over a dagger) shown on Orin Newton's World War II uniform jacket was not created until 1962, 17 years after the end of that war. Prior to that, the Military Intelligence branch insignia was a gold shield with a Sphinx on it.
