Although Wilson found it necessary to clarify service roles and missions, he did not press for extensive further unification of the armed forces. He established in February 1956 an office of special assistant to the Secretary of Defense for guided missiles but made few other changes after implementation of Reorganization Plan No. 6 in 1953. When asked in 1957 about persistent demands for further unification, Wilson responded, "It's an oversimplification in the false hope that you could thus wash out the problems if you put the people all in the same uniform and that then they wouldn't disagree over what should be done. Of course, they would."
