Warren Berlinger is listed in the credits as playing Tony; however, all through the show, he is called Ken or Kenny Johnson.
Carl Byrd is listed in the credits as "Captain". However, both times he appears he is clearly wearing a single lapel bar indicating his rank is First Lieutenant. A Captain would be wearing a double bar insignia.
