This series gave Dizzy Flores an actual name. In the novel, Flores was a male, and a very minor character. He was referred to as "Dizzy" several times during his one scene, and it is unclear as to whether that was his name or a nickname. In the 1997 Starship Troopers movie, he was turned into a female love interest, though it is still never clearly stated as to whether or not "Dizzy" is her legal name. On the Roughnecks series, one of the writers just decided to give Isabel as the legal first name, hence "Isabel 'Dizzy' Flores."
