|Chiefs of Starfleet Operations|
|James T. Kirk • Bob • Leyton|
Bob was played by Star Trek film writer and producer Harve Bennett wearing a Starfleet uniform with a fleet admiral's rank insignia. He was referred to solely as "Bob" by Kirk, referenced in the script as "Commander" (which in itself could be either "commander, Starfleet" or "commander in chief"), and listed as "Starfleet Chief of Staff" in the end credits.
The name "Robert Bennett" was adopted by the Star Trek Encyclopedia and was later adopted by StarTrek.com's article on him, as well as non-canon novels written by William Shatner (with Judith and Garfield Reeves-Stevens). In J.M. Dillard's novelization of Star Trek V the character was named "Bob Catfisch" and had been, at one point, Kirk's subordinate at Starfleet Command.
