Bob

From Memory Alpha, the free Star Trek reference

You may also be looking for a "bob", the slang term for a shilling.

Bob was a 23rd century Starfleet officer who served as an admiral of Starfleet Operations during the 2280s.

In 2287, he ordered the USS Enterprise-A to planet Nimbus III to rescue three ambassadors who had been taken hostage by the Vulcan renegade, Sybok. (Star Trek V: The Final Frontier)

[edit] Background

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).
