Rogue Agent

"Sergei: "I'm sorry about the unfortunate incident. It was excessive, and more to the point it was foolish. Mikhi did it without consulting me."

Gregor: "He turned rogue and can't be controlled? Is that it?""

- Ronin

A member of a government intelligence agency or military unit who starts operating on his own authority. Often this is merely a cover for activities the government in question would denounce if anything went wrong. If more than one person is involved, it will be described as a 'renegade operation' or 'rogue elephant'.

For writers this is a good way to have a villain with all the skills and knowledge of the heroes, should they also be spooks or special forces soldiers. Also useful if you're Backed by the Pentagon, as you're not disparaging the organisation as a whole, just a 'bad apple'. Likewise, Irish terrorists are often described as being from rogue factions to avoid having to deal with The Irish Question.

See Renegade Russian and Terrorists Without a Cause for specific examples of this trope.

Film

 * A major theme of Ronin where the characters are former Cold War spies and special forces operatives working as mercenaries, . Likewise, the terrorist Seamus is denounced by Sinn Fein as a 'rogue breakaway operative' after he fails to get his hands on the mysterious suitcase.
 * John Woo's Broken Arrow: USAF pilot Major Vic "Deak" Deakins (John Travolta) helps steal an atomic bomb. To further separate him in the audience's minds, the military insisted his character wear civilian clothes once the theft had taken place.
 * The Bourne Series: The employers of the main character think he's done this, but he's actually suffering from Easy Amnesia.
 * In The Matrix Reloaded and The Matrix Revolutions, Agent Smith drops his "agent" position and simply becomes "Smith" when he.
 * Under Siege: William Strannix (Tommy Lee Jones) is a renegade/rogue former CIA agent, as is Travis Dane in the sequel. The latter was merely fired, but as the former turned traitor they tried (unsuccessfully of course) to have him killed. Both are murderously unhappy at their respective plights.

Literature
""Are you talking about a penetration?"
 * In the X Wing Series, Rogue Squadron left the New Republic to pursue a foe that the New Republic couldn't touch without alienating their allies. Notably, at this point in time there were a number of anti-Imperial groups who were only loosely affiliated with the Rebel Alliance/New Republic, and the Rogues were able to set themselves up as one of them, though there were rumors that Rogue Leader, Wedge Antilles, was setting himself up as a warlord. When they succeeded in helping a faction on that planet to overthrow Isard, they were retroactively sanctioned, and that whole thing where the New Republic's best fighter squadron publicly resigned was brushed under the rug.
 * The protagonists of the Eisenhorn and Ravenor series become Rogue Agents in, respectively, Hereticus and Ravenor: Rogue. It's necessary under the circumstances, but Eisenhorn kills at least one man whose only crime is trying to stop him.
 * Flight of the Intruder: A protagonist example, with the two main characters going on a renegade bombing mission to hit Communist Party Headquarters.
 * 19 by Roger Hall: A peculiar variant was the title organization "19". Most of the members were still part of various U.S. intelligence agencies, but secretly working for a retired OSS officer (who'd been their commander during the war) to do the work of American counterintelligence more effectively than the official agencies could. Its existence was unproven, its makeup unknown, and although it was evidently working to protect the U.S., many U.S. security types were determined to break it.

"Literally speaking, yes. But not by the opposition. If 19 exists, it's on our side. Although some of the things it's done, if it did them, were enough to give me the inside sweats.""

Live Action TV
"Cordelia: What's a rogue demon?"
 * Jack Bauer in every season of 24 qualifies, though he remains on the side of good the whole time. Nina Myers, Stephen Saunders, Christopher Henderson and are all villainous examples.
 * NCIS has Mossad agents Ari Hassari and Michael Rivkin.
 * Stargate SG-1: Rogue NID agents becomes the standard human villains. Also very occasionally played by SG-1 itself -- notably at the end of Season 1, when the Stargate program is being shut down just as Daniel has knowledge from an alternate timeline that Goa'ould are about to devastate Earth. Since he turns out to be right and they stop this from happening in the main timeline, they're forgiven and everything goes back to normal.
 * Farscape. The Peacekeeper Crais goes rogue to hunt down John Crichton whom he blames for the death of his brother.
 * In one episode of The Fixer, John Mercer is ordered to kill his predecessor, who has started to pick his own targets instead of those selected by the mysterious unit he works for. There's also the SAS man who (under orders) used drug money to finance his anti-Taliban operation, who decided to go into business for himself.
 * Doctor Who. The Doctor is used in this role in his 3rd and 4th incarnations, as a deniable agent for when the Time Lords decide to break their own rules of non-intervention. The Doctor is not happy about it, as he'd rather be a genuine rogue.
 * Faith in Buffy the Vampire Slayer. This causes problems for the Watcher's Council as until she dies the line of Slayers can't continue; they do their best to rectify the situation in Angel.
 * Wesley tries to reinvent himself as a rogue demon hunter after being fired. Nobody really buys it (at least not initially).


 * This is constant issue in Series\Nikita.

 * A number of Division undercover agents decided to go rogue and stopped obeying orders from Division.

 * For the majority of Alpha Protocol, Mike Thorton is a rogue agent when he learns that
 * Of the people you meet during the game, Conrad Marburg is an ex-rogue agent turned civilian contractor (and also something of Mike's Evil Counterpart). And then there's Steven Heck, who may be a rogue agent. He may also be a non-rogue agent for a particularly deep-cover (and indiscriminate) part of the CIA. Or he may be completely bugfuck insane and thinks he is either of the above.
 * Mass Effect 1 has Saren, the Council's most famous Spectre, going rogue
