"There's a group of guys down here, way out on the hairy edge. They did covert stuff, and then... they went rogue. Went renegade, dropped off the face of the Earth, disappeared into drug land. And with their 'special skills', they cut one hell of a swath through their competition."Being in the military can teach you some skills, but the skill that people most commonly associate with the military, (i.e. how to hurt or kill people) doesn't exactly translate well to civilian life. However, there is a way around that for more morally... flexible... people; put those skills to work in crime, especially organized crime, and start picking the local street toughs who are your main competition apart. As a result of this, many fictional criminals who come from a military background tend to be much more effective, dangerous, and capable than everyday thugs. It's also common to show them as being capable of being more ruthless and cold-blooded than more pedestrian criminals. This trope is particularly common if the character in question is a Shell-Shocked Veteran who has been broken by their experiences, a Sociopathic Soldier who was clearly a bad apple while in the service, and the Returning War Vet who finds You Can't Go Home Again may be likely to fall into this. Because Elites Are More Glamorous, expect a character doing this to be from a section of the military either known for being unusually badass, or flat out special forces/covert ops. A companion trope to Lawman Gone Bad. Contrast Badges and Dog Tags, when policemen have an ex-military background. Compare and contrast the Privateer, who was essentially paid by his nation to become a pirate against another nation's shipping, the Rogue Agent, and the Boxed Crook. The inversions are Trading Bars for Stripes, where a character facing prison time or in prison is given the choice of serving in the military instead, and Recruiting the Criminal. May sometimes overlap with Former Regime Personnel.

Films — Live-Action
- Michael Corleone from The Godfather was a US Marine captain in World War II, and although he had wanted to avoid getting entangled in the "family business" in the past, once he does get involved with it, he proves shockingly effective and ruthless in ways his other criminal rivals are completely unprepared for.
- Sonny Wortzik in Dog Day Afternoon tries to keep the police from storming the bank by saying that he and his cohort were in the Army in Vietnam and have no problem getting violent with the hostages.

His relationship with the hostages makes it pretty clear he doesn't intend to hurt them, however.
- Tony Montana of Scarface (1983) is a former Cuban Army soldier who gradually becomes a fearsome Miami cocaine kingpin, known for his badassery and ruthlessness. Tony's military training could explain his deadly skills with firearms, such as an assault rifle and grenade launcher that he uses to kill dozens of enemy gangsters with in the final battle.
- While no attention is drawn to it, Porter from Payback has a USMC tattoo and is a dangerously effective and utterly ruthless criminal who is more than capable of taking down drug dealers, Dirty Cops, Triads, or even The Syndicate if any of them stand in the way of getting back the money his ex-partner stole from him.
- Basic takes place in Panama before the US base closed up there. The film has a rumor going around on base that a group of high level covert ops guys and elite Army Rangers turned to crime and set themselves up as a criminal empire. And since some members of the group were trained by the much feared and hated Sergeant West, who is infamous for making his trainees want to kill him, and West has just gone missing along with a number of his current trainees, it's speculated that they may be behind it. The ending shows that this rumor is false, but the course of the movie shows that the base's commander, Colonel Styles, and several others, including members of the medical staff, were involved in smuggling drugs back to the US and distributing stimulants to soldiers on the base.

- Several Star Wars Legends books (including The Thrawn Trilogy and The Han Solo Trilogy) establish that Han Solo had once undergone officer training in the Imperial Navy, but left the service not long after and turned to being a pilot for hire and smuggler. The Thrawn Trilogy is pretty vague about the details of how/when/why Han left the navy, but The Han Solo Trilogy shows the events in full detail: he was dishonorably discharged for attacking a superior officer to protect the Wookiee slaves he was abusing. One slave, name of Chewbacca, swore a Life Debt to Han and started following him around.

- In near-future thriller Victoria, Dark Messiah John Rumford and his group of militiamen are a Knight Templar example. As rebels against the increasingly dysfunctional and corrupt Federal Government, the veterans who join the Christian Marines are technically criminals, and this is certainly how their enemies see them. Early on, Rumford and his lieutenant, former Gunnery Sergeant Matthews, use military discipline and tactics to rally the downtrodden citizens into a formidable force to take on the ethnic crime gangs who terrorize their neighborhoods, thus building popularity and muscling in on their business. Later, they move on to overt anti-government action.
- In many adaptations of Sherlock Holmes, Holmes' Evil Counterpart Moriarty has a dragon named Sebastian Moran who is an ex-Army officer and Cold Sniper. This actually comes from the original stories, although there, Moran only appears (in just one story) after Moriarty is dead.
- Burn Notice features these quite often:
- Main character Michael went from being a tough street kid to Army Special Forces to CIA legend to someone who works outside the law to manipulate and destroy criminal organizations on a weekly basis while seldom, if ever, being in real danger from the criminals he takes down. His team member Sam Axe is a Navy SEAL who was forced into retirement (circumstances explored in the spinoff Burn Notice: The Fall of Sam Axe).
- Michael's Evil Mentor Larry was once involved in covert ops, and now he's a Faux Affably Evil (and completely psycho) assassin for hire whose solution to every problem is "just start killing people and it'll sort itself out."
- Recurring character Brennan was once Military Intelligence, now he's an Arms Dealer.
- Gilroy went from being involved in black ops for the British government to a Rogue Agent who will do any job, for anyone, anywhere in the world if the pay is right and it amuses him enough. These jobs range from assassination to terrorism for hire to selling nuclear secrets on the black market.
- Occasionally the Villain of the Week will be some flavor of ex-military, and they generally present a much greater danger and more difficult challenge to Team Westen than the crooks and con men they usually deal with. One such case is the ex-Green Berets and Marines operating a heroin ring in the first season finale.
- Both Jimmy Darmody and Richard Harrow from Boardwalk Empire were WWI soldiers who were hardened by their experiences and alienated from their past friends, family, and society in general. While decent enough in many ways, they fall into bootlegging and being hardcore gangsters with few, if any moral qualms, and often prove themselves much more competent and deadly than most of the thugs they encounter.
- A theory among some fans of The Wire is that The Dragon for the Stanfield gang, Chris Partlow, has some sort of military experience based on the way he trains new recruits to the gang. This is commented on In-Universe as well, when Cheese sees the rigid discipline and militant attitude of the Stanfield gang and quips "Y'all some Semper Fi motherfuckas, ain't you? Where Cheese go to enlist?"
- A few of the gangsters in The Sopranos have some military background.
- Corrado "Junior" Soprano, one of the leaders of the DiMeo crime family, was a veteran of World War II.

- Jeremiah Bello from Graceland was a soldier in his home in Nigeria, and after being on the wrong side of a coup, came to Los Angeles and set himself up as a drug kingpin. Mike infiltrates his organization by pretending to be a Marine turning to criminal ventures on the side, and Bello hires him to give his gangsters proper training in guns and marksmanship. Later on Mike gets fellow FBI Agent "Johnny" Tuturro to go undercover in a similar role, aided by Johnny's past as a sailor in the Navy and Navy SEAL trainee.
- The Blacksmith from Daredevil Season 2 is actually Colonel Ray Shoonover, Frank Castle's former officer. He and some of his most loyal men became drug dealers after the war and he is partially responsible for the massacre of the Castle family.
- In The Punisher (2017) series, Billy Russo was a former squadmate of Frank Castle who later formed a private security group and was a part of the conspiracy that led to the death of Frank's family.
- Peaky Blinders is about the rise to power of the eponymous gang in Birmingham after WWI. The gang boss is Tommy Shelby, a former sergeant-major and the majority of the gang members are disaffected veterans. Their military organisation makes them extremely dangerous.
- One episode of Blue Bloods features a Sympathetic Criminal variant when a group of USMC Iraq War vets robs a bank to pay for medical procedures for the leader's husband, a squadmate, when the VA won't. They run headlong into fellow Iraq vet Danny Reagan, who became an NYPD detective instead (following family tradition).
- Malcolm Reynolds and Zoe Washburne from Firefly were a sergeant and a corporal in the Independent Faction army during the Unification War, and are now captain and first mate of a Space Pirate/smuggling crew. Mal likes to insist that "the war's long done; we're all just folk now," but he's still bitter that the Independents lost and will sometimes do things he normally wouldn't (like sheltering River and Simon), just so he can flip the bird to the purple-bellies.
- Leverage: In one episode Eliot, Parker and Hardison foil an attempted assassination by a sniper. Eliot realizes the shooter used to be in the Navy SEALs based on a specific type of watch he was wearing. Eliot also used to be in Spec Ops before he went beyond the bounds of lawful.
- Played several different ways on Rome.
- Zigzagged in the case of Vorenus, who almost does this by accident in the first season. When Vorenus needs to get a Fallen-on-Hard-Times Job, he thinks he's taking a job to be a bodyguard for Erastes Fulmen, a man he mistakenly assumes to be a respected local merchant, but is actually a mobster who wants Vorenus to be an enforcer for him. Vorenus doesn't realize the truth until Fulmen starts trying to beat money out of a "business partner" of his, and Vorenus almost immediately walks out on the job. In the second season, however, Vorenus does become part of the Roman underworld for real, and he lives up to the ruthless stereotype in the description and then some, as the entire Roman underworld come to both fear and loathe him.
- Titus Pullo falls into being a thug/killer for hire in the first season, and becomes Vorenus' right hand man in the second when Vorenus becomes a prominent underworld figure. They also have at least one (and maybe more) fellow legionaries in the mob they lead.

- In The Night Manager, Big Bad Richard Roper employs a mercenary force that seems to be mostly or entirely composed of former soldiers who like the military life and who are unburdened by excessive morality. His big mistake is thinking that his new employee, Jonathan Pine, is a high-end version of the same type, when in fact, Pine has a very different agenda.
- Season 2 of Braquo revolves around a gang called "The Invisibles", the sole survivors of a Légion Etrangère unit dispatched to Angola, led by Colonel Aymeric Dantin.

- In L.A. Noire, the central conflict is around a shipment of military supplies (including weapons and medical grade opiates) stolen by embittered soldiers. Specifically by members of the protagonist's former unit in Okinawa during World War II (partially because they resented him becoming a decorated cop after they fragged him when he ordered them to torch a cave that turned out to be full of civilians).
- Vito Scaletta from Mafia II is ex-military. He served in World War 2, and almost immediately upon arriving home his friend, Joe, convinces him to resort to a life of crime. When he meets Lincoln in III, he asks him about his experiences in Vietnam. Then again, Vito was always a criminal, as the reason he was in WWII was to avoid going to jail after a cop caught him breaking into a store.
- Grand Theft Auto:

- Star Trek Online: The Cardassian-supremacist True Way terrorist organization draws much of its membership from unemployed former Cardassian Guard personnel (following the Cardassian Union's treaty-imposed military reductions).

- Post-WW2, several members of the former Imperial Japanese military ended up becoming members of the Yakuza. The most famous example would likely be Yoshio Kodama, whose wartime government-funded drug smuggling operations gave him the funding and connections to become one of the most powerful and influential post-war Yakuza.
