The question appears to be referencing a specific dynamic or scene from the movie franchise 

Sicario, as the search results focus entirely on the plots, characters, and themes of the films Sicario and Sicario: Day of the Soldado. 

In the context of the films, “sicarios” (hitmen) do not necessarily “hint” at each other, but the characters operate in a world of shifting alliances and brutal conflict, where violence between individuals and groups is a constant: 

• Conflict and Betrayal: The core of the films involves U.S. government agents, a former prosecutor turned hitman (Alejandro Gillick), and cartels all operating with their own agendas, leading to frequent conflict and betrayal. Characters like Matt Graver and Alejandro use and manipulate others, and sometimes come into conflict themselves.
• “Land of Wolves”: A key theme is the breakdown of the rule of law at the U.S.-Mexico border. The environment is a “land of wolves,” where violence and self-interest dictate survival, and alliances are temporary.
• Specific Antagonism: In Day of the Soldado, Matt Graver is ordered to kill Alejandro after their mission goes off the rails, leading to a hunt where they are briefly antagonists, though this is ultimately unresolved.
• Ending of the First Film: The first film ends with Alejandro threatening the FBI agent Kate Macer at gunpoint to sign a document that legalizes the illicit operation, showing a power dynamic and ideological clash, not “hinting” at another sicario. 

“Mafia hit men” refers to individuals who carry out contract killings for organized crime syndicates, particularly the Mafia

. Historically, their ruthlessness has been a key component for advancement within crime families, but also a reason for them to be targeted themselves, as they possess extensive knowledge of the organization’s activities. 

Notorious individuals have included members of groups like the American “Murder, Inc.,” which acted as an enforcement arm for the National Crime Syndicate from the 1920s to the 1940s. 

Notable Mafia hit men include:

• Albert Anastasia: Co-founded Murder, Inc. and became the boss of the Mangano (later Gambino) crime family. He was known as one of the most feared hit men of his time.
• Giovanni Brusca: A Sicilian Mafia killer most known for the car bomb assassination of anti-Mafia prosecutor Giovanni Falcone in 1992.
• Roy DeMeo: A member of the Gambino family, his crew was infamous for the “Gemini Method” of dismembering victims and disposing of the remains in boxes to avoid detection.
• Sammy “The Bull” Gravano: The underboss for John Gotti in the Gambino crime family, he confessed to 19 murders before becoming an FBI informant and helping to bring down Gotti.
• Richard Kuklinski: Known as the “Iceman,” he was a contract killer for the Mafia who claimed to have committed over 200 murders using a variety of methods.
• Benjamin “Bugsy” Siegel: A key figure in the formation of the National Crime Syndicate, he was known for his expertise with firearms and played a significant role as a hit man during the Prohibition era. 

Mob hit men often used violence to prove loyalty and gain status. Their activities have been chronicled in historical accounts and documentaries, such as those detailed by The Mob Museum in Las Vegas. 

“Cartel hit men” (known in Spanish as 

sicarios) are individuals employed by organized crime syndicates, primarily Mexican and Colombian drug cartels, to carry out assassinations, kidnappings, torture, and enforcement activities. 

Key Characteristics and Activities

• Role in Cartels: Hit men serve as the enforcement arm of drug trafficking organizations, engaging in violence to control territory (plaza boss), settle debts, eliminate rivals, and maintain discipline and fear.
• Methods: Their methods are often brutal, including torture, beheadings, dismemberment, and public displays of bodies to send messages to rivals and authorities.
• Recruitment: Recruitment into this life can happen at a young age, with some individuals as young as 12 or 15 years old being groomed into the organizations, often from street gangs.
• Motivation: Financial incentives, a sense of “family” within the gang, or fear of being killed for disobedience are common factors driving their involvement.
• Impact: Their activities contribute to extreme violence in regions affected by cartel operations, impacting public safety in both Mexico and the United States. 

Notorious Examples

Several individuals identified as cartel hit men have gained notoriety through confessions, high-profile arrests, and media coverage: 

• Jhon Jairo Velásquez (“Popeye”): A former hit man for Pablo Escobar’s Medellín cartel, who confessed to hundreds of murders and organizing thousands more.
• José Manuel Martínez (“El Mano Negra”): A California-based hit man and serial killer who confessed to dozens of murders across multiple U.S. states, mostly related to drug debts.
• Martin Corona: A former enforcer for the Tijuana cartel who became a government informant and entered witness protection, co-authoring the book Confessions of a Cartel Hit Man.
• Gabriel Cardona: An American teenager from Texas who was recruited by the Zetas cartel at age 15 and became a hit man as part of an elite crew of U.S. citizen assassins operating on both sides of the border.
• Mario Iglesias-Villegas (“El 2,” “Grim Reaper”): A leader of a group of Sinaloa Cartel assassins responsible for the deaths of thousands in Ciudad Juarez between 2008 and 2011, who was later sentenced to life in prison in the U.S.. 

Law enforcement agencies like the DEA and FBI actively investigate and prosecute cartel members, including hit men, often through coordinated international efforts. Information on ongoing investigations and fugitives can be found on official U.S. government websites, such as the Drug Enforcement Administration (DEA) or FBI.
