Organized crime in the context of "National Guard of Ukraine"

National security, or national defence (national defense in American English), is the security and defence of a sovereign state, including its citizens, economy, and institutions, which is regarded as a duty of government. Originally conceived as protection against military attack, national security is widely understood to include also non-military dimensions, such as the security from terrorism, minimization of crime, economic security, energy security, environmental security, food security, and cyber-security. Similarly, national security risks include, in addition to the actions of other states, action by violent non-state actors, by narcotic cartels, organized crime, by multinational corporations, and also the effects of natural disasters.

Governments rely on a range of measures, including political, economic, and military power, as well as diplomacy, to safeguard the security of a state. They may also act to build the conditions of security regionally and internationally by reducing transnational causes of insecurity, such as climate change, economic inequality, political exclusion, and nuclear proliferation.

A protection racket is a racketeering scheme, usually perpetrated by a criminal organization, that coerces payments on a regular basis from an individual or group in exchange for agreeing to not harm them (or for supposedly "protecting" them). The threat of harm may be indirectly communicated or implied, and it may include violence, robbery, ransacking, arson, vandalism, etc. The payments are called "protection money" or a "protection fee". An organized crime group determines an affordable fee by negotiating with each of its payers to help ensure a consistent and punctual payment. Protection rackets can vary in terms of their levels of sophistication or organization.

The perpetrators of a protection racket may protect vulnerable targets from other dangerous individuals and groups or may simply offer to refrain from themselves carrying out attacks on the targets, and usually both of these forms of protection are implied in the racket. Due to the frequent implication that the racketeers may contribute to harming the target upon failure to pay, the protection racket is generally considered a form of extortion. In some instances, the main potential threat to the target may be caused by the same group that offers to solve it in return for payment, but that fact may sometimes be concealed in order to ensure continual patronage and funding of the crime syndicate by the coerced party. In other cases, depending on the perpetrators' level of influence with authorities and the legality of the business being protected, protection rackets may also offer protection against law enforcement and police involvement, especially if the perpetrators bribe or threaten local law enforcement.

Transnational organized crime (TOC) is organized crime coordinated across national borders, involving groups or markets of individuals working in more than one country to plan and execute illegal business ventures. To achieve their goals, these criminal groups use systematic violence and corruption. Common transnational organized crimes include conveying drugs, conveying arms, trafficking for sex, toxic waste disposal, materials theft and poaching.

A gang is a group or society of associates, friends, or members of a family with a defined leadership and internal organization that identifies with or claims control over territory in a community and engages, either individually or collectively, in illegal, and possibly violent, behavior, with such behavior often constituting a form of organized crime.

A gangster (informally gangsta) is a criminal who is a member of a gang. Most gangs are considered to be part of organized crime. Gangsters are also called mobsters, a term derived from mob and the suffix -ster. Gangs provide a level of organization and resources that support much larger and more complex criminal transactions than an individual criminal could achieve. Gangsters have been active for many years in countries around the world. Gangsters are the subject of many novels, films, television series, and video games.

A crime family is a unit of an organized crime syndicate, particularly in the Sicilian Mafia and Italian-American Mafia, often operating within a specific geographic territory or a specific set of activities. In its strictest sense, a family (or clan) is a criminal gang, operating either on a unitary basis or as an organized collection of smaller gangs (e.g., cells, factions, crews, etc.). In turn, a family can be a sole "enterprise" or part of a larger syndicate or cartel. Despite the name, most crime families are generally not based on or formed around actual familial connections, although they do tend to be ethnically based, and many members may in fact be related to one another. Crime "families" tend to be associated more directly with their respective territories than the individuals to whom their members may or may not be related.

The American Mafia, commonly referred to in North America as the Italian-American Mafia, the Mafia, or the Mob, is a highly organized Italian-American criminal society and organized crime group. The terms Italian Mafia and Italian Mob apply to these American-based organizations, as well as the separate yet related Sicilian Mafia or other organized crime groups in Italy, or ethnic Italian crime groups in other countries. These organizations are often referred to by its members as Cosa Nostra (Italian pronunciation: [ˈkɔːza ˈnɔstra, ˈkɔːsa -]; lit. 'Our Thing') and by the American government as La Cosa Nostra (LCN). The organization's name is derived from the original Mafia or Cosa Nostra, the Sicilian Mafia, with "American Mafia" originally referring simply to Mafia groups from Sicily operating in the United States.

The Mafia in the United States emerged in impoverished Italian immigrant neighborhoods in New York's East Harlem (or "Italian Harlem"), the Lower East Side, and Brooklyn; also emerging in other areas of the Northeastern United States and several other major metropolitan areas (such as Chicago and New Orleans) during the late 19th century and early 20th century, following waves of Italian immigration especially from Sicily and other regions of Southern Italy. Campanian, Calabrian and other Italian criminal groups in the United States, as well as independent Italian-American criminals, eventually merged with Sicilian Mafiosi to create the modern pan-Italian Mafia in North America. Today, the Italian-American Mafia cooperates in various criminal activities with Italian organized crime groups, such as the Sicilian Mafia, the Camorra of Campania and the 'Ndrangheta of Calabria. The most important unit of the American Mafia is that of a "family", as the various criminal organizations that make up the Mafia are known. Despite the name of "family" to describe the various units, they are not familial groupings.

The Russian mafia (Russian: ру́сская ма́фия, romanized: russkaya mafiya [ˈruskəjə ˈmafʲɪjə] or росси́йская ма́фия, rossiyskaya mafiya [rɐˈsʲijskəjə ˈmafʲɪjə]), also known as bratva (братва́, bratva [brɐtˈva]; lit. 'brothers' clique'), is a collective of various organized crime related elements originating and operating in Russia. Any of the mafia's groups may be referred to as an "Organized Criminal Group" (OPG, from Russian "организованная преступная группа"). This is sometimes modified to include a specific name, such as the Orekhovskaya OPG. Sometimes, the Russian word is dropped in favour of a full translation, and OCG is used instead of OPG.

In December 2009, Timur Lakhonin, the head of the National Central Bureau of Interpol within Russia, stated that "Certainly, there is crime involving our former compatriots abroad, but there is no data suggesting that an organized structure of criminal groups comprising former Russians exists abroad" on the topic of international Russian criminal gangs. In August 2010, Alain Bauer, a criminologist from France, said that the Russian mafia "is one of the best structured criminal organizations in Europe, with a quasi-military operation" in their international activities.
