Federal Security Service in the context of "Border Security Zone of Russia"

The Federal Bureau of Investigation (FBI) is the primary federal law enforcement agency in the United States and also the American domestic intelligence and security service. An agency of the United States Department of Justice, the FBI is a member of the U.S. Intelligence Community and reports to both the attorney general and the director of national intelligence. A leading American counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes. The FBI maintains a list of its top 10 most wanted fugitives.

Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence.

Vladimir Vladimirovich Putin (born 7 October 1952) is a Russian politician and former intelligence officer who has served as President of Russia since 2012, having previously served from 2000 to 2008. Putin also served as Prime Minister of Russia from 1999 to 2000 and again from 2008 to 2012. He has been described as the de facto leader of Russia since 2000.

Putin worked as a KGB foreign intelligence officer for 16 years, rising to the rank of lieutenant colonel. He resigned in 1991 to begin a political career in Saint Petersburg. In 1996, he moved to Moscow to join the administration of President Boris Yeltsin. He briefly served as the director of the Federal Security Service (FSB) and then as secretary of the Security Council of Russia before being appointed prime minister in August 1999. Following Yeltsin's resignation, Putin became acting president and, less than four months later in May 2000, was elected to his first term as president. He was reelected in 2004. Due to constitutional limitations on two consecutive presidential terms, Putin served as prime minister again from 2008 to 2012 under Dmitry Medvedev. He returned to the presidency in 2012, following an election marked by allegations of fraud and protests, and was reelected in 2018.

The Foreign Intelligence Service (SVR) is the civilian foreign intelligence agency of Russia. The SVR succeeded the First Chief Directorate of the KGB in December 1991. The SVR has its headquarters in the Yasenevo District of Moscow with its director reporting directly to the President of the Russian Federation.

Unlike the Russian Federal Security Service (FSB), the SVR is tasked with intelligence and espionage activities outside the Russian Federation. A small service, it works collaboratively with its military intelligence counterpart, the Main Intelligence Directorate, better known as the GRU. As of 1997, the GRU reportedly deployed six times as many spies in foreign countries as the SVR. The SVR is authorized to negotiate intelligence-sharing arrangements with foreign governments, particularly on matters of counterterrorism, and is tasked with providing finished intelligence products to the Russian president.

Igor Vsevolodovich Girkin (Russian: И́горь Все́володович Ги́ркин, IPA: [ˈiɡərʲ ˈfsʲevələdəvʲɪdʑ ˈɡʲirkʲɪn]; born 17 December 1970), also known by the alias Igor Ivanovich Strelkov (Russian: И́горь Ива́нович Стрелко́в, IPA: [ˈiɡərʲ ɪˈvanəvʲɪtɕ strʲɪlˈkof]), is a Russian army veteran and former Federal Security Service (FSB) officer who played a key role in the Russian annexation of Crimea, and then in the Donbas War as an organizer of militant groups in the Donetsk People's Republic (DPR). In 2024 he was convicted on charges of inciting extremism. Earlier he received a life sentence in absentia in the Netherlands for his role in downing the Malaysia Airlines Flight 17.

Girkin admitted responsibility for sparking the Donbas War in eastern Ukraine when, in April 2014, he led a group of armed Russian militants who seized Sloviansk. His role in the siege gained him influence and attention, and he was appointed to the position of Minister of Defense in the Donetsk People's Republic, a puppet state of Russia. Girkin was charged with terrorism by Ukrainian authorities. He has also been sanctioned by the European Union, United States, United Kingdom, Australia, Japan, Canada and Switzerland for his leading role in the war in eastern Ukraine.

The Russian commando frogmen (Russian: Морской спецназ, romanized: Morskoy spetsnaz), informally called "commando frogmen" in civilian media, are a Russian Naval Spetsnaz unit under operational subordination to the GRU that specialized in amphibious reconnaissance to prepare for amphibious warfare operations, clandestine operation, defense against swimmer incursions, direct action against important strategic or tactical goals, irregular warfare, ISTAR, maritime counterterrorism and hostage rescue, and naval special warfare. It is the special forces unit of the Russian Naval Infantry and is composed of highly trained and elite marines within the Naval Infantry. By virtue of belonging to the Russian Naval Infantry, frogmen fall under the Coastal Troops of the Russian Navy service arm. The Russian Navy proper does not field any special forces or special operations forces. Russian FSB special forces Alpha Group and Vympel also have frogman units in their respective naval components.

Yidongyuan (Chinese: 颐东苑社区; pinyin: Yídōngyuàn shèqū; lit. 'East Summer Palace Garden') is a government compound in Beijing, China which serves as the headquarters of the Ministry of State Security (MSS). The facility consists of an office complex and residential community occupying a full city block in the Xiyuan area of Beijing's Haidian District. Closed to the public, and separated by a perimeter wall, the secretive nondescript facility is believed to be staffed by approximately 10,000 intelligence officers and support staff.

Unlike foreign counterparts such as the American CIA's George Bush Center for Intelligence, the SIS Building housing the British MI6, or the Lubyanka Building of Soviet KGB and Russian FSB, Yidongyuan is distinct in housing employees and their families in apartments on site.
