Overview
The FSB is responsible for internal security of the Russian state, counterespionage, and the fight against organized crime, terrorism, and drug smuggling. Since 2003, when the Federal Border Guards Service was incorporated to the FSB, it has also been responsible for overseeing border security. The FSB is engaged mostly in domestic affairs, while espionage duties are responsibility of the Russian Foreign Intelligence Service. However, the FSB also includes the FAPSI agency, which conducts electronic surveillance abroad. All law enforcement and intelligence agencies in Russia work under the guidance of FSB, if needed. For example, the GRU, spetsnaz and Internal Troops detachments of Russian Ministry of Internal Affairs work together with the FSB in Chechnya.
The FSB combines functions and powers similar to those exercised by the United States Federal Bureau of Investigation (FBI), Immigration and Customs Enforcement (ICE), the Federal Protective Service, the Secret Service, the National Security Agency (NSA), U.S. Customs and Border Protection, United States Coast Guard, and Drug Enforcement Administration.
The FSB employs about 66,200 uniformed staff, including about 4,000 special forces troops. It also employs about 160,000–200,000 border guards.
