context_page_description: The Federal Bureau of Investigation is the domestic intelligence and security service of the United States and its principal federal law enforcement agency. Operating under the jurisdiction of the United States Department of Justice, the FBI is also a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counter-terrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes.
  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 the Russian FSB. Unlike the Central Intelligence Agency, 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.
context_section_description: The FBI is organized into functional branches and the Office of the Director, which contains most administrative offices. An executive assistant director manages each branch. Each branch is then divided into offices and divisions, each headed by an assistant director. The various divisions are further divided into sub-branches, led by deputy assistant directors. Within these sub-branches, there are various sections headed by section chiefs. Section chiefs are ranked analogous to special agents in charge.
  Four of the branches report to the deputy director while two report to the associate director. The functional branches of the FBI are:
  FBI Intelligence Branch
  FBI National Security Branch
  FBI Criminal, Cyber, Response, and Services Branch
  FBI Science and Technology Branch
  FBI Information and Technology Branch
  FBI Human Resources Branch
  The Office of the Director serves as the central administrative organ of the FBI. The office provides staff support functions (such as finance and facilities management) to the five function branches and the various field divisions. The office is managed by the FBI associate director, who also oversees the operations of both the Information and Technology and Human Resources Branches.
