The U.S. intelligence community recently reaffirmed its conclusion that senior officials in Russia were behind hacks during the 2016 presidential campaign into the Democratic National Committee and emails belonging to associates of Hillary Clinton.

But what exactly is the “intelligence community?” It’s not just an amorphous term for all U.S. intelligence officials. It’s a veritable alphabet soup of 17 agencies and offices. The group includes agencies strictly focused on intelligence as well as the intelligence arms of other government agencies and of the military. Its total budget in 2015 was $66.8 billion.

Here are the 17 offices:

1. Office of the Director of National Intelligence

Created by Congress in response to the terrorist attacks of Sept. 11, 2001, the office coordinates intelligence collection and sharing among U.S. intelligence agencies. The director is the head of the intelligence community and the principal advisor to the president, National Security Council and Homeland Security Council on intelligence matters related to national security.

2.Central Intelligence Agency

The CIA is the most recognized intelligence agency, known for spying on foreign governments and conducting covert operations, including funneling money to opposition groups in other countries to sway elections or oust certain foreign leaders.

3. National Security Agency

Once so secret it was referred to as “No Such Agency,” the NSA is the largest and perhaps most technologically sophisticated of all the intelligence agencies. It focuses on signals intelligence — monitoring, collecting and processing communications and other electronic information — and cracking secret codes. It also protects U.S. information systems from outside penetration. The NSA oversees PRISM and other mass surveillance programs revealed by Edward Snowden in 2013. It is believed to employ more mathematicians than any other organization in the country — a fact not all math whizzes are happy about.

4. Defense Intelligence Agency

The Pentagon’s top spy agency, the DIA is the primary entity responsible for collecting and analyzing intelligence on foreign militaries, with support from the intelligence offices of all the military branches. The DIA shares this information with military leaders, fighters and defense policy makers in order to “prevent and decisively win wars,” according to its mission statement.

5. Federal Bureau of Investigation

The FBI has both law enforcement and intelligence functions. On the intelligence side, it aims to protect the U.S. against terrorism, cyberattacks and foreign intelligence operations and espionage. It maintains the government’s terrorist watch list and has been involved in the interrogation of “high-value” detainees, sometimes clashing with the CIA.

6. Department of State – Bureau of Intelligence and Research

This bureau collects and analyzes intelligence on global affairs and advises the secretary of State and other diplomats. It conducts foreign opinion polls and tracks and analyzes issues that may undermine U.S. foreign policy objectives, such as weapons proliferation, human trafficking and drug smuggling. Though it’s one of the smallest intelligence agencies, its assessment on weapons of mass destruction in Iraq was not as inaccurate as that of other agencies.

7. Department of Homeland Security – Office of Intelligence and Analysis
