The National Security Agency (NSA) is the major SIGINT organization of the US, with other SIGINT activities in other parts of the intelligence community. There is SIGINT capability in several other agencies, often concerned with just one aspect, such as collection or tactical use. US military forces all have tactical SIGINT and COMSEC (Communications Security) units. The director of NSA wears a "second hat" as the director of the Central Security Service, which coordinates the military operations, which may both make use of national resources (i.e., TENCAP, or Tactical Exploitation of National Intelligence Capabilities) or provide data to the strategic analysts elsewhere in the intelligence community. There is a limited cryptanalytic capability, principally aimed at domestic criminals, in the Federal Bureau of Investigation (FBI). CIA has some joint activities with NSA, which may include the covert or clandestine placement of SIGINT sensors.
US doctrine includes a flexible interface between the strategic and tactical, in military operations. Under the TENCAP program, warfighters can benefit from systems intended for the national intelligence level. Under the complementary Tactical Intelligence and Related Activities (TIARA) programs, tactical units acquiring information of interest to the national level can feed it up the chain to the appropriate organizations.
The interaction of the US intelligence community, especially COMINT, for domestic law enforcement and counterterrorism is extremely complex, balancing civil liberties versus security needs. There is no consensus on this balance and the matter is very controversial.

Famous quotes related to united states:
“And hereby hangs a moral highly applicable to our own trustee-ridden universities, if to nothing else. If we really wanted liberty of speech and thought, we could probably get itSpain fifty years ago certainly had a longer tradition of despotism than has the United Statesbut do we want it? In these years we will see.”
—John Dos Passos (18961970)
“The United States themselves are essentially the greatest poem.”
—Walt Whitman (18191892)
“Americarather, the United Statesseems to me to be the Jew among the nations. It is resourceful, adaptable, maligned, envied, feared, imposed upon. It is warm-hearted, overfriendly; quick-witted, lavish, colorful; given to extravagant speech and gestures; its people are travelers and wanderers by nature, moving, shifting, restless; swarming in Fords, in ocean liners; craving entertainment; volatile. The schnuckle among the nations of the world.”
—Edna Ferber (18871968)
“So here they are, the dog-faced soldiers, the regulars, the fifty-cents-a-day professionals riding the outposts of the nation, from Fort Reno to Fort Apache, from Sheridan to Stark. They were all the same. Men in dirty-shirt blue and only a cold page in the history books to mark their passing. But wherever they rode and whatever they fought for, that place became the United States.”
—Frank S. Nugent (19081965)
“United States! the ages plead,
Present and Past in under-song,
Go put your creed into your deed,
Nor speak with double tongue.”
—Ralph Waldo Emerson (18031882)
