From the Document: "The Intelligence Community (IC) is charged with providing insight into actual or potential threats to the U.S. homeland, the American people, and national interests at home and abroad. It does so through the production of timely and apolitical products and services. Intelligence products and services result from the collection, processing, analysis, and evaluation of information for its significance to national security at the strategic, operational, and tactical levels. Consumers of intelligence include the President, National Security Council (NSC), designated personnel in executive branch departments and agencies, the military, Congress, and the law enforcement community. The IC comprises 17 elements, two of which are independent, and 15 of which are component organizations of six separate departments of the federal government. Many IC elements and most intelligence funding reside within the Department of Defense (DOD)."
