The roles of National Intelligence Organizations

National intelligence organizations employ specialized resources and dedicated personnel to gain information about potential adversaries, events, and other worldwide intelligent reports (IRs). The national intelligence organizations routinely provide support to the Joint Forces Commander (JFC) while continuing to support national decision makers. However, the focus of these national organizations is not evenly split among intelligence customers and varies according to the situation and competing requirements. The intelligence community (IC) refers in the aggregate to those Executive Branch agencies and organizations that are funded in the National Intelligence Program. The IC consists of 17 member organizations. The Department of Homeland Security (DHS) is one of the IC members. The DHS Office of Intelligence and Analysis website defines its mission to equip the Homeland Security Enterprise with the intelligence and information it needs to keep the homeland safe, secure, and resilient.

How can DHS leverage Department of Defense resources to analyze vulnerabilities? How much authority should the U.S. military have in domestic matters? If it is a large role, how does Defense Intelligence come in to play? What role(s) do the National Guard Bureau and State National Guard have in domestic intelligence support?
