Intelligence

Intellivence collection disciplines
Intelligence collection disciplines through which the U.S. Intelligence Community (IC) collects intelligence are generally referred to as those which fall within national technical means or non-technical means. Technical means include signals intelligence (SIGINT), measurement and signatures intelligence (MASINT), and imagery intelligence (IMINT). Non-technical means include human intelligence (HUMINT) and open source intelligence (OSINT). Each of these collection disciplines is source-specific &mdash; that is, a technical platform or human source, generally managed by an agency or mission manager, collects intelligence that is used for national intelligence purposes.
