Overview[]
An Intelligence Bulletin (IB) is an intelligence report that highlights new developments or trends. They are more limited in focus and depth than Intelligence assessments (IAs), but as finished intelligence products go beyond reporting raw information. They create context for the new information and may offer an analytic judgment regarding its importance and impact. IBs are generally one to three pages in length, and like IAs, are approved for dissemination by the Section Chief in the relevant DI Analytical Section.
