It's bugging me.
What does "DO5" stand for?
(U) JFIC's Asymmetric Threat Division (DO5)Deep Operations, Division of Intelligence Operations, Directorate of Operations, Dude Overboard...
(U) In 1999, the JFIC created the Asymmetric Threat Division (DO5) to take a non-traditional approach to analysis. The Director of Operations recruited JFIC personnel from the command based upon their counterintelligence and counterterrorism expertise. The DO5 provided current intelligence briefings and produced the Worldwide Terrorist Threat Summary in support of the USJFCOM Intelligence staff. The DO5 also provided support to the Joint Task Force-Civil Support (JTF-CS). The JTF-CS assisted civil authorities with disaster assistance. The DO5 supported the JTF-CS exercises by establishing fictional terrorist organizations that would mimic real world terrorist groups. In the summer of 2001, the DO5 was realigned under the Intelligence Watch Center.
JFIC [...] stated that DO5's emphasis was on force protection for the USJFCOM components.
