Militant Islamic Society

The Militant Islamic Society is an apparently fictional terrorist group which appears in Lessons Learned.

History
MIS's history is not revealed in detail. It appears to originate from real-life terrorist groups like Al-Qaeda. Reid describes it as an "atypical prison organisation", most likely stationed in the U.S. that recruits prisoners that most other groups won't accept through imams (Islamic preachers). It doesn't discriminate ethnicities and is largely made up of American citizens who have a reason to hate the government.

The group first became prominent in Lessons Learned when the DEA made a raid and found a home-made explosive device of Al-Qaeda design, along with chemicals that could be used to weaponize anthrax. The BAU were called in to question Jamal Abaza, aka Jind Allah, a detainee held at Guantanamo Bay, who was linked to it. Eventually, Gideon, Reid and then-new agent Prentiss were able to trick him into revealing the target of the attack: the USA Mall in McLean, Virginia. The MIS operatives killed various security guards blocking their ways, headed up to the building's air vents and prepared to release the anthrax, but were stopped by DEA SWAT, lead by Derek Morgan and shot. The events were then covered up as an attempted robbery attempt. The MIS hasn't been mentioned since then.

Known Victims

 * An unnamed Guantanamo detainee (indirectly, Jamal Abaza manipulated him into suicide)
 * Kenny, a DEA agent (killed in an explosion)
 * Five members (all executed, presumably to remove loose ends)
 * A docking security guard at the USA Mall
 * Attempted to release anthrax onto the USA Mall, but were stopped
