Amn al-Kharji is ISIS foreign intelligence, whose operatives are sent behind “enemy lines” to conduct espionage or plot and perpetrate terrorist operations. But “enemy lines” doesn’t just refer to countries and cities of the West; any areas in Syria controlled by the Free Syrian Army (FSA) or the Assad regime, and thus not technically within the boundaries of the caliphate, require foreign assets to penetrate.
This is crucial for how the organization “expands” in Syria and Iraq—by dispatching sleepers to recruit agents and informants, or gather information about rival groups, be they other militias or state armies. Abu Khaled emphasized repeatedly that tradecraft rather than martial puissance is what makes ISIS so formidable at seizing and keeping terrain.
