The purpose of this report is to provide an analysis of over 4,600 unique Islamic State personnel records that were produced by the group primarily between early 2013 and late 2014. The importance of this data for understanding the Islamic State and, in particular, the foreign fighter flow, cannot be overstated. To put it simply, it is the largest cache of primary source documents produced by the Islamic State available in the open-source as of this date.
These particular documents were acquired by NBC News from an Islamic State defector and sub- sequently provided to the Combating Terrorism Center at West Point (and other entities). This re- port provides a window into the organization’s global workforce, revealing information about foreign fighters’ countries of origin, citizenship, points of entry into Syria, marital status, skills and previous occupations, education levels, religious knowledge, fighting role preferences in the group, and previous jihadist experience. In addition to analyzing the data at the macro-level, the report also highlights numerous anecdotes of individual fighters. Taken together, the analysis in this report reveals an organization that is attempting to vet new members, manage talent effectively within the organization, and deal with a diverse pool of recruits.
