A collection of ISIS personnel records obtained by NBC News and analyzed by experts at West Point provides new insight into the group's ambition and the people who make up the group.
The files reveal that the jihadists who joined the Islamic State in 2013 and 2014 were largely uninterested in suicide missions, better educated than expected and, to the alarm of those trying to stop the export of terror, very well-traveled.
NBC News received the dossiers from a Syrian man who said he stole the information, stored on a flash drive, from a senior ISIS commander. Over the last month, NBC News has worked with the Combating Terrorism Center at the elite military academy to transform them into a database of more than 4,000 foreign fighters from 71 countries.
"The largest takeaway from these documents is the massive diversity of the population," Brian Dodwell, deputy director of the Combating Terrorism Center at West Point, told NBC News.
