One of ISIS' top commanders was a 'star pupil' of US-special forces training in the country of Georgia
Sporting a recognizable red beard and happy to pose for photos, Shishani has acted as a very public face for some of ISIS' most notorious successes.
It was Shishani who posed with the stolen US Humvees that ISIS had seized from Mosul and brought back into Syria. And it was Shishani who had led successful ISIS military campaigns throughout Syria as well as a blitz through western Iraq that put the group within 100 miles of Baghdad.
These military successes are not simply the result of any innate military capabilities. Instead, Shishani spent years conducting military campaigns against the Russians first as a Chechen rebel and then as a soldier in the Georgian military. During Shishani's four years in the military, from 2006 to 2010, his unit received some degree of training from American special forces units.
