The images were posted on a Facebook page titled ‘Sgt Tom’, which carries the colours of the Kurdish flag and disguises the faces of all the men photographed. 

The images show the men wearing military fatigues and clothing suited to fighting in a desert environment while clutching large assault rifles. 

Alongside captions making threats towards ISIS militants, one image appears to act a as the group’s manifesto, identifying the leader as the aforementioned ‘Sgt Tom’ who says he is a former serviceman travelling to ‘defeat you [ISIS] and the evil you stand for’.
