The half-hour production shows boys aged nine to 12 shooting down first dummies then real captives.
The youngsters sleep in dormitories at the terror training school thought to be in Isis's self-proclaimed capital of Raqqa in Syria.
They are shown taking classes studying execution videos and pledging their allegiance to ISIS.
Then they don combat gear to crawl through brush carrying rifles and snip through a barbed-wire fence toward a training compound.
The kids – one of whom sports a plaster cast on his arm are then set into an abandoned building to shoot dummy targets.
The youngster then move on to live targets prisoners whose hands have been bound behind their backs.
Two of the captives break down in tears after being cornered by the mini mob who wound them then finish them off at point-blank range.
One prisoner cornered on the rooftop throws himself off the edge before being gunned down by a child who dashes downstairs to his victim's body to fire several more shots into his head.
ISIS has bragged about its 'cubs' training program for young terrorists, dailystar reported.

One sang: "Beware, we have what we need to defend ourselves.
"Well-armed soldiers are ready to kill you.
"Beware we are ready to fight back.
