Several generations of the prominent Kurdish Barzani family have been fighting on the front lines to defend their land.
Iraqi Kurdish regional President Massoud Barzani's son, Mansour Barzani, is the Commander of the Peshmerga Special Forces. His son, Yasser, fights next to him.
Instead of finishing college, Yasser left the United States last year to return to the Kurdish region in Iraq and help battle Islamic State (IS) militants.
"I wanted to come here and be part of this," said Yasser, who could be easily confused with one of the European special forces aiding the peshmerga. "I had so many other choices but I chose this myself."
