Two years ago Abu Tahseen, a now 63-year-old sniper, joined the resistance against ISIS. Since he joined up he has killed over 300 extremist fighters as he battles to free his homeland from jihadi forces.
Mr Tahseen is a veteran of five wars and has volunteered with Iraq's Popular Mobilisation Units, where he's put his deadly skills to use by killing 321 ISIS fighters since 2015, The Mirror reports.

In the video which was filmed last year, Mr Tasheen talks through his mind-set as he works.
He says: "You see this area? I guarantee to God no one would come up it. I'm relaxed. My mind is relaxed.
"When I get my rotation I just want to get back here. Last time they gave me a month off and after 12 days I came back."
According to Mr Tasheen, his rifle is capable of blowing a man a metre back when they're struck by the bullet.
He also claims that he's so accurate that ISIS fighters have become afraid to walk through the mountains.
Mr Tasheen is just one of many volunteer fighters, many of whom fought ISIS in Syria but returned to defend Iraq when the group gained a foothold in the country.
