Photographer Younes Mohammad spent three days with soldiers from the Kurdish Peshmerga at their base in Sinjar, Iraq.
The risk of sniper fire is so high that Peshmerga are forced to use a mirror to perform reconnaissance on enemy positions.
Younes said: “Normally IS attack the Peshmerga two or three times a day, but sometimes it is only once.
"Peshmarga watch IS movements with a mirror, they can not look over the defences because of sniper fire."
ISIS reached Sinjar in August 2014, massacring thousands of Yazidis before US airstrikes enabled the evacuation of an estimated 50,000 men and women from Mount Sinjar.
The Peshmerga now hold only 10% of the town and are ambushed daily by ISIS fighters attempting to move through the settlement to the north.
However, despite their territorial disadvantage, the Peshmerga fighters are able to use their fortified base to identify ISIS positions to be taken out by Coalition airstrikes.
Younes added: "On Sinjar mountain even after a year has passed we can still see people`s cars that have run away from the town and were not successful.
“Hundreds of civilians still live in the northern part of the city protected by the Peshmerga as IS have taken over the rest of the town.
“The Peshmerga forces let their command centre know where IS bases are located so that they can plan Coalition airstrikes in the area.”
