On patrol with the Kurdish Peshmerga battling ISIL
These photos show Kurdish fighters at the front line, sometimes less than one mile away from ISIL fighters. The atmosphere there is tense as the Peshmerga not only must face ISIL forces, but they also have to deal with friendly fire incidents with the Iraqi air force.
The Peshmerga has a long tradition of fighting in the area since the early 20th century. They are well-trained and highly-motivated.
