Sniper: Ghost Shooter (2016) on Netflix

Plot summary

Brandon Beckett and Richard Miller work as elite snipers. Their unit is deployed in the Middle East against extremists when the Colonel hands them another assignment: guarding a gas pipeline that carries fuel from Georgia toward Western Europe, a target extremists want to strike for political effect. Skirmishes with the enemy along the line leave U.S. snipers dead, picked off by a ghost shooter who pinpoints exactly where each team has set up. Since the enemy always knows the positions of the shooters, the survivors suspect that someone inside the operation has leaked them, and fingers are pointed at their own people.
