Chapter 3 “Pyrrhus Evac” – Salach District, you come to a part where Sev is on higher ground and speaks to Rico who is on the ground and next to an Anti-Air weapon. A sniper rifle lies in the corner of where you’re standing. You need to take the rifle and kill 6 enemies with 6 shots. After you fire 6 shots Sev automatically reloads the gun. There are plenty of enemies around but try to aim above the chest for confirm kills. The snipers in adjacent buildings are good targets as they go down easier than the ones on the ground. They are easy to spot because their rifles have red laser target designators. There are also opportunities in later chapters for this trophy.
