I see you're quite a good shot, kid. Sniper said he wants to test your reaction time. The faster one wins, as he says. As in that film, remember, "The Good, the Bad and the Ugly", only with a bolt-action rifle instead of a revolver. Life here certainly isn’t a movie, but the reaction and the choice of position are very important in the firefight, especially in urban conditions. If you survive this, help yourself to my cowboy hat, I have one around here somewhere. You choose yourself, who you want to be: the good, the bad, or the ugly.
Kill 3 PMC operatives with a bolt-action rifle at close range, less than 25 meters away
You have got a good reaction time since you're still standing here. Grab your new hat, as promised! Go on, shooter, new tests await you.
To do this task, grab a bolt-action rifle. Factory is recommended for this quest as there are ample opportunities to engage PMC's at 25m or closer. Some close quarters locations you can reliably find and attack PMCs at 25m (or less) are in the office with the safe and the locker room. Using flashbangs such as the zarya stun grenade or 23x75mm "Zvezda" flashbang round rounds may be an effective way to prevent PMCs from firing back, as bolt action rifles have slow fire rates. This can also allow you to complete Huntsman path - Controller at the same time.
