I don't see there is any possibility to explain this clip that he can directly shoot through the smoke and hit the player, and please pay attention to count on numbers he shoot, just 2 and killed, what a nice shoot to kill
In the battlereport link he is using mk11 DMR with ops locker which seems hard to belive to get such a high KD rate
