Watching this video from Funker Tactical, you will be tempted to call this as "The Dark Arts of Advanced Training" rather than "Dark Side" and makes you wonder if you have been your firearms training right. Instructor Zero goes through several scenarios where it's extremely difficult to shoot effectively which will then be part of a series for this year... "Instructor Zero is set to release a video mini-series focusing on the dark side of advanced training. The actions and demonstrations depicted in this video were performed under medical supervision. Please do not attempt any actions you see this video."
