TFA also specifically refers to military weaponry which is designed for the purpose of taking out equipment rather than a lucky shot. The reason I brought up Ukraine is that it’s the logical implication of your statement whether or not you recognize it: militaries don’t rely on luck, they want to stack the odds in their favor. What makes something military grade is that it can consistently perform that task, not relying on a soldier getting lucky. This is why asides about handgun distances aren’t relevant: in the context of taking out helicopters, we’re not talking about close quarters situations - 3-5 yards means people are getting hit by prop wash or the rotors themselves!
