No serious training or equipment would be required for this close of a shot. I've taken deer over 200 yards away with my $500 rifle, no training other than shooting on and off since I was a kid.
High pressure.
Under pressure, a poorly trained person is unlikely to be capable of this. It takes some degree of training to simultaneously deal with this pressure and still perform.
Yes, this is the level of training I imagine as sufficient. A match applies pressure: you're on a clock, there is an audience, you have a safety regime and people scrutinizing you on it, and at the end, there is a score. I don't claim Fort Benning sniper school is necessary. Only that you likely can't just wander out of a gun shop with your scoped deer rifle at any price and snipe targets at range under pressure: there is more to it than the weapon.
> Combat trained random people are probably more common than you think.
I listed a wide variety of people with the training I believe is sufficient.
Training.
