Holey crap!, talk about a badass. Did they all come at him one by one, like in the movies
Considering the setting, a narrow train aisle, they probably could come at him only one-at-a-time. That and he may or may not have been using one of them as a shield.
Badass of the week nominee.
Kind of hard to rush as a mob on a train.
I would reckon that the aisleway between the seats helped channel his adversaries into a linear target. Once one went down, he then had access to the next one, and so on. And since he was presumably lacking body armor, holding up the sliced and diced carcass of the first one he had dealt with made an acceptable field expedient substitute, as well as presenting a nice example to the others as to what was coming their way.
AYO GHORKHALI!
I doubt it — this guy’s a Gurkha, he probably rushed at them melee-style.
