I too was confused. Billy Mitchell is a character in the UK soap EastEnders, who has recently been falsely accused of murder.
Mitchell along with Douhet was one of the most important thinkers of military aviation. There’s a 1955 movie, The Court-Martial of Billy Mitchell featuring Gary Cooper as Mitchell, I thought this was what this HN post was about, not some utterly unimportant and meaningless gamer controversy.
I think you have the wrong game, this is Donkey Kong not Call of Duty ;)
He's the closest we've ever come to the US military leading a major attack on its own citizens. He was only stopped by others because of the optics.
