Yeah I had to follow a bunch of the links to figure this out, but in short, he runs an air combat training company, and the Air Force and Navy pay him to field a training “adversary” for the military pilots to fight in mock combat.
From further reading it sounds like the idea here is to get a diverse and different field of aircraft. I guess the NATO forces can practice against each other, but it’s not realistic in the sense that any opposition they would face in a real war would theoretically be using very different equipment. So guys like Air USA are paid to conjure up a fleet of all kinds of aircraft, and pilots to fly them, which will act as more legitimate test.
