asked to acknowledge transgender people as human beings, or lord forbid, a black pilot is flying their plane.

I don't know about the trans bit, but I expect servicemen will be a bit more tolerant of black people: I'm of the opinion that black people are over-represented in the military since they are also far more likely to be from economically disadvantaged areas and thus more likely to enlist so they can get any job vs none.

One of my workmates immigrated to Canada to be with a really sweet and beautiful girl, but his background is Montgomery, Marines artillery, and Navy. He said a massive portion of servicemen are either out of prison or avoiding the poverty-driven choices that leads to prison. He's the only one of his childhood friend group who is not in a cell or a grave right now.

So I would anticipate servicemen to be aware of class struggle a bit more, and will have learned that blood is thicker than water.
