That's a loaded question.
I guess you'd have to decide on what level of physical or mental impairment, and what jobs.... I mean, it's really a loaded question. Part of the culture of being together and being in uniform is that you're all basically on the same playing field. You've all signed up for the same game. You're all playing by the same rules. You're all in the same dangers together.
The general could talk maybe a bit more about how that might affect morale. Would that create more problems than it would help in the service? I don't know.
