A great many soldiers have (and were, going back to the first world war at least) been hospitalised because the war was affecting their mental health.I’m not being unsympathetic to his issues but millions of soldiers went through far worse in various wars seeing their colleagues killed in front of them and they had to get on with it , they couldn’t ask to be hospitalised because it was effecting their mental health .
I'd like to think we've moved on from the days when people might be shot for not being able to cope.
