I absolutely agree that reintegrating into society is a big issue. What they've learned is that their behaviours in the military do not work well in civilian life. They don't know quite how to fit in, and they lose that sense of belonging in normal civilian life.
For example, if you're working in a job in civilian life, you can't be giving orders the same way you give orders in the military. People get angry and you get charged with harassment, and you end up losing your job, etc., and it goes down the line. I think it's quite important to teach people how to cope with that, absolutely.
