I'll ask Scott and Rakesh to speak, but what I will say first is we have Canadian Forces members who are amputees. We have Canadian Forces members who are suffering from OSIs, operational stress injuries, and PTSD who do not breach universality of service, who continue to be warriors in the Canadian armed forces.
In terms of the invisible illness, if a member has post-traumatic stress disorder or a serious enough operational stress injury, it does not mean they cannot function as an individual out in society. As a matter of fact, they can prosper and we have so many examples of that.
When we diagnose someone and identify that they breach universality of service, it's because we do not want to put them in a position of more fighting where they would experience another traumatic incident that really could do permanent damage. That's our criteria.
In terms of visible and invisible, I'd ask Dr. Jetly to comment.
