Yes.
Earlier I asked a question about homeless veterans, and I'm not sure I understood one point.
In Canada we're experiencing veterans who have decided to opt out of society and live in missions or live on the street and not be identified as veterans, to not seek help. We often find those individuals with veterans who will go to areas where these individuals congregate as homeless people, at a mission or someplace like that. They find them and bring them back into the system so they can get benefits and so on.
Do I understand from your comments that this is not a very large problem with regard to French veterans? It is a problem we are dealing with, but it doesn't sound as though it's at a similar level in your experience.
