In France, we have what we call Écoute défense. This is a telephone help system that operates around the clock and that can respond to wounded soldiers in possible distress. The line is also open to families.
What I am describing is an emergency line that can help someone at critical moments. But there is also long-term support. That is run by the Service de santé des armées. The service provides psychiatrists and psychologists whose responsibility is to provide long-term support to soldiers and families.
