Whenever troops are engaged in combat, following that episode they are debriefed in a proper debriefing session. That can either be handled by a mental health specialist who is available or by a chaplain.
I just want to take a step backwards. Any suicide is unacceptable. If you want to take a look at the suicide rate south of the border right now, which is spiking, we're not anywhere near their ballpark. The reason we're not in their ballpark is that our deployments are six months long. Soldiers, sailors, and air personnel know going in exactly when they're going to return. Our American friends do not have that benefit. We can see light at the end of the tunnel; our American friends cannot. I think we're doing a very good job of addressing the issue of suicides within the Canadian Forces to keep them at the levels they're currently at.
