When we talk about psychological stresses, I would say the trigger is obviously different. It could be a flipped-over rigid hull inflatable boat that you happen to be in, or a line that breaks and hits your friend next to you during replenishment at sea, or some other type of trauma, such as body recovery for clearance divers. So I would say the incident that triggers the operational stress injury may be different, but the symptoms are otherwise undifferentiated.
We have folks on army deployments, our explosive ordnance disposal experts, and of course our so-called purple trades—our medical folks, our cooks, and our other support trades, who deploy with the army and then come back into the navy formations, and then dwell with us.
So it's really a hodgepodge of issues. We're talking about the same issues, but obviously we don't have the numbers the army does.
