I reinforce that. In our case, in our battle group, again it wasn't PTSD, but the combat stress reactions that we had in theatre ranged from the youngest soldier to seasoned senior NCOs and officers as well.
The thing I'd add, though, was that I was very satisfied—and I attributed it to our training as well—that given the significant amount of combat the battle group went through, we only had four combat stress reactions that required return to Canada. We had a few more that we were able to treat in theatre, and those soldiers returned to duty. But that is a pretty significant low rate compared with what some of the scientific and theoretical texts have out there.
