True leaders prepare their soldiers for war.
The CF did a horrible job at that (I would assume still does - but I am long stale for that comment to have 100% accuracy ) - as do most Militaries outside of their SOF. In the same vein that most LE and other first responders do a piss poor job of preparing their members for emotional trauma.
Proper mental training, effective and realistic training would do a heck of a lot more do reduce issues of CSR/PTSD.
As opposed to a bunch of BS bravado in training that does nothing for downrange effects.
Education into what the body and mind do under stress, and giving member the tools and conditioning to function during and after critical incidents is going to pay off a whole lot more than soley dealing with issues after the incidents.
Proper counseling after issues helps, and not some half baked counsellor - but real professional mental health specialists who specialize in the specific area of trauma.
