I do not agree with your thoughts on this, as PTSD, or “shell shock” was a big item with WWI vets. It’s actually where studying of this phenomenon got started where the name changed to combat stress and now PTSD. As a young boy a WWI vet neighbor would scream all night long with his nightmares.
To me the cure for it is to not send premature men into combat. What I’ve learned is the human brain is not fully matured (or wired) until age 25. Whatever goes on prior to that becomes a part of permanent wiring.
If a young 18 - 21 yo boy is stressed to the absolute limit day after day in fear of his life, he will take on permanently certain personality traits for the rest of his life.
My opinion, keep in mind opinion, is to send only 25+ year olds into combat.
In the Civil War it was called Soldiers Lament.
Unfortunately warriors in the main are young either in age or emotionally.
The point is regardless of age sending to fight in wars without victory only increases the problems they have from the trauma of war itself.
But thanks for your opinion as well.
