The problem with threads like this is that there are many opinions based on anecdotes and pronouncements. There is quite a bit of study of this. One should use Google scholar and read some of the literature.

1. People who deny it happens outright are incorrect. If they state people who do get stress disorders are weak - they do no service to their professions. If it is through ignorance or bravado - who cares. They are wrong. I know of cases of folks who have impeccable credentials and then in force on force training later have a stress related incident or flashback to some previous action.

2. No, it doesn't happen to everyone. Numbers vary. We can't predict who will be at risk with enough certainity at the present time.

3. If you don't get it - it doesn't mean you are disordered either. Some small percent of folks without remorse may be but it isn't everyone.

4. Great point that folks should be educated before! Stress innoculation and knowing how to be aware of symptoms is a great step forward in critical incident education. However, I will disagree that preparation can give you a guarantee of immunity. As in all things, it can help but an absolute guarantee you get it or don't - doesn't exist. But training is essential.

5. Changing the mindset so those that need help will get is also a great step forward for folks involved in critical incidents.

6. Knowing what treatments are efficacious is also important. There are crackpots out there.
