I would like to add that there is a network within the regiments. This basically concerns the army. They have appointed first contact people, such as senior non-commissioned officers, or people with some seniority, to identify behavioural changes in young soldiers. They are identified from very low in the chain of command.
Culturally, I also believe that there is more recognition that soldiers can suffer psychological injuries. Military leaders are aware of this risk, and there has been great change in this area. So, people probably speak more freely.
