I'll answer starting with the sense of community. The greater the community is, the stronger the connections are. Studies show over and over an improvement or strengthening of mental health and a decreased risk of suicide. In the countries I mentioned, there's a larger, communal culture. Bringing the families in is very important. The member doesn't exist without the family.
In my experience, or with respect to my brother, this wasn't the case. In fact, the level of communication that came.... Other than the designated assistants and the chaplain that were assigned to support my sister-in-law, there wasn't any further communication. The transition centre didn't engage our family. It took me close to a week to hunt down my brother's body. No one could tell me where it was. It was me hunting it down; it wasn't the department.
The military family resource centre is there in title. It's small. Funding for these organizations has decreased over time. The element of community and funding services that bring family members closer into the community would be very helpful, but it has decreased over the last decades. I've seen it slowly deteriorate with strategic reviews, with budget cuts and with our reality.
