Im pretty sure im around the same age as you Troy and grew up with roughly the same things.
I was able to play any game as a kid like drug son of rajab 2, gta, call of duty ect doesnt make me desensitize by the violence, it allows me to know right from wrong.
Being a parent and ex defence I have a rough idea on what issues come with both jobs/tasks.
Its not easy and it affects each person differently. I've been through courses with people who say loses a love one overseas and see how they cope.
You just have to be there for them and give them any help that is possible.
No one knows the answers or makes the right decisions when they have to but its what you learn from them.
I think we all need to get together and have a BBQ so we can all relax.
p.s wait till i get my car back lol
