Amerifag vet here so I can't speak for the ADF but our service seems to have the same problems. Veterans have problems with relationships, drinking and jobs.

Pro;
Confidence in myself is solid, I know how far I can run and how high I can jump. I fear no physical combatant and find myself being much more aware of the world around me than most non military.

Con;
I drank for a whole year when I got back from my tour and I've had other substance abuse issues even after getting a handle on drinking. I really didn't even see anything to bad either, comparatively. What I have seen though separates me from most of my peers. I've been at parties where people wonder aloud what it's like to see a dead body. I know. I'm not saying that to be dramatic but it's that for every aspect of military life from knowing that 5.56 buzzes and a 7.62 cracks as they fly past your head. Once you see it you can't unsee basically.
