When my son was with the 82nd ABN (MOS 18B = hunt, kill, eat, sleep, poop, repeat) they brought them inside the wire to Kandahar or such to cool off for 30 days prior to returning to the US. So where they are getting this 24 hour business I don’t know.
He is still in, but is now with the 1st SF Group.
In my observations it was the men that had set goals for when they came back that did well. They were also the ones that either were, or became, team leaders, etc. It was the ones that came back without goals and just hung around the barracks, went out drinking, etc that did not do well.
I think the OP is about Canadian soldiers.
I had a string of SpecOps guys through our home all on R&R from the Sandbox. This was over the first ten years of this war. I agree, the ones that came back with some definite goals and things they wanted to accomplish did better both in the short term and the long term. We did everything we could to help them on their quest. Lost two out of about 75 - KIA and several wounded. That said I spent many a late night talking with many of them. These guy were mostly tier 1 and were buddies with my son. Several couldn’t wait to get back and get some; very mission driven and dedicated.
Good news is that all have left the Military and moved on in life. Gotten married and are having kids. Thankfully none have committed suicide. We consider ourselves to be very lucky to have enjoyed the company of these heroes and we remain close to a few to this day seven years later.
