I have a love of hiking. I have wanted to be a hiker for years. Still not there. Love to do it but am not "good" at it. I subscribe to Backpacker to pick up tools to make it easier on me. I love the military too and so this article hit home for me in both of my loves - hiking and the military.
May 2013 had an article that I just read through and through. It is called All Quiet on the Western Front. Please forgive their HORRIBLE website but read through the article.
CONCLUSION: This is exactly why the BSA uses the outdoor as part of their program. It gets you away, it gets your head clear, it provides a physical challenge to the body making it stronger and tougher which results in a clear head, a return to basics, etc. I could go on and on about extended hiking trips. I wish there was a way to do it as an LDS unit(s).
