There's a piece of advice somewhere in there...
"Be prepared to go 12 miles a day with a ruck and do it day after day." (p.4-6)
Nothing says you can't increase the times or the distances if you're in better shape.
JJ Thanks for the recommendation. Best place to buy GET SELECTED is here:
www.specialops.org ...or ask for it at your local Clothing Sales or PX.
You can find it on Amazon, but you'll pay more for it.
