One of the abilities most lacking in the US military right now is the ability to ruck- hike with a loaded back pack. I know plenty of guys who can run fast and are very strong, but just can't maintain a decent pace under load. It's a hard one to train as well, because there's nothing to do but put in the time with the ruck.
