LTG Petraus is credited with stating "Generals set tone."
The GOs that will work for him will pay signigficanly more attention to the value of non-kinetic operations and weighing the vallue of kinetic opertions before launching them.
The question is how long will it take to filter down to the Squad Leader level?
I know one General who personally lost 30 pounds just to "remodel himself" before taking command. I suspect it put him in the image of Petraus...but who knows...
