Why isn’t Jones in line with McChrystal?
My 'guess': McChrystal is a career Special Forces officer and Jones is a 'Leg'.
'Legs' hate SF, don't believe in Special Operations and still want to 'charge' into battle with an Infantry Division and Tanks in a nice straight line.
note: Jones may sport Jump Wings and an Airborne Patch - means nothing. Many 'Legs' do that just to get their ticket punched.
Your comments fit with my layman's view that he looks to be a major league politician in his visage. I don't know how the folks on the ground feel about his having their backs, I would not know.
