Not going to touch on the military boarding issue, but I'm guessing a military bus is far different boarding-wise - I doubt you have servicemen/women constantly taking an aisle seat, then standing up and letting someone else slide in to the window.
W-M-A has been documented / proven / studied as more efficient than back to front by rows.
