If Col Vail is the son of Gen Vail he's nothing like his dad and that's bad for the Troops.
Political catastrophe... death and injury, sadly, are the only means of creating evidences.
In other words, while terrorists invent evidences of us harming them by their lethal "retaliations" and beheadings, we just stop them and let them go, them and the evidence that anything happened or anything is going on.
Non lethal weapons are one of those devilish socialist inventions and late promotions and "assymetricalizing" warfare against us
But it will not stop their love for death and their helplessness.
