We move materiel based on the operational necessity, so there will be times—if, for example, we need to get equipment parts, food or additional resources to deployed troops—where we might have to rely on commercial means if that's going to be quicker than what we refer to as the “national freight run” or the green trucks to move our equipment.
We assess the criticality of the operational requirement and the imperative to get it into the hands of the men and women who are serving on behalf of the nation as we make these determinations.
