Probably, there is a old TED talk by Thomas Barnett [1], where he argues quite similarly. He argues, that one needs a force for projection of force and a force for stabilizing the country. And because of the tension between trying to be as small as possible, when defeating the opponents army, and the need for boots on the ground for defeating insurgents these two need very different organizational structures.
