The defense debate tends to treat Afghanistan as either a revolution or a fluke: either the "Afghan Model" of special operations forces (SOF) plus precision munitions plus an indigenous ally is a widely applicable template for American defense planning, or it is a nonreplicable product of local idiosyncrasies. In fact, it is neither. The Afghan campaign of last fall and winter was actually much closer to a typical 20th century mid-intensity conflict, albeit one with unusually heavy fire support for one side. And this view has very different implications than either proponents or skeptics of the Afghan Model now claim. Afghan Model skeptics often point to Afghanistan's unusual culture of defection or the Taliban's poor skill or motivation as grounds for doubting the war's relevance to the future. Afghanistan's culture is certainly unusual, and there were many defections. The great bulk, however, occurred after the military tide had turned not before-hand. They were effects, not causes. The Afghan Taliban were surely unskilled and ill-motivated. The non-Afghan al Qaeda, however, have proven resolute and capable fighters. Their host's collapse was not attributable to any al Qaeda shortage of commitment or training. Afghan Model proponents, by contrast, credit precision weapons with annihilating enemies at a distance before they could close with our commandos or indigenous allies. Hence the model's broad utility: with SOF-directed bombs doing the real killing, even ragtag local militias will suffice as allies. All they need do is screen U.S. commandos from the occasional hostile survivor and occupy the abandoned ground thereafter. Yet the actual fighting in Afghanistan involved substantial close combat. Al Qaeda counterattackers closed, unseen, to pointblank range of friendly forces in battles at Highway 4 and Sayed Slim Kalay.

In 1950, when he commissioned the first edition of The Armed Forces Officer, Secretary of Defense George C. Marshall told its author, S.L.A. Marshall, that "American military officers, of whatever service, should share common ground ethically and morally." In this new edition, the authors methodically explore that common ground, reflecting on the basics of the Profession of Arms, and the officer's special place and distinctive obligations within that profession and especially to the Constitution.
