Instapundit linked up this in-depth analysis of developing strategies and tactics in what is now being called "Operation Iraqi Freedom II":

In OIF II, as it is called in the military ranks, American forces face an enemy employing classic insurgent tactics: ambushing American troops on the roads, intimidating fledgling Iraqi security forces, assassinating Iraqi government officials and terrorizing the population with random car bombings. There have also been pitched battles in cities, including two in Fallujah. But, led by those doing the fighting and the dying, American forces are learning some critical lessons about employing new tactics and new technology. These hard-won insights may influence how long the insurgency will last and how the United States will fight in future conflicts.

The article goes on to detail an extremely positive feature of this conflict... the empowerment of the "strategic corporal." One of the few things nearly everyone agrees contributed to the debacle of Vietnam was the concentration of authority at the highest levels. Johnson picking targets from the Rose Garden, rules of engagement so rigid targets had to be tracked for hours before they were "legal" to hit, that sort of thing. By giving authority to those closest to the action and most familiar with the situations on the ground, we go a very long way to ensuring the right decisions are made, the right force applied, and the right people removed.

Which is, of course, how wars are won.
