Iraq Now leads us to this very informative technical article giving the nuts-and-bolts of "how to fight and win in Iraq":

American soldiers are facing men with a cell phone is one hand, a RPG in the other, and ill-conceived hatred in their heart ... Technology only enhances the soldiers’ capabilities to kill the enemy and win their hearts and minds simultaneously. In the end, US soldiers must meet the enemy — specifically terrorists — face-to-face, hand-to-hand and kill them. Company commanders must bring to bear creativity, aggressiveness, and an offensive spirit to take away the enemy’s will. In the end, gather information on enemy targets and then narrowly target them with overwhelming combat power.

Which is very much what most company-level commanders were saying about Vietnam for years. The difference, it would at least seem, is high command is listening this time. (In fact, Hackworth's recent column seems to back this up.)
