Micheal Yon writes about this as he heads out with our troops. Reading the whole thing is Recommended.
...In the short time since Petraeus took charge here, Anbar Province – “Anbar the Impossible” – seems to have made a remarkable turnaround. I just spent about a month out there and saw no combat. I have never gone that long in Iraq without seeing combat. Clearly, some areas of Anbar remain dangerous—there is fighting in Fallujah today—but there is also something in Anbar today that hasn’t been seen in recent memory: possibilities. There are also larger realities lurking up on the Turkish borders, but the reality today is that the patient called Iraq will die and become a home for Al Qaeda if we leave now.This attack is code-named Operation Arrowhead Ripper.
...Northeast of Baghdad, innocent civilians are being asked to leave Baquba. More than 1,000 AQI fighters are there, with perhaps another thousand adjuncts. Baquba alone might be as intense as Operation Phantom Fury in Fallujah in late 2004. They are ready for us. Giant bombs are buried in the roads. Snipers—real snipers—have chiseled holes in walls so that they can shoot not from roofs or windows, but from deep inside buildings, where we cannot see the flash or hear the shots. They will shoot for our faces and necks. Car bombs are already assembled. Suicide vests are prepared.
The enemy will try to herd us into their traps, and likely many of us will be killed before it ends. Already, they have been blowing up bridges, apparently to restrict our movements. Entire buildings are rigged with explosives. They have rockets, mortars, and bombs hidden in places they know we are likely to cross, or places we might seek cover. They will use human shields and force people to drive bombs at us. They will use cameras and make it look like we are ravaging the city and that they are defeating us. By the time you read this, we will be inside Baquba, and we will be killing them.
