As if to dispel all speculation over an operational pause, U.S. Marines and 3rd Infantry Division units had punched through Iraqi lines at Kut and Karbala and charged hard northward, reportedly bringing their forward positions to within 4 miles of the city limits. "The dagger," said Brig.-Gen. Vince Brooks at Wednesday's briefing in Qatar, is "clearly pointed at the heart of the regime."

CNN.com: War in Iraq
The coalition's current objective appears to be "degrading" the heavy Iraqi units defending the approaches to Baghdad through a combination of around-the-clock bombing of armor and fortifications, and ground assaults backed by further air power. At the same time, intensive bombing of targets in the capital continues, focused on destroying the regime's lines of communication. U.S. Special Forces have also reportedly conducted raids inside the capital, including one on a presidential palace.
Despite the proximity of the 3rd Infantry and the 1st Marine Expeditionary Unit to the capital, however, it's not clear that coalition forces plan to launch an assault on Baghdad for weeks yet. They're focused right now on attacking heavy units deployed around the capital, but the limited resistance encountered in Wednesday's advance suggests that at least those elements that survived the heavy bombing may have dispersed into smaller, lightly armed but more mobile units or retreated towards the capital. Conflicting reports Thursday suggested some Republican Guard units may be heading south to confront the U.S. forces outside the city, while others suggested many such units were retreating into Baghdad.
The Iraqi defensive concept appears to have relied heavily on guerrilla tactics until now, and spokesmen insist their strategy has been to treat the entire campaign as a battle for Baghdad, hoping ultimately to stop the U.S.-led campaign in the densely-populated streets of the capital even as they continue to harass coalition forces all along the road from Kuwait. Republican Guard's tanks, APCs and heavy artillery pieces are no match for the equipment of the U.S. ground forces, and are easy prey for U.S. air power. One explanation for Wednesday's comparatively easy advances may be that U.S. air power had so pummeled the Iraqis that they were no longer able to mount effective resistance; another is that Iraqi units may be dispersing in smaller units and retreating into the capital.
The crucial question remains how, and when the coalition forces might try to enter Baghdad to deliver the knockout blow to Saddam's regime. Currently, U.S. troop strength on the edge of the capital appears too limited to launch the final battle. Analysts have speculated on whether U.S. commanders will wait to swell their numbers following the deployment in Iraq of the 4th Infantry Division, which was to have provided the northern flank of a drive on Baghdad before Turkey pulled the plug. The 4ID has now landed in Kuwait, although acclimatization and marrying them up with their equipment may take up two weeks.
The Iraqis are relying on the political restraints on coalition forces to even up the terms of battle in Baghdad. Out in the open, U.S. air power makes it no contest, but the coalition's need to avoid inflicting civilian casualties negates many of its advantages in a street-by-street fight for the capital. Baghdad is easily accessible for armor perhaps in order to make the city's residents more easily subject to the control of his own military, Saddam built a series of six-lane highways that snake into the center of the capital. But its 5 million residents are densely concentrated in small, single and double-story houses with walled-in gardens, and fighting street by street will force the coalition forces to inflict (and perhaps suffer) significant casualties. And if the fighting by irregular forces is as fierce as some seen in southern Iraq in the past two weeks, the going could be slow and bloody. Rather than a grinding fight to take control of all of Baghdad, coalition forces may simply go for the jugular by driving into the area from which Saddam's leadership is operating. But the Iraqis may have anticipated such a scenario, and spread their command structures throughout the city.
One fear confronting U.S. commanders is the possibility that Saddam's forces may unleash chemical or biological weapons now that coalition forces have crossed the "red line" that puts them in range of the most likely delivery systems. But at this stage of the battle, such weapons would almost certainly kill far more of Saddam's own forces than they coalition forces better equipped to respond, and would unlikely have much tactical impact on the battle and their use would help the coalition's battle for international public opinion. Right now, the Iraqis appear to be preparing for a siege of Baghdad, hoping that the resulting humanitarian crisis the already mounting toll of civilian casualties will turn the political tide against the coalition. The immediate coalition objective is to destroy Iraqi divisions deployed south of Baghdad before they can retreat into the capital. Beyond that, however, the shape and timing of the inevitable assault on Saddam's center of power remain an open question.
