Troops grapple with new challenges in Afghan offensive

American, British and Afghan troops have entered day five of a major offensive in a Taliban stronghold in southern Afghanistan. While the offensive is largely going to plan, troops on the ground are dealing with far more than just encounters with Taliban fighters. The accidental killing of 12 civilians in Afghanistan in recent days has troops bringing condolences to the families of the victims.

Meanwhile, improvised explosive devices (IEDs) continue to pose one of the biggest threats to troops. For a look at the challenges faced by troops on the ground, we turn to Rod Nordland, New York Times correspondent in Kabul, along with Ret. US Army Col. Jack Jacobs.
