 Pentagon officials offered the most detailed look yet this week on how the military plans to carry out President Obama's ordered drawdown of American troops in Afghanistan. Some 800 Marines from 3rd Battalion 4th Marine Regiment will head home sometime this fall as part of the first 10,000 troops ordered home by year's end. The president wants a third of the 100,000 service members in the country to come home by the end of next summer. While going deputy commander of U.S. forces in Afghanistan, Army Lieutenant General David Rodriguez said American troops have begun working themselves out of the job there. But he cautioned that violence is not expected to subside anytime soon. The U.S. plans to shift its focus from the security gains made in Afghanistan's southern region to the east along the Pakistani border. From Washington, I'm Sergeant Todd Hunter.
