The American military has two main jobs now in Afghanistan: sweeping the remaining Taliban from safe havens and getting Afghan security forces to take charge in the fight.
On a recent day, the Afghan National Army, or ANA, is to be out front on a joint Afghan-U.S. patrol in the countryside outside Kandahar in southern Afghanistan. It may seem like a small thing, but it's actually a big deal.
Sgt. Matthew McMurray lets his platoon know.
"ANA is going to lead, too. If they don't want to lead, just stop and make them walk ahead of you," he says.
