Earlier this year, NPR's Tom Bowman reported on the high casualty rates experienced by the 3rd Battalion, 5th Regiment of the Marine Corps — the Darkhorse Battalion. This was during their deployment in one of Afghanistan's southern provinces. Morning Edition reached out to a member of that battalion who is home for Christmas this year. Renee Montagne talks to Staff Sgt. James Foley, who joined us on the phone from Camp Pendleton in Southern California.
