Marine Master Sgt. Robert Allen sings a song he wrote for his wife for Christmas. Allen joins the thousands of men and women deployed this holiday season in support of counterinsurgency efforts in Afghanistan. He said he hopes his Christmas song “will help people understand that though we’re willing to do it, it’s still heartbreaking.” Master Sgt. Robert Allen, Hometown: Pawnee, Okla. Produced by Cpl.
