The Hill brothers serve on the Rear Detachment (Rear D) unit, comprised of the soldiers left behind when everyone else is deployed, because they're not quite good enough to be sent overseas, yet not bad enough to be kicked out of the Army. These are the men and women who mow lawns at the base, sort mail, wash tanks, find lost dogs and maybe engage in a war game or two. But the Rear D's main job is taking care of deployed soldiers' families. Whatever they need, the Rear D soldiers do. And, in the event that something happens to a soldier overseas, the Rear D troops break the news to the family and become a supportive shoulder to cry on. It's a job that shifts each moment from the thrilling to the mundane to the emotional and back again.
