A program in Southern Arizona assists injured soldiers, who are medically retired from the military, through their recovery process.

In 2007, Reno Roethle was driving a truck outside Sadr City, Baghdad, when an improvised explosive device exploded right next to the road.

Roethle - of the Army 82nd airborne division - said his "vehicle was penetrated with shrapnel and I got hit in the side of the face."

Today, he bears the scars of that explosion.

The IED took out part of his jawbone, severely lacerated his cheek and left him suffering from PTSD.

His injuries were severe enough that he was medically retired from the army.

Roethle turned to the Army Wounded Warrior Program, or AW2, to help him transition from military to civilian life, while living with both the trauma and the scars leftover from his time serving in Iraq.

Michael Dow, who is one of the 2,000 army advocates around the country, said AW2 is the "army's official program to help its most severely wounded, ill and injured and soldiers."

Most advocates have a caseload of between 40 to 100 medically retired soldiers.

Dow's caseload is at the high end, with 100 wounded army veterans under his care.
