She's the one who breaks the news to soldiers’ families that their heroes won't be coming home. With one of the most difficult jobs in the Army, Chaplain PK Roberts, whose job to support military families, is about to get even more personal.

She joined the Army to serve God and her country. “I’m blessed to be called by God to do what I do and that's to provide ministry for soldiers and their families," says Chaplain Roberts.

On Sunday, you can find her preaching at the chapel inside Evans Hospital on Fort Carson. That comes easy for her, but what’s most difficult is doing death notifications.

She says, “I get called by the casualty office to assist a non-commissioned officer to carry the news that one of our soldiers was killed in action. The thing that's most painful for me is walking up to that door knowing that in most cases, the person who opens the door and sees me standing there in my Class A uniform, that the news is not going to be good."

"The one case that surprised me most was when before we could give the news, the mother fell on the floor and refused to wake up to hear the news. She just refused to wake up," says the chaplain.

Chaplain Roberts says every time she walks away, she carries survivor's guilt. “When I make a death notification to a mother or a father and I leave, my question has been, ‘God, why not my son? How is it that he has survived three deployments to Iraq?’"

Her 32-year-old son, Sgt. Elijah Roberts Junior, followed in his mother's footsteps. He joined the army seven years ago. Now, Chaplain Roberts' only son is about to deploy to Afghanistan. He's doing what he loves to do for this country… I have to keep telling myself that."

She prays that she never gets that knock on her door, but Elijah told her if it ever does happen, “We love doing what we do, just like you, mom. If ever you are notified, you got to know that I do what I love to do, what I was called to do. Hearing that helps me do my job," says Chaplain Roberts.

While her job is to be a soldier's mother and a chaplain, she remains courageous in the face of war.

Her son is stationed in Germany. He's expected to deploy early next year.
