BEULAH (AP) - The father of a Marine injured in a grenade attack in Iraq says his son wants to complete his mission there.

Cal Wagner said his son, Lance Cpl. Robbie Wagner, 22, suffered shrapnel wounds to the right side of his face, shoulder and forearm, and right hip areas when enemy grenades were thrown at him and three other Marines on foot patrol April 2.

Cal Wagner said Marine Corps officials told him his son was being treated at a medical facility at Ar Ramadi, Iraq, and that he was doing fine.

Wagner said he told Robbie he wished he could come home but his son said, "No Dad, our mission isn't complete over here. I need to be here yet."

Cal Wagner said a Marine spokesman at Camp Pendleton, Calif., told him his son had three small grenade fragments to his right cheek, three to the hip and 12 to the right shoulder and forearm.

"Everything was removed and there probably won't even be any scarring, except maybe the three on his hip," Wagner said.

"The only thing the Marine Corps spokesman told me is with this type of wound they watch for infection, and if there's no type of infection, he's probably back out with his unit already," Wagner said.

Yet, every time his phone rings, Cal Wagner said he crosses his fingers, hoping it's his son on the other end of the line. He talked to Robbie last Saturday, the day after the attack.

"When I talked to him, he said, 'Dad, don't worry, I'm going to be fine,"' Cal Wagner said.

Robbie Wagner, who works in reconnaissance, is stationed with the 2nd Battalion, 4th Marines in the Ar Ramadi and Fallujah areas in the Sunni Triangle. "That's a hell hole right now," his father said.

"He's only been in Iraq since February so he's just part of the rotation that just got there. But he's just starting his fourth year with the Marine Corps," Cal Wagner said.

Robbie Wagner is a 2001 graduate of Beulah High School. He left for the Marines just five days after high school graduation, his father said.

Robbie was home on leave for Christmas. His father said Robbie feels the Marines are doing a good job in Iraq, though he sounded tired and stressed.

Cal Wagner said his son told him: "Dad, I need to be with my brothers - our mission's not complete."
