Woodruff and his crew had been traveling in a U.S. armored Humvee, but then transferred into an Iraqi vehicle -- which was believed to be a much softer target for attacks.
"It was a mechanized vehicle," Raddatz said. "At least it wasn't one of the pickup trucks they usually drive around in. They were in the lead vehicle, and they were up in the hatch, so they were exposed."
Raddatz said both Woodruff and Vogt were protected. They were wearing body armor, helmets and ballistic glasses. Woodruff and Vogt were taken by medevac to the Green Zone to receive treatment within 37 minutes of the blast. They were then flown by helicopter to Balad which is about a 20-minute ride from Baghdad, said Raddatz.
"There are very good doctors, the best medical care you can possibly get, in Balad," said Raddatz.
Training Iraq forces to deter insurgent attacks has become a central focus of U.S. strategy toward ultimate troop reduction and withdrawl. Journalists must travel with Iraqi troops to truly cover the conflict in Iraq, but doing so makes them more vulnerable to attack.
"If you're going to cover the Iraqi military forces, you have to be with them," Raddatz said. "You have to see how they live. I will tell you one thing, a few months ago when I was there and we wanted to get into an Iraqi pickup truck, one of the American soldiers said, 'You can't do that. It's way too dangerous.' "
Iraqi security forces, Raddatz said, are a softer target for insurgents.
"It's become a primary target. It's a softer target, as you know, but it is a primary target to attack these forces," Raddatz said. "There have been hundreds and hundreds -- thousands, probably -- of Iraqi security forces killed. Sometimes they're attacked by suicide bombers, but they have become a primary target. It is very dangerous business training these troops, for that reason alone."
But Woodruff and Vogt knew this and were very careful.
"I have worked with Doug Vogt so many times. He is no hot dog. Bob Woodruff would not take risks that were -- without his body armor or anything else. They are both very careful. Doug, as a matter of fact, when he was with Terry Moran a few months ago, they hit a very small IED, and one of the Iraqi forces was killed. Doug was also in that convoy, but he was in an armored humvee at that time."
IEDs have accounted for more than half of all U.S. military injuries in Iraq and are the single greatest cause of death of service members.
As of January 21, 2006: 9,282 of 16,548 injuries were caused by IEDs. At least 894 of the 2,242 deaths in Iraq have been from IEDs.
The number of IED attacks on U.S. and coalition forces on Iraq has nearly doubled since 2004. But there have been fewer overall IED-related deaths and injuries.
Each deployment of soldiers has learned how to become more aware of IEDs, protective quipment has become more hardened, and commanders. In addition, commanders have learned how to best move troops around a battle space in ways intended to limit the effectiveness of IEDs.
Along with Elizabeth Vargas, Woodruff, 44, was named co-anchor of "World News Tonight" last month, replacing the late Peter Jennings, who died of lung cancer last year. Woodruff has been on assignment in Iraq and planned to broadcast from the war-torn country this week for the State of the Union address.
