Harry said what the wounded veterans have been through mentally can take them to a whole new level.
"No matter what you can progress in your life," said Harry. "These guys before they were wounded, they were never planning on going to the North Pole."
The prince joked about the frigid weather with Woodruff. "I think i acclimatized last night, hopefully, but I think this butt is stuck to this railing," he said.
Harry will only be with the group for the first five days of the journey; he has to return to London to prepare for the wedding.
Prince Harry also talked about his upcoming training to fly Apache helicopters .
"It is like flying a robot. It's one of the safest helicopters, hence my father wasn't too upset when I was selected for it," he said.
Harry said training to fly the Apache suggests that he would be assigned to a combat area in Afghanistan. The last time he was deployed, he had to be taken out of the war zone after his presence became public for fear that he would be targeted by the Taliban.
But training to fly an Apache is "very, very expensive," he said and "they wouldn't have me doing what I'm doing.... if they didn't have me set on doing a job."
The prince will be coming to America for part of his training.
