Description:Chuck Hagel, fresh from a fractious confirmation process and now on his first day on the job as U.S. secretary of defense, told military and civilian staff at the Pentagon on Wednesday (February 27) that he will do all in his power to be a worthy leader of the nation's military. "It's a privilege. Yes, for me, my family, but to be part of your team, who you are is the honor. That's the great privilege. You're not joining my team; I'm joining your team," Hagel said.(1:28)
