WASHINGTON (AP) — Vice President Joe Biden is paying tribute to what he calls a "9/11 generation of warriors."
Speaking at the Pentagon today to mark the 10th anniversary of the attack that heavily damaged the defense headquarters, Biden said, "Never before in our history has America asked so much over such a sustained period of an all-volunteer force."
He said the "9/11 generation ranks among the greatest our nation has ever produced."
Defense Secretary Leon Panetta observed a moment of silence at 9:37, marking the time a jet struck the Pentagon 10 years ago. He paid tribute to the 6,200 members of the U.S. military who have died in the Iraq and Afghan wars.
President Barack Obama is expected to visit the Pentagon later, after returning from New York and Shanksville, Pa.
