Bomb-sniffing dogs "have been used more than ever" since 9/11, reports "60 Minutes'" Lara Logan, "because nothing has proven more effective against hidden bombs than the nose of a working dog."
The news program offered a rare glimpse into the training of the elite dogs on Sunday, interviewing
Green Beret Chris Corbin and his dog, Ax, who led their unit through a battlefield filled with hidden bombs in Afghanistan.
Corbin says that the dogs feel "invincible."
"We don't train them to fail," he told Logan.
