Alex Hohl came back to his family home in Framingham, Massachusetts, last Saturday, from his second tour in Afghanistan with the Marines.
"It's incredible, it's something you can't describe," he says.
He also shares his thoughts and feelings about his fallen buddies.
His mother, Patricia Hohl, is happy, too, but concerned.
"My husband and I are only just realizing, after this more dangerous tour, just how much support we're going to have to give him. Alex hides things well."
