Pfc. Joseph P. Dwyer was photographed recently as he carried a child to safety in a battle zone. The photo has been widely published, and in this Army Times story it turns out he enlisted after learning his brother didn't die in the Twin Towers. Army Times:

The soldier in the picture, Pfc. Joseph P. Dwyer, 26, is still in the field, about 80 miles outside Baghdad with his outfit in the 3rd Infantry Division. [He was misidentified by a superior in the field and in the original caption.] Until today, he hadn’t a clue that he was famous. His reaction when he found out?

He laughed. And couldn’t stop laughing. He was both amused by this and embarrassed. “Really, I was just one of a group of guys. I wasn’t standing out more than anyone else,” he said in a telephone conversation during some rare down time.
