. . . but I think I have my Man of the Year already. From the Algemeiner:

A former US Army Staff Sergeant who lost both legs while serving in Afghanistan is heading to Israel as a volunteer for the IDF.
Brian Mast served his country for twelve years before the catastrophic injury cut his career short. Now a full-time student at Harvard University, Mast said his decision to travel to Israel was partly triggered by the anti-Israel demonstrations he witnessed on campus.
“This past summer I was there studying,” Mast told website Western Journalism. “At the same time, I saw the anti-Israeli protest in the face of the attempted indiscriminate bombardment of Israel. It was then that I decided I needed to find a way to go help however I can and however Israel would have me.”

One more paragraph from this extraordinary article:

Mast, who grew up in a Christian home in South Florida, said that his parents had impressed upon him the importance of the US alliance with Israel. He remains intensely committed, he added, to promoting “liberty and freedom from tyrannical regimes.”
