Very nice personal interview with Sgt. Pereira here at TIME which is well worth watching.
From Army News Service via Blackfive:
While suffering from a partially collapsed lung due to shrapnel wounds, Pereira rescued other injured Soldiers caught in an ambush in Kandahar Province, Afghanistan, Nov. 1, 2010.
Pereira is a dual citizen of Brazil and the United States. He will become the first 101st Airborne Division Soldier since Vietnam to receive the Distinguished Service Cross, the second-highest award for valor. He is assigned to Company A, 1st Battalion, 502d Infantry Regiment (Strike), 2nd Brigade Combat Team, 101st Airborne Div.
Pereira's citation reads: "His dedication and commitment to duty undoubtedly saved the lives of two of his fellow Soldiers, while his leadership and distinguished service were instrumental to his unit's successful response to a lethal attack."
