His 3rd (of 4) Bronze Star Medal w/Valor Citation reads:

For heroic achievement in connection with combat operations in support of Operation ENDURING FREEDOM on 17 March 2010. On this date, Petty Officer First Class Bill was part of a ground force element during a daring nighttime raid against a heavily armed enemy commander. While attempting to engage a barricaded fighter hidden inside the target building, one of his teammates was struck and mortally wounded by enemy fire, causing him to fall directly in front of the barricaded enemy's position. With complete disregard for his own safety, Petty Officer First Class Bill fought his way into the compound, exchanging fire with the enemy fighter while maneuvering to his wounded teammate. Within point blank range of the barricaded enemy, Petty Officer First Class Bill pulled his comrade from the precarious position where he had fallen as enemy rounds impacted the rock wall around him. He then courageously exposed himself to the enemy fire again, as he pulled his wounded teammate across the open courtyard to a position behind cover. By his extraordinary guidance, zealous initiative, and total dedication to duty, Petty Officer First Class Bill reflected great credit upon himself and upheld the highest traditions of the United States Naval Service.
