What did Major Gregory "Pappy" Boyington achieve during WWII?

Major Gregory "Pappy" Boyington is renowned for his exceptional performance as a fighter pilot during World War II, particularly for his command of the "Black Sheep Squadron." He achieved notable success in aerial combat, famously accumulating 28 confirmed aerial victories, which significantly contributed to the U.S. military's air superiority in the Pacific theater. His remarkable achievements in aerial dogfights led to his being awarded the Medal of Honor, one of the highest military honors.

The other options do not accurately reflect Boyington's historical contributions. While he was an influential figure, he did not command a Marine division, nor was he a participant in the Battle of Tarawa, which involved other key military leaders and units. Additionally, Boyington was not a Code Talker; that role was specifically filled by Native American Marines who used their languages to transmit secure communications. His legacy is primarily tied to his aerial prowess and leadership in the Marine Corps during the war.
