United States Marine Corps TV Commercial, 'Battle Up'

Ever since she was little, this girl exhibited the fighting spirit. Whether she's intervening to stop bullying, fighting her way through a drenched rugby field in the pouring rain, trying to stay above water in boot camp or staying on the front lines, she continually sheds her old skin and emerges stronger than ever. Nobody knows where this spirit comes from. The U.S. Marine Corps says people like her will be necessary as long as there remains a battle to fight.
