Williams likely would have exceeded 600 career home runs if he had not served in the military, and may have even approached Babe Ruth's then record of 714. He might have set the record for career RBIs as well, exceeding Hank Aaron's total. While the absences in the Marine Corps took almost five years out of his baseball career, he never publicly complained about the time devoted to service in the Marine Corps. His biographer, Leigh Montville, argued that Williams was not happy about being pressed into service in South Korea, but he did what he thought was his patriotic duty.
