Naval career
Song was originally accepted to the Navy pilot program in college, but had to change after being deemed too tall at to operate planes and helicopters in the field. His job path was then changed to a Naval flight officer and flight mission commander, serving on helicopters. Song was originally scheduled to report to Naval Air Station Pensacola on November 1, 2019, to start training as a naval flight officer and begin his five-year commitment to serve, until he was selected to play for the United States nationalbaseball team at the 2019 WBSC Premier 12 tournament during November 2–17. After the tournament, he was scheduled to report to flight school in Pensacola in December 2019. In December 2019, Admiral Robert P. Burke, Vice Chief of Naval Operations, denied Song’s petition to delay his active service time, requiring Song to attend flight school and delay his professional baseball career. Basketball player David Robinson, the first overall pick by the San Antonio Spurs in the NBA in 1987, served in the Navy for two years before embarking on his Basketball Hall of Fame career. Acting Secretary of the NavyThomas Modly, along with Defense Secretary Mark Esper, could grant Song a waiver—against Admiral Burke's recommendation—but a Navy spokesperson said that no final decision had been made. In June 2020, it was reported that Song had received orders to report to flight school in Pensacola by June 26. Song would be able to apply for early release from his training in May 2021.
