Team USA may soon have to do without the services of LeBron James, but they may have found his replacement at Thursday’s USA Basketball Showcase in Las Vegas, thanks to an incredible dunk by United States Air Force Airman Nathaniel Mills.

During a break in television coverage of the USA Basketball showcase, Airman Mills walked onto the court in full military regalia, including a uniform and combat boots, Yahoo Sports reports. Mills proceeded to grab a basketball and throw down a thunderous, one-handed “windmill” dunk, receiving an ovation from nearly 10,000 Las Vegas fans.

Airman Mills was one of four U.S. military servicemen honored during a third-quarter timeout, Deseret News reports. During his introduction, the arena’s P.A. announcer revealed that Mills claimed that he could dunk. Urged on by the crowd, the Air Force veteran decided to demonstrate his skills with a windmill slam.

Mills has the bravado to match his athletic ability, too. “You should see me without fatigues and boots,” the airman told USA Basketball media director Craig Miller after the dunk, according to Deseret News.

As impressive as Airman Mills’ dunk was, it was hardly the only high-flying action at Thursday’s USA Basketball Showcase. NBA stars such as Kyrie Irving, Kevin Durant, Kevin Love, Anthony Davis and many others all made their case for inclusion in the 2014 FIBA World Cup and, eventually, for the 2016 Summer Olympics. Ultimately, Irving’s 23 points led USA White to a 128-106 victory over USA Blue.
