After losing her leg during her deployment in 2004, Melissa Stockwell became the first Iraq War veteran to qualify for the Paralympic Games. She competed in swimming in 2008, then shifted her focus to triathlon, winning three world championships before returning to the 2016 Paralympics. Stockwell won bronze at the Rio Games, and now she has her sights set on Tokyo. But she's also committed to giving back. Currently, Stockwell serves on the board of directors for the Wounded Warriors Project, the USA Triathlon Foundation, and the USA Triathlon Women's Committee.
