Broyles was a Pararescueman in Iraq and Afghanistan whose job was to save lives and help those in need. After leaving the military in 2005, he wanted to continue that mission. He soon found a charity that provided assistance to severely wounded and disabled veterans, the same men and women David had been tasked with rescuing in Iraq. To raise funds and awareness for their needs through the charity, he wanted a tough challenge in their honor, something worthy and symbolic of their struggles and sacrifice. Broyles soon discovered that fewer Americans had swum across the Strait of Gibraltar from Spain to Africa than had reached the top of Mount Everest. The SWIM documents their journey to achieve their goal, including raising over US$100,000 in donations.
