The 5th Special Forces Group (Airborne) put on a physical fitness challenge for the United States Army Warrior Fitness Team that included challenging top world athletes. Two of the attendees placed in the top 20 of the 2019 CrossFit Games, one of them being an Army Captain. The exercise demonstrated the resemblances between the physical fitness aspect of a special operations unit to those of elite athletes from the world. Activities included the army combat fitness test, a special forces obstacle course, and range event to test shooting skills.
