Season 4 of Special Forces: World's Toughest Test has thrown a few curveballs at the audience. Every year, the Fox reality TV show sees multiple celebrities undergo strenuous physical and mental challenges inspired by real-world Special Forces training. From reality TV stars to athletes, this season featured multiple pairs - a first for the series - that included spouses and a mother-daughter duo. The directing staff of the show, Rudy Reyes, Jason Fox, Mark Billingham and Jovon Charles, implement a series of grueling tasks for the recruits to tackle.
