S3, E3: The ultimate celebrity social experiment, Special Forces: World’s Toughest Test, returns for a third season, enlisting a troop of household names to endure some of the harshest, most grueling challenges from the playbook of the actual Special Forces selection process. This time around, the recruits will be training in Wales, the home of British Special Forces Selection, and will endure the harsh reality of ocean warfare. The recruits are pushed to the test once again and face new challenges including escaping a boat crash, an intense combat exercise, battling against each other in an intense boat race, and hauling 500 pounds worth of supply kits up a steep mountain.
