FOXs ultimate celebrity social experiment, Special Forces: Worlds 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. On their way to base, and with hardly any time to get acquainted, the new recruits are faced with their first challenges which include taking a mighty leap out of a moving boat onto a helicopter, testing their endurance by treading water as a group and bungee-jumping off a 12-story viaduct.

The recruits face new challenges including escaping a boat crash and an intense combat exercise.

Recruits must unlock a safe in a gas-filled room, perform a helicopter insertion into the blistering cold sea, and select recruits are forced to bury their teammates into coffins after cheating in a previous challenge.

Entering their final week of Selection, the remaining recruits are challenged mentally to harness their vulnerability and shift their mindsets to overcome the final tasks. The recruits fight the "Redman," escape an ambush and evade an enemy hunter base, and approach the most terrifying phase of the course, resistance to interrogation. As the recruits experience the most challenging part of their journey, they must try their best to conceal that they have been working with the Special Forces in order to successfully pass Selection.

As the recruits make their way to base, they are faced with initiation and their first brutal challenge: repelling out of a military-grade helicopter. Later, the recruits get a taste of what its like operating behind enemy lines as they carry supplies weighing 800 pounds in sweltering 100-degree heat.

With nothing more than a radio kit and each other, the recruits must communicate effectively and move quickly as they work together to identify fallen comrades in a casualty evacuation test behind enemy lines. Then, when their teams mission is compromised, they must cross rooftops to make it to extraction.
