Special Forces: World's Toughest Test Episode Rating Graph

As a test of their character, they are tasked with a 2-mile race, navigating treacherous terrain, while carrying a 220-pound boat.

The final group of remaining recruits attempt to go behind enemy lines without being captured, and face tough lessons of survival, leadership and how to decipher a map.

The recruits are captured and taken into their final stage of selection: 12 hours of military-grade interrogation; resistance and the will to survive are key, and only the strongest recruits pass the course.

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.

The recruits undergo a search-and-rescue course, crawl along a rope suspended over a canyon, face a grueling three-stage endurance test in the mountainous terrain, and a brakeman rope challenge.

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.
