Kody Brown Makes a Dramatic Fall and Brittany Cartwright Breaks Down in Tears in Special Forces’ First Season 4 Teaser

The first look at season 4 of Special Forces: World’s Toughest Test is here!

Ahead of the Sept. 25 premiere of the popular competition series, which is set in Morocco this year, fans are getting a glimpse into the “extreme circumstances of urban warfare” that the group of 18 celebrities will face in the ultimate test of mental and physical strength.

According to the official synopsis, this season’s challenges include “a supply search in an abandoned village where they must race to extraction, a treacherous rat-run through dark and narrow tunnels, a plane shell dunk drill where pairs of recruits will be submerged underwater and must escape, a death-defying urban ladder crossing between buildings 50 ft above the urban streets, and much more.”

“The weak do not belong,” the narrator states at the start of the trailer.

Jovon “Q” Quarles, who is part of an elite team of ex-special forces operatives, then explains that the participants are going to “get a crash course of what it’s like to be in our reality.”

In a new twist, some recruits will be arriving with loved ones but must compete individually.

This is true for singer Jessie James Decker, who fearfully watches her athlete husband Eric Decker fall backward over a body of water.

He is joined by reality star Gia Giudice and Olympic gymnast Shawn Johnson East — who also arrived in duos with Gia’s mom, The Real Housewives of New Jersey’s Teresa Giudice, and Shawn’s husband, former NFL player Andrew East — as well as Sister Wives’ Kody Brown.

They let out a loud scream as the narrator warns, “You will potentially die.”

Clips of The Valley star Brittany Cartwright fighting tears, football player Johnny Manziel trying to keep his head above water and influencer Brianna LaPaglia struggling to breathe lead up to the declaration of their ultimate goal: “Concentrate on staying alive.”

The cast is comprised of celebrities from “all genres and walks of life.”

Other athletes in the competition include NFL alum Randall Cobb, Olympic soccer player Christie Pearce Rampone and retired NBA player Nick Young. The cast is rounded out with actor Jussie Smollett, Montana Boyz TikToker Mark Estes, model Chanel Iman, Real Housewives of Atlanta alum Eva Marcille and actor Ravi V. Patel.

“In this experiment, there are no votes and no eliminations – just survival,” per the official logline. “These celebrities, who are so used to being in the spotlight, will quickly learn the meaning of ‘no guts, no glory’ – and no glam.”

“The only way for these recruits to leave is to give up on their own accord, through failure or potential injury, or by force from the DS.”
