SAS: Who Dares Wins returned to Channel 4 screens on Monday night with a fresh batch of recruits in a new location.
The 20 new contestants are already being put to the brutal test of the punishing jungle phase of SAS selection in Vietnam.
The new series titled SAS: Who Dares Wins – Jungle Hell landed on Channel 4 on Monday evening and saw The Special Forces training welcome a new DS member as the cast only faced one exit in the first three days.
Channel 4 viewers can now tune in for weekly instalments for the next six weeks as the recruits face gruelling new tests of endurance, resilience and strength.
A first look clip at the coming scenes saw the contestants already being thrown into a terrifying medical emergency, as one recruit collapses with a seizure.
In the new video, an upcoming episode shows the recruits panic while in their dorms, as Aliyah starts having a seizure while lying in her bed.
The 26-year-old Londoner looks terrified as her eyes shoot open wide and her new co-stars rush to help her amid the frightening convulsions.
A voice is heard commanding the filming team to "get an ambulance now", before the scene ends as the full ordeal is set to play out later this series.
Speaking ahead of the show airing, Aliyah hinted she would be going through some hardship, and said: "I don’t think I have a fear anymore to be honest, my experience was very unique physically and spiritually."
The influencer, who was born in South Africa, added she wasn't prepared for the heat of Vietnam and that became one of her biggest struggles on the show.
Fan favourite Special Forces staff who are on-hand to help the recruits navigate the new challenges have returned to the fold, including Jason ‘Foxy’ Fox alongside Rudy Reyes, Chris Oliver and Chief Instructor Billy Billingham.
Speaking to the Mirror last year Foxy, 44, explained that getting through these physical trials is a major mental challenge too both in the show for the newbies, and in the field.
"Mental strength plays a huge role - I'd say it's 70/30. You can be physically robust but it's all in the brain,” he said.
"Some of the stuff you do in the Special Forces is f***king bonkers. When you sit down and actually think about it, it's got everything to do with your mind."
Matthew Ollerton, who appeared on the show, alongside him, agreed: "Your mind gives up way before your body. It's all in your head. Your brain always looks out to protect you."
SAS: Who Dares Wins continues next Monday at 9pm on Channel 4.
