Sunday night's episode of Channel 4's Celebrity SAS: Who Dares Wins kicked off with an explosion of emotion as the remaining 12 celebrities - who include AJ and Curtis Pritchard, Fern McCann, Dwain Chambers and Ashley Cain among others - tackled a challenge which questioned their ability to stay calm and stay focused without losing their nerve. Described by the narrator as one of the most violent tasks on the course, the challenge required the application of extreme violence coupled with composure.
The Channel 4 series sees the celebrities - or recruits as they are known - tested to their physical and psychological limits, as they confront surprising truths about themselves, while tackling some of the most brutal courses and challenges that the series has ever offered. These courses are run by an elite team of ex-special forces operators from the UK and USA. Read here to see all of the celebrities who are taking part.
Explaining the task on the show (which aired on Sunday, September 25 at 9pm on Channel 4), SAS instructor Jason 'Foxy' Fox said: "You need to know when to turn it on and off. Open the lid and then put it back on".
