Who is in the SAS: Who Dares Wins 2020 cast?
As usual, the Channel 4 show has started with an enormous cast, which will no doubt quickly be whittled down as the series progresses.

Ant left the army and enlisted in the Royal Marines in 2005 before joining the Special Boat Service as a point man and sniper in 2008.
It's a common misconception that Ant has never been a member of the SAS.

Ant is joined by fellow forces veterans, Foxy, Billy and Ollie, who are all back for the new series.

Mark "Billy" Billingham spent a whopping 27 years in the SAS and even received an MBE when he led a mission in Iraq to rescue a British hostage. He was a Warrant Officer Class 1 - the highest rank in the SAS. Aside from that, he has also been a bodyguard for the likes of Tom Cruise, Angelina Jolie and Kate Moss.
Ollie Ollerton was also a part of the Special Forces and joined the Royal Marine Commandos when he was 18. After a gruelling selection process, Ollie joined the Special Boat Service as a Special Forces Combat Frogman, taking part in high profile missions across land and sea.
The fearsome foursome are also joined by new DS, Jay Morton, who spent 10 years in the SAS and only left his duty a year ago. Jay is the mole in the 2020 series and will surely have a lot of information to pass back to Ant and his team.
