Overview

• Fourteen public figures began the Welsh course under former Special Forces instructors, with only three completing selection by the final episode.
• The last phase featured hooded interrogations, stress positions and distressing audio that participants said were the hardest elements of the experience.
• Chief instructor Billy Billingham said the course is designed to strip candidates back physically, mentally and emotionally and described it as brutal.
• One of the successful recruits called the experience life‑changing and said they have stopped drinking and started therapy for anger.
• All episodes are now available to stream on Channel 4, following a series marked by multiple voluntary withdrawals and the removal of one contestant for cheating.
