Pick of the Day
Special Forces: Ultimate Hell Week, 9.30pm, RTÉ 2
Last week's opening episode saw 24 civilian recruits begin a grueling Special Forces selection course designed by former members of Ireland’s elite Special Forces unit, the Army Ranger Wing (ARW).
They're a mere 24 hours into the Hell Week course and six of the twenty-four recruits have already been eliminated. The remaining 18 will be under no illusions about what lies ahead for them.
Day 3 sees recruits pushed to their absolute limits in a series of back-to-back events, testing their fear of heights, freezing temperatures and open water. Not everyone will make it to the end of the day.
