The 14 remaining recruits are now halfway through but are about to face their toughest expert yet. Ken is serving Lieutenant in the Republic of Korea's Underwater Demolition Team, AKA ROK UDT, and his unconventional methods push even the toughest recruits out of their comfort zone.

ROK UDT are based on the US Navy Seals and follow a similar training regime, but nothing will prepare the recruits for the unorthodox thinking man position and other water-based exercises that force some strong competitors to throw in the towel.

But that is not all Ken has up his sleeve - dragging truck tyres up hills and carrying boats on their heads is just the beginning of the misery they are about to face. And with the men dropping like flies, it is now a head to head between the remaining men and women in the ultimate battle of the sexes.
