Saira Khan soldiers on despite an injury, and the recruits' decision-making skills are tested when they're forced to make a call on who to shoot and who to save in a hostage rescue task. Jake Quickenden is brought in for examination as his suitability is called into question.

The remaining celebrities are put into pairs for 48 hours of trust exercises, beginning by rappelling down a 100-foot rock face, relying on their partner to break their fall. Once the task is complete, they must run three kilometres back to the van, but Ore Oduba struggles, leaving him and his partner Shanaze Reade stranded on the mountain overnight. In the final task, the recruits carry a 40kg fuel drum in pairs across four kilometres of gruelling terrain.

Twelve celebrity recruits remain from the original 14. Entering the next phase, the celebs face a series of tasks that will test their resilience to the max.

At the end of the episode, the DS drop two recruits from the training program.

Chief instructor Rudy Reyes puts Ashley Cain and Maisie Smith to the test, challenging them to get all their equipment across a body of water by zipline, without it getting wet. Finally, back in the blistering heat of the Jordanian desert, two teams of recruits must work out how to load and pull a 200kg sled loaded with equipment up a narrow ravine.

The celebrities face the penultimate survival phase of the course, where they prepare for life on the run behind enemy lines. An ambush triggers traumatic memories for AJ Pritchard.

Their mindset is also tested under pressure during a rescue mission when they are tasked with extracting two fellow recruits who have been taken hostage.

The celebrities are tested on their mental and physical resilience, including an ascent to the top of a 200-foot cave, where they're ordered to abseil back down again. The second task is murderball: a serious test of physical strength and aggression. Finally, the recruits are tested emotionally when they must write a death letter to their loved ones.

The trainees must prove they can trust their team, their leaders and themselves in a challenge so gruelling it leads to the medical withdrawal of three incapacitated recruits. For the second task of this phase, the celebrities are put through an individual challenge in which both their physicality and trustworthiness are put to the test.

One by one, the recruits must pull themselves across a 300-foot-wide ravine, before dropping 160 feet to the extraction point. An early-hours beasting is designed to weed out the weakest recruits. The recruits must also prove to the supervisors that they have what it takes mentally when they're offered a phone call to their loved ones back home.

The remaining recruits face a rough bout of pontoon wrestling. The hardships of jungle life take their toll, including draining weather, a lack of sleep and a calorie deficit from limited ration packs. This leaves the celebrities in far from their best condition as they embark on a simulated mission behind enemy lines.

For their final challenge, the five remaining celebrities endure intense interrogation, the most feared phase of the course. They must go through psychological and physical punishments designed to break their will and force a confession.
