The recruits are pushed to the test once again and face new challenges including escaping a boat crash, an intense combat exercise, battling against each other in an intense boat race, and hauling 500 pounds worth of supply kits up a steep mountain.

Recruits must unlock a safe in a gas-filled room, perform a helicopter insertion into the blistering cold sea, and select recruits are forced to bury their teammates into coffins after cheating in a previous challenge.
