[락앤롤2026] UDT 기본과정 극기주 통합본(무수면 112시간 훈련 기록)

Summary

This video follows UDT Basic Course trainees through Endurance Week, a roughly 112-hour, sleep-deprived training period designed to test how they function under battlefield-like fatigue, cold, stress, and physical strain. The subtitles provide no video timecodes, so key moments are identified by training phase rather than exact clock time.

Before the Week Begins

Instructors explain that the exercises are meant to test trainees’ reactions to unpredictable situations and their ability to follow commands while exhausted. One trainee admits being too nervous to sleep even before training starts. The instructors warn the class that the week will push them to their physical and mental limits, then declare the start of the 72nd class’s Endurance Week.

Early Training: Cold-Water Drills

Trainees enter water reported to be about 15°C. Instructors emphasize the danger of losing body heat and the importance of controlling breathing and helping one another. Shivering and struggling to keep warm, trainees work to raise their body temperatures after getting out.

Several describe the cold and exhaustion as severe, but say thoughts of family and the determination to get through another challenge kept them going.

First Team Competitions

The class moves into group exercises, including a maritime event involving coordinated pedaling and steering. Instructors correct the trainees’ technique, urging them to work in rhythm and use the full pedal stroke. The emphasis is less on individual strength than on moving together and keeping the team on course.

Wooden-Structure and Soccer Exercises

On the second day, trainees carry and maneuver a wooden structure as a team. The load shifts when members fall out of position, forcing those at the front to bear more weight.

A soccer match also features in the day’s activities; the losing side faces additional physical punishment. The exercises reinforce the instructors’ message that teammates must listen, keep pace, and support anyone who is struggling.

Tire Rolling and Extended Teamwork

Trainees compete in a tire-rolling event, with the winning group earning a more comfortable meal position. Later, teams move heavy equipment and inflatable boats (IBS), with instructors repeatedly demanding better coordination and louder responses.

As fatigue builds, some trainees lag behind, and team leaders are pressed to keep the group moving together. One trainee mentions a sore knee, while others say encouragement from classmates helped them continue.

Later Stages: Sleep Deprivation and Withdrawal

As the sleepless training continues, trainees describe becoming increasingly drowsy and losing track of what happened from one day to the next. One trainee is particularly affected when a close friend withdraws, recalling the friend’s request that he finish the course for both of them.

The group’s shared hardship becomes a source of support: trainees say that even seeing one another can give them strength.

Final Day

Instructors set up another competition to push the class through the final stretch. They explain that severe sleep deprivation can blur awareness and make even a small mistake dangerous.

The trainees continue through boat-carrying drills and other physically demanding tasks despite pain, wet clothing, and wounds caused by repeatedly moving between seawater, mud, sand, and gravel.

The Finish

After describing the training as an exhausting journey of more than 100 km of running and walking, the trainees reach the end. Seeing the Korean flag brings one trainee to tears. Those who finish express relief and pride at making it through without serious injury.

Instructors congratulate the class, tell them to remember the moment, and welcome the 72nd class back from “hell,” while reminding them that harder special-operations training still lies ahead.
