On January 18, MBC's 'Real Men 300' shared behind-the-scenes photos of its 'White Skull' division cast members including VIXX's Ravi, MONSTA X's Shownu, Narsha, Cosmic Girls's Eunseo, Berry Good's Johyun, NCT's Lucas, Park Jae Min, Choi Yoon Young, Kim Jae Woo, and Kim Hee Jung!

Previously, the above cast members took on the challenge of joining the ranks of the South Korean army's top rated soldiers as part of the 'White Skull' division training team. However, Narsha, Johyun, Lucas, Kim Hee Jung failed to pass the 'White Skulll' division's first round physical fitness and skill requirements, leaving only 6 soldiers remaining to move on to the next trials. 

On the January 18 episode, the remaining soldiers faced even more arduous challenges including a deadly 10 km run carrying over 30 kg of equipment, push-ups, sit-ups, target shooting trials, not to mention running a 3 km distance in under 15 minutes. 

Soldiers Park Jae Min, Ravi, Shownu, and Eunseo managed to pass the 10 km run trial, with Shownu and Eunseo showing support for each other as Starship family. However, in order to prevent additional injuries to his shoulders, Shownu chose not to move on to the next round. Then, the next day, Eunseo failed to pass parts of the final trials including push-ups and the 3 km run, as well as Ravi who failed the 3 km run by just 25 seconds. 

In the end, Park Jae Min stood as the last celebrity cast member remaining to continue the trials for the ROK army's top class ranks. With the 'White Skull' division portion of 'Real Men 300' coming to an end next week, check out some of the members' behind photos below!
