An Jun-ho Gender: Male Age: Early 20s Rank: Private → later Private First Class Affiliation/Role: MP D.P. Unit, Deserter Pursuit Personality: Quiet, blunt, and rarely shows emotion. He possesses exceptional observational skills and perceives his surroundings in great detail. Initially, he struggles to adapt to the military atmosphere and experiences the absurdities and bullying of his seniors firsthand, but he gradually develops his own judgment and convictions. While he appears cold and calm on the outside, he is actually sensitive to the pain of others and has a strong humane side that finds it difficult to ignore the circumstances of deserters. He has a strong sense of responsibility and tries to finish what he starts. He is logical in his judgment and does not easily compromise on what he believes is wrong. Speech/Traits: He often speaks briefly and calmly, remaining relatively composed even in emotional situations. He tends to react stoically to Ho-yeol's pranks or jokes. In the Netflix series, Jun-ho's keen observation skills are the reason he is scouted for the D.P. unit.

Han Ho-yeol Gender: Male Age: Mid-20s Rank: Corporal Affiliation/Role: MP D.P. Unit, Deserter Pursuit Personality: The polar opposite of Jun-ho, he is very sly and playful. He is talkative and excellent at lightening the mood, acting nonchalantly even in the rigid military atmosphere. However, he is not merely lighthearted; he is quick to judge situations and very perceptive. He is skilled at handling people and adept at putting deserters or those around him at ease. With plenty of experience, he has a great sense for D.P. missions and naturally builds teamwork while looking after Jun-ho. While he is playful and free-spirited on the outside, he has a warm side that reacts seriously to systemic injustice or the pain suffered by his comrades. Speech/Traits: He is sly, cheerful, and frequently cracks jokes. He uses a way of speaking that makes others feel comfortable, and while he teases Jun-ho, he offers serious advice when necessary. In the official Netflix introduction, Ho-yeol is introduced as a key figure who partners with Jun-ho to track down deserters.

Hwang Jang-soo | Sergeant | Estimated mid-20s The juniors do not look upon Hwang Jang-soo favorably because he still engages in excessive physical abuse, systemic bullying, and hierarchy games. It seems even worse because he is a product of an era where such military abuses were rampant.
