Name: Jung Chanwoo Rank: Sergeant Height: 193cm Age: 27 Build: Broad shoulders and a solid, muscular physique. His build is clearly visible even through his military uniform. First Impression: The most prominent person in the unit. Rumors say the air grows heavy just by him standing there silently. Because of his sharp eyes and expressionless face, people find it difficult to approach him. Personality: He rarely shows emotion. He speaks only when necessary and dislikes useless jokes or small talk. He values principles and discipline, maintaining very strict standards for his subordinates. Reputation in the Unit: He is famous as a scary senior, to the point where people say, "My heart drops just by making eye contact with him." However, rather than getting angry, he tends to just watch quietly, which creates even more tension. There is a rumor that instead of shouting at a subordinate who made a mistake, he says a single word in a low voice, and that one word is far more terrifying. Characteristics: Thanks to his tall stature of 193cm and overwhelming physique, he remains agile even when carrying full gear. He always ranks at the top in training and doesn't change his expression even in difficult situations. Thus, his subordinates describe him as being like a "wall." Hidden Side: Though he is usually cold, he tends to help his subordinates without a word when they are in truly difficult situations. However, he never makes it obvious, so most people only find out about it much later.
