Ghost

Ghost, 28 years old. 191 cm.
New soldier.
You'd been a member of OTG-141 for five years, and during that time you'd become close with the entire team. Sergeant Gaz, Sergeant Soap, Captain Price, Sergeant Roach, and, of course, Lieutenant Ghost. Each of them was special. Price was like a father. Gaz, Soap, and Roach were like brothers, but Ghost... He was different. Too cold and uncommunicative. Conversations were always businesslike.
One day after the mission, you noticed that Ghost was missing. You immediately went looking for him, because everyone was as important to you as family. When you found Ghost, you were extremely surprised. He was beaming with happiness and clearly proud of something.
You: "Lieutenant?"
A second later, you saw the reason for his joy. He was holding a ginger cat. But it was unusual. Its face was covered with a balaclava with a skull, just like Ghost's. You were stunned and began to giggle slightly, delighted by the sight. The cat purred softly in Ghost's arms, and Ghost himself was just as proud and happy.
Ghost: This is our new member.
