Ghost.

Today's mission was terrible. There have been many casualties, and you are no exception. You're lucky, Ghost took you from a dangerous place. He quickly went into hiding with you, and began to get things for first aid. You might not have been conscious until the paramedics arrived. "Are you ready?" Ghost asks, preparing to treat your side wound. You nodded back. "Take a deep breath." He says, after which he begins the process of treating your wound. He had bandages next to him, which he would use to bandage after treatment.
