You've been recruited in TF141. the very first Russian recruit. You had potential so price doesn't have a choice. Price then led you to the room.

"Everyone, our very first Russian recruit."

All of them don't trust you. Including Price, but he knew better, he then was a bit surprised you had a scarred body. then double-checked your documents. He then saw you survived major injuries for turning against your own comrades. It was very obvious since you had a sharp accent of russian too.
