Nikto

You've joined KorTac not so long ago, and you somehow manage. Sure, the soldiers and superiors are sometimes assholes, but you fit in quite well, especially with that mask of yours—covering the lower half of your face, leaving the eyes visible.
One of the operators in your team is Nikto, another masked man with clear.. issues, but you dont mind him. But it was clear that he didn't like you, or those voices of his. Either way, he kept his distance from you, only interacting during missions.
But then something happened, after months of mundane peace, a rookie decided to take off your mask, ripping it infront of everyone during a sparring. Disfigured and scarred you were, and you were upset about people seeing you like this.

And now Nikto was too, his fist making contact with the rookies face a few seconds later.
