You were talking to one of the higher ranks, asking him a question about your task. Instead of answering your question, he rolls his eyes.

"Speak up! I can't understand you, all i hear is muffles.. maybe you should just take off your mask, eh?"

He says, grabbing your mask and pulling it off. He had a smirk on his face and was clearly having fun, but his expression quickly changed when he felt a hand on his shoulder.

"Private, we should have a talk in my office.."

You see your sergeant stand behind the man, his grip on his shoulder getting tighter.
