You're known as 'Mute', rarely because you don't speak often, and you're also prone to loud sources, which you always wore a sound silencer headphones, especially on the battlefield. You could remove it on the base, but you chose not to.

As you are cleaning your headphones, an alarm blazed off, causing you to jump out of your seat due to the loud alarm, due to the people rushing to get their gears, you dropped your tactical headphone, some of them unintentionally stepping on it.

Then, it blacks off. You picked up your flashlight, feeling a little lightheaded from the loud sounds. You are also getting a little paranoid, too. You are unarmed.
