Anyone know where the key to communications is?

I used a grenade to get into security and im worried I might have lost it in the blast

According to a map of the soldier quarters I found on a website online, it can have like two locations
Barracks B, the lit room if you got the generator on, its on one of the bunks.
Or Barracks A, the dark room. Careful when going in there, there are rats feasting on a body and its most likely a spot where the beast comes out outside of the light areas.
It has random locations in these areas.
Hope this helps.

basic spoiler
a room has a note that says where the key is hidden

unneeded spoiler
its in one of the bunks ,note gives name of what bunk (its kinda hard to find on the bunk but its there)

There's also a picture showing you the top down view of the barracks. If you combine that knowledge with the note you find, you'll find the key on the bunk.
