Find the militaries' documents

The  task is a storyline mission featured in S.T.A.L.K.E.R.: Lost Alpha.

"At the HQ. It's on the third floor of the Institute. That's where they keep those damn papers. But it's a mission getting there. By day, the area is teaming with patrols but not as much at night. I'll tell you this for free: if you wanna get inside, you'll have to go through the catacombs - you stand no chance at the gate, but it's up to you."
