Having gotten introduced (as much as any introducing actually went on) and stocked up on supplies, everyone heads up to the first floor. It's a single large room, resembling a huge hangar or parking lot. The roof is a large, arching dome, and there is a monumental set of double doors that you could probably fly a plane through. A swipe of the security card is sufficient to activate the now-powered doors. The hydraulics kick in, and the doors slowly start to slide open with a great deal of noise.
As the doors pull apart, a blast of cold air rushes in and you can see large quantities of snow being shaken off the exterior, as well as a rather bundled up soldier with a cigarette hanging out of his mouth and a shocked expression on his face. He's wearing a thickly padded uniform that obviously has several layers under it, a scarf that he has apparently pushed aside while he was smoking, and a black fuzzy hat with a hammer and sickle on it. The doors finish opening, and while he's staring at you you can see that some sort of convoy had come to a stop behind him, and had unloaded several containers of fuel for their vehicles.
He drops his cigarette and runs off toward the convoy, yelling something in Russian. Soldiers that were tending to the vehicles stop what they're doing and start scrambling for their guns, but it seems you've caught them off guard. Immediately outside the doors and to the right there are some large broken-up boulders, towards the left there is a small drop-off, that looks just low enough that you could duck inside and stand up to look over the top, and the doors themselves are obviously thick enough to stop whatever they might shoot at you. The convoy itself is about 85 meters away from the door. It would probably be a good idea to make your move before they get their act together.
