It had a different code to the rest of the doors too so was off limits. A series of screens hang on the end wall. All switched off. But all angled to point down at one central point on the floor below. A podium which faced towards them and contained a glass surface that looked like some sort of control station.
The weapons racks which stood just off centre of the room held dozens of rifles, multiple rocket launchers, crates of grenades and suits of heavy body armour. A large desk with what looks like a screen sunk into the centre stands at one end of the racks, right in the middle of the cavern. Again, there were more weapons here than what thirty soldiers would ever need. A series of tables with stools fill the gap between the beds and the racks. An eating area.
