This location is a standard radio relay tower with machinegun turrets guarding its entrances. Inside is a blue system relay terminal which US government supply requisition holotapes can be loaded into to call for supply drops. There is a bank of lockers along its southwestern wall and a locked footlocker (Picklock 0) and ammo box in the corner of the room. There is also a first aid box next to its southeast entrance.
