This paper model is a Supply Depot, from the military sci-fi real-time strategy game StarCraft, the papercraft is created by KGH. The supply depot houses all the goods, tools and accessories that are necessary for the running of a terran base. It is used by both military units and colonists.
Under the Terran Confederacy, supply depots were standard for military bases and possessed a universal design. This design was that of a low, one-story, metal-clad structure, a spacious waiting area and a counter separating said area from the storage racks on the other side. Such storage includes weapons, ammunition and even SCVs.
During the Second Great War, through research of protoss artifacts, Doctor Egon Stetmann gained insight into protoss architecture and was able to develop orbital depots—supply depots capable of being dropped from the Hyperion and surviving entry through a world's atmosphere to a point designated by a SCV-planted beacon.
