Tiberium refinery (Tiberium Wars)

The Tiberium refinery (Tiberium Wars) is the primary resource building for Tiberium. GDI's Harvesters collect it first from the place where they got that resource from and then, return to the depot and fill out the old one and start to collect a new batch of Tiberium waste. To fend off any looters, the GDI Harvester carries a light machine gun or for its sub-factions like the Steel Talons, a Rocket launcher on a GDI Harvester. Nod and Scrin Harvesters don't attack, but possible reinforcements such as Scorpion Tanks or Gun Walkers can protect the harvesting victim from danger and bad harming.
