Gold Depot
The Gold Depot is one of the resource storage structures in the game. It stores a lot more of their respective resource than their resource generating counterparts. These structures also serve as a sort-of a prerequisite to upgrading the Command Center since the resource amount they require is only hampered by your current maximum resource cap.
It is one of the primary targets of the Sniper units so it is a good idea to not leave these structures at the edge of a base without any defense. These structures also has low to moderate hit points and can take relatively little damage.
In PvP, it is one of the structures that "gives" resources when damaged. Obtaining over 50% of your opponent's resource yields one star for completion.
