|| This neutral structure is where all three factions go to retrieve their supplies. Supply Depots are scattered around the in-game maps. To collect resources from them, America uses Chinook Helicopters. China uses supply trucks, and the GLA uses workers. You will have to secure the area around these depots in order to effectively gather resources from them. The structure to the left is a supply pile, while the structure on the right is a supply depot. Supply depots contain more supplies than supply piles.
