Large Resource Storage Facility and Supply Depot

From the author

The Large Resource Storage Facility provides 20,000 units of combined metal and energy storage alongside 500 supply capacity — the largest storage structure in the game. At Tier 3 it enables the resource reserves needed to sustain prolonged Tier 3 and Tier 4 operations without income fluctuation disrupting critical build queues. The supply grant also contributes meaningfully to fielding larger armies.
