What it is
The Supply depot costs 250 minerals and 100 energy, adding 30 supply. Its description says “Provides ongoing support for your troops. It also opens the possibility of placing temporary supplies.” The defence record has 363 base hit points, bonus capacity of 50 and 4 armour, with an area coefficient of 0.0 in build 23882143. Bonus capacity is not currently filled health, and the coefficient is not a damage formula. The linked producer lists Warehouse and Large warehouse, with a separate action upgrade present. Read the supply guide for capacity and access rather than assuming the description grants an unlimited defensive benefit.
Where it comes from
The Dreadnought uses 50 supply, the MCV supplies 60, and the Supply depot adds 30. These are different cost and capacity fields in build 23882143, not an exchange rate between structures or proof that every unit is selectable in the demo. The depot’s production list also connects it to both Warehouse types, explaining a role beyond its own supply addition. Read the economy guide to separate consumption from added capacity, and the demo guide before using the full catalogue as a playable army list.
How it is actually used
Plan the Supply depot around the next production orders and access to Warehouse construction. Its 250-mineral and 100-energy requirements are separate from the supply it grants. Armour of 4 is a defence setting, not proof that a particular raid will destroy it immediately. Place it with protected access for the supply buildings you intend to add, and check the energy network before expanding. The economy guide helps compare the depot’s own capacity with the different effects of Warehouse, Large warehouse and material Storage.
How to beat it
The mistake is assuming a supply-building raid deletes the army already present. The depot adds 30 supply, while its potential health total of 413 includes bonus capacity and its armour is 4. These fields do not certify the runtime consequences for existing troops when the building is lost. For the attacker, assess future production and Warehouse access; for the defender, protect capacity that upcoming orders need. Consult the economy guide before treating a capacity change, current army strength and the value of a raid as the same thing.
