Functions of the structure: Fuel production
Refinery is the source of fuel which is used for maintenance of army units and construction of some buildings. Workers are employable units in that structure and a refinery produces 20 fuel per hour. You need to research it for once then you can build as much as possible. It is a strategic structure because no fuel, no army. So, that makes it very important.
