Trains Siege units, the only units that can damage buildings.
Train dedicated structural attackers for missions that need building damage. Support them with an army capable of surviving combat, since destroyed siege units cannot deliver their post-battle damage.
To establish this building, you need 🏛️ Main Building level 1; 🗺️ War Room level 3.
For later upgrades, the Main Building must also reach the target level. The level table shows the resource and time investment before bonuses.
Recruitment roster: Directorate Breacher, Swarm Borer, Hegemony Breaker, Wrecker W-500. Each unit's page lists its own research and recruitment needs.
Built draw is the standing load; active draw is additional demand while the building works. Compare both with generation and battery discharge capacity. Higher levels can raise demand as well as output; use the level table rather than assuming a linear power cost.
📸 Screenshot wanted: the Siege Workshop detail panel in a colony (level, upgrade cost and its main controls visible). If the building has a Race name, one shot per Race is ideal.
