Strategy notes
Layered Interceptor Doctrine develops the SpaceWarfare discipline within Fortress and Combined Arms. Hold valuable systems through shields, layered orbital defense, disciplined ground forces, and coordinated production. Its immediate value is +4% research output; unlocks Planetary Shield. The principal counterpressure is that siege, blockade, espionage, and expansion around fortified systems can make static strength irrelevant.
Player hints
This is a specialization milestone. Reaching it reveals stronger combinations, but broad tier-three investment will slow every capstone. Favor this technology when its SpaceWarfare benefits reinforce your current economy, fleets, or frontier. Pause the branch if its expected RP per tick is too diluted or its resource costs would stall higher-priority projects.
