Conquering a rival Sponsor's capital city is often the most challenging 'boss' encounter in a Domination victory. Capital cities are heavily defended with high combat strength, multiple defensive buildings (e.g., Perimeter Defense, Citadel), and often a garrison of powerful military units. A successful assault requires careful planning and a combined arms approach. First, use Artillery and Bombers to soften up the city's defenses and garrison units from a distance. Then, move in with heavily armored Melee Units (Marines, Tanks) to absorb damage and capture the city. Utilize Air Units (Fighters, Bombers) to counter enemy air defenses and provide additional damage. Ensure your units are fully upgraded with their Affinity bonuses. Consider using Orbital Lasers to further weaken the city. A sustained siege, rather than a direct assault, is often the most effective strategy, slowly grinding down their defenses before the final push.
