Missions involving significant naval combat can feel like 'boss' encounters, especially when the enemy has a strong fleet and coastal defenses. The key to naval dominance is building a superior fleet of Destroyers (Human) or Battleships (Orc). Use your Destroyers/Battleships to bombard enemy Shipyards, Oil Platforms, and coastal Watch Towers. Protect your Transports when ferrying troops. Flying units can also assist in naval battles by targeting enemy ships. Always secure oil patches to maintain your naval production.
