Naval units are essential for maps with significant water bodies, providing powerful offensive and defensive capabilities. Landing Ships (12000G) are crucial for transporting ground units across water, enabling amphibious assaults and opening new fronts. Cruisers (18000G) are versatile naval units, strong against air units and submarines, making them excellent for naval defense and escorting other ships.

Submarines (20000G) can dive underwater, making them invisible to most enemy units until they attack or are revealed by a Cruiser. They are highly effective against other naval units and can surprise unsuspecting enemies. Battleships (28000G) are the kings of the sea, boasting immense indirect fire range and power, capable of bombarding ground units and buildings from a safe distance. Naval units are expensive and require Ports for production, but their strategic impact on water-heavy maps is undeniable.
