Battleships are a type of Warship in Empire Earth and the most versatile. Their high attack, hitpoints, and long range, plus their large Area of Effect means they are the kings of the sea. However, they are the slowest warships available, and their high cost along with slow production speed make them difficult to manage. Galleys, Submarines, and iron Siege Cannons are Battleship counters.
The main Battleship counters are Galleys, Submarines, Elephant Archers, Archaic Impact Weapons (like the Catapult), Impact Cannons like Basilisks and Bomber Planes. A small group of Cyber Ninjas are potentially dangerous against a Battleship, as they can quickly deal a high amount of damage to it, therefore your ships shouldn't be placed too close to the land.
