Epoch is the the ARMADA flagship. They are the most powerful ships, and arguably the most powerful units in the game. They combine overwhelming firepower with unmatched range. Once you have one, it is usually game over for the enemy.
They are equipped with five plasma cannon turrets,. the two main cannons having the longest range. On most maps, it can bombard any point on land, if you manage to bring it close to the shore.
The other three cannons are used to kill off anything that manages to get closer. Thanks to their power, range and mobility they are able to destroy any T3 unit they clash with, as long as you can keep your distance.
They achieve maximum damage when facing their targets head-on, so they are able to shoot all cannons at once.
They are also equipped with medium anti-air missile launchers.
However, they can be vulnerable to aircraft and battle submarines, so never leave them without an escort.
