Take caution as losing a ship here without the Damage Control Item can lead to a permanent loss of the ship.
PvP: Here, Admirals battle their fleets against each other for Experience, Losing a ship in a battle here is only a simulation, and is recovered after the battle, it's a good way in leveling up your ships.

Historical Battles: As the name implies, these battles are based off on their real life counterparts and is only a single Battle long, this rewards you with a fair amount of resource and a remodeling kit used for upgrading ships, but you may only enter for a minimum of 8 per day (except for events)
