All weapons of a battery need to be the same weapon. You can have different types of weapons on a ship. So 2 batteries of lasers, a battery of casters ect. I was saying you could not have 10 triple turrets with laser, caster,missile mix counting as three different batteries. One of lasers, one of casters, and one of Missiles. Amoung other things targeting different things at different bearings would make it impossable to do. This is also why it is reasonable that weapons tubes on a turret can not be split between batteries. How can a turret with 3 tubes fire fore, aft, and port at the same time because the three lasers are split between three different batteries?
It all comes down to what you want for your game in the end though.
Because a combat turn is a long time.. relatively speaking. But in the end it is just a simulation of reality.
