Shield Arrays are a general purpose defensive field around a ship. These are the most common variant of shield due to their regenerative nature, yet have significantly less strength' than a shield emitter due to them working on a more 'absorption' focus of inbound fire, completely absorbing the kinetic energy, thermal energy, etc. Being absorptive allows them to accept additional power to the field generated while active, which is why they can regenerate. Their absorption quality also serves as very minor mitigation to damage, which is why they can survive significant amounts of firepower. Mounting multiple arrays gives options to field's emission. One option of the shield arrays is to have them all work in unison for a far stronger field, allowing harder hits to be taken along with more. Another is to have them all create layers of shielding, which works extremely well against shield penetration chance and weapons with the ability to penetrate shielding.
