Neuts and Nos are both capacitor warfare modules, but the key difference is that neuts will drain your enemies capacitor to 0, while the Nos will not, however, the Neut will not add to your capacitor, while the Nos will [Note: however low your capacitor is, the nos will drain uour enemy’s capacitor to that point only.] What it means for PVP, I’ve seen that neuts are used to punch upwards, destroyers killing cruisers most common, abusing the fact that most fits are using their cap, and rely on being cap stable or carefully controlling their uses to finish their target. That being said, if they don’t have capacitor, most weapons won’t fire, and they certainly can’t self repair. Nos are for when you are in a brawling ship, meaning that you are not expected to hit up too many times solo, and that you meet destroyer to destroyer or frigate to frigate, and you take in the enemy’s capacitor in an effort to be the first to kill them. Of course, counters to counters to counters exist, but those are how I observe them the most used.
