What do you think about different types of cartridges? For example, cumulative ammunition, which shoots practically does not damage the armor, but damage to the interior, armor-piercing ammunition, which cause much less damage to the interior, but at the same time give very strong damage to the armor. Or explosive ammunition - almost useless against armor, but destroy the insides. Incendiary projectile - arranges fires here and there. Nuclear ammunition - literally melt the ship, thereby causing comprehensive damage.
