Screen-n: The USP factor for one screen (nuclear damper, meson screen, or black globe) selected by the firing player is reduced by the indicated amount. Damage must be divided as evenly as possible: no screen may receive two hits until all other screens have at least one, or three hits until all others have at least two.
Weapon-n: Each hit destroys one battery of weapons, either offensive (laser, energy weapon, meson gun, particle accelerator, or missile) or defensive (sandcasters, or repulsors). If the ship has only one battery of a type (including spinal mounts), a hit reduces its USP factor by the indicated amount. As with screens, the firing player chooses which weapons are affected, but damage must be divided as evenly as possible.
