Inanimate objects, have "Structural Damage Points" or SDPs. When an object loses all its SDPs, it is rendered useless; (a vehicle shuts down and grinds to a halt, a weapon will no longer fire, etc.). It is destroyed when it reaches twice its SDPs in damage. To keep things simple, (and to avoid too much rolling of dice), large scale weapons inflict points of damage called "Kills", which represent destruction on a much larger scale. Kills are used for such things as giant mecha robots and spaceships. Weapons that inflict Kill damage are not usually small enough to be carried around by characters.
