GURPS - Basic Set 3r..

ATTACKING INANIMATE OBJECTSThere are many situations in which you will want to attack something rather thansomeone. Go right ahead. It can't hit back. Any inanimate object will have a DR (damageresistance) representing its innate "toughness," and a HT (hit point) score, representingthe amount of damage it can take before it is cut, broken, or smashed. Almost any attackon an inanimate object can be generalized as (a) cutting through a rope or bar; (b)breaking through a flat surface: (c) smashing a solid object to rubble. Use the listingnearest to the object you're attacking: modify as appropriate. To attack an object:(1) Figure hit modifiers for size, speed, distance, etc. - see p. 201. If you are using ahand weapon, and have a second to "aim" your blow at a motionless object, take a +4 tohit.(2) Roll to hit. as with a normal attack. Inanimate objects get no defense roll, unlessthey are actually combatants (e.g.. robots, military vehicles).(3) Roll damage normally for your weapon, if you hit.(4) Subtract the object's damage resistance.(5) Apply the remaining damage to the object. Edged and impaling weapons do notget a "damage bonus" - that only applies to living targets. When the object's "hit points"are reduced to zero, the object has been cut. broken, or otherwise destroyed.HT of a bar or rope is the damage required to cut it. HT of a wall or slab is the damagerequired to force a 2-foot-diameter hole. Impaling damage of the listed amount will makea small hole in a slab.A complex object will have two HT listings. The first breaks it and makes it nonfunctional:the second destroys it. For example, a weapons locker might have a DR of 4(thin steel), and HT of 20/50. If you use it to block the door, it will take 50 hits to reduceit to rubble. But 20 hits will ruin it as a locker!"Weapon to use" is intended as a guideline for the players and GM. rather than ahard and fast rule. In general, just make sure that the weapon being used is one thatcould reasonably affect its target! Use common sense. A hard-driven spear could easilypenetrate a door, but that would not break the door down. A club is unlikely to damage abasketball unless the basketball has nowhere to bounce. A sword may eventually cutdown a door, but the sword will be dulled before the job is over. And so on.Object DR Hit Points Weapon to use Object DR Hit Points Weapon to useLight rope ( 3 / 8 " diameter) 1 2 Any Wallboard ( 1 / 2 " thick) 1 5 Not impalingHeavy rope ( 3 / 4 " diameter) 3 6 Edged Plywood ( 1 / 2 " thick) 3 15 Not impalingHawser (1.5" diameter) 4 10 Edged Wooden slab (1" thick) 2 10 AnySteel cable ( 1 / 4 " diameter) 2 8 Not impaling Wooden slab (2" thick) 4 20 Not impalingSteel cable ( 1 / 2 " diameter)Steel cable (1" diameter)461630EdgedAxeWooden slab (3" thick) 6 30 Axe, hammer, clubWooden pole (1" diameter) 1 3 Any Thin iron/bronze ('/ 8 ") 3 6 Not impalingWooden pole (2" diameter) 3 8 Not impaling Thin iron/bronze ('/ 4 ") 4 12 Axe, hammer, clubWooden pole (3" diameter) 4 12 Edged Iron slab ( 1 / 2 " thick) 6 25 Axe, hammer, clubWooden pole (4" diameter) 6 20 Axe Iron wall (1" thick) 8 50 Axe, hammer, clubWooden pole (6" diameter)Wooden pole (8" diameter)663050AxeAxe Thin steel ('/ 8 ") 4 10 Not impalingThin steel ( 1 / 2 ") 6 20 Axe, hammer, clubBronze/iron bar ( 1 / 2 " diameter) 1 4 Not impaling Steel slab ( 1 / 4 " thick) 7 40 Axe or hammerBronze/iron bar (1" diameter) 3 20 Axe or hammer Steel wall (1" thick) 8 80 AxeBronze/iron bar (2" diameter) 3 60 AxeBrick wall (3" thick) 6 40 Axe, hammer, clubSteel bar ('/ 2 " diameter) 2 6 Axe or hammer Concrete wall (6" thick) 4 60 Axe or hammerSteel bar (1" diameter) 6 25 Axe Stone wall (6" thick) 8 90 Axe or hammerSteel bar (2" diameter) 8 80 Axe Stone wall (12" thick) 8 180 Axe or hammer
