Shooting Things to Pieces

Objects such as wall panels, thick glass and similar things have an armor rating and durability, just like armor does.
  In order for an attack to be able to break them down, the attack must have the capacity to affect the material. A small antipersonnel weapon will not damage metals and bulkheads, while a carbine might. When the durability is depleted, the object (or the area of an object) will be broken down. There are billions of objects and materials, but instead of providing an exhaustive list we have created three types that you can adapt and use on the fly. Use your judgment when deciding what kinds of attacks might damage the material types. See the gear section for more information on Armor Rating (AR) and Durability (DU).
  Note: When the durability is depleted, it doesn’t necessarily destroy the entire object. If a wall is destroyed when someone takes a sledge hammer to it, it probably means that an opening big enough for a person to slip through has been made and not that the entire inner wall has collapsed. If a hand grenade had caused the destruction, a much larger hole would probably been blown open.
  Indoors housing material (walls, doors, thick wood, furniture, etc.):
AR 2-5, DU 5-20
  Outer housing material (concrete, thin metal sheets, brick, thin inner ship material such as a sleeping bunk door):
AR 4-10/, DU 15-25
  Sturdy indoor ship materials (inner walls, bulkheads):
AR 10-20, DU 25-50
