Weapon
A weapon is a tool which can be used during combat to kill or incapacitate, to destroy property, or to otherwise render resources non-functional or unavailable. It may be used to attack and defend, and consequently also to threaten or protect. There are essentially three facets to classifying weapon types: who uses it, how it works, and what it targets.
