Close Combat Weapons is a collective term for any implement or weapon that can be used one-handed in an assault. This includes various common melee weapons such as swords, knives, bayonets, maces, clubs and even pistols. It also includes some unorthodox "weapons" such as claws, tails, beaks and teeth.
Specific races have certain preferences for close-combat weapon types. For instance, the Calandrians are known for using various types of axes and blades.
Some races use larger, dual-handed versions of the more command one-handed close combat weapons.
