Ancillary weapon

An ancillary weapon is a weapon used for secondary or auxiliary purpose, such as a bayonet. Such weapons are usually equipped with less firepower than the primary weapon. The usage of ancillary weapons most frequently occurs when the primary weapon becomes inoperable or ineffective due to shortage of ammunition or when a battle becomes a Close Quarters Battle. Many modern weapons/vehicles are equipped with ancillary weapons, including tanks or even the SA80.
