ROUND
A complete assembly of a projectile (with or without fuze), a propellant charge in a cartridge case, and the means of igniting the propellant charge.
PROJECTILE
An object capable of being propelled by a force, normally from a gun, and continuing in motion by virtue of its kinetic energy.
COMPONENT
An item which is an integral part of a system, sub-system or equipment.

Whats a Fuze?
A mechanical Device usually incorporating safety and arming mechanisms with explosive components designed to initiate a train of fire or detonation.
BODY RELIEF
Portion of the shell wall that is machined to a smaller diameter than the actual calibre of the round.
BOOSTER (exploder)
A high explosive intermediary device incorporating a safety arming mechanism, usually a shutter, which amplifies the shock wave from the detonator.
ADAPTOR
An adaptor is a device that is fitted into, on or to an item of ammunition, to allow the fitting of a part or component which would not otherwise fit.
