Ammunition (commonly shortened to ammo) is propellant and projectile, or broadly anything that can be used in combat including bombs, missiles, warheads, landmines, naval mines, and anti-personnel mines. The word comes from the French ''la munition'' which is all material used for war. The collective term for all types of ammunition is munitions. The purpose of ammunition is to project force against a selected target. However, the nature of ammunition use also includes delivery or combat supporting munitions such as pyrotechnic or incendiary compounds. Since the design of the cartridge, the meaning has been transferred to the assembly of a projectile and its propellant in a single package. Ammunition involves the application of fire to targets, general use of weapons by personnel, explosives and propellants, cartridge systems, high explosive projectiles (HE), warheads, shaped charge forms of attack on armour and aircraft, carrier projectiles, fuzes, mortar ammunition, small arms ammunition, grenades, mines, pyrotechnics, improved conventional munitions, and terminally guided munition. == Glossary == * A "round" is a term synonymous with a single cartridge containing a projectile, propellant, primer and casing. *Large caliber cannon often fire explosive-filled projectiles known as shells, non-explosive projectiles may be used for practice (see artillery). * Large numbers of small projectiles intended to be fired all at once in a single discharge are also called shot; hand-held guns designed for this type of ammunition are generally known as shotguns. * Duds are fully loaded ordnance that fail to function as intended. A cartridge that fails to fire in the weapon is known as a misfire. A partially functioning round is named a hang fire. Dud ammunition, unexploded ordnance (UXO), is regarded as highly dangerous, and most safety officials inform civilians to report finding of any large-bore duds to the local police or military. * Dum-dum rounds were early attempts to cause contact-initiated expansion. Many were leadnose bullets with "X" marks cut across the nose. * A "bomb" or more specifically a guided or unguided bomb (also called aircraft bombs or aerial bombs) typically refers to airdropped, unpowered explosive weapons. Mines, warheads used in guided missiles and rockets are also referred to as bomb-type ammunition.〔(【引用サイトリンク】url=http://www.usna.edu/Training/_files/documents/References/2C%20MQS%20References/NAVEDTRA%2014014A%20Ch.%209%20Aircraft%20Ordnance.pdf )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ammunition」の詳細全文を読む スポンサード リンク
