The word comes from the Greek word βόμβος (bombos), an onomatopoetic term with approximately the same meaning as "boom" in English. A nuclear weapon employs chemical-based explosives to initiate a much larger nuclear-based explosion. The term "bomb" is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as bombs. The military use of the term "bomb", or more specifically aerial bomb, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include grenades, shells, depth charges (used in water), warheads when in missiles, or land mines. In unconventional warfare, "bomb" can refer to any of a limitless range of explosive devices used as or offensive weapons. A cannon is any tubular piece of artillery that uses gunpowder or other usually explosive-based propellants to launch a projectile. Cannon vary in calibre, range, mobility, rate of fire, angle of fire, and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. The word cannon is derived from several languages, in which the original definition can usually be translated as tube, cane, or reed. In modern times, cannon has fallen out of common usage, usually replaced by "guns" or "artillery", if not a more specific term, such as "mortar" or "howitzer". First used in China, cannon were among the earliest forms of gunpowder artillery, and over time replaced siege engines—among other forms of aging weaponry—on the battlefield. The first hand cannon appeared during the 1260 Battle of Ain Jalut between the Mamluks and Mongols in the Middle East. The first cannon in Europe were probably used in Iberia, during the Reconquista, in the 13th century, and English cannon were first deployed in the Hundred Years' War, at the Battle of Crécy, in 1346. It was during this period, the Middle Ages, that cannon became standardised, and more effective in both the anti-infantry and siege roles. After the Middle Ages most large cannon were abandoned in favour of greater numbers of lighter, more manoeuverable pieces. In addition, new technologies and tactics were developed, making most defences obsolete; this led to the construction of star forts, specifically designed to withstand artillery bombardment and the associated siege tactics. Cannon also transformed naval warfare in the early modern period, as European navies took advantage of their firepower. As rifling became more commonplace, the accuracy of cannon was significantly improved, and they became deadlier than ever, especially to infantry. In World War I, the majority of all deaths were caused by cannon; they were also used widely in World War II. Most modern cannon are similar to those used in the Second World War, except for heavy naval guns, which have been replaced by missiles. In particular, autocannon have remained nearly identical to their World War II counterparts. Round shot (or solid shot, or a cannonball, or simply ball) is an obsolete solid projectile without explosive charge, fired from a cannon. As the name implies, round shot is spherical; its diameter is slightly less than the bore of the gun it is fired from. Round shot was made in early times from dressed stone, but by the 17th century, from iron. It was used as the most accurate projectile that could be fired by a smooth-bore cannon, used to batter the wooden hulls of opposing ships, fortifications, or fixed emplacements, and as a long-range anti-personnel weapon. Along with pellet shot and grapeshot, round shot was one of the early projectiles used in firearms. Round shot was used by naval guns during most of the age of sail, being replaced after the invention by Benjamin Robins of the extruded bullet around the mid-19th century. Mons Meg with its 22" (56 cm) calibre cannon balls In land battles, round shot would often plough through many ranks of troops, causing multiple casualties. It could bounce when it hit the ground, striking men at each bounce. Round shot has the disadvantages of not being tightly fitted into the bore (to do so would cause jamming). This causes the shot to "rattle" down the gun barrel and leave the barrel at an angle unless wadding or a discarding sabot is used. Round shot has been totally replaced by modern bullets in small arms and by modern shells in artillery. Round shot is used in historical recreations and historical replica weapons. Pellet shot (now simply called 'shot') is still used in shotguns. A cannon is any large tubular firearm designed to fire a heavy projectile over a long distance. They were first used in Europe and China, and were the archetypical form of artillery. Round shot and grapeshot were the early projectiles used in cannon.
