For other uses of the word, see gun (disambiguation)

A gun is a mechanical device that fires projectiles at high velocity, using a propellant such as gun powder or compressed air.

The term gun is often used as a synonym to firearm, but in its more technical usage refers only to artillery that fires projectiles at a high velocity along a flat trajectory, such as field guns, tank guns and anti-tank guns, and naval guns. Howitzers, mortars, and all hand-held firearms are excluded from this definition. The exception to this is the shotgun, which is hand-held, has a smooth bore and fires a cartridge of pellets. In some forms of military training, use of the word "gun" to refer to a rifle is met with severe punishment in order to foster correct terminology (such as in the movie Full Metal Jacket).

See the related article on firearms for information on weapons informally known as guns.

The word gun is also applied to some more or less vaguely gun-like tools, such as staple guns and glue guns.

In a gun-type fission weapon the "gun" is part of a nuclear weapon. The "projectile" is fissile material that is fired and captured inside the device. In the case of nuclear artillery it should not be confused with the gun that fires the whole warhead.
