A firearm is a weapon that fires either single or multiple projectiles propelled at high velocity by the gases produced through rapid, confined burning of a propellant. This process of rapid burning is technically known as deflagration. In older firearms, this propellant was typically black powder, but modern firearms use smokeless powder, cordite, or other propellants.

The term gun is often used as a synonym for firearm, but in specialist use has a restricted sense—referring only to an artillery piece with a relatively high muzzle velocity and a relatively flat trajectory, such as a field gun, a tank gun, an anti-tank gun, or a gun used in the delivery of naval gunfire. Guns are distinct from howitzers and mortars, which have lower muzzle velocities and higher trajectories. Hand-held firearms, like rifles, carbines, pistols and other small firearms are never called "guns" in the restricted sense among specialists.

Accordingly, the term machine gun is not a misnomer. Although such weapons fire small caliber ammunition (generally 14.5 mm or smaller), they nevertheless have a flat projectile trajectory and a beaten zone, just like any other gun. Machine guns can be deployed in direct and indirect fire missions in a manner similar to artillery guns. Additionally, machine guns are crew served weapons, requiring the services of more than one crewman, just like any other gun. Generally, an automatic weapon designed for a single user is referred to as an automatic rifle.
