What is a machine gun?

Machine guns are fully automatic firearms designed to continuously fire bullets as long as the trigger is held down and there is ammunition in the feed system. They are typically used by military and law enforcement agencies for suppressive fire and defense purposes. Machine guns come in various types, such as light, medium, and heavy, and are often mounted on vehicles or tripods for stability due to their rapid rate of fire. Their use and ownership are heavily regulated in most countries due to their destructive potential.
