What is another word for automatic firearm?
Pronunciation: [ˌɔːtəmˈatɪk fˈa͡ɪ͡əɹɑːm] (IPA) 
Automatic firearm is a broad term that describes a variety of gun types that have the ability to shoot multiple rounds with just one trigger pull. Some synonyms for automatic firearms include machine guns, assault rifles, submachine guns, and fully-automatic weapons. Machine guns were originally designed for military use and were capable of firing hundreds of rounds per minute. Assault rifles are a type of automatic firearm that are designed to be lightweight and highly maneuverable, making them ideal for use in close-quarters combat situations. Submachine guns are typically smaller versions of machine guns and are often used by law enforcement agencies. Fully-automatic weapons are sometimes used interchangeably with machine guns, but technically, they are a subset of automatic firearms that can fire continuously as long as the trigger is held down.
