Rapid-fire weapons are firearms that can fire multiple rounds in quick succession. The two most common examples of rapid-fire weapons are the Uzi and the MACHINEGUN. The Uzi is a submachine gun designed by Uziel Gal in Israel in the 1940s. It is a compact, lightweight weapon that fires 9mm rounds. The MACHINEGUN is a larger, heavier weapon that typically fires rifle rounds. It is usually mounted on a tripod or vehicle for increased accuracy and stability. Both the Uzi and the MACHINEGUN are capable of firing hundreds of rounds per minute.
