SMG is an abbreviation that stands for "Submachine Gun." It refers to a lightweight, compact, and fully automatic firearm designed for close-quarters combat and rapid fire. The SMG is a smaller version of a traditional machine gun with a shorter barrel and reduced overall size.
Typically chambered for pistol cartridges such as 9mm, .45 ACP, or .40 S&W, SMGs are commonly used by military, law enforcement, and special forces units due to their versatility and maneuverability. They are especially favored in situations requiring high firepower within limited spaces, such as urban warfare or building clearing operations.
The main features of an SMG include a selective fire mechanism, allowing the shooter to switch between semi-automatic and fully automatic modes. They also often offer a high rate of fire, typically around 600 to 900 rounds per minute. SMGs generally use detachable magazines with varying capacities, ranging from 10 to 50 rounds.
Due to their compact size and ease of handling, SMGs are highly effective in close-range engagements, offering superior control and rapid target acquisition. However, their effective range is limited compared to rifles or carbines, usually up to 100 meters. SMGs may have a folding stock or be built with a pistol grip and foregrip to enhance stability and control.
Overall, the SMG serves as a highly reliable firearm commonly employed in tactical scenarios that require maximum maneuverability and close-quarters combat proficiency.
