Submachine guns

Submachine guns(Also abbreviated as SMGs) are a class of magazine-fed, automatic carbines designed to shoot handgun cartridges. Submachine guns are largely replaced by assault rifles, which have a greater effective range and are capable of penetrating the helmets and body armor used by modern infantry. However, submachine guns are still used by military special forces for close quarters battle (CQB) because they are a pistol-caliber weapon that is easy to control, and less likely to over-penetrate the target.
