1. Submachine gun

   A submachine gun (SMG) is a magazine-fed, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix "sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of SMGs were made for use by regular troops, clandestine commandos, and partisans alike. After the war, new SMG designs appeared frequently. However, by the 1980s and 1990s, SMG usage decreased. Today, submachine guns have been largely replaced by assault rifles, which have a longer 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 and police SWAT teams for close-quarters battle (CQB) because they are "a pistol-caliber weapon that's easy to control, and less likely to overpenetrate the target".

1. Submachine gun

   A submachine gun is an automatic carbine, designed to fire pistol cartridges. It combines the automatic fire of a machine gun with the cartridge of a pistol. The submachine gun was invented during World War I. The zenith of its use was World War II when millions of weapons of this type were manufactured. In military use, the submachine gun has been supplanted in general issue by carbine-length assault rifles firing intermediate cartridges due to their superior range and power; submachine guns have poor accuracy past 50m and are generally unable to penetrate the improved ballistic helmets and body armor increasingly becoming standard-issue for modern infantrymen. However, submachine guns retain widespread use in police SWAT and domestic counter-terrorist forces, who value the SMG's lighter recoil, better accuracy in burst or fully automatic mode and minimized bullet overpenetration when dealing with residential hostage crises, high-risk search/arrest warrants and other domestic situations in tight quarters where innocent civilian casualties are a major concern. There is some categorical inconsistency with regard to the classification of submachine guns; for example, some sources consider personal defense weapons—particularly short carbines firing a rifle cartridge —to be submachine guns. Most sources now, however, restrict the term solely to pistol-caliber, carbine-length automatic weapons. Fully automatic pistols designed to be fired one-handed are known as machine pistols, a term which also formerly included many submachine guns.
