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. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
The MP 40 is a submachine gun chambered for the 9×19mm Parabellum cartridge. It was developed in Nazi Germany and used extensively by the Axis powers during World War II.
The STEN is a family of British submachine guns chambered in 9×19mm which were used extensively by British and Commonwealth forces throughout World War II and the Korean War. They had a simple design and very low production cost, making them effective insurgency weapons for resistance groups, and they continue to see usage to this day by irregular military forces. The Sten served as the basis for the Sterling submachine gun, which replaced the Sten in British service until the 1990s, when it, and all other submachine guns, were replaced by the SA80.
The StG 44 is a German assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44. The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H).
The Suomi KP/-31 is a Finnish submachine gun that was mainly used during World War II. It is a descendant of the M-22 prototype and the KP/-26 production model, which was revealed to the public in 1925. It entered service in Finland in 1931, and remained in use until the 1980s.
The Sterling submachine gun is a British submachine gun (SMG). It was tested by the British Army in 1944–1945, but did not start to replace the Sten until 1953. A successful and reliable design, it remained standard issue in the British Army until 1994, when it began to be replaced by the L85A1, a bullpup assault rifle.
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge.
The MP 18 was a World War I-era submachine gun designed and manufactured by German arms maker Bergman Waffenfabrik. Introduced into service in 1918 by the German Army during World War I as the primary weapon of the Sturmtruppen, assault groups specialized in trench combat, it was arguably the first such weapon used in combat.
Hugo Schmeisser was a German developer of 20th century infantry weapons.
The 9×19mm MP 3008 was a German last ditch submachine gun manufactured towards the end of World War II in early 1945.
The MP34 is a submachine gun (SMG) that was manufactured by Waffenfabrik Steyr as Steyr-Solothurn S1-100 and used by the Austrian Army and Austrian Gendarmerie and subsequently by units of the German Army and the Waffen SS, in World War II. An exceptionally well-made weapon, it was used by some forces well into the 1970s.
Waffenfabrik Bern, also known as W+F Bern, was an arms manufacturer in Bern, Switzerland, which was a government-owned corporation producing firearms for the Swiss Armed Forces.
The 9×25mm Mauser is a cartridge developed for the Mauser C96 service pistol around 1904 by DWM. Mauser pistols in this relatively powerful caliber were primarily intended for export to Africa, Asia, and South America. The 9mm Mauser Export cartridge was produced specifically for Mauser pistols and carbines made from 1904 to 1914 and then later from approximately 1930 to 1945 for submachine guns chambered for this caliber.
An assault rifle is a selective fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles were first put into mass production and accepted into widespread service during World War II. The first assault rifle to see major usage was the German StG 44, a development of the earlier Mkb 42. While immediately after World War II, NATO countries were equipped with battle rifles, the development of the M16 rifle during the Vietnam War prompted the adoption of assault rifles by the rest of NATO. By the end of the 20th century, assault rifles had become the standard weapon in most of the world's armies, replacing full-powered rifles and sub-machine guns in most roles. The two most successful modern assault rifles are the AK-47 and the M16 designs and their derivatives.
The SIG MKMO is a submachine gun produced by Schweizerische Industrie Gesellschaft (SIG) company in Neuhausen from 1933 to 1937. The MKMO – M = Maschinen, K = Karabiner M = Militär, O = Oben – was designed for the military and to increase firepower it had a larger-capacity magazine as well as a longer barrel. Only 1,228 of these guns were produced. It saw limited adoption by Swiss police departments and the Swiss Guard at the Vatican. Finland purchased approximately 282 of the original MKMO variant, which were used by the home guard, supply units and coastal defense forces in the Continuation War.
The 7.63×25mm Mauser round was the original cartridge for the Mauser C96 service pistol. This cartridge headspaces on the shoulder of the case. It later served as the basis for the 7.62mm Tokarev cartridge commonly used in Soviet and Eastern Bloc weapons.
The Lmg.-Pistole Mod. 1941/44 – also known as Furrer MP 41/44, MP41/44 and LMG-Pistole – was the first submachine gun manufactured in Switzerland for the Swiss Army. The weapon used a complicated toggle-operated short recoil mechanism for its operation and it corresponds to that of the Furrer M25, which is why it is also called Lmg.-Pistole.
The Maschinenkarabiner 42(H) or MKb 42(H) (machine carbine Model 1942 (Haenel)) was an early German assault rifle firing an intermediate round of World War II. Designed in 1940-41 by Hugo Schmeisser working for C. G. Haenel Waffen und Fahrradfabrik, several thousand were made and the gun was used on the Eastern Front from 1943.
Adolf Furrer was a Swiss military officer and small arms designer. He used to be the director of the Waffenfabrik Bern and held the rank of Oberstbrigadier in the Swiss Army.
