 30 (short for "ciężki karabin maszynowy wz.
 30"; "heavy machine gun 1930 Pattern") is a Polish-made clone of the American Browning M1917 heavy machine gun.
 Produced with various modifications such as greater caliber, longer barrel and adjustable sighting device, it was an improved although unlicensed copy of its predecessor, and was the standard machine gun of the Polish Army since 1931.
The Type 97 heavy tank machine gun (九七式車載重機関銃 , Kyū-nana-shiki shasai jū-kikanjū ) was the standard machine gun used in tanks and armored vehicles of the Imperial Japanese Army during World War II, a heavy machine gun by infantry forces, This weapon was not related to the Type 97 aircraft machine gun used in several Japanese Navy aircraft including the A6M Zero.
The Flieger MG 29 (also called the Flab MG or FLab MG 29/38) was a Swiss light machine gun developed in the 1920s and produced until shortly before the dawn of the Second World War.
 It was mounted on aircraft and was later used as an anti-aircraft gun.
 However, it was too heavy to be used as am infantry support weapon.
 It employed a closed bolt system.
 Some guns had the ability to bolt a large box onto the bottom of the machine gun to hold the ammunition belt.
 Two versions of the gun existed, the "normal" version and a second version which bolted two guns together and made them to fire from the same trigger, known as the "Doppel-MG" (double machine gun).
 After the second world war, better anti aircraft systems and aircraft weapons were available to Switzerland and the infantry support role was filled by the MG 51.
 The higher rate of fire, but much heavier MG 29 was finally mounted on the first prototype of the Panzer 58, the precursor to the more famous Panzer 61 tank before being retired.
The Maschinengewehr Modell 1911 or MG 11 is a Swiss heavy machine gun which was introduced before and during World War I.
 The MG 11 has a narrow constructive relationship with the German MG 08 heavy machine gun.
The Type 1 machine gun was developed for aerial use for the Imperial Japanese Army and Navy during World War II.
 It was an adaptation of the German MG 15 machine gun.
 (Note that the 12.7mm Ho-103 and H-104 machine guns are also known as the "Type 1 machine gun", but are actually a 12.7mm adaption of the Browning M1919 machine gun in fixed and flexible mountings, respectively.)
08/15 is a 1954–55 West German film trilogy directed by Paul May and based on the novel "08/15" by Hans Hellmut Kirst who also served as the film's screenwriter (published in English as "The Revolt of Gunner Asch").
 The term "08/15" (nill-eight/fifteen, German: "Null-Acht/Fünfzehn" ) refers to the German Army's standard machine gun, the 08/15 (or MG 08 model 15), by far, the most common German machine gun deployed in World War I.
 It was manufactured in such large quantities that it became the German Army slang for anything that was standard issue.
The "Maschinengewehr" 08, or MG 08, was the German Army's standard machine gun in World War I and is an adaptation of Hiram S. Maxim's original 1884 Maxim gun.
 It was produced in a number of variants during the war.
 The MG 08 served during World War II as a heavy machine gun in many German infantry divisions, although by the end of the war it had mostly been relegated to second-rate fortress units.
The MG 17 was a 7.92 mm machine gun produced by Rheinmetall-Borsig for use at fixed mountings in many World War II Luftwaffe aircraft, typically as forward-firing offensive armament, but also used as fixed, remotely-fired tail guns in certain aircraft variants, such as the Do 217.
 The MG 17 was based on the older MG 30 light machine gun, as was its defensive flexible-mount counterpart, the MG 15 machine gun, which was of the same caliber and general size.
 Modifications to the design included removal of the buttstock, switching from magazine to belt-fed ammunition, and from open-bolt operation to closed bolt operation, to allow it to be installed in synchronized applications, firing through the propeller arc.
 The MG 15 retained open bolt operation, but used 75 round saddle-type drum magazines, and likewise lost its buttstock, to fit better in the tight confines of an aircraft.
 The MG 30 was also the basis for the famed MG 34 and MG 42 designs; variants of the latter are still in service in certain areas.
The 7.5 mm Maschinengewehr 1951 or Mg 51 is a general-purpose machine gun manufactured by W+F of Switzerland.
 The weapon was introduced into Swiss service when the Swiss Army initiated a competition for a new service machine gun to replace the MG 11 heavy machine gun and the Furrer M25 light machine gun adopted in 1911 and 1925 respectively.
08/15 is a 1954 West German film directed by Paul May and based on the novel "08/15" by Hans Hellmut Kirst who also served as the film's screenwriter.

 It was manufactured in such large quantities that it became the German Army slang for anything that was standard issue.
 08/15 is also the first part of the 08/15 film trilogy, hence it is also named "Teil 1: In der Kaserne" ("Part 1: In the Barracks").
