The 7.5 cm Infanteriegeschütz 37 was an infantry support gun, used by Germany during World War II. The guns were originally designated 7.5 cm PaK 37. The IG 37s were manufactured from carriages of 3.7 cm Pak 36s and a barrel designed originally for the IG 42 infantry support gun. As an anti-tank weapon it used a hollow charge shell with 0.5 kg of explosives to penetrate up to 85 mm (3.3 in) with a velocity of 395 m/s (1,300 ft/s). The first 84 guns were delivered in June 1944. By the end of the war 1,304 guns were operational.
The Škoda 149 mm K series was a line of heavy howitzer designs used by Germany, Turkey, Romania, Slovakia, and Yugoslavia during World War II.
The 15 cm schwere Feldhaubitze 13, was a heavy field howitzer used by Germany in World War I and the beginning of World War II.
The 10 cm Kanone 17 was a field gun used by Germany in World War I and World War II.
The 10 cm schwere Kanone 18 was a field gun used by Germany in World War II. The German army wanted a new 10.5 cm gun as well as 15 cm howitzer which were to share the same carriage. Guns are heavier than howitzers due to the longer barrel. This also led to the 15 cm sFH 18. As such both weapons had a similar weight and could be carried by a similar carriage. By 1926 Krupp and Rheinmetall had specimen designs, and prototypes were ready by 1930, but was not fielded until 1933–34. Both Krupp and Rheinmetall competed for the development contract, but the Wehrmacht compromised and selected Krupp's carriage to be mated with Rheinmetall's gun.
The 4.2 cm Pak 41 was a light anti-tank gun issued to German airborne units in World War II. This gun was externally similar to the 3.7 cm Pak 36, using a modified version of the latter's carriage, but used the squeeze bore principle to boost its velocity, and hence armour-piercing ability. The bore had a diameter of 42 mm (1.7 in) at the chamber, but tapered down to 28 mm (1.1 in) at the muzzle. Production was terminated in June 1942, after the delivery of 313 guns. By November 1943, 47 remained in service.
The 8 cm kanon vz. 30 was a Czech field gun used in World War II. Guns captured after the German invasion of Czechoslovakia in March 1939 were taken into Wehrmacht service as the 8 cm FK 30(t). It was used by a variety of German units during World War II, including I./SS-Artillerie-Abteilung 3 between 1939 and 1940.
The 8 cm Feldkanone M.5 was a field gun used by Austria-Hungary during World War I. It was a conventional design, with its most notable feature being its obsolescent autofrettaged bronze barrel, necessary because Austria-Hungary still had trouble making steel of the proper quality.
The Bofors 12 cm M. 14 was a howitzer used by the Netherlands in World War II as the Lichte Houwitzer 12 cm L 14. Captured guns were given a German designation after the Battle of the Netherlands as the 12 cm leFH 373(h) although it is not certain that they were actually used by German forces.
The Canon de 75 modèle 1905 à tir rapide was a field gun used by Belgium during World War I and World War II.
The Ehrhardt 7.5 cm Model 1901 was a field gun designed and built by the German company Rheinische Metallwaren- und Maschinenfabrik and sold to Norway in 1901. It remained the main field artillery gun of the Norwegian Army until the German invasion of Norway in 1940. The Germans impressed the surviving guns and used them in Norway for the duration of the Second World War. They equipped German units in Norway and were used as coastal artillery guns; a number were even modified for use as anti-tank guns. A dozen guns were transferred by the Norwegian government to Finland during the Winter War and were used by them during the Continuation War as well.
The Krupp 7.5 cm Model 1903 was a field gun used by a number of European armies in both World War I and World War II.
The Cannone da 75/27 modello 06 was a field gun used by Italy during World War I and World War II. It was a license-built copy of the Krupp Kanone M 1906 gun. It had seats for two crewmen attached to the gunshield as was common practice for the period. Captured weapons were designated by the Wehrmacht during World War II as the 7.5 cm Feldkanone 237(i).
The 10.5 cm cannon Model 1927 was a heavy field gun used by the Netherlands and Hungary during World War II. Dutch guns were known as 10-velds. Hungary purchased a license and built them as 31 Ms. Captured weapons were designated by the Wehrmacht as the schwere 10.5 cm Kanone 335(h). Four were bought by the Swedish Coastal Artillery as 10.5 cm kanon m/27s. They were later upgraded to m/34 standard as m/27-34s. They were transferred to the field artillery in 1942. The Dutch appear to have bought guns with both 40 and 42 caliber barrel lengths.
The Solothurn ST-5 is a 20 mm anti-aircraft gun designed by Waffenfabrik Solothurn in Switzerland which ultimately was the design basis for the highly successful 2 cm FlaK 30 series of guns used by Germany in World War II.
Bofors 75 mm and Bofors 80 mm were two closely related designs of anti-aircraft and general-purpose artillery. Less well known than the 40 mm quick-firing AA gun, the gun was nevertheless adopted by armed forces of numerous countries during World War II, including Argentina, China, Dutch East Indies, Finland, Greece, Hungary, Persia and Thailand. It was closely related to the 8.8 cm Flak 18/36/37/41, one of the best-known AA guns of World War II, which was partially based on it. Some pieces captured by the Japanese in China served as the blueprint for the Type 4 75 mm AA Gun, a reverse-engineered clone of the Bofors 75mm gun.
The 7.5 cm Flak. L/60 was a German anti-aircraft gun built during the 1930s and used by Germany in limited numbers during the Second World War. Although not produced in great numbers its features were further developed in the 8.8 cm Flak 18/36/37/41 series of guns.
During World War II, Germany maintained comprehensive lists of enemy weapons which were given designations in German in a system that matched that of German weapons. When these weapons were captured and put into use with German forces they were referred to by these designations.
The Cannone da 75/27 modello 1912 cannon was a piece of horse artillery used by the Royal Italian Army during the First and Second World Wars. The Germans designated captured guns as the 7.5 cm Feldkanone 245(i).
The 8 cm staal is a 19th century Dutch field gun. It replaced the 8 cm A. bronze. The steel barrel and carriage were made by Krupp in Essen, Germany. In turn the 8 cm staal would be replaced by the Krupp 7.5 cm Model 1903. The '8 staal' was hastily brought back into service on the eve of World War II.
