An assault gun is a type of self-propelled artillery which uses an infantry support gun mounted on a motorized chassis, normally an armored fighting vehicle, which are designed to provide direct fire support for infantry attacks, especially against other infantry or fortified positions. Assault guns were pioneered by the Soviet Union and Nazi Germany during the 1930s, initially being self-propelled guns with direct fire in mind, with Germany introducing the first purpose-built assault gun, the Sturmgeschütz III, in 1940.
A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities.
Self-propelled artillery is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield.
The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman.
The Combat Vehicle 90 (CV90) is a family of Swedish tracked armoured combat vehicles designed by the Swedish Defence Materiel Administration (FMV), Hägglunds and Bofors during the mid-1980s to early 1990s, before entering service in Sweden in the mid-1990s. The CV90 platform design has continuously evolved from the Mk 0 to the current Mk IV with technological advances and changing battlefield requirements. The Swedish version of the main infantry fighting vehicle (IFV) is fitted with a turret from Bofors equipped with a 40 mm Bofors autocannon. Export versions are fitted with Hägglunds E-series turrets, armed with either a 30 mm Mk44 or a 35 mm Bushmaster autocannon.
The Bofors 40 mm Automatic Gun L/60 is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability.
The Bofors 37 mm anti-tank gun was an anti-tank gun designed by Swedish manufacturer Bofors in the early 1930s originally for Swedish use. It was exported to several countries during the 1930s of which several bought licences to produce it themselves. The gun was used in several conflicts but most of its fame comes from its use in the Spanish Civil War and the Winter War where it was used very successfully against light tanks and armored cars among other targets. Beyond its use as an infantry gun it was also used as the main armament in several armored cars and tanks such as the Dutch M39 Pantserwagen and the Polish 7TP to name a few. As the armor of tanks was increased during World War II the gun very quickly became obsolete as an anti-tank gun but was still used effectively as an infantry support gun for the entirety of the war, and well into the Cold War. This was due to its high fire rate, great mobility and effective high explosive shells.
An anti-tank gun is a form of artillery designed to destroy tanks and other armoured fighting vehicles, normally from a static defensive position. The development of specialized anti-tank munitions and anti-tank guns was prompted by the appearance of tanks during World War I. To destroy hostile tanks, artillerymen often used field guns depressed to fire directly at their targets, but this practice expended too much valuable ammunition and was of increasingly limited effectiveness as tank armor became thicker. The first dedicated anti-tank artillery began appearing in the 1920s, and by World War II was a common appearance in many European armies. To penetrate armor, they fired specialized ammunition from longer barrels to achieve a higher muzzle velocity than field guns. Most anti-tank guns were developed in the 1930s as improvements in tanks were noted, and nearly every major arms manufacturer produced one type or another.
The M36 tank destroyer, formally 90 mm Gun Motor Carriage, M36, was an American tank destroyer used during World War II. The M36 combined the hull of the M10 tank destroyer, which used the M4 Sherman's reliable chassis and drivetrain combined with sloped armor, and a new turret mounting the 90 mm gun M3. Conceived in 1943, the M36 first served in combat in Europe in October 1944, where it partially replaced the M10 tank destroyer. It also saw use in the Korean War, where it was able to defeat any of the Soviet tanks used in that conflict. Some were supplied to South Korea as part of the Military Assistance Program and served for years, as did re-engined examples found in Yugoslavia, which operated into the 1990s. Two remained in service with the Republic of China Army at least until 2001.
A tank gun is the main armament of a tank. Modern tank guns are high-velocity, large-caliber artilleries capable of firing kinetic energy penetrators, high-explosive anti-tank, and cannon-launched guided projectiles. Anti-aircraft guns can also be mounted to tanks.
The Jagdpanzer IV, Sd.Kfz. 162, was a German tank destroyer based on the Panzer IV chassis and built in three main variants. As one of the casemate-style turretless Jagdpanzer designs, it was developed against the wishes of Heinz Guderian, the inspector general of the Panzertruppen, as a replacement for the Sturmgeschütz III. Guderian objected against the needless, in his eyes, diversion of resources from Panzer IV tank production, as the StuG III was still more than adequate for its role.
The Turán tanks were a series of Hungarian medium tanks of World War II. They were produced in two main variants: the original 40M Turán with a 40 mm gun and later the 41M Turán with a short-barreled 75 mm gun, improved armour and a new turret. A total of 285 40M Turán I tanks were made. The 40M Turán was originally inspired by and used the features found on the design of the Czechoslovak Škoda T-21 medium tank prototype. The Turán tanks fought on the Eastern Front against the Soviets, and in the defence of Hungary.
The M10 tank destroyer was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942 and delivered in April that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1942 as the 3-inch Gun Motor Carriage M10. It mounted a 3-inch gun M7 in a rotating turret on a modified M4 Sherman tank chassis. An alternate model, the M10A1, which used the M4A3 variant chassis, was also produced. Production of the two models ran from September 1942 to December 1943 and October 1942 to November 1943, respectively.
The 37 mm gun M3 is the first dedicated anti-tank gun fielded by United States forces in numbers. Introduced in 1940, it became the standard anti-tank gun of the U.S. infantry with its size enabling it to be pulled by a jeep. However, the continuing improvement of German tanks quickly rendered the 37 mm ineffective and, by 1943, it was being gradually replaced in the European and Mediterranean theaters by the more powerful British-developed 57 mm gun M1. In the Pacific, where the Japanese tank threat was less significant, the M3 remained in service until the end of the war, but some 57mm guns were issued.
The 76 mm gun M1 was an American World War II–era tank gun developed by the U.S United States Ordnance Department in 1942 to supplement the 75 mm gun on the basic Medium tank M4. It was also used to arm the M18 Hellcat tank destroyer.
Stridsvagn m/41 was a Swedish medium tank. A license-built version of the Czechoslovak TNH medium tank, it served into the 1950s.
The 40M Nimród was a World War II Hungarian self-propelled anti-aircraft gun based on a license-built copy of the Swedish Landsverk L-62 Anti I SPAAG but with a new turret, and developed independently. Originally, it was intended to be used both in the anti-aircraft and tank destroyer roles, but it proved to be ineffective against heavily armored Soviet tanks like the KV-1. Therefore, it was primarily utilized against lightly armored vehicles and for air defense.
Bofors 57 mm Naval Automatic Gun L/60, also known as 57 mm/60 (2.25") SAK Model 1950 and the like, was a twin-barreled 57 mm (2.2 in) caliber fully automatic dual purpose naval artillery piece designed by the Swedish arms manufacturer Bofors from the early of the 1940s to the early 1950s to meet a request from the Dutch Navy. Besides the Dutch Navy, the weapon was also adopted by the Swedish and the French Navy, most predominantly by the latter.
The 44M Tas was a Hungarian heavy tank/medium tank design of World War II. It was developed to combat heavily armored Soviet tanks encountered on the Eastern Front and to replace the older Turán I and Turán II tanks which Hungary operated, modernising Hungary's armoured forces. The Tas somewhat resembled the German Panther tank in terms of both looks and capabilities. It was to be well armored – up to 120 mm thick and with sloped armor. The main armament would likely have been a Hungarian built heavily modified anti-tank version of the 80 mm Bofors AA gun. The only prototypes built were destroyed when the Americans bombed the Weiss Manfréd factory in July 1944.
