Jagdpanzer IV
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 (tank destroyer, literally "hunting tank") designs, it was developed against the wishes of Heinz Guderian, the inspector general of the ''Panzertruppen'', as a replacement for the ''Sturmgeschütz III'' (''StuG'' 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. Officially, only the L/48-armed vehicle was named Jagdpanzer IV. The L/70-armed vehicle was named Panzer IV/70. In this article, both versions are referred to in general as Jagdpanzer IV, except in the variants and surviving vehicles section. Development With experience gained during the initial phases of the Battle of Stalingrad, in September 1942 the Wehrmacht's arms bureau, the ''Waffenamt'', called for a new standard for ...

KwK 42
The 7.5 cm KwK 42 L/70 (from 7.5 cm ''Kampfwagenkanone'' 42 L/70) was a 7.5 cm calibre German tank gun used on German armoured fighting vehicles in the Second World War. The gun was the armament of the Panther medium tank and two variants of the Jagdpanzer IV self-propelled anti-tank gun. On the latter it was designated as the "7.5 cm ''Panzerabwehrkanone'' 42" (7.5 cm Pak 42) anti-tank gun. Design The increased muzzle velocity and operating pressure of the new gun required a new armour-piercing projectile to be designed. The PzGr. 39/42 was the result, and apart from the addition of wider driving bands it was otherwise identical to the older 7.5 cm PzGr. 39. The wider driving bands added a little extra weight, from 6.8 kg for the old PzGr.39, to 7.2 kg for the new PzGr.39/42.US Army Technical Manual TM9-1985-3, United States Government Printing Office Washington, 1953 The gun was fired electrically, the primer being initiated using an el ...

Nibelungenwerk
The Nibelungenwerk (also known as the Nibelungenwerke or Ni-Werk) was the largest and most modern tank assembly factory in Nazi Germany, located near the Austrian town of St. Valentin. As the only German tank production facility which had a well-structured production line, the Nibelungenwerk produced more than half of all of Nazi Germany's Panzer IV tanks. History The Nibelungenwerk was built as part of the Four Year Plan after the Anschluss as part of an armaments centre, along with the Eisenwerke Oberdonau. There had been plans dating back to 1939 to build an armaments plant in the Herzograd Forest near the Lower Austrian community of Sankt Valentin, which was conveniently located at a railway junction. The construction cost of 65 million Reichsmarks was paid by the Reichswerke Hermann Göring and the factory was from the outset very generously specified. Although the bulk of new construction projects for the armaments industry were frozen at the time, that did not affect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Kursk
The Battle of Kursk was a major World War II Eastern Front engagement between the forces of Nazi Germany and the Soviet Union near Kursk in the southwestern USSR during late summer 1943; it ultimately became the largest tank battle in history. The battle began with the launch of the German offensive Operation Citadel (german: Unternehmen Zitadelle), on 5 July, which had the objective of pinching off the Kursk salient with attacks on the base of the salient from north and south simultaneously. After the German offensive stalled on the northern side of the salient, on 12 July the Soviets commenced their Kursk Strategic Offensive Operation with the launch of Operation Kutuzov (russian: Кутузов) against the rear of the German forces on the same side. On the southern side, the Soviets also launched powerful counterattacks the same day, one of which led to a large armoured clash, the Battle of Prokhorovka. On 3 August, the Soviets began the second phase of the Kursk Strategi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG 34
The MG 34 (shortened from German: ''Maschinengewehr 34'', or "machine gun 34") is a German recoil-operated air-cooled general-purpose machine gun, first tested in 1929, introduced in 1934, and issued to units in 1936. It introduced an entirely new concept in automatic firepower – the ''Einheitsmaschinengewehr'' (Universal machine gun) – and is generally considered the world's first general-purpose machine gun (GPMG). Both the MG 34 and MG 42 were erroneously nicknamed "Spandau" by Allied troops, a carryover from the World War I nickname for the MG 08, which was produced at the Spandau Arsenal. The versatile MG 34 was chambered for the full-power 7.92×57mm Mauser rifle cartridge, and was arguably the most advanced machine gun in the world at the time of its deployment. The MG 34 was envisaged and well developed to provide portable light and medium machine gun infantry cover, anti-aircraft coverage, and even sniping ability. Its combination of exceptional mobility – being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handedness
In human biology, handedness is an individual's preferential use of one hand, known as the dominant hand, due to it being stronger, faster or more Fine motor skill, dextrous. The other hand, comparatively often the weaker, less dextrous or simply less subjectively preferred, is called the non-dominant hand. In a study from 1975 on 7688 children in US grades 1-6, Left handers comprised 9.6% of the sample, with 10.5% of male children and 8.7% of female children being left-handed. Handedness is often defined by one's writing hand, as it is fairly common for people to prefer to do some tasks with each hand. There are examples of true ambidexterity (equal preference of either hand), but it is rare—most people prefer using one hand for most purposes. Most of the current research suggests that left-handedness has an epigenetic marker—a combination of genetics, biology and the environment. Because the vast majority of the population is right-handed, many devices are designed for u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firing Port
A firing port, sometimes called a pistol port, is a small opening in armored vehicles, fortified structures like bunkers, or other armored equipment that allows small arms to be safely fired out of the vehicle at enemy infantry, often to cover vehicle or building blindspots. Examples of this can be seen in the Crusader tank, Sherman tank, Tiger I, T-34-85, and even modern armored vehicles today such as the Mechanized Infantry Combat Vehicle (MICV) program, its successor the Bradley Fighting Vehicle (BFV) featuring the M231 Firing Port Weapon, and Russian armored personnel carriers. Some firing ports are improvised for such use. For example a late production Tiger I manual shows the Nahverteidigungswaffe being used as a firing port. Some pistol ports, such as on the Sherman, included vision slits such as "protectoscopes" increasing visibility around the tank. Ballistic weakspot Being a ballistic weak spot, firing ports are often reinforced with additional armor, and in sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jagdpanzer IV Prototyp (39076253362)
''Jagdpanzer'' (JgPz) is the name given in German to a heavily-armoured, tracked tank destroyer, although it may also be used for other kinds of self-propelled guns. Literally translated from German, ''Jagdpanzer'' is "hunting tank". It typically refers to anti-tank variants of existing tank chassis with a well-armoured casemate fixed superstructure, mounting an anti-tank gun with limited traverse in the front, and classed by the western Allies of World War II as a tank destroyer. History The ''Jagdpanzer'' designs followed on from the more lightly armoured ''Panzerjäger'' ("tank hunter") designs, which took an anti-tank gun and mounted it on top of a tank chassis with supplementary armour fitted around the gun crew. However, the armour had an open rear and top, almost never providing the crew with full protection from the elements. In addition, much experience was gained from the Sturmgeschütz series of assault guns for infantry support, which already used heavily armoured ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article on Limcat Under ...
