Pz.Sfl. II
The ''Panzer-Selbstfahrlafette'' II , or in full, 7.5 cm ''Kanone'' L/41 ''auf Zugkraftwagen'' 5t (HKp 902), was a half-track German tank destroyer used during World War II. Only two prototypes were built and sent to North Africa for troop trials. Neither survived the war. Design and description Development began in 1936 when Büssing-NAG was given a contract to develop an advanced half-track chassis with a rear-mounted engine specifically designed for use as a tank destroyer. Four prototypes of the HKp 902 chassis were built, two of which had Rheinmetall-Borsig's L/40.8 gun mounted in an open-topped, low-profile turret. The gun had an elevation range between −8° and +20°. It fired a ''K.Gr. rot Pz.'' ( APCBC) shell with a muzzle velocity of and a ''Sprenggranate'' ( HE) shell at . It carried 35 rounds on board. The armor protection, designed to be proof against armour-piercing bullets, was thick on the vehicle's front, and on the sides, on the rear, on ...

Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APCBC
Armour-piercing, capped, ballistic capped (APCBC) is a type of configuration for armour-piercing ammunition introduced in the 1930s to improve the armour-piercing capabilities of both naval and anti-tank guns. The configuration consists of an armour-piercing shell fitted with a stubby ''armour-piercing cap'' (AP cap) for improved penetration properties against surface hardened armour, especially at high impact angles, and an aerodynamic ''ballistic cap'' on top of the AP cap to correct for the poorer aerodynamics, especially higher drag, otherwise created by the stubby AP cap. These features allow APCBC shells to retain higher velocities and to deliver more energy to the target on impact, especially at long range when compared to uncapped shells. The configuration is used on both inert and explosive armour-piercing shell types: *Armour-piercing (AP), capped, ballistic capped (APCBC) * Semi-armour-piercing (SAP), capped, ballistic capped (SAPCBC) *Armour-piercing, high-explosive ( ...

Battle Of Gazala
The Battle of Gazala (near the village of ) was fought during the Western Desert Campaign of the Second World War, west of the port of Tobruk in Libya, from 26 May to 21 June 1942. Axis troops of the ( Erwin Rommel) consisting of German and Italian units fought the British Eighth Army (General Sir Claude Auchinleck, also Commander-in-Chief Middle East) composed mainly of British Commonwealth, Indian and Free French troops. The Axis troops made a decoy attack in the north as the main attack moved round the southern flank of the Gazala position. Unexpected resistance at the south end of the line around the Bir Hakeim box by the Free French garrison, left with a long and vulnerable supply route around the Gazala Line. Rommel retired to a defensive position backing onto Allied minefields (the Cauldron), forming a base in the midst of the British defences. Italian engineers lifted mines from the west side of the minefields to create a supply route through to the Axis side. Ope ...

Operation Venezia
Operation Venezia was a Second World War operation in which Erwin Rommel moved a large portion of his forces around Bir Hakeim Bir Hakeim ( ar, بئر حكيم, translit=biʾr ḥakīm, lit=Wise Well ; sometimes written ''Bir Hacheim'') is in the Libyan desert at and is the site of a former Ottoman Empire fort built around the site of an ancient Roman well, dating to ..., the southernmost part of the British Gazala Line, soon after the start of the Battle of Gazala. Rommel activated the operation at 20:30The Rommel Papers, pg.206 on 26 May 1942, after his reconnaissance confirmed the presence of strong British armoured formations north-east of Bir Hakeim. His encircling force consisted of 10,000 vehicles from the 15. and 21. ''Panzerdivision''s, the Italian ''Ariete'' Armoured Division and the motorized elements of the German 90th Light Infantry Division. The British forces were expecting Rommel to make an attack and, on intercepting a signal which contained the codewor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrika Korps
The Afrika Korps or German Africa Corps (, }; DAK) was the German expeditionary force in Africa during the North African Campaign of World War II. First sent as a holding force to shore up the Italian defense of its African colonies, the formation fought on in Africa, under various appellations, from March 1941 until its surrender in May 1943. The unit's best known commander was Field Marshal Erwin Rommel. History Organization The Afrika Korps formed on 11 January 1941 and one of Hitler's favourite generals, Erwin Rommel, was designated as commander on 11 February. Originally Hans von Funck was to have commanded it, but Hitler loathed von Funck, as he had been a personal staff officer of Werner von Fritsch until von Fritsch was dismissed in 1938. The German Armed Forces High Command ('' Oberkommando der Wehrmacht'', OKW) had decided to send a "blocking force" to Italian Libya to support the Italian army. The Italian 10th Army had been routed by the British Commonwealth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''supersonic'' and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the shot. Projec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevation (ballistics)
In ballistics, the elevation is the angle between the horizontal plane and the axial direction of the barrel of a gun, mortar or heavy artillery. Originally, elevation was a ''linear'' measure of how high the gunners had to physically lift the muzzle of a gun up from the gun carriage to compensate for projectile drop and hit targets at a certain distance. Until WWI Though early 20th-century firearms were relatively easy to fire, artillery was not. Before and during World War I, the only way to effectively fire artillery was plotting points on a plane. Most artillery units seldom employed their guns in small numbers. Instead of using pin-point artillery firing they used old means of " fire for effect" using artillery en masse. This tactic was employed successfully by past armies. By World War I, reasonably accurate artillery fire was possible even at long range requiring significant elevation. However, artillery tactics used in previous wars were carried on, and still had simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tank Destroyer
A tank destroyer, tank hunter, tank killer, or self-propelled anti-tank gun is a type of armoured fighting vehicle, armed with a direct fire artillery gun or missile launcher, designed specifically to engage and destroy enemy tanks, often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a tracked tank chassis, while others are wheeled. Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the first two decades of the 21st century has s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half-track
A half-track is a civilian or military vehicle with regular wheels at the front for steering and continuous tracks at the back to propel the vehicle and carry most of the load. The purpose of this combination is to produce a vehicle with the cross-country capabilities of a tank and the handling of a wheeled vehicle. Performance The main advantage of half-tracks over wheeled vehicles is that the tracks reduce the pressure on any given area of the ground by spreading the vehicle's weight over a larger area, which gives it greater mobility over soft terrain like mud and snow, while they do not require the complex steering mechanisms of fully tracked vehicles, relying instead on their front wheels to direct the vehicle, augmented in some cases by track braking controlled by the steering wheel. It is not difficult for someone who can drive a car to drive a half-track, which is a great advantage over fully tracked vehicles, which require specialized training. Half-tracks thus facil ...
