Eastern Front (World War II)
–
The battles on the Eastern Front constituted the largest military confrontation in history. They were characterized by unprecedented ferocity, wholesale destruction, mass deportations, and immense loss of life due to combat, starvation, exposure, disease, and massacres. The Eastern Front, as the site of nearly all extermination camps, death marches, ghettos, of the estimated 70 million deaths attributed to World War II, over 30 million, many of them civilian, occurred on the Eastern Front. The Eastern Front was decisive in determining the outcome of the European portion of World War II and it resulted in the destruction of the Third Reich, the partition of Germany for nearly half a century and the rise of the Soviet Union as a military and industrial superpower. The two principal belligerent powers were Nazi Germany and the Soviet Union, along with their respective allies. Though never engaged in action in the Eastern Front, the United Kingdom. The joint German–Finnish operations across the northernmost Finnish–Soviet border and in the Murmansk region are considered part of the Eastern Front, in addition, the Soviet–Finnish Continuation War may also be considered the northern flank of the Eastern Front. Despite their ideological antipathy, both Nazi Germany and the Soviet Union shared a dislike for the outcome of World War I. The Molotov–Ribbentrop Pact signed in August 1939 was an agreement between Nazi Germany and the Soviet Union. It contained a secret protocol aiming to return Central Europe to the pre–World War I status quo by dividing it between Germany and the Soviet Union, Finland, Estonia, Latvia and Lithuania would return to Soviet control, while Poland and Romania would be divided. I need the Ukraine so that they cant starve us out, the two powers invaded and partitioned Poland in 1939. The annexations were never recognized by most Western states, the annexed Romanian territory was divided between the Ukrainian and Moldavian Soviet republics. Adolf Hitler had argued in his autobiography Mein Kampf for the necessity of Lebensraum, acquiring new territory for Germans in Eastern Europe, Wehrmacht officers told their troops to target people who were described as Jewish Bolshevik subhumans, the Mongol hordes, the Asiatic flood and the red beast. The vast majority of German soldiers viewed the war in Nazi terms, Hitler referred to the war in unique terms, calling it a war of annihilation which was both an ideological and racial war. In addition, the Nazis also sought to wipe out the large Jewish population of Central, after Germanys initial success at the Battle of Kiev in 1941, Hitler saw the Soviet Union as militarily weak and ripe for immediate conquest. On 3 October 1941, he announced, We have only to kick in the door, thus, Germany expected another short Blitzkrieg and made no serious preparations for prolonged warfare. Throughout the 1930s the Soviet Union underwent massive industrialization and economic growth under the leadership of Joseph Stalin, Stalins central tenet, Socialism in one country, manifested itself as a series of nationwide centralized Five-Year Plans from 1929 onwards. It served as a testing ground for both the Wehrmacht and the Red Army to experiment with equipment and tactics that they would later employ on a wider scale in the Second World War

Howitzer
–
In the taxonomies of artillery pieces used by European armies in the 17th to 20th centuries, the howitzer stood between the gun and the mortar. Howitzers, like other artillery equipment, are organized in groups called batteries. The English word howitzer comes from the Czech word houfnice, from houf, crowd, haufen, sometimes in the compound Gewalthaufen, also designated a pike square formation in German. This is particularly true in the forces of the United States. Because of this practice, the howitzer is used in some armies as a generic term for any kind of artillery piece that is designed to attack targets using indirect fire. Thus, artillery pieces that bear resemblance to howitzers of earlier eras are now described as howitzers. Most other armies in the reserve the word howitzer for guns with barrel lengths 15 to 25 times their caliber. The British had a method of nomenclature. In the 18th century, they adopted projectile weight for guns replacing the old naming system of culverin, saker, mortars had been categorized by calibre in inches in the 17th century and this was inherited by howitzers. The modern howitzers were invented in Sweden towards the end of the 17th century, originally intended for use in siege warfare, they were particularly useful for delivering cast-iron shells filled with gunpowder or incendiary materials into the interior of fortifications. In the middle of the 18th century, a number of European armies began to introduce howitzers that were enough to accompany armies in the field. Though usually fired at the high angles of fire used by contemporary siege howitzers. Rather, as the guns of the day were usually restricted to inert projectiles. Many, for the sake of simplicity and rapidity of fire, the Abus gun was an early form of howitzer in the Ottoman Empire. In 1758 the Russian Empire introduced a type of howitzer, with a conical chamber, called a licorne. The most famous of these gun-howitzers was the Napoleon 12-pounder, a weapon of French design that saw service in the American Civil War. The longest-serving artillery piece of the 19th century was the mountain howitzer, in 1859, the armies of Europe began to rearm field batteries with rifled field guns. These new field pieces used cylindrical projectiles that, while smaller in caliber than the spherical shells of smoothbore field howitzers, moreover, their greater range let them create many of the same effects that previously required the sharply curved trajectories of smoothbore field howitzers

Nazi Germany
–
Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party. Under Hitlers rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over all aspects of life. The official name of the state was Deutsches Reich from 1933 to 1943, the period is also known under the names the Third Reich and the National Socialist Period. The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, Hitler was appointed Chancellor of Germany by the President of the Weimar Republic Paul von Hindenburg on 30 January 1933. The Nazi Party then began to eliminate all opposition and consolidate its power. Hindenburg died on 2 August 1934, and Hitler became dictator of Germany by merging the powers and offices of the Chancellery, a national referendum held 19 August 1934 confirmed Hitler as sole Führer of Germany. All power was centralised in Hitlers person, and his word became above all laws, the government was not a coordinated, co-operating body, but a collection of factions struggling for power and Hitlers favour. In the midst of the Great Depression, the Nazis restored economic stability and ended mass unemployment using heavy military spending, extensive public works were undertaken, including the construction of Autobahnen. The return to economic stability boosted the regimes popularity, racism, especially antisemitism, was a central feature of the regime. The Germanic peoples were considered by the Nazis to be the purest branch of the Aryan race, millions of Jews and other peoples deemed undesirable by the state were murdered in the Holocaust. Opposition to Hitlers rule was ruthlessly suppressed, members of the liberal, socialist, and communist opposition were killed, imprisoned, or exiled. The Christian churches were also oppressed, with many leaders imprisoned, education focused on racial biology, population policy, and fitness for military service. Career and educational opportunities for women were curtailed, recreation and tourism were organised via the Strength Through Joy program, and the 1936 Summer Olympics showcased the Third Reich on the international stage. Propaganda minister Joseph Goebbels made effective use of film, mass rallies, the government controlled artistic expression, promoting specific art forms and banning or discouraging others. Beginning in the late 1930s, Nazi Germany made increasingly aggressive territorial demands and it seized Austria and Czechoslovakia in 1938 and 1939. Hitler made a pact with Joseph Stalin and invaded Poland in September 1939. In alliance with Italy and smaller Axis powers, Germany conquered most of Europe by 1940, reichskommissariats took control of conquered areas, and a German administration was established in what was left of Poland. Jews and others deemed undesirable were imprisoned, murdered in Nazi concentration camps and extermination camps, following the German invasion of the Soviet Union in 1941, the tide gradually turned against the Nazis, who suffered major military defeats in 1943

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Syrian Civil War
–
The Syrian Civil War is an armed conflict taking place in Syria. Syrian opposition groups formed the Free Syrian Army and seized control of the area surrounding Aleppo, over time, some factions of the Syrian opposition split from their original moderate position to pursue an Islamist vision for Syria, joining groups such as al-Nusra Front and ISIL. In 2015, the Yekîneyên Parastina Gel joined forces with Arab, Assyrian, Armenian, Russia and Hezbollah militarily engaged in support of the Syrian government, while beginning in 2014, a coalition of NATO countries began launching airstrikes against ISIL. International organizations have accused the Syrian government, ISIL, and some groups of severe human rights violations. The conflict has caused a major refugee crisis, over the course of the war a number of peace initiatives have been launched, including the March 2017 Geneva peace talks on Syria led by the United Nations, but fighting continues. Syria became an independent republic in 1946, although democratic rule ended with a coup in March 1949, a popular uprising against military rule in 1954 saw the army transfer power to civilians. From 1958 to 1961, a union with Egypt replaced Syrias parliamentary system with a highly centralized presidential government. The secular Baath Syrian Regional Branch government came to power through a successful coup détat in 1963, for the next several years Syria went through additional coups and changes in leadership. In March 1971, Hafez al-Assad, an Alawite, declared himself President, on 31 January 1973, Hafez al-Assad implemented a new constitution, which led to a national crisis. They labeled Assad the enemy of Allah and called for a jihad against his rule, the government survived a series of armed revolts by Sunni Islamists, mainly members of the Muslim Brotherhood, from 1976 until 1982. Upon Hafez al-Assads death in 2000, his son Bashar al-Assad was elected as President of Syria, Bashar al-Assad and his wife Asma, a Sunni Muslim born and educated in Britain, initially inspired hopes for democratic reforms. The Damascus Spring, a period of social and political debate, the Damascus Spring largely ended in August 2001 with the arrest and imprisonment of ten leading activists who had called for democratic elections and a campaign of civil disobedience. In the opinion of his critics, Bashar al-Assad had failed to deliver on promised reforms, Syrian Arabs, together with some 600,000 Palestinian Arabs, make up roughly 74 percent of the population. Syria Muslims are 74 percent Sunnis, and 13 percent Shias,3 percent were Druze, not all of the Sunnis are Arabs. Bashar is married to a Sunni, with whom he has several children and he is affiliated with the sect that his parents belong to, the minority Alawite sect which comprises an estimated 8-12 percent of the total population. Assyrians, an indigenous Eastern Aramaic-speaking Christian Semitic people, numbering approximately 500,000, are mainly in northeast Syria. A larger population lives over the border in northern Iraq, other ethnic groups include Armenians, Circassians, Turkmens, Greeks, Mhallami, Kawliya, Yezidi, Shabaks, and Mandeans. Socioeconomic inequality increased significantly after free market policies were initiated by Hafez al-Assad in his later years, the country also faced particularly high youth unemployment rates

Rheinmetall Defence has three divisions, Weapon and Munition, Electronic Solutions, and Vehicle Systems and its subsidiaries and affiliates are embedded in these three divisions. Though based in Germany, Rheinmetall Defence now has production plants, at the start of the twentieth century Dreysesche Gewehrfabrik, Munitions- und Waffenfabrik was added to Rheinmetall. After World War I, as a result of the treaty limitations imposed upon Germany, in 1935, the Reich took majority shareholding. The railway locomotive manufacturer August Borsig GmbH was taken over in 1933 and this led to the merger in 1936 giving Rheinmetall-Borsig AG. The Reichswehr placed a contract with Rheinmetall for a tank design leading to the Neubaufahrzeug, the company went on to produce guns for tanks used by the Wehrmacht and anti-tank guns. Production facilities were damaged by Allied bombing during World War II leading to relocation in eastern Germany, in the immediate post-war military production was banned and it was not until 1956 that arms production started again.

Krupp
–
The Krupp family, a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments. The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century and it was important to weapons development and production in both world wars. One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany. From the Thirty Years War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, the dynasty began in 1587 when a trader named Arndt Krupp moved to Essen and joined the merchants guild. He then began buying vacated real estate from families who fled the city due to the Black Death, over the next three centuries his descendants began producing small guns during the Thirty Years War and over time gradually acquired fulling mills, coal mines, and an iron forge. During the Napoleonic Wars, Friedrich Krupp founded the Gusstahlfabrik and began producing smelted steel in 1816, the foundations were laid for the steel Empire that would come to dominate the world for nearly a century under his son Alfred. Krupp became the manufacturer for the Kingdom of Prussia in 1859. Krupp was also a company that paved the way for workers rights. Widows and orphans were guaranteed pay if their husbands and/or fathers were killed, the company also produced the steel that built the railroads of America, capped the Chrysler Building in 1929, and was the first to travel to the bottom of the Mariana Trench. During the Third Reich, Krupp supported Adolf Hitler and the use of forced labour, after the war Krupp was rebuilt from scratch and again became one of the wealthiest companies in Europe. However a recession in 1967 caused the company severe profit loss, in 1999 the Krupp firm merged with Thyssen AG to form ThyssenKrupp AG, a large industrial conglomerate. Friedrich Krupp launched the familys metal-based activities, building a steel foundry in Essen in 1810. His son Alfred, known as the Cannon King or as Alfred the Great, invested heavily in new technology to become a significant manufacturer of steel rollers and he also invested in fluidized hotbed technologies and acquired many mines in Germany and France. Unusual for the era, he provided social services for his workers, including subsidized housing and health, the company began to make steel cannons in the 1840s—especially for the Russian, Turkish, and Prussian armies. When Alfred started with the firm, it had five employees, at his death twenty thousand people worked for Krupp—making it the worlds largest industrial company and the largest private company in the German empire. Krupps had a Great Krupp Building with an exhibition of guns at the Columbian Exposition in 1893, in the 20th century the company was headed by Gustav Krupp von Bohlen und Halbach, who assumed the surname of Krupp when he married the Krupp heiress, Bertha Krupp. After Adolf Hitler came to power in Germany in 1933, the Krupp works became the center for German rearmament. In 1943, by an order from Hitler, the company reverted to a sole-proprietorship, with Gustav

Reichsmark
–
The Reichsmark was subdivided into 100 Reichspfennig. The Mark is an ancient Germanic weight measure, traditionally a half pound, from 1871 to 1918 Germany was called the Kaiserreich, or the Deutsches Reich. Although Germany became a republic in 1919, the term Reich remained part of the official name. The Reichsmark was introduced in 1924 as a permanent replacement for the Papiermark and this was necessary due to the 1920s German inflation which had reached its peak in 1923. The exchange rate between the old Papiermark and the Reichsmark was 1 ℛℳ =1012 Papiermark, the Reichsmark was put on the gold standard at the rate previously used by the Goldmark, with the U. S. dollar worth 4.2 ℛℳ. As the market crash of 1929 expanded into the Great Depression and it retained a gold peg at that time. Hyper inflation ensued to the point it was cheaper to burn reichsmark paper notes than to buy fire wood, a number of companies were created with inadequate capital for their operations and authorized to issue bonds exchangeable at a 1,1 rate for Reichsmarks and sold at a discount. The Reichsbank rediscounted the bills of these companies creating a monetary expansion without formally renouncing the link to gold, Deutsche Gesellschaft für öffentliche Arbeiten AG, founded 1 August 1930, ended up issuing 1.26 billion Reichsmarks of Öffa bills to finance public construction. It formed the model for further fraudulent issues of bills. MEFO was a company that was formed with relatively small amounts of capital that was used to finance German rearmament off the books. It issued bills without backing by its own resources but which were guaranteed redeemable at 1,1 for Reichsmarks for five years by the government, the MEFO bills amounts were considered a state secret and were an important element in the impression that Hitlerian economics was a success. This company essentially created an amount of Reichsmarks off the books. With the unification of Germany and Austria in 1938, the Reichsmark replaced the Schilling in Austria. The rates were as follows, After the Second World War, the Reichsmark continued to circulate in Germany, in practice, massive inflation dating back to the latter stages of the war had rendered the Reichsmark nearly worthless. For all intents and purposes, it was supplanted by a barter economy, the Reichsmark was replaced in June 1948 by the Deutsche Mark in the Trizone and later in the same year by the East German Mark in East Germany. Tenenbaum of the US military government, and was executed abruptly on 21 June 1948, three days later, the new currency also replaced the Reichsmark in the three Western sectors of Berlin. In November 1945, the Reichsmark was superseded by the Allied Military Schilling in Austria, in 1947 a local currency was introduced in the Saar. In 1924, coins were introduced in denominations of 1,2,5,10, and 50 Reichspfennig, the 1 and 2 Reichspfennig were struck in bronze, and depicting a wheat sheaf

10.5 cm leFH 18M
–
The 10.5 cm leFH 18M was a German light howitzer used in the Second World War. The gun, less the carriage and shield, was used as the armament of the SdKfz 124 Wespe self-propelled artillery vehicle. The 10.5 cm leFH 18M superseded the 10.5 cm leFH18 as the standard German divisional field howitzer used during the Second World War. It was designed and developed by Rheinmetall after the war broke out in an effort to get more range from the basic leFH18 design, a muzzle brake was fitted and the recoil system adjusted to allow the use of a more powerful charge and new long-range shell. Generally it did not equip independent artillery battalions until after the Battle of Stalingrad in 1943,53 were also exported to Finland, where they were known as 105 H33. The 10.5 cm leFH 18M was also in service with the Syrian Army, the type has seen occasional service with rebel groups during the Syrian Civil War, in July 2013 and May 2015. Many were converted from the 10.5 cm leFH18, the former were only suitable for horse traction. Initially, it was fitted with a muzzle brake of relatively low efficiency. This was later improved by welding two protruding ears to the rear of the port, however this style of muzzle brake proved troublesome with the early designs of fin-stabilized and discarding-sabot shells and a new cage-type muzzle brake was designed and fitted. This fit in the cartridge case, but protruded about 50 millimetres past its mouth. Ballistically, the 10.5 cm leFH 18M and the leFH 18/40 are identical. 10.5 cm leFH16, a howitzer used by Germany in World War I and World War II10.5 cm leFH18, previous version of the leFH 18/M10.5 cm leFH 18/40.

10.5 cm leFH 18/40
–
The 10.5 cm leFH 18/40 was a German light howitzer used in World War II. The 10.5 cm leFH 18/40 supplemented the 10.5 cm leFH18 and it was designed in an effort to lighten the weight of the 105 mm artillery piece and to make it easier to produce. Generally it did not equip independent artillery battalions until after the Battle of Stalingrad in 1943, some were also exported to Finland, where they were known as 105 H 33-40. The Romanian Army acquired a number of leFH 18/40 in 1943, in March 1942 a requirement was issued for a lighter howitzer by the Wehrmacht that must also be ready as soon as possible and capable of rapid production. This requirement was met by mounting the barrel of the leFH 18M on the carriage for a 7.5 cm PaK40 antitank gun, the new carriage used torsion bars running the full length of the carriage to suspend the wheels. The original wheels of the PaK40 mounting were too small for use by the howitzer and were replaced by larger pressed-steel wheels with rubber tires. The new mounting increased the rate of fire as well as making the howitzer somewhat lighter, the leFH 18/40 shared the different muzzle brakes used by the leFH 18M. 10.5 cm leFH1810.5 cm leFH 18M Engelmann, Joachim and Scheibert, deutsche Artillerie 1934-1945, Eine Dokumentation in Text, Skizzen und Bildern, Ausrüstung, Gliederung, Ausbildung, Führung, Einsatz.

Gun barrel
–
A gun barrel is a part of firearms and artillery pieces. The hollow interior of the barrel is called the bore, a gun barrel must be able to hold in the expanding gas produced by the propellants to ensure that optimum muzzle velocity is attained by the projectile as it is being pushed out by the expanding gas. Modern small arms barrels are made of known and tested to withstand the pressures involved. Artillery pieces are made by various techniques providing reliably sufficient strength, early firearms were muzzle-loading, with powder, and then shot loaded from the muzzle, capable of only a low rate of fire. During the 19th century effective mechanical locks were invented that sealed a breech-loading weapon against the escape of propellant gases, the early Chinese, the inventors of gunpowder, used bamboo, a naturally tubular stalk, as the first barrels in gunpowder projectile weapons. Early European guns were made of iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings. The Chinese were the first to master cast-iron cannon barrels, early cannon barrels were very thick for their caliber.

Caliber (artillery)
–
In artillery, caliber or calibre is the internal diameter of a gun barrel, or by extension a relative measure of the length. Rifled barrels introduce ambiguity to measurement of caliber, a rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land, the depth of rifling grooves increases in larger calibers. United States Navy guns typically used rifling depth between one-half and one percent of caliber, projectile bourrelet diameter specification was 0.015 inches less than land to land diameter with a minus manufacturing tolerance so average clearance was about 0.012 inches. Driving band diameter was groove to groove diameter plus 0.02 inches, the length of the barrel is often quoted in calibers. For example, US Naval Rifles 3 in or larger, the effective length of the barrel is divided by the barrel diameter to give a dimensionless quantity.81 As an example, the main guns of the Iowa-class battleships can be referred to as 16/50 caliber. They are 16 inches in diameter and the barrel is 800 inches long, the bore to barrel length ratio is called caliber in naval gunnery,81 but is called length in army artillery. Before World War II, the US Navy used 5/51 caliber as surface-to-surface guns, by the end of World War II, the dual purpose 5/38 caliber was standard naval armament against surface and air targets. All three had a diameter of 5 inches. At sea, a weapon had to perform, without fail, there was no ready replacement, nor one that could be readily supplied. Over time, the terms of pound and bore became confused and blurred, eventually, when the technology existed, the bore came to be the standard measure. For naval rifles, the change was to actual bore. They then began to measure the length of the weapon in calibers. These were a measure of the bore of the barrel versus the rifled bore of the barrel. In other words, a 12/45 is 12×45= the length of the bore of that gun in inches. This explains the differences in both penetration and long range performance of naval rifles over the years. In addition to the improvements in overall performance, the increase in barrel length also allowed, in some circumstances. For example, the American 14/45, as introduced in the New York-class battleships, later improvements to the design, lengthening the rifle itself and also altering the breech, allowed a 1400 lb. projectile and, overall, a greater barrel life

Shell (projectile)
–
A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used, originally, it was called a bombshell, but shell has come to be unambiguous in a military context. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages, shells are usually large-calibre projectiles fired by artillery, combat vehicles, and warships. Shells usually have the shape of a cylinder topped by a nose for good aerodynamic performance, possibly with a tapering base. Solid cannonballs did not need a fuse, but hollow munitions filled with something such as gunpowder to fragment the ball, needed a fuse, percussion fuses with a spherical projectile presented a challenge because there was no way of ensuring that the impact mechanism hit the target. Therefore, shells needed a fuse that was ignited before or during firing. The earliest record of shells being used in combat was by the Republic of Venice at Jadra in 1376, shells with fuses were used at the 1421 siege of St Boniface in Corsica. These were two hollowed hemispheres of stone or bronze held together by an iron hoop, as described in their book, these hollow, gunpowder-packed shells were made of cast iron. At least since the 16th Century grenades made of ceramics or glass were in use in Central Europe, a hoard of several hundred ceramic greandes were discovered during building works in front of a bastion of the Bavarian City of Ingolstadt, Germany dated to the 17th Century. Lots of the grenades obtained their orignal blackpowder loads and igniters, most probably the grenades were intentionally dumped the moat of the bastion before the year 1723. Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire put down the barrel to light the fuse, other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite a powder fuse. Nevertheless, shells came into use in the 16th Century. By the 18th Century, it was known that the fuse towards the muzzle could be lit by the flash through the windage between the shell and the barrel, the use of exploding shells from field artillery became relatively commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder and they were usually made of cast iron, but bronze, lead, brass and even glass shell casings were experimented with. The word bomb encompassed them at the time, as heard in the lyrics of The Star-Spangled Banner, typically, the thickness of the metal body was about a sixth of their diameter and they were about two thirds the weight of solid shot of the same calibre. To ensure that shells were loaded with their fuses towards the muzzle, in 1819, a committee of British artillery officers recognised that they were essential stores and in 1830 Britain standardised sabot thickness as a half inch. The sabot was also intended to reduce jamming during loading, despite the use of exploding shell, the use of smoothbore cannons, firing spherical projectiles of shot, remained the dominant artillery method until the 1850s. By the late 18th century, artillery could use canister shot to defend itself from infantry or cavalry attack and this involved loading a tin or canvas container filled with small iron or lead balls instead of the usual cannonball

Explosive material
–
An explosive charge is a measured quantity of explosive material, which may be composed of a single ingredient or a combination of two or more. Materials that detonate are said to be high explosives and materials that deflagrate are said to be low explosives, Explosives may also be categorized by their sensitivity. Sensitive materials that can be initiated by a small amount of heat or pressure are primary explosives. A wide variety of chemicals can explode, a number are manufactured specifically for the purpose of being used as explosives. The remainder are too dangerous, sensitive, toxic, expensive, unstable, in contrast, some materials are merely combustible or flammable if they burn without exploding. The distinction, however, is not razor-sharp, though early thermal weapons, such as Greek fire, have existed since ancient times, the first widely used explosive in warfare and mining was black powder, invented in 9th century China. This material was sensitive to water, and it produced copious amounts of dark smoke, the first useful explosive stronger than black powder was nitroglycerin, developed in 1847. Since nitroglycerin is a liquid and highly unstable, it was replaced by nitrocellulose, TNT in 1863, smokeless powder, dynamite in 1867, World War I saw the adoption of TNT trinitrotoluene in artillery shells. World War II saw a use of new explosives. In turn, these have largely replaced by more powerful explosives such as C-4. However, C-4 and PETN react with metal and catch fire easily, yet unlike TNT, C-4 and PETN are waterproof, the largest commercial application of explosives is mining. In Materials Science and Engineering, explosives are used in cladding, a thin plate of some material is placed atop a thick layer of a different material, both layers typically of metal. Atop the thin layer is placed an explosive, at one end of the layer of explosive, the explosion is initiated. The two metallic layers are forced together at high speed and with great force, the explosion spreads from the initiation site throughout the explosive. Ideally, this produces a metallurgical bond between the two layers and it is possible that some fraction of the surface material from either layer eventually gets ejected when the end of material is reached. Hence, the mass of the now welded bilayer, may be less than the sum of the masses of the two initial layers, there are applications where a shock wave, and electrostatics, can result in high velocity projectiles. Thus, explosives are substances that contain an amount of energy stored in chemical bonds. Consequently, most commercial explosives are compounds containing -NO2, -ONO2 and -NHNO2 groups that

Caliber
–
In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the barrel, or the diameter of the projectile it fires, in hundredths or sometimes thousandths of an inch. For example, a 45 caliber firearm has a diameter of.45 of an inch. Barrel diameters can also be expressed using metric dimensions, as in 9mm pistol, when the barrel diameter is given in inches, the abbreviation cal can be used. Good performance requires a bullet to closely match the diameter of a barrel to ensure a good seal. While modern cartridges and cartridge firearms are referred to by the cartridge name. Firearm calibers outside the range of 17 to 50 exist, but are rarely encountered. Larger calibers, such as.577.585.600.700, the.950 JDJ is the only known cartridge beyond 79 caliber used in a rifle. Referring to artillery, caliber is used to describe the length as multiples of the bore diameter. A 5-inch 50 calibre gun has a diameter of 5 in. The main guns of the USS Missouri are 1650 caliber, makers of early cartridge arms had to invent methods of naming the cartridges, since no established convention existed then. One of the early established cartridge arms was the Spencer repeating rifle, later various derivatives were created using the same basic cartridge, but with smaller-diameter bullets, these were named by the cartridge diameter at the base and mouth. The original No.56 became the. 56-56, and the smaller versions. 56-52. 56-50, the. 56-52, the most common of the new calibers, used a 50-cal bullet. Optionally, the weight in grains was designated, e. g. 45-70-405. Variations on these methods persist today, with new cartridges such as the.204 Ruger, metric diameters for small arms refer to cartridge dimensions and are expressed with an × between the bore diameter and the length of the cartridge case, for example,7. 62×51 NATO. This indicates that the diameter is 7. 62mm, loaded in a case 51mm long. Similarly, the 6. 5×55 Swedish cartridge has a diameter of 6.5 mm. An exception to rule is the proprietary cartridge used by U. S. maker Lazzeroni. The following table lists commonly used calibers where both metric and imperial are used as equivalents

Breech-loading weapon
–
A breech-loading gun is a firearm in which the cartridge or shell is inserted or loaded into a chamber integral to the rear portion of a barrel. Modern mass production firearms are breech-loading, early firearms, on the other hand, were almost entirely muzzle-loading. In field artillery, breech loading allows the crew to reload the gun without exposing themselves to fire or repositioning the piece. The main challenge for developers of breech-loading firearms was sealing the breech and this was eventually solved for smaller firearms by the development of the self-contained metallic cartridge. For firearms too large to use cartridges, the problem was solved by the development of the interrupted screw, breech-loading swivel guns were invented in the 14th century. The breech-loading swivel gun had a rate of fire, and was especially effective in anti-personnel roles. Breech-loading firearms are known from the 16th century, Henry VIII possessed one, which he apparently used as a hunting gun to shoot birds. More breech-loading firearms were made in the early 18th century, one such gun known to have belonged to Philip V of Spain, and was manufactured circa 1715, probably in Madrid. It came with a ready-to load reusable cartridge, patrick Ferguson, a British Army officer, developed in 1772 the Ferguson rifle, a breech-loading flintlock firearm. Later on into the century there were attempts in Europe at an effective breech-loader. There were concentrated attempts at improved cartridges and methods of ignition, the cartridge was loaded through the breech and fired with a needle. The needle-activated central-fire breech-loading gun would become a feature of firearms thereafter. The corresponding firearm was also developed by Pauly, Pauly made an improved version, which was protected by a patent on 29 September 1812. In 1846 another Paris Frenchman, Benjamin Houllier, patented the first fully metallic cartridge containing powder in a metallic shell, Houllier commercialised his weapons in association with the gunsmiths Blanchard or Charles Robert. In English-speaking countries the Flobert cartridge corresponds to the.22 BB, the first centrefire cartridge was introduced in 1855 by Pottet, with both Berdan and Boxer priming. The Dreyse Zündnadelgewehr or Dreyse needle gun, was a single-shot breech-loading rifle using a rotating bolt to seal the breech and it was so called because of its. 5-inch needle-like firing pin, which passed through a paper cartridge case to impact a percussion cap at the bullet base. It began development in the 1830s under von Dreyse and eventually a version of it was adopted by Prussia in the late 1840s. The paper cartridge and the gun had numerous deficiencies, specifically, however, the rifle was used to great success in the Prussian army in the Austro-Prussian war of 1866

Rifled breech loader
–
The spin imparted by the guns rifling gives projectiles directional stability and increased range. Loading from the rear of the gun leaves the crew exposed to enemy fire, allows smaller gun emplacements or turrets. This was both a safety issue and one of gun performance - all the propellant gas was needed to accelerate the projectile along the barrel. The second problem was speed of operation - how to close the breech before firing, two solutions were developed more or less in parallel, the screw breech block and sliding wedge or sliding block. Hence, unlike with a rifle cartridge, the breech mechanism itself somehow needed to provide obturation. Hence if the block circumference was divided into two sets of threads and gaps, the only needed to be rotated ¼ turn to lock it instead of several turns. The tradeoff was that only ½ the blocks circumference was threaded, until the 19th century, only muzzle-loaders were used. In 1837 Martin von Wahrendorff patented a design for a breech-loader with a cylindrical breech plug secured by a horizontal wedge, independently, Giovanni Cavalli first proposed a breech-loader gun in 1832 to the Sardinian Army, and first tested such a gun in 1845. Advances in metallurgy in the industrial era allowed for the construction of rifled breech-loading guns that could fire at a greater muzzle velocity. Production started in 1855 at the Elswick Ordnance Company and the Royal Arsenal at Woolwich, a degree of obturation was achieved via a cup on the face of the block being forced into a recessed ring on the chamber face. Whatever obturation that was achieved relied on manual labour rather than the power of the guns firing, however, the British Army and Navy preferred to revert to muzzle-loaders until larger high-powered breech-loaders with secure obturation systems that were relatively simple to operate were developed. In the meantime the French persevered with trying to develop breechloaders which combined faster loading than muzzle-loaders, high power, safety, the Lahitolle 95 mm cannon of 1875 with an interrupted screw breech met the first three requirements to a great extent and partially solved the obturation problem. Finally the de Bange system introduced in 1877 solved the problem with an asbestos pad impregnated with grease which expanded and sealed the breech on firing. The de Bange system formed the system for all subsequent screw breeches to the present day. Britain adopted the de Bange breech when it returned to breechloaders in the early 1880s after some experiments with the inferior Armstrong cup obturation system. Loading required the 3 operations in reverse and this was hence termed a three motion block and was slow to operate. While working as a designer for Thorsten Nordenfelt in London. This allowed the block to be unscrewed and swung out in two motions - the two motion interrupted screw breech, bofors continued to use this in medium artillery into the 20th century

Recoil
–
Recoil is the backward movement of a gun when it is discharged. To apply this counter-recoiling force, modern mounted guns may employ recoil buffering comprising springs and hydraulic recoil mechanisms, early cannons used systems of ropes along with rolling or sliding friction to provide forces to slow the recoiling cannon to a stop. Recoil buffering allows the maximum counter-recoil force to be lowered so that strength limitations of the gun mount are not exceeded, however, the same pressures acting on the base of the projectile are acting on the rear face of the gun chamber, accelerating the gun rearward during firing. This results in the required counter-recoiling force being proportionally lower, modern cannons also employ muzzle brakes very effectively to redirect some of the propellant gasses rearward after projectile exit. This provides a force to the barrel, allowing the buffering system. The same physics affecting recoil in mounted guns and cannons applies to hand-held guns, hands, arms and shoulders have considerable strength and elasticity for this purpose, up to certain practical limits. For this reason, establishing recoil safety standards for small arms remains challenging, a change in momentum of a mass requires a force, according to Newtons first law, known as the law of inertia, inertia simply being another term for mass. That force, applied to a mass, creates an acceleration, according to Newtons second law, the law of momentum -- changing the velocity of the mass changes its momentum. It is important to understand at this point that velocity is not simply speed, velocity is the speed of a mass in a particular direction. In a very technical sense, speed is a scalar, a magnitude, in summation, the total momentum of the system equals zero, surprisingly just as it did before the trigger was pulled. There are two conservation laws at work when a gun is fired, conservation of momentum and conservation of energy, recoil is explained by the law of conservation of momentum, and so it is easier to discuss it separately from energy. The nature of the process is determined by the force of the expanding gases in the barrel upon the gun. It is also determined by the force applied to the gun. The recoil force only acts during the time that the ejecta are still in the barrel of the gun, except for the case of zero-recoil, the counter-recoil force is smaller than the recoil force but lasts for a longer time. Since the recoil force and the force are not matched. In the zero-recoil case, the two forces are matched and the gun will not move when fired. In most cases, a gun is very close to a free-recoil condition, an example of near zero-recoil would be a gun securely clamped to a massive or well-anchored table, or supported from behind by a massive wall. For example, placing the butt of a large caliber gun directly against a wall, the recoil of a firearm, whether large or small, is a result of the law of conservation of momentum

Gun carriage
–
A gun carriage is a frame and mount that supports the gun barrel of an artillery piece, allowing it to be manoeuvred and fired. The earliest guns were laid directly onto the ground, with earth being piled up under the end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century, from the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon. By this time, the trunnion had been developed, with the result that the barrel could be held in two recesses in the carriage and secured with an iron band. This simplified elevation, which was achieved by raising or lowering the breech of the gun by means of a wedge called a quoin or later by a steel screw. During this time, the design of gun carriages evolved only slowly, the trunnions of the gun barrel sat on the top of the cheeks, the rearward part of each cheek was stepped so that the breech could be lifted by iron levers called handspikes. Traversing the gun was achieved by levering the rear of the carriage sideways with handspikes and these were designed to allow guns to be deployed on the battlefield and were provided with a pair of large wheels similar to those used on carts or wagons. The cheeks of field carriages were much narrower than those on the naval carriage, when the gun needed to be moved any distance, the trail could be lifted onto a second separate axle called a limber, which could then be towed by a team of horses or oxen. Limbers had been invented in France in about 1550, in recent times, most heavy guns in military service, that were not themselves mounted into a vehicles, have been mounted either with a field carriage or a split trail carriage. The field carriage is simpler - having two legs extend backwards, joining at a tail, being a hardpoint to hook on to a prime mover or set of horses, the split trail carriage, however, is more complicated, but offers distinct advantages. It consists of two legs, able to be spread independently to the sides, or brought together to allow towing or movement, in both cases, the tail of the carriage often serves to balance the gun, and protect it from rolling to any large extent. The split trail, however, allows the gun not only to be fired near the horizontal, as the field carriage does and this is less important for heavier artillery, as the guns already involve a long time to prepare a firing position. While this still limits the ability to track, it allows the guns to fire in any direction with minimal preparation. Furthermore, it part of each of the benefits of the field carriage, being weight, space. The practice has its origins in war and appears in the century in the Queens regulations of the British Army. In the United Kingdom, the visual distinction usually referred to is that in a state funeral and this distinguishing feature is not invariable, however, as shown by the use of naval ratings rather than horses at the ceremonial funeral for Lord Mountbatten in 1979

Gun laying
–
Gun laying is the process of aiming an artillery piece, such as a gun, howitzer or mortar on land, or at sea, against surface or air targets. It may be laying for direct fire, where the gun is aimed similarly to a rifle, or indirect fire, the term includes automated aiming using, for example, radar-derived target data and computer-controlled guns. Gun laying means moving the axis of the bore of the barrel in two planes, horizontal and vertical. A gun is traversed – rotated in a horizontal plane – to align it with the target, Gun laying is a set of actions to align the axis of a gun barrel so that it points in the required direction. This alignment is in the horizontal and vertical planes, Gun laying may be for direct fire, where the layer sees the target, or indirect fire, where the target may not be visible from the gun. Gun laying has sometimes called training the gun. Laying in the vertical plane uses data derived from trials or empirical experience, for any given gun and projectile types, it reflects the distance to the target and the size of the propellant charge. It also incorporates any differences in height between gun and target, with indirect fire, it may allow for other variables as well. With indirect fire the horizontal angle is relative to something, typically the guns aiming point, depending on the gun mount, there is usually a choice of two trajectories. The dividing angle between the trajectories is about 45 degrees, it varies due to gun dependent factors. Below 45 degrees the trajectory is called low angle, above is high angle, the differences are that low angle fire has a shorter time of flight, a lower vertex and flatter angle of descent. All guns have carriages or mountings that support the barrel assembly, early guns could only be traversed by moving their entire carriage or mounting, and this lasted with heavy artillery into World War II. Mountings could be fitted into traversing turrets on ships, coast defences or tanks, from circa 1900 field artillery carriages provided traverse without moving the wheels and trail. The carriage, or mounting, also enabled the barrel to be set at the elevation angle. With some gun mounts it is possible to depress the gun, some guns require a near-horizontal elevation for loading. An essential capability for any elevation mechanism is to prevent the weight of the barrel forcing its heavier end downward and this is greatly helped by having trunnions at the centre of gravity, although a counterbalance mechanism can be used. It also means the elevation gear has to be enough to resist considerable downward pressure. However, mortars, where the forces were transferred directly into the ground

TNT
–
Trinitrotoluene, or more specifically 2,4, 6-trinitrotoluene, is a chemical compound with the formula C6H23CH3. This yellow-colored solid is used as a reagent in chemical synthesis. The explosive yield of TNT is considered to be the measure of bombs. In chemistry, TNT is used to charge transfer salts. TNT was first prepared in 1863 by German chemist Julius Wilbrand and its potential as an explosive was not appreciated for several years, mainly because it was so difficult to detonate and because it was less powerful than alternatives. Its explosive properties were first discovered by another German chemist, Carl Häussermann, the German armed forces adopted it as a filling for artillery shells in 1902. The British started replacing lyddite with TNT in 1907, TNT is still widely used by the United States military, as well as construction companies around the world. The majority of TNT currently used by the US military is manufactured by Radford Army Ammunition Plant near Radford, in industry, TNT is produced in a three-step process. First, toluene is nitrated with a mixture of sulfuric and nitric acid to produce mononitrotoluene, the MNT is separated and then renitrated to dinitrotoluene. In the final step, the DNT is nitrated to trinitrotoluene using a mixture of nitric acid. Nitric acid is consumed by the process, but the diluted sulfuric acid can be reconcentrated and reused. The rinse water from sulphitation is known as red water and is a significant pollutant, control of nitrogen oxides in feed nitric acid is very important because free nitrogen dioxide can result in oxidation of the methyl group of toluene. This reaction is exothermic and carries with it the risk of a runaway reaction leading to an explosion. In the laboratory,2,4, 6-trinitrotoluene is produced by a two-step process, a nitrating mixture of concentrated nitric and sulfuric acids is used to nitrate toluene to a mixture of mono- and di-nitrotoluene isomers, with careful cooling to maintain temperature. The nitrated toluenes are then separated, washed with dilute sodium bicarbonate to remove oxides of nitrogen, towards the end of the nitration, the mixture is heated on a steam bath. The trinitrotoluene is separated, washed with a solution of sodium sulfite. TNT is one of the most commonly used explosives for military, industrial, TNT has been used in conjunction with hydraulic fracturing, a process used to recover oil and gas from shale formations. The technique involves displacing and detonating nitroglycerin in hydraulically induced fractures followed by wellbore shots using pelletized TNT, TNT is valued partly because of its insensitivity to shock and friction, with reduced risk of accidental detonation compared to more sensitive explosives such as nitroglycerin

German language
–
German is a West Germanic language that is mainly spoken in Central Europe. It is the most widely spoken and official language in Germany, Austria, Switzerland, South Tyrol, the German-speaking Community of Belgium and it is also one of the three official languages of Luxembourg. Major languages which are most similar to German include other members of the West Germanic language branch, such as Afrikaans, Dutch, English, Luxembourgish and it is the second most widely spoken Germanic language, after English. One of the languages of the world, German is the first language of about 95 million people worldwide. The German speaking countries are ranked fifth in terms of publication of new books. German derives most of its vocabulary from the Germanic branch of the Indo-European language family, a portion of German words are derived from Latin and Greek, and fewer are borrowed from French and English. With slightly different standardized variants, German is a pluricentric language, like English, German is also notable for its broad spectrum of dialects, with many unique varieties existing in Europe and also other parts of the world. The history of the German language begins with the High German consonant shift during the migration period, when Martin Luther translated the Bible, he based his translation primarily on the standard bureaucratic language used in Saxony, also known as Meißner Deutsch. Copies of Luthers Bible featured a long list of glosses for each region that translated words which were unknown in the region into the regional dialect. Roman Catholics initially rejected Luthers translation, and tried to create their own Catholic standard of the German language – the difference in relation to Protestant German was minimal. It was not until the middle of the 18th century that a widely accepted standard was created, until about 1800, standard German was mainly a written language, in urban northern Germany, the local Low German dialects were spoken. Standard German, which was different, was often learned as a foreign language with uncertain pronunciation. Northern German pronunciation was considered the standard in prescriptive pronunciation guides though, however, German was the language of commerce and government in the Habsburg Empire, which encompassed a large area of Central and Eastern Europe. Until the mid-19th century, it was essentially the language of townspeople throughout most of the Empire and its use indicated that the speaker was a merchant or someone from an urban area, regardless of nationality. Some cities, such as Prague and Budapest, were gradually Germanized in the years after their incorporation into the Habsburg domain, others, such as Pozsony, were originally settled during the Habsburg period, and were primarily German at that time. Prague, Budapest and Bratislava as well as cities like Zagreb, the most comprehensive guide to the vocabulary of the German language is found within the Deutsches Wörterbuch. This dictionary was created by the Brothers Grimm and is composed of 16 parts which were issued between 1852 and 1860, in 1872, grammatical and orthographic rules first appeared in the Duden Handbook. In 1901, the 2nd Orthographical Conference ended with a standardization of the German language in its written form

Wehrmacht
–
The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the Heer, the Kriegsmarine and the Luftwaffe, after the Nazi seizure of power in 1933, one of Adolf Hitler’s most overt and audacious moves was to establish the Wehrmacht, a modern armed forces fully capable of offensive use. In December 1941, Hitler designated himself as commander-in-chief of the Wehrmacht, the Wehrmacht formed the heart of Germany’s politico-military power. In the early part of World War II, Hitlers generals employed the Wehrmacht through innovative combined arms tactics to devastating effect in what was called a Blitzkrieg, the Wehrmachts new military structure, unique combat techniques, newly developed weapons, and unprecedented speed and brutality crushed their opponents. Closely cooperating with the SS, the German armed forces committed war crimes and atrocities. By the time the war ended in Europe in May 1945, only a few of the Wehrmacht’s upper leadership were tried for war crimes, despite evidence suggesting that more were involved in illegal actions. The German term Wehrmacht generically describes any nations armed forces, for example, the Frankfurt Constitution of 1848 designated all German military forces as the German Wehrmacht, consisting of the Seemacht and the Landmacht. In 1919, the term Wehrmacht also appears in Article 47 of the Weimar Constitution, establishing that, from 1919, Germanys national defense force was known as the Reichswehr, a name that was dropped in favor of Wehrmacht on 21 May 1935. In January 1919, after World War I ended with the signing of the armistice of 11 November 1918, in March 1919, the national assembly passed a law founding a 420, 000-strong preliminary army, the Vorläufige Reichswehr. The terms of the Treaty of Versailles were announced in May, the army was limited to one hundred thousand men with an additional fifteen thousand in the navy. The fleet was to consist of at most six battleships, six cruisers, submarines, tanks and heavy artillery were forbidden and the air-force was dissolved. A new post-war military, the Reichswehr, was established on 23 March 1921, General conscription was abolished under another mandate of the Versailles treaty. The Reichswehr was limited to 115,000 men, and thus the armed forces, under the leadership of Hans von Seeckt, though Seeckt retired in 1926, the army that went to war in 1939 was largely his creation. Germany was forbidden to have an air-force by the Versailles treaty, nonetheless and these officers saw the role of an air-force as winning air-superiority, tactical and strategic bombing and providing ground support. That the Luftwaffe did not develop a strategic bombing force in the 1930s was not due to a lack of interest, but because of economic limitations. The leadership of the Navy led by Grand Admiral Erich Raeder, officers who believed in submarine warfare led by Admiral Karl Dönitz were in a minority before 1939. By 1922, Germany had begun covertly circumventing the conditions of the Versailles Treaty, a secret collaboration with the Soviet Union began after the treaty of Rapallo. Major-General Otto Hasse traveled to Moscow in 1923 to further negotiate the terms, Germany helped the Soviet Union with industrialization and Soviet officers were to be trained in Germany

Division (military)
–
A division is a large military unit or formation, usually consisting of between 10,000 and 20,000 soldiers. Infantry divisions during the World Wars ranged between 10,000 and 30,000 in nominal strength, in most armies, a division is composed of several regiments or brigades, in turn, several divisions typically make up a corps. In the West, the first general to think of organising an army into smaller units was Maurice de Saxe, Marshal General of France. He died at the age of 54, without having implemented his idea, victor-François de Broglie put the ideas into practice. He conducted successful practical experiments of the system in the Seven Years War. The first war in which the system was used systematically was the French Revolutionary War. It made the more flexible and easy to manoeuvre. Under Napoleon, the divisions were grouped together into corps, because of their increasing size, napoleons military success spread the divisional and corps system all over Europe, by the end of the Napoleonic Wars, all armies in Europe had adopted it. In modern times, most military forces have standardized their divisional structures, the peak use of the division as the primary combat unit occurred during World War II, when the belligerents deployed over a thousand divisions. With technological advances since then, the power of each division has increased. Divisions are often formed to organize units of a particular type together with support units to allow independent operations. In more recent times, divisions have mainly been organized as combined arms units with subordinate units representing various combat arms, in this case, the division often retains the name of a more specialized division, and may still be tasked with a primary role suited to that specialization. For the most part, large cavalry units did not remain after World War II, in general, two new types of cavalry were developed, air cavalry or airmobile, relying on helicopter mobility, and armored cavalry, based on an autonomous armored formation. The former was pioneered by the 11th Air Assault Division, formed on 1 February 1963 at Fort Benning, on 29 June 1965 the division was renamed as the 1st Cavalry Division, before its departure for the Vietnam War. After the end of the Vietnam War, the 1st Cavalry Division was reorganised and re-equipped with tanks, the development of the tank during World War I prompted some nations to experiment with forming them into division-size units. Many did this the way as they did cavalry divisions, by merely replacing cavalry with AFVs. This proved unwieldy in combat, as the units had many tanks, instead, a more balanced approach was taken by adjusting the number of tank, infantry, artillery, and support units. A panzer division was a division of the Wehrmacht and the Waffen-SS of Germany during World War II

10.5 cm leFH 16
–
The 10.5 cm leichte Feldhaubitze 16 was a field howitzer used by Germany in World War I and World War II. It was introduced in 1916 as a successor to 10.5 cm Feldhaubitze 98/09, featuring a longer barrel and it had the same carriage as the 7.7 cm FK16. The Treaty of Versailles limited the Reichswehr to only 84 light field howitzers, the leFH16 remained the standard German howitzer until 1937, when the 10.5 cm leFH18 began to replace them in the artillery battalions. Guns turned over to Belgium as reparations after World War I were taken into German Army service after the conquest of Belgium as the 10.5 cm leFH327, engelmann, J.

Wespe
–
Kfz.124 Wespe, also known as Leichte Feldhaubitze 18/2 auf Fahrgestell Panzerkampfwagen II, was a German self-propelled artillery vehicle developed and used during the Second World War. It was based on a modified Panzer II chassis, in 1940, during the Battle of France, it was apparent that the intermediate tank of the German forces, the Panzer II, was unsuitable as a main battle tank. Though mechanically sound, it was both under-gunned and under-armoured, the chassis, however, proved servicable for providing mobility to the 10.5 cm field howitzer. Existing chassis were converted to self-propelled artillery vehicles, just as had been done with the Marder II, the design for the Wespe was produced by Alkett, and was based on the Panzer II Ausf. Alkett had earlier worked with Alfred Becker to convert captured French armoured vehicles into self-propelled artillery carriers, amongst other modifications to the Panzer II, the engine was moved forward and the chassis was slightly lengthened to gain sufficient space for the rear-mounted 10.5 cm leFH18 howitzer. The superstructure was armored, with 10 mm armor plate and was open at the top. The vehicles were produced by FAMOs Ursus plant in Warsaw, the Wespe was in production from February 1943 until June 1944, when Soviet forces approached the frontier. By that time,676 had been produced, an additional 159 were modified to serve as mobile artillery ammunition carriers. The Wespe first saw combat in 1943 on the Eastern Front, the vehicles were allocated to the armored artillery battalions of Panzer divisions along with heavier Hummel self-propelled artillery. The Wespe brought greater mobility to the formations of the panzer divisions. The Wespe was very popular with its due to its reliability.

Hotchkiss H35
–
The Hotchkiss H35 or Char léger modèle 1935 H was a French cavalry tank developed prior to World War II. From 1938 an improved version was produced with an engine, the Char léger modèle 1935 H modifié39. For the remainder of the war Germany and its allies used captured Hotchkiss tanks in several modifications, in 1926 it had been decided to provide armour support to the regular infantry divisions by creating autonomous tank battalions equipped with a light and cheap infantry tank, a char daccompagnement. For this role at first the Char D1 was developed which type however proved to be particularly light nor cheap. On 30 June 1933 this proposal was approved by the Conseil Consultatif de lArmement, on 2 August 1933 the specifications were made known, a weight of six tons and 30 mm armour protection all around. Three prototypes were ordered from Hotchkiss, but the entire French industry was also invited to provide proposals for a nouveau char léger. This allowed the Renault company to beat Hotchkiss in delivering the first prototype and it was tested until 4 March 1935, when it was replaced by the second identical prototype to be tested until 6 May. Both had to be rejected because new specifications had been made on 21 June 1934 that increased the desired armour thickness to 40 mm, on 27 June 1935 the commission approved the type on the provision that the necessary changes would be made. On 19 August the third prototype was delivered, equipped with a cast APX turret and featuring a redesigned hull, it was tested until 20 September, on 6 November 1935 a first order was made for 200 vehicles. Though it should have been completed between July 1936 and July 1937, the first production vehicle was in fact delivered on 12 September 1936, a first additional orders had already been made of 92 on 7 September 1936, to be completed in November 1937. A third one of 108 vehicles followed on 23 January 1937 and these vehicles had the series number 40000 to 40400. By 1 January 1937132 hulls had been produced, none of these had at that date yet been fitted with a turret. The first series vehicle was extensively and intensively tested until 4 December 1936. The testing soon showed that its qualities in terrain were unacceptably poor. It was simply impossible to steer the vehicle on a somewhat bumpy surface. The Infantry therefore initially rejected any further procurement, eventually, in 1937, it decided to accept only the last hundred tanks to equip just two battalions with the type, the 13e and 38e Bataillon de Chars de Combat. For political reasons however stopping production of the tank was unacceptable, and so the first 300 vehicles of the production run were offered to the Cavalry, which was forced to accept them because it would not have been granted a budget for other tanks anyway. As the cavalry units would be making use of the road network and of mounted infantry

Char B1
–
The Char B1 was a French medium tank manufactured before World War II. Although a second uparmoured version, the Char B1 ter, was developed, after the defeat of France captured Char B1 would be used by Germany, with some rebuilt as flamethrowers or mechanised artillery. It had to be a Battle Tank that would be able to accomplish a breakthrough of the line by destroying fortifications, gun emplacements. In January 1921 a commission headed by General Edmond Buat initiated a project for such a vehicle, to limit costs, it had to be built like a self-propelled gun, with the main weapon in the hull. To minimise the vehicle size this gun should only be able to move up, two versions should be built, one a close support tank armed with a 75 mm howitzer, the other an antitank-vehicle with a 47 mm gun instead. French industry was interested in the project. In the past this had led to much non-constructive rivalry, Estienne, who in the war had personally witnessed the dismal effects of such a situation, was determined to avoid a repetition. To be allowed to join they had to agree beforehand to relinquish any patents to the Army, in exchange industry were promised very large orders of no less than a thousand vehicles. On these conditions four projects were started in 1921, two by a cooperation between Renault and Schneider, the SRA and the SRB, one by FAMH and the last by FCM, Renault and Schneider would each get to produce 250 units, FAMH and FCM each 125. A fifth producer, Delaunay-Belleville, whose project had been rejected beforehand, would be allowed to make 83 tanks, on 13 May 1924 the four prototypes were presented at the Atelier de Rueil, where they were compared, each having to drive over a twenty kilometre test course. Immediately it became evident that their development had been insufficient, most breaking down. Maintenance was difficult because the engines were inaccessible, all projects used a three-man crew but differed considerably in size, form and the solution chosen to laterally point the gun. The SRA was the heaviest vehicle at 19.5 metric tonnes and its length was 5.95 metres, its height 2. 26m and its width 2. 49m. It had a 75 mm howitzer in the side of the hull. It was steered by an epicyclical transmission combined with hydraulically reinforced brake disks, a Renault six-cylinder 180 hp engine allowed for a maximum speed of 17.5 km/h, a four hundred litre fuel tank for a range of 140 kilometres. The SRB, also using leaf springs, was a larger vehicle. It was nevertheless lighter at 18.5 tonnes, a result of having a smaller 47 mm gun—it thus was the antitank version, using the same engine, its speed was accordingly slightly higher at 18 km/h. More limited fuel reservoirs holding 370 litres decreased the range to 125 kilometres and it used an advanced hydraulic suspension system and the hydraulic Naeder-transmission from the Chaize company combined with a Fieux clutch and Schneider gear box

Lorraine 37L
–
A prototype was built in 1937 and production started in 1939. In this period also two armoured carriers and a tank destroyer project were based on its chassis. Mainly equipping the larger mechanised units of the French Infantry arm, after the defeat of France, clandestine manufacture was continued in Vichy France culminating in a small AFV production after the liberation and bringing the total production to about 630 in 1945. In 1934 the order was given to design a munition supply vehicle to increase the range of independent tank units. The same year the Renault 36R was selected for further development, early in 1937 the Lorraine company finished a prototype. It was a version of a proposed replacement type for the 1931 model Renault UE Chenillette tracked infantry supply tractor. The prototype was presented on 9 July and tested until 4 August. It was equipped with a 2371 cc Delahaye four cylinder 124 F engine, although the vehicle attained a maximum speed of 30 km/h, this dropped to an unacceptably low 22.8 km/h when an intended fuel trailer was attached. The commission approved the type during late 1937, being impressed by the rugged suspension system. It was decided in September 1939 to reserve the total capacity of the suspension elements for the larger tractor. The first vehicle was delivered by Lorraine on 11 January 1939,212 had been delivered on 1 September 1939. The ambitious plans made after the outbreak of war for the expansion of the number of armoured divisions meant that the Lorraine 37L orders had to be enlarged accordingly, the intended initial production rate was fifty per month, to be expanded to seventy. To assist in the manufacture a second hall was erected by Fouga at Béziers of which it was hoped that it could produce at first twenty. In reality this number was never attained, e. g. twenty were made in January,32 by both companies in May 1940, on 26 May 1940432 vehicles had been delivered to the army by Lorraine and Fouga out of 440 produced. Production continued after that date and a total of about 480 to 490 had been reached by 25 June 1940. Being derived from a project, the Lorraine 37 L is a rather small vehicle. Space had been found by lengthening the chassis to 4.22 metres, lacking a turret or superstructure its height is also not excessive at just 1.215 metres.24 metric tonnes empty, the trailer adding 1.2 tonnes. Six large road wheels in three bogie pairs gave a low pressure and good weight distribution

Reichswehr
–
The Reichswehr formed the military organisation of Germany from 1919 until 1935, when it was united with the new Wehrmacht. At the end of World War I, the forces of the German Empire had mostly split up, many of them joined the Freikorps, a collection of volunteer paramilitary units that were involved in suppressing the German Revolution and border clashes between 1918 and 1923. The Vorläufige Reichswehr was made up of 43 brigades, on 30 September 1919, the army was reorganised as the Übergangsheer, and the force size was reduced to 20 brigades. About 400,000 men served in the armed forces, in May 1920 it was downsized to 200,000 men and restructured again, forming three cavalry divisions and seven infantry divisions. On 1 October 1920 the brigades were replaced by regiments and the manpower was now only 100,000 men as stipulated by the Treaty of Versailles and this lasted until 1 January 1921, when the Reichswehr was officially established according to the limitations imposed by the Treaty of Versailles. The Reichswehr was an organisation composed of the following, The Reichsheer, an army consisting of, seven infantry divisions. General Command 1 at Berlin supervised 1st Division, 2nd Division, 3rd Division, general Command 2 at Kassel supervised 5,6,7 and 3rd Cavalry divisions. The Reichsmarine, a navy with a number of certain types of ships. The Reichswehr was limited to an army of 100,000 men. The establishment of a staff was prohibited. Heavy weapons such as artillery above the calibre of 105 mm, armoured vehicles, submarines and capital ships were forbidden, compliance with these restrictions was monitored until 1927 by the Military Inter-Allied Commission of Control. Despite the limitations on its size, their analysis of the loss of World War I, research and development, secret testing abroad and planning for better times went on. In addition, although forbidden to have a staff, the army continued to conduct the typical functions of a general staff under the disguised name of Truppenamt. During this time, many of the leaders of the Wehrmacht — such as Heinz Guderian — first formulated the ideas that they were to use so effectively a few years later. Reflecting this position as a “state within the state”, the Reichswehr created the Ministeramt or Office of the Ministerial Affairs in 1928 under Kurt von Schleicher to lobby the politicians. The biggest influence on the development of the Reichswehr was Hans von Seeckt, after the Kapp Putsch, Hans von Seeckt took over this post. After Seeckt was forced to resign in 1926, Wilhelm Heye took the post, Heye was in 1930 succeeded by Kurt Freiherr von Hammerstein-Equord, who submitted his resignation on December 27,1933. The reduction of the strength of the German army from 780,000 in 1913 to 100,000 enhanced the quality of the Reichsheer because only the best were permitted to join the army

Waffenamt
–
Waffenamt was the German Army Weapons Agency. It was the centre for research and development of Germany and also during the Third Reich for weapons, ammunition and army equipment to the German Reichswehr and it was founded 8 November 1919 as Reichwaffenamt, and 5 May 1922 the name was changed to Heereswaffenamt. The task of overseeing Germanys gigantic World War II rearmament process was given to the Heeresabnahmestelle, later, in the middle of 1944, approximately 8,000 of these Abnahme inspectors were freed for service at the front. The Heeres-Abnahmewesen was responsible for the testing and acceptance of all weapons, equipment, in preparation for their new duties they were given a four-week course at the Heereswaffenmeisterschule. The course ended with a test for Technical Inspector which raised the rank of each applicant to that of Oberleutnant.

Altona, Hamburg
–
Altona is the westernmost urban borough of the German city state of Hamburg, on the right bank of the Elbe river. From 1640 to 1864 Altona was under the administration of the Danish monarchy, Altona was an independent city until 1937. In 2006 the population was 243,972, founded in 1535 as a village of fishermen in then Holstein-Pinneberg. In 1640, Altona came under Danish rule as part of Holstein-Glückstadt, Altona was one of the Danish monarchys most important harbour towns. The railroad from Altona to Kiel, the Hamburg-Altona–Kiel railway, was opened in 1844, members did business both in Hamburg and in Altona itself. All that remains after the Nazi Holocaust during World War II are the Jewish cemeteries, but in the 17th, 18th and 19th centuries, the Holstein-Pinneberg and later Danish Holstein had lower taxes and placed fewer civil impositions on their Jewish community than did the government of Hamburg. Along with all of Schleswig-Holstein, Altona became part of the Kingdom of Prussia in 1867, in 1871 Altona and the nearby city Hamburg were hit by cholera, with a minimum of 16 casualties in Altona. During the Weimar era following World War I, the city of Altona was disturbed by major labor strikes, inflation in Germany was a major problem. In 1923 Max Brauer, the mayor of Altona, directed that city personnel be paid in part with gas meter tokens, as these coins did not lose value from inflation. The most notable event at this time is the Altona Bloody Sunday on July 17,1932 when several persons were shot by the force during a demonstration of Nazi groups. After police raids and a court, on August 1,1933 Bruno Tesch and others were found guilty. In the 1990s, the Federal Republic of Germany reversed the convictions of Tesch, the Greater Hamburg Act removed Altona from the Free State of Prussia in 1937 and merged it with the Free and Hanseatic City of Hamburg in 1938. On 1 February 2007 the Ortsämter in Hamburg were dissolved, in Altona the precincts of Blankenese, Lurup and Osdorf had existed and had local offices. The border of Altona to the south is the River Elbe, and across the river the state Lower Saxony, to the east is the borough Hamburg-Mitte and to the north is the borough Eimsbüttel. The western border is with the state of Schleswig-Holstein, according to the statistical office of Hamburg, the area of Altona is 77.5 km² or 29.9 sq mi in 2006. 16. 4% were children under the age of 18, and 18. 6% were 65 years of age or older,12,545 people were registered as unemployed. In 1999 48% of all households were made up of individuals, there were 37 elementary schools and 30 secondary schools in Altona and 635 physicians in private practice and 67 pharmacies. Simultaneously with elections to the parliament, the Bezirksversammlung is elected as representatives of the citizens

Magdeburg is the capital city and the second largest city of the state of Saxony-Anhalt, Germany. Magdeburg is situated on the Elbe River and was one of the most important medieval cities of Europe, Emperor Otto I, the first Holy Roman Emperor, founder of the archbishopric of Magdeburg, was buried in the towns cathedral after his death. Magdeburgs version of German town law, known as Magdeburg rights, spread throughout Central, the city is also well known for the 1631 Sack of Magdeburg, which hardened Protestant resistance during the Thirty Years War. Prior to it Magdeburg was one of the largest German cities, Magdeburg was destroyed twice in its history. Magdeburg is the site of two universities, the Otto-von-Guericke University and the Magdeburg-Stendal University of Applied Sciences, nowadays Magdeburg is a traffic junction as well as an industrial and trading centre. In 2005 Magdeburg celebrated its 1200th anniversary, in June 2013 Magdeburg was hit by record breaking flooding. Founded by Charlemagne in 805 as Magadoburg, the town was fortified in 919 by King Henry I the Fowler against the Magyars and Slavs. Edith loved the town and often lived there, at her death she was buried in the crypt of the Benedictine abbey of Saint Maurice, in 937, Magdeburg was the seat of a royal assembly. Otto I repeatedly visited Magdeburg and was buried in the cathedral. He granted the abbey the right to income from various tithes, the Archbishopric of Magdeburg was founded in 968 at the synod of Ravenna, Adalbert of Magdeburg was consecrated as its first archbishop. The archbishopric under Adalbert included the bishoprics of Havelberg, Brandenburg, Merseburg, Meissen, the archbishops played a prominent role in the German colonisation of the Slavic lands east of the Elbe river. In 1035 Magdeburg received a patent giving the city the right to hold exhibitions and conventions. These laws were adopted and modified throughout Central and Eastern Europe, visitors from many countries began to trade with Magdeburg. In the 13th century, Magdeburg became a member of the Hanseatic League, with more than 20,000 inhabitants Magdeburg was one of the largest cities in the Holy Roman Empire. The town had a maritime commerce on the west, with the countries of the North Sea. The citizens constantly struggled against the archbishop, becoming independent from him by the end of the 15th century. In about Easter 1497, the then twelve-year-old Martin Luther attended school in Magdeburg, in 1524, he was called to Magdeburg, where he preached and caused the citys defection from Catholicism. The Protestant Reformation had quickly found adherents in the city, where Luther had been a schoolboy, Emperor Charles V repeatedly outlawed the unruly town, which had joined the Alliance of Torgau and the Schmalkaldic League

Dortmund is an independent city in North Rhine-Westphalia, Germany. It is in the part of the state and is considered to be the administrative. Its population of 581,612 makes it the 8th largest city in Germany, moreover, Dortmund is the largest city by area and population in the Ruhr Area, an urban area with some 5.1 million inhabitants which is the largest urban agglomeration in Germany. Founded around 882, Dortmund became an Imperial Free City, throughout the 13th to 14th centuries, it was the chief city of the Rhine, Westphalia, the Netherlands Circle of the Hanseatic League. After the Thirty Years War the city was destroyed and decreased in significance until the onset of industrialization, the city then became one of Germanys most important coal, steel and beer centres. Thereby Dortmund was one of the most heavily bombed cities in Germany during World War II, the devastating bombing raids of the 12th March 1945 destroyed 98% of buildings in the inner city center. This bombing raids with more than 1,110 aircraft was a record to a target in World war II. The region has adapted since the collapse of its century long steel and coal industries and shifted to high technology biomedical technology, micro systems technology and also services. In 2009, Dortmund was classified as a Node city in the Innovation Cities Index published by 2thinknow and is the most sustainable city in Germany, the city is known as Westphalias green metropolis. Nearly half the territory consists of waterways, woodland, agriculture. This stands in a stark contrast with nearly a years of extensive coal mining. Dortmund is home to Ballspielverein Borussia 09 e. V, Dortmund, commonly known as Borussia Dortmund, a successful club in German football. The first time Dortmund was mentioned in documents was around 882. as Throtmanni. After it was destroyed by a fire, the Holy Roman Emperor Frederick I had the town rebuilt in 1152 and it became an Imperial Free City. Throughout the 13th to 14th centuries, it was the city of the Rhine, Westphalia. After 1320, the city appeared in writing as Dorpmunde, in the years leading up to 1344, the English King even borrowed money from well-heeled Dortmund merchant families Berswordt and Klepping, offering the regal crown as security. In 1388, Count von Mark joined forces with Archbishop of Cologne, following a major siege lasting 18 months, peace negotiations took place and Dortmund emerged victorious. After Cologne was excluded after the Anglo-Hanseatic War, Dortmund was made capital of the Rhine-Westphalian, the 1661 earthquake made the Reinoldikirche collapse

Gun shield
–
A gun shield is a flat piece of armor designed to be mounted on a crew-served weapon such as a machine gun or artillery piece, or, more rarely, to be used with an assault rifle. Some mounted machine guns and artillery pieces are equipped with armor plates to protect the gunners from sniper fire. Salvaged metal plates can sometimes service as improvised gun shields, in the Vietnam War crews of armored fighting vehicles, Gun shields fell out of widespread use after the Vietnam war, but they have seen a resurgence in popularity during the 1990s. Israeli military analysts began urging the use of gun shields, pointing to the risk to soldiers exposed to fire from automatic weapons. In particular, it was noted that many casualties were hit in areas not protected by body armor or a helmet, the U. S. began using gun shields during the 2000s-era wars in Iraq and Afghanistan.

SdKfz 6
–
The SdKfz 6 was a half-track military vehicle used by the German Wehrmacht during the Second World War. It was designed to be used as the towing vehicle for the 10.5 cm leFH18 howitzer. Development of a new artillery tractor began in 1934 at Büssing-NAG. The vehicle, produced in around 750 units until 1942, could carry up to 11 men in three rows, covered by a canvas structure. Along as a tractor for the 10.5 leFH18 howitzer, production was carried out by both Büssing-NAG and Daimler-Benz. The engine had a power from 90–100 hp, depending from the production version, SdKfz 6 was used by the various German military forces for the entire World War II. SdKfz 6/1, Standard half-tracked vehicle, used for towing artillery pieces. 37 mm FlaK36 auf Fahrgestell Zugkraftwagen 5t, SdKfz 6 fitted with a 3.7 cm FlaK36 gun,7.62 cm FK36 auf Panzerjäger Selbstfahrlafette Zugkraftwagen 5t.

Sd.Kfz. 11
–
11 was a German half-track that saw very widespread use in World War II. Its main role was as a prime mover for medium towed guns ranging from the 3.7 cm FlaK43 anti-aircraft gun up to the 10.5 cm leFH18 field howitzer and it could carry eight troops in addition to towing a gun or trailer. Borgward was chosen to develop the second smallest of the German half-tracks, however development was taken over in 1938 by Hanomag who designed the main production version, H kl 6. The chassis formed the basis for the Sd. Kfz, approximately 9,000 were produced between 1938 and 1945, making it one of the more numerous German tactical vehicles of the war. It participated in the Invasion of Poland, the Battle of France,11 used a conventional ladder frame. Power was provided by a front-mounted Maybach six-cylinder, water-cooled,4.17 litres HL42 TRKM gasoline engine of 100 horsepower and it had a Hanomag U50 transmission with four forward and one reverse gears. Maximum speed was 52.5 km/h and it could ford water.5 metres deep, both tracks and wheels were powered as well as used for steering. The steering system was set up so that turns used only the wheels. The drive sprocket had rollers rather than the more common teeth, the rear suspension consisted of six double roadwheels, overlapping and interleaved in the Schachtellaufwerk system, mounted on swing arms sprung by torsion bars. An idler wheel, mounted at the rear of the vehicle, was used to control track tension, the front wheels, carried on the rigid front axle, had transversely mounted leaf springs and shock absorbers, the only ones on the vehicle, to dampen impacts. Two different upper bodies were built over the run of the Sd. Kfz. The artillery body had an ammunition compartment separating the drivers compartment from the crew compartment, the ammunition compartment had doors that opened on each side of the vehicle and could be configured for different sizes of ammunition. Bench seats on the sides of the vehicle, with under-seat storage, the crew entered from the rear of the vehicle. The windshield could fold forward and was also removable, a convertible canvas top was mounted above the ammunition compartment. It fastened to the windshield and to the rear of the compartment when erected. Side pieces could be mounted to protect the crew from the weather, the engineer body had three bench seats for the crew and a convertible canvas top was mounted at the upper part of the rear body. It fastened to the windshield when erected, side pieces could be mounted to protect the crew from the weather. There was a compartment at the rear of the vehicle

Artillery tractor
–
An artillery tractor, also referred to as a gun tractor, is a specialized heavy-duty form of tractor unit used to tow artillery pieces of varying weights and calibres. It may be wheeled, tracked, or half-tracked, there are two main types of artillery tractors, depending on the type of traction, wheeled and tracked. Wheeled tractors are usually variations of lorries adapted for military service, tracked tractors run on continuous track, in some cases are built on a modified tank chassis with the superstructure replaced with a compartment for the gun crew or ammunition. In addition, half-track tractors were used in the period and in World War II. This type of tractor was discontinued in the postwar. The first artillery tractors were designed prior to the outbreak of World War I, such vehicles allowed the tactical use of heavier guns to supplement the light horse drawn field guns. Horseless artillery available prior to World War I weighed 8 tons, had 70 horsepower, for example, in the British Army it allowed the heavy guns of the Royal Garrison Artillery to be used flexibly on the battlefield. In World War II the draft horse was still the most common source of power in many armies. Most nations were economically and industrially unable to fully motorise their forces, one compromise was to produce general purpose vehicles which could be used in the troop transport, logistics and prime mover roles, with heavy artillery tractors to move the heaviest guns. The British Army had fully mechanized prior to war, german forces used half-tracks as artillery tractors, such as the Sd. Kfz. Half-tracked tractors were not commonly used in this role in other nations, compared to wheeled vehicles they had better off-road capabilities, but were slower on roads and were more prone to breakdowns. However, for Germany horses remained the most common way of towing artillery throughout the war, traditional towed artillery can still be found in units where complexity and weight are liabilities, e. g. airmobile, amphibious and other light units. In such units, where transport is usually limited, any available transport can double as artillery tractors in order to reposition guns when needed. For example, engineer vehicles of a different primary purpose such as the U. S, marines Light Capacity Rough Terrain Forklift, a versatile telehandler forklift capable of towing gear from either end.

Battle of Stalingrad
–
Marked by fierce close quarters combat and direct assaults on civilians by air raids, it is often regarded as one of the single largest and bloodiest battles in the history of warfare. German forces never regained the initiative in the East and withdrew a vast military force from the West to replace their losses, the German offensive to capture Stalingrad began in August 1942, using the German 6th Army and elements of the 4th Panzer Army. The attack was supported by intensive Luftwaffe bombing that reduced much of the city to rubble, the fighting degenerated into house-to-house fighting, and both sides poured reinforcements into the city. By mid-November 1942, the Germans had pushed the Soviet defenders back at great cost into narrow zones along the west bank of the Volga River. On 19 November 1942, the Red Army launched Operation Uranus, the Axis forces on the flanks were overrun and the 6th Army was cut off and surrounded in the Stalingrad area. Adolf Hitler ordered that the stay in Stalingrad and make no attempt to break out, instead, attempts were made to supply the army by air. Heavy fighting continued for two months. By the beginning of February 1943, the Axis forces in Stalingrad had exhausted their ammunition, the remaining units of the 6th Army surrendered. The battle lasted five months, one week, and three days, elsewhere, the war had been progressing well, the U-boat offensive in the Atlantic had been very successful and Rommel had just captured Tobruk. In the east, they had stabilized their front in a running from Leningrad in the north to Rostov in the south. There were a number of salients, but these were not particularly threatening, neither Army Group North nor Army Group South had been particularly hard pressed over the winter. Stalin was expecting the main thrust of the German summer attacks to be directed against Moscow again, with the initial operations being very successful, the Germans decided that their summer campaign in 1942 would be directed at the southern parts of the Soviet Union. The initial objectives in the region around Stalingrad were the destruction of the capacity of the city. The river was a key route from the Caucasus and the Caspian Sea to central Russia and its capture would disrupt commercial river traffic. The Germans cut the pipeline from the oilfields when they captured Rostov on 23 July, the capture of Stalingrad would make the delivery of Lend Lease supplies via the Persian Corridor much more difficult. On 23 July 1942, Hitler personally rewrote the operational objectives for the 1942 campaign, both sides began to attach propaganda value to the city based on it bearing the name of the leader of the Soviet Union. The expansion of objectives was a significant factor in Germanys failure at Stalingrad, caused by German overconfidence, the Soviets realized that they were under tremendous constraints of time and resources and ordered that anyone strong enough to hold a rifle be sent to fight. If I do not get the oil of Maikop and Grozny then I must finish this war, Army Group South was selected for a sprint forward through the southern Russian steppes into the Caucasus to capture the vital Soviet oil fields there

North African Campaign
–
The North African Campaign of the Second World War took place in North Africa from 10 June 1940 to 13 May 1943. It included campaigns fought in the Libyan and Egyptian deserts and in Morocco, the campaign was fought between the Allies and Axis powers, many of whom had colonial interests in Africa dating from the late 19th century. The Allied war effort was dominated by the British Commonwealth and exiles from German-occupied Europe, the United States entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942. Fighting in North Africa started with the Italian declaration of war on 10 June 1940, on 14 June, the British Armys 11th Hussars crossed the border from Egypt into Libya and captured the Italian Fort Capuzzo. Information gleaned via British Ultra code-breaking intelligence proved critical to Allied success in North Africa, victory for the Allies in this campaign immediately led to the Italian Campaign, which culminated in the downfall of the fascist government in Italy and the elimination of a German ally. On 10 May 1940, the Wehrmacht had started the Battle of France, one month later, it was plain to see that France would have to surrender within two weeks. On 10 June 1940, the Kingdom of Italy aligned itself with Nazi Germany and declared war upon France, British forces based in Egypt were ordered to undertake defensive measures, but to act as non-provocatively as possible. However, on 11 June they began a series of raids against Italian positions in Libya, following the defeat of France on 25 June, Italian forces in Tripolitania—facing French troops based in Tunisia—redeployed to Cyrenaica to reinforce the Italian Tenth Army. Italian dictator Benito Mussolini ordered the Tenth Army to invade Egypt by 8 August, two days later, no invasion having been launched, Mussolini ordered Marshal Graziani that, the moment German forces launched Operation Sea Lion, he was to attack. The battle plan was to advance along the road, while limited armoured forces operated on the desert flank. To counter the Italian advance, Wavell ordered his forces to harass the advancing Italians, falling back towards Mersa Matruh. Positioned on the flank was the 7th Armoured Division, which would strike the flank of the Italian force. By 16 September, the Italian force had advanced to Maktila, around 80 mi west of Mersa Matruh, in response to the dispersed Italian camps, the British planned a limited five-day attack, Operation Compass, to strike at these fortified camps one by one. The British Commonwealth force, totalling 36,000 men, attacked the forward elements of the 10-division-strong Italian army on 9 December, following their initial success, the forces of Operation Compass pursued the retreating Italian forces. In January, the port at Bardia was taken, soon followed by the seizure of the fortified port of Tobruk. Some 40,000 Italians were captured in and around the two ports, with the remainder of the Tenth Army retreating along the coast road back to El Agheila. Richard OConnor sent the 7th Armoured Division across the desert, with a reconnaissance group reaching Beda Fomm some ninety minutes before the Italians. Although desperate attempts were made to overcome the British force at the Battle of Beda Fomm, the Italians were unable to break through, and the remnants of the retreating army surrendered

Panzer division
–
The term panzer division as commonly used in English language refers almost exclusively to the armored division in the army branch of the Wehrmacht and of Nazi Germany during World War II. The panzer divisions were the key element of German success in the Blitzkrieg operations of the years of the war. Later the Waffen-SS formed panzer divisions, and even the Luftwaffe fielded a panzer division, the term Panzerdivision is still used in todays Army of the Bundeswehr. A panzer division was a combined formation, having both tanks and infantry as organic components, along with artillery, anti-aircraft, signals, etc. However, the proportions of the components of a panzer division changed over time, heinz Guderian first proposed the formation of panzer units larger than a regiment, but the inspector of motorized troops, Otto von Stuelpnagel, rejected the proposal. After his replacement by Oswald Lutz, Guderians mentor, the idea gained more support in the Wehrmacht, the first three panzer divisions were formed on 15 October 1935. Most other armies of the era organized their tanks into tank brigades that required additional organic, Panzer divisions had their own organic infantry and artillery support. This led to a change in doctrine, instead of the tanks supporting operations by other arms. Since the panzer divisions had the arms included, they could operate independently from other units. These first panzer divisions were composed of two regiments, one motorised infantry regiment of two battalions each, and supporting troops. Some of these divisions had quite a large proportion of Panzerkampfwagen I in them. After the invasion of Poland in 1939, the old divisions were partially reorganised, around this time, the newly organised divisions diverged in organisation, each on average with one tank regiment, one separate tank battalion, one or two infantry regiments. The number of tanks in the 1941-style divisions was relatively small, all other units in these formations were fully motorised to match the speed of the tanks. During the winter 1941/42, the divisions underwent another reorganisation, composing each tank regiment of one to three battalions, depending on location, throughout 1942, the reconnaissance battalions were merged into the motorcycle battalions. By the summer of 1943, the Luftwaffe and Waffen-SS also had panzer divisions, a renewed standardization of the tank regiments was attempted. Each was now supposed to consist of two battalions, one Panzer IV and one Panzer V, in reality, the organization continued to vary from division to division. The first infantry battalion of the first infantry regiment of each division was now supposed to be fully mechanised (mounted on armoured half-tracks. The first battalion of the regiment replaced its former light-towed howitzers with a mix of heavy
