Tractor unit
–
A tractor unit is a characteristically heavy-duty towing engine that provides motive power for hauling a towed or trailered load. Tractor units typically have large displacement diesel engines for power, durability, and economy, several axles, the tractor-trailer combination distributes a load across multiple axles while being more maneuverable than an equivalently sized rigid truck. The most common trailer attachment system is a fifth wheel coupling, allowing rapid shift between trailers performing different functions, such as a bulk tipper and box trailer, trailers containing differing cargos can be rapidly swapped between tractors, eliminating downtime while a trailer is unloaded or loaded. Drawbar couplings are found, particularly in dedicated exceptionally heavy-duty ballast tractors. There have been three common cab configurations used in tractors, two are widely used. The conventional has an engine and hood over the front axle in front of the cab and this style is almost universal in North America. The cab over engine or cab forward has a flat nose cab with the sitting in front of the front axle. Widely used in the EU and Japan, this style has the advantages of good vision, maneuverability, in the North America this type of cab can be useful in straight trucks, but now has little advantage in tractors and is rarely used. A North American style cab over engine, now obsolete, had a flat nose cab located higher over the engine. This allowed a sleeper compartment in a tractor, and maximum wheelbase relative overall length. With the loosening of restrictions in 1982 this style had limited applications. In Australia both styles of cab over engine truck as well as conventionals are in common use, a tractor unit can have many axles depending on axle load legislation. The most common varieties are those of 4×2, 6×2 and 6×4 types, however, some manufacturers offer 6×6, 8×6, 8×8, 10×8, and 10×10 axle configurations. A 6×4 has three axles, normally an undriven front steer axle and the two axles driven. 6×4 units are common in long distance haulage in larger countries such as the United States. In Europe, the 4×2 and 6×2 variants are more commonplace, tractors with three axles or more can have more than one steering axle, which can also be driven. Most 6×2 units allow the rear axle to be raised when lightly loaded, or running without a trailer, to save tire wear, save toll road fees. The 8×8 units also have four axles, but with all of them driven, and 10×8 units have five axles with the rear four usually driven, all five axles of 10×10 units are driven

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

Vehicle armour
–
Military vehicles are commonly armoured to withstand the impact of shrapnel, bullets, missiles or shells, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft and ships, civilian vehicles may also be armoured. These vehicles include cars used by reporters, officials and others in conflict zones or where violent crime is common, armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the hijacking of the cargo. Armour may also be used in vehicles to protect from other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against impacts from micrometeoroids or fragments of space junk, the design and purpose of the vehicle determines the amount of armour plating carried, as the plating is often very heavy and excessive amounts of armour restrict mobility. In order to decrease this problem, some new materials and material compositions are being researched which include buckypaper, rolled homogeneous armour is strong, hard, and tough. Steel with these characteristics is produced by processing cast steel billets of appropriate size, rolling and forging irons out the grain structure in the steel, removing imperfections which would reduce the strength of the steel. Aluminium is used when weight is a necessity. It is most commonly used on APCs and armoured cars, wrought iron was used on ironclad warships. Early European iron armour consisted of 10 to 13 cm of wrought iron backed by up to one meter of solid wood, titanium is roughly the weight of aluminium, but as strong as iron. So despite being rather expensive, it finds an application in areas where weight is a concern, such as personal armour, because of its high density, depleted uranium can also be used in tank armour, sandwiched between sheets of steel armour plate. Plastic metal was a type of vehicle armour originally developed for merchant ships by the British Admiralty in 1940, the original composition was described as 50% clean granite of half-inch size, 43% of limestone mineral, and 7% of bitumen. It was typically applied in a two inches thick and backed by half an inch of steel. Plastic armour could be applied by pouring it into a cavity formed by the backing plate. Bulletproof glass is a term for glass that is particularly resistant to being penetrated when struck by bullets. The industry generally refers to it as bullet-resistant glass or transparent armour, bullet-resistant glass is usually constructed using a strong but transparent material such as polycarbonate thermoplastic or by using layers of laminated glass. The desired result is a material with the appearance and light-transmitting behaviour of standard glass, the polycarbonate layer, usually consisting of products such as Armormax, Makroclear, Cyrolon, Lexan or Tuffak, is often sandwiched between layers of regular glass. The use of plastic in the laminate provides impact-resistance, such as physical assault with a hammer, the plastic provides little in the way of bullet-resistance

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

Continuous track
–
Continuous track, also called tank tread or caterpillar track, is a system of vehicle propulsion in which a continuous band of treads or track plates is driven by two or more wheels. The prominent treads of the plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tracks provide good traction in soft surfaces but can damage paved surfaces, in modern times, continuous track propulsion systems can be traced back to a crude continuous track system designed in the 1770s by Richard Lovell Edgeworth. Polish mathematician and inventor Józef Maria Hoene-Wroński conceived of the idea in the 1830s, the British polymath Sir George Cayley patented a continuous track, which he called a universal railway. Although not a track in the form encountered today, a dreadnaught wheel or endless railway wheel was patented by the British Engineer James Boydell in 1846. In Boydells design, a series of feet are attached to the periphery of the wheel. A letter of recommendation was signed by Sir William Codrington, the General commanding the troops at Sebastapol, a number of manufacturers including Richard Bach, Richard Garrett & Sons, Charles Burrell & Sons and Clayton & Shuttleworth applied the Boydell patent under licence. The British military were interested in Boydells invention from an early date, one of the objectives was to transport Mallets Mortar, a giant 36 weapon which was under development but, by the end of the Crimean war, the mortar was not ready for service. In those tests, a Garrett engine was put through its paces on Plumstead Common, the Garrett engine featured in the Lord Mayors show in London, and in the following month that engine was shipped to Australia. Nicholas works in 1856, again, after the close of the Crimean war, between late 1856 and 1862 Burrell manufactured not less than a score of engines fitted with dreadnaught wheels. Steam tractors fitted with wheels had a number of shortcomings and. In August 1858, more than two years after the end of the Crimean War, John Fowler filed British Patent No.1948 on another form of Endless Railway, comprising only eight sections, the track sections are essentially longitudinal, as in Boydells initial design. Further to Fowlers patent of 1858, in 1877, a Russian, Fyodor Blinov and it lacked self-propulsion and was pulled by horses. Blinov received a patent for his wagon in 1878, from 1881 to 1888 he developed a steam-powered caterpillar-tractor. This self-propelled crawler was successfully tested and featured at an exhibition in 1896. Steam traction engines were used at the end of the 19th Century in the Boer Wars, but neither dreadnaught wheels nor continuous tracks were used, rather roll-out wooden plank roads were thrown under the wheels as required. A little-known American inventor, Henery T. Stith, developed a continuous track prototype which was, in forms, patented in 1873,1880. The last was for the application of the track to a prototype off-road bicycle built for his son, the 1900 prototype is retained by his surviving family

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

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

Rasputitsa
–
Rasputitsa is a season when travel on unpaved roads becomes difficult, owing to muddy conditions, either from autumnal rains or spring thaw. It also refers to the condition of the roads, during those seasons, the term is applied to muddy road conditions in Belarus, Russia and Ukraine, which are caused by the poor drainage of underlying clay-laden soils found in the region. Roads are subject to limitations and closures during the period in certain districts of the Russian Federation. The phenomenon was a hindrance in the part of the 20th Century in the Soviet Union. Rasputitsa seasons of Russia are well known as a defensive advantage in wartime. Common nicknames in such context are General Mud or Marshal Mud, during the French invasion of Russia in 1812, Napoleon found the mud to be a great hindrance. During the Second World War, the month-long muddy period slowed down the German advance during the Battle of Moscow, cold-weather warfare Russian Winter Mud season

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

Allies of World War II
–
The Allies of World War II, called the United Nations from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War. The Allies promoted the alliance as seeking to stop German, Japanese, at the start of the war on 1 September 1939, the Allies consisted of France, Poland and the United Kingdom, and dependent states, such as the British India. Within days they were joined by the independent Dominions of the British Commonwealth, Australia, Canada, New Zealand, Poland was a minor factor after its defeat in 1939, France was a minor factor after its defeat in 1940. China had already been into a war with Japan since the Marco Polo Bridge Incident of 1937. The alliance was formalised by the Declaration by United Nations, from 1 January 1942, however, the name United Nations was rarely used to describe the Allies during the war. The leaders of the Big Three – the UK, the Soviet Union, in 1945, the Allied nations became the basis of the United Nations. The origins of the Allied powers stem from the Allies of World War I, Germany resented signing Treaty of Versailles. The new Weimar republics legitimacy became shaken, by the early 1930s, the Nazi Party led by Adolf Hitler became the dominant revanchist movement in Germany and Hitler and the Nazis gained power in 1933. The Nazi regime demanded the cancellation of the Treaty of Versailles and made claims to German-populated Austria. The likelihood of war was high, and the question was whether it could be avoided through strategies such as appeasement, in Asia, when Japan seized Manchuria in 1931, the League of Nations condemned it for aggression against China. Japan responded by leaving the League of Nations in March 1933, after four quiet years, the Sino-Japanese War erupted in 1937 with Japanese forces invading China. The League of Nations condemned Japans actions and initiated sanctions on Japan, the United States, in particular, was angered at Japan and sought to support China. In March 1939, Germany took over Czechoslovakia, violating the Munich Agreement signed six months before, Britain and France decided that Hitler had no intention to uphold diplomatic agreements and responded by preparing for war. On 31 March 1939, Britain formed the Anglo-Polish military alliance in an effort to avert a German attack on the country, also, the French had a long-standing alliance with Poland since 1921. The Soviet Union sought an alliance with the powers. The agreement secretly divided the independent nations of eastern Europe between the two powers and assured adequate oil supplies for the German war machine, on 1 September 1939, Germany invaded Poland, two days later Britain and France declared war on Germany. Then, on 17 September 1939, the Soviet Union invaded Poland from the east, a Polish government-in-exile was set up and it continued to be one of the Allies, a model followed by other occupied countries. After a quiet winter, Germany in April 1940 invaded and quickly defeated Denmark, Norway, Belgium, Britain and its Empire stood alone against Hitler and Mussolini
