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

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

Armoured warfare
–
Armoured warfare, mechanised warfare or tank warfare is the use of armoured fighting vehicles in modern warfare. It is a component of modern methods of war. The premise of armoured warfare rests on the ability of troops to penetrate defensive lines through use of manoeuvre by armoured units. Under these conditions, any sort of advance was very slow. Tanks were first developed in Britain and France in 1915, as a way of navigating the barbed wire, British Mark I tanks first went to action at the Somme, on 15 September 1916, but did not manage to break the deadlock of trench warfare. The first French employment on 16 April 1917, of the Schneider CA, was also a failure, in the Battle of Cambrai British tanks were more successful, and broke a German trenchline system, the Hindenburg Line. Despite the generally unpromising beginnings, the military and political leadership in both Britain and France during 1917 backed large investments into armoured vehicle production and this led to a sharp increase in the number of available tanks for 1918. The German Empire to the contrary, produced only a few tanks, twenty German A7V tanks were produced during the entire conflict, compared to over 4,400 French and over 2,500 British tanks of various kinds. Tactically, the deployment of armour during the war was typified by an emphasis on direct infantry support. The tanks main tasks were seen as crushing barbed wire and destroying machine-gun nests, theoretical debate largely focussed on the question whether a swarm of light tanks should be used for this or a limited number of potent heavy vehicles. Though in the Battle of Cambrai a large concentration of British heavy tanks effected a breakthrough, the manoeuvrability of the tank should at least in theory regain armies the ability to flank enemy lines. Following the First World War, the technical and doctrinal aspects of armoured warfare became more sophisticated and diverged into multiple schools of doctrinal thought, during the 1920s, only very few tanks were produced. There were however, important theoretical and technical developments, various British and French commanders who had contributed to the origin of the tank, such as Jean Baptiste Eugène Estienne, B. H. Liddell Hart and J. F. C. Fuller, theorised about a future use of independent armoured forces, containing a large concentration of tanks. Especially Liddell Hart wrote many books about the subject, partly propagating Fullers theories, such doctrines were faced with the reality that during the 1920s the armoured vehicles, as early road transport in general, were extremely unreliable, and could not be used in sustained operations. Mainstream thought on the subject was more conservative and tried to integrate armoured vehicles into the infantry and cavalry organisation. To save weight, such designs had thin armour plating and this inspired fitting small-calibre high-velocity guns in turrets, J. Collins, after Fuller refused the function. The unit carried out operations on Salisbury Plain and was observed by the major nations, the United States, Germany

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

Szczecin
–
Szczecin is the capital city of the West Pomeranian Voivodeship in Poland. Located near the Baltic Sea, it is a major seaport, as of June 2011, the population was 407,811. Szczecin is located on the Oder, south of the Szczecin Lagoon, the city is situated along the southwestern shore of Dąbie Lake, on both sides of the Oder and on several large islands between the western and eastern branches of the river. The citys recorded history began in the 8th century as a Slavic Pomeranian stronghold, in the 12th century, when Szczecin had become one of Pomeranias main urban centres, it lost its independence to Piast Poland, the Duchy of Saxony, the Holy Roman Empire and Denmark. At the same time, the House of Griffins established themselves as rulers, the population was Christianized. The native Slavic population was subjected to discrimination and Germanization in the following centuries, between 1237 and 1243, the town was rebuilt, granted extensive autonomy rights and eventually joined the Hanseatic League. After the Treaty of Stettin in 1630, the town came under the control of the Swedish Empire, in the late-19th century Stettin became an industrial town, vastly increasing in size and population, and served as a major port for Berlin. During the Nazi era, opposition groups and minorities were persecuted and treated as enemies, by the end of World War II Stettins status was in doubt, and the Soviet occupation authorities at first appointed officials from the citys almost entirely German pre-war population. In July 1945, however, Polish authorities were permitted to take power, Stettin was renamed Szczecin and became part of the newly established the Polish Peoples Republic, and from 1989 the Republic of Poland. From 1999 onwards, Szczecin has served as the site of the headquarters of NATOs Multinational Corps Northeast, the names Szczecin and Stettin are of Slavic origin, though the exact etymology is the subject of ongoing research. Other medieval names for the town are Burstaborg and Burstenburgh and these names, which literally mean brush burgh, are likely derived from the translation of the citys Slavic name. The recorded history of Szczecin began in the century, when West Slavs settled Pomerania. Since the 9th century, the stronghold was fortified and expanded toward the Oder bank, Mieszko I of Poland took control of Pomerania between 960 and 967, and the region with the city of Szczecin became part of Poland in 967. Subsequent Polish rulers, the Holy Roman Empire, and the Liutician federation all aimed to control the territory, after the decline of the neighbouring regional centre Wolin in the 12th century, the city became one of the more important and powerful seaports of the Baltic Sea. In a campaign in the winter of 1121–1122, Bolesław III Wrymouth, the inhabitants were Christianized by two missions of Bishop Otto of Bamberg in 1124 and 1128. At this time, the first Christian church of Saints Peter, Polish minted coins were commonly used in trade in this period. The population of the city at that time is estimated to be at around 5, Polish rule ended with Boleslaws death in 1138. There, a Polish contingent supplied by Mieszko III the Old joined the crusaders, however, the citizens had placed crosses around the fortifications, indicating they already had been Christianised

Operation Barbarossa
–
Operation Barbarossa was the code name for Nazi Germanys invasion of the Soviet Union during World War II, which was launched on Sunday 22 June 1941. In the two leading up to the invasion, the two countries signed political and economic pacts for strategic purposes. Nevertheless, the German High Command began planning an invasion of the Soviet Union in July 1940, over the course of the operation, about four million Axis personnel invaded the western Soviet Union along a 2, 900-kilometer front, the largest invasion force in the history of warfare. In addition to troops, the Wehrmacht employed some 600,000 motor vehicles, the offensive marked an escalation of the war, both geographically and in the formation of the Allied coalition. Despite their successes, the German offensive stalled in the Battle of Moscow and was pushed back by the Soviet winter counteroffensive. The Red Army repelled the Wehrmachts strongest blows and forced the unprepared Germans into a war of attrition, the Wehrmacht would never again mount a simultaneous offensive along the entire strategic Soviet–Axis front. The failure of the operation drove Hitler to demand further operations of limited scope inside the Soviet Union, such as Case Blue. The failure of Operation Barbarossa proved a point in the fortunes of the Third Reich. Most importantly, the operation opened up the Eastern Front, in more forces were committed than in any other theater of war in world history. The German armies captured 5,000,000 Soviet prisoners of war who were not granted protections stipulated in the Geneva Conventions, a majority of them never returned alive. The Nazis deliberately starved 3.1 million of the prisoners to death as part of a Hunger Plan that aimed to reduce the population of Eastern Europe, over a million Soviet Jews were murdered by Einsatzgruppen death squads and gassing as part of the Holocaust. On 10 February 1939, Hitler told his commanders that the next war would be purely a war of Weltanschauungen. Totally a peoples war, a racial war, on 23 November, once World War II had already started, Hitler declared that racial war has broken out and this war shall determine who shall govern Europe, and with it, the world. The racial policy of Nazi Germany viewed the Soviet Union as populated by non-Aryan Untermenschen, Hitler claimed in Mein Kampf that Germanys destiny was to turn to the East as it did six hundred years ago. Accordingly, it was stated Nazi policy to kill, deport, or enslave the majority of Russian and other Slavic populations and repopulate the land with Germanic peoples, under the Generalplan Ost. Likening the Soviets to the forces of Genghis Khan, Hitler told Croatian military leader Slavko Kvaternik that the Mongolian race threatened Europe. Following the invasion, Wehrmacht officers told their soldiers to target people who were described as Jewish Bolshevik subhumans, the Mongol hordes, the Asiatic flood, German army commanders cast the Jews as the major cause behind the partisan struggle. The main guideline policy for German troops was Where theres a partisan, theres a Jew, many German troops viewed the war in Nazi terms and regarded their Soviet enemies as sub-human

Battle of Kursk
–
The Battle of Kursk was a Second World War engagement between German and Soviet forces on the Eastern Front near Kursk in the Soviet Union during July and August 1943. The German offensive was code-named Operation Citadel and led to one of the largest armoured clashes in history, the German offensive was countered by two Soviet counter-offensives, Operation Polkovodets Rumyantsev and Operation Kutuzov. For the Germans, the battle was the strategic offensive that they were able to launch on the Eastern Front. Their extensive loss of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war. The Germans hoped to weaken the Soviet offensive potential for the summer of 1943 by cutting off a number of forces that they anticipated would be in the Kursk salient. The Kursk salient or bulge was 250 kilometres long north to south and 160 kilometres from east to west. The plan envisioned an envelopment by a pair of breaking through the northern and southern flanks of the salient. Adolf Hitler believed that a victory here would reassert German strength and improve his prestige with his allies and it was also hoped that large numbers of Soviet prisoners would be captured to be used as slave labour in the German armaments industry. The Soviet government had foreknowledge of the German intentions, provided in part by the British intelligence service, aware months in advance that the attack would fall on the neck of the Kursk salient, the Soviets built a defence in depth designed to wear down the German armoured spearhead. The Germans delayed the offensive while they tried to build up their forces and waited for new weapons, mainly the new Panther tank and this gave the Red Army time to construct a series of deep defensive belts. The defensive preparations included minefields, fortifications, artillery fire zones and anti-tank strong points, Soviet mobile formations were moved out of the salient and a large reserve force was formed for strategic counter-offensives. The Battle of Kursk was the first time in the Second World War that a German strategic offensive was halted before it could break through enemy defences, the maximum depth of the German advance was 8–12 kilometres in the north and 35 kilometres in the south. Though the Red Army had succeeded in winter offensives previously, their counter-offensives following the German attack at Kursk were their first successful strategic summer offensives of the war. As the Battle of Stalingrad slowly ground to its conclusion the Red Army moved to an offensive in the south. Army Group Center came under significant pressure as well, Kursk fell to the Soviets on 8 February 1943, and Rostov on 14 February. The Soviet Bryansk, Western, and newly created Central Fronts prepared for an offensive which envisioned the encirclement of Army Group Center between Bryansk and Smolensk, by February 1943 the southern sector of the German front was in strategic crisis. Since December 1942 Field Marshal Erich von Manstein had been strongly requesting unrestricted operational freedom to him to use his forces in a fluid manner. On 6 February 1943, Manstein met with Hitler at the headquarters in Rasternburg to discuss the proposals he had previously sent and he received an approval from Hitler for a counteroffensive against the Soviet forces advancing in the Donbass region

Minsk
–
Minsk (Belarusian, Мінск pronounced, is the capital and largest city of the Republic of Belarus, situated on the Svislach and Nyamiha rivers. It is the centre of the Commonwealth of Independent States. As the national capital, Minsk has an administrative status in Belarus and is the administrative centre of Minsk Region. In 2013, it had a population of 2,002,600, the earliest historical references to Minsk date to the 11th century, when it was noted as a provincial city within the principality of Polotsk. The settlement developed on the rivers, in 1242, Minsk became a part of the Grand Duchy of Lithuania. It received town privileges in 1499, from 1569, it was a capital of the Minsk Voivodeship in the Polish–Lithuanian Commonwealth. It was part of a region annexed by the Russian Empire in 1793, from 1919 to 1991, after the Russian Revolution, Minsk was the capital of the Byelorussian Soviet Socialist Republic within the Soviet Union. Minsk will host the 2019 European Games, Minsk is located on the southeastern slope of the Minsk Hills, a region of rolling hills running from the southwest to the northeast – that is, to Lukomskaye Lake in northwestern Belarus. The average altitude above sea level is 220 metres, the physical geography of Minsk was shaped over the two most recent ice ages. There are six smaller rivers within the city limits, all part of the Black Sea basin, Minsk is in the area of mixed forests typical of most of Belarus. Pinewood and mixed forests border the edge of the city, especially in the north, some of the forests were preserved as parks as the city grew. The city was built on the hills, which allowed for defensive fortifications. Minsk has a warm summer humid continental climate, owing to its location between the strong influence of the moist air of the Atlantic Ocean and the dry air of the Eurasian landmass. Its weather is unstable and tends to change often, the average January temperature is −4.5 °C, while the average July temperature is 18.5 °C. The lowest temperature was recorded on 17 January 1940, at −40 °C and the warmest on 29 July 1936 at 35 °C and this results in frequent fogs, common in the autumn and spring. Minsk receives annual precipitation of 690 millimetres, of one third falls during the cold period. Throughout the year, most winds are westerly and northwesterly, bringing cool, similar climatic regimes are found in Stockholm, Sweden and in Halifax, Canada. The ecological situation is monitored by Republican Centre of Radioactive and Environmental Control, during 2003–2008 the overall weight of contaminants increased from 186,000 to 247,400 tons

Smolensk
–
Smolensk is a city and the administrative center of Smolensk Oblast, Russia, located on the Dnieper River,360 kilometers west-southwest of Moscow. The walled city in the center of Smolensk was destroyed several times throughout its history because it was on the invasion routes of both Napoleon and Hitler. Today, Smolensk is noted for electronics, textiles, food processing, the name of the city is derived from the name of the Smolnya River. The origin of the name is less clear. One possibility is the old Slavic word смоль for black soil, an alternative origin could be the Russian word смола, which means resin, tar, or pitch. Pine trees grow in the area, and the city was once a center of resin processing, the Byzantine emperor Constantine VII recorded its name as Μιλινισκα. Within the city and its surroundings the river takes in small tributaries. In the valleys are stretched streets, high ridges, hills, Smolensk is situated on seven hills. The old part of the city occupies the high, rugged left bank of the Dnieper River, the area features undulating terrain, with a large number of tributaries, creeks and ravines. Smolensk is among the oldest Russian cities, the first recorded mention of the city was 863 AD, two years after the founding of Kievan Rus. According to Russian Primary Chronicle, Smolensk was located on the area settled by the West Slavic Radimichs tribe in 882 when Oleg of Novgorod took it in passing from Novgorod to Kiev, the first foreign writer to mention the city was the Byzantine Emperor Constantine Porphyrogenitus. In De Administrando Imperio he described Smolensk as a key station on the route from the Varangians to the Greeks. The Rus people sailed from the Baltics up the Western Dvina as far as they could then they portaged their boats to the upper Dnieper. It was in Smolensk that they supposedly mended any leaks and small holes that might have appeared in their boats from being dragged on the ground and they used tar to do that, the Principality of Smolensk was founded in 1054. Due to its position in Kievan Rus, the city developed rapidly. By the end of the 12th century, the princedom was one of the strongest in Eastern Europe, numerous churches were built in the city at that time, including the church of Sts. Peter and Paul and the church of St. John the Baptist, the most remarkable church in the city is called Svirskaya, it was admired by contemporaries as the most beautiful structure east of Kiev. Smolensk had its own veche since the beginning of its history

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

Panzer IV
–
The Panzerkampfwagen IV, commonly known as the Panzer IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd. Kfz, the Panzer IV was the most widely manufactured German tank of the Second World War, with some 8,500 built. The Panzer IV saw service in all combat theaters involving Germany and was the only German tank to remain in production throughout the war. Upgrades and design modifications, intended to counter new threats, extended its service life, the Panzer IV was the most widely exported tank in German service, with around 300 sold to Finland, Romania, Spain and Bulgaria. After the war, Syria procured Panzer IVs from France and Czechoslovakia, the Panzer IV was the brainchild of the German general and innovative armored warfare theorist Heinz Guderian. In concept, it was intended to be a tank for use against enemy anti-tank guns and fortifications. Ideally, each battalion in a panzer division was to have three medium companies of Panzer IIIs and one heavy company of Panzer IVs. On 11 January 1934, the German army wrote the specifications for a medium tractor, development was carried out under the name Begleitwagen, or BW, to disguise its actual purpose, given that Germany was still theoretically bound by the Treaty of Versailles ban on tanks. MAN, Krupp, and Rheinmetall-Borsig each developed prototypes, with Krupps being selected for further development, the chassis had originally been designed with a six-wheeled Schachtellaufwerk interleaved-roadwheel suspension, but the German Army amended this to a torsion bar system. Permitting greater vertical deflection of the roadwheels, this was intended to improve performance, in the turret, the tank commander sat beneath his roof hatch, while the gunner was situated to the left of the gun breech and the loader to the right. The turret was offset 66.5 mm to the left of the center line. Due to the layout, the right side of the tank contained the bulk of its stowage volume. Accepted into service as the Versuchskraftfahrzeug 622, production began in 1936 at Fried, Krupp Grusonwerk AG factory at Magdeburg. The first mass-produced version of the Panzer IV was the Ausführung A and it was powered by Maybachs HL 108TR, producing 250 PS, and used the SGR75 transmission with five forward gears and one reverse, achieving a maximum road speed of 31 kilometres per hour. As main armament, the vehicle mounted the short-barreled, howitzer-like 75 mm Kampfwagenkanone 37 L/24 tank gun, against armored targets, firing the Panzergranate at 430 metres per second the KwK37 could penetrate 43 millimetres, inclined at 30 degrees, at ranges of up to 700 metres. A7.92 mm MG34 machine gun was mounted coaxially with the weapon in the turret. The main weapon and coaxial machine gun were sighted with a Turmzielfernrohr 5b optic while the machine gun was sighted with a Kugelzielfernrohr 2 optic. A was protected by 14.5 mm of armor on the front plate of the chassis

Siege of Leningrad
–
The siege started on 8 September 1941, when the last road to the city was severed. Although the Soviets managed to open a land corridor to the city on 18 January 1943. It was one of the longest and most destructive sieges in history, Leningrads capture was one of three strategic goals in the German Operation Barbarossa and the main target of Army Group North. By 1939 the city was responsible for 11% of all Soviet industrial output and it has been reported Adolf Hitler was so confident of capturing Leningrad that he had invitations printed to the victory celebrations to be held in the citys Hotel Astoria. According to a sent to Army Group North on 29 September, After the defeat of Soviet Russia there can be no interest in the continued existence of this large urban center. Following the citys encirclement, requests for surrender negotiations shall be denied, since the problem of relocating and feeding the population cannot, in this war for our very existence, we can have no interest in maintaining even a part of this very large urban population. Hitlers ultimate plan was to raze Leningrad to the ground and give areas north of the River Neva to the Finns, Army Group North under Feldmarschall Wilhelm Ritter von Leeb advanced to Leningrad, its primary objective. Finnish military forces were north of Leningrad, while German forces occupied territories to the south, thus, it is argued that much of the Finns participation was merely defensive. The Germans planned on lack of food being their weapon against the citizens. On 27 June 1941, the Council of Deputies of the Leningrad administration organised First response groups of civilians, in the next days, Leningrads civilian population was informed of the danger and over a million citizens were mobilised for the construction of fortifications. Several lines of defences were built along the perimeter to repulse hostile forces approaching from north and south by means of civilian resistance. In the south, the line ran from the mouth of the Luga River to Chudovo, Gatchina, Uritsk, Pulkovo. Another line of defence passed through Peterhof to Gatchina, Pulkovo, Kolpino, in the north the defensive line against the Finns, the Karelian Fortified Region, had been maintained in Leningrads northern suburbs since the 1930s, and was now returned to service. Even the guns from the cruiser Aurora were moved inland to the Pulkovo Heights to the south of Leningrad, the 4th Panzer Group from East Prussia took Pskov following a swift advance and managed to reach Novgorod by 16 August. The Soviet defenders fought to the death, despite the German discovery of the Soviet defence plans on an officers corpse, after the capture of Novgorod, General Hoepners 4th Panzer Group continued its progress towards Leningrad. However, the 18th Army — despite some 350,000 men lagging behind — forced its way to Ostrov and Pskov after the Soviet troops of the Northwestern Front retreated towards Leningrad. On 10 July, both Ostrov and Pskov were captured and the 18th Army reached Narva and Kingisepp, from where advance toward Leningrad continued from the Luga River line. This had the effect of creating siege positions from the Gulf of Finland to Lake Ladoga, the Finnish Army was then expected to advance along the eastern shore of Lake Ladoga
