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

Finland
–
Finland, officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has borders with Sweden to the northwest, Norway to the north. Estonia is south of the country across the Gulf of Finland, Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finlands population is 5.5 million, and the majority of the population is concentrated in the southern region,88. 7% of the population is Finnish people who speak Finnish, a Uralic language unrelated to the Scandinavian languages, the second major group are the Finland-Swedes. In terms of area, it is the eighth largest country in Europe, Finland is a parliamentary republic with a central government based in the capital Helsinki, local governments in 311 municipalities, and an autonomous region, the Åland Islands. Over 1.4 million people live in the Greater Helsinki metropolitan area, from the late 12th century, Finland was an integral part of Sweden, a legacy reflected in the prevalence of the Swedish language and its official status. In the spirit of the notion of Adolf Ivar Arwidsson, we are not Swedes, we do not want to become Russians, let us therefore be Finns, nevertheless, in 1809, Finland was incorporated into the Russian Empire as the autonomous Grand Duchy of Finland. In 1906, Finland became the nation in the world to give the right to vote to all adult citizens. Following the 1917 Russian Revolution, Finland declared itself independent, in 1918, the fledgling state was divided by civil war, with the Bolshevik-leaning Reds supported by the equally new Soviet Russia, fighting the Whites, supported by the German Empire. After a brief attempt to establish a kingdom, the became a republic. During World War II, the Soviet Union sought repeatedly to occupy Finland, with Finland losing parts of Karelia, Salla and Kuusamo, Petsamo and some islands, Finland joined the United Nations in 1955 and established an official policy of neutrality. The Finno-Soviet Treaty of 1948 gave the Soviet Union some leverage in Finnish domestic politics during the Cold War era, Finland was a relative latecomer to industrialization, remaining a largely agrarian country until the 1950s. It rapidly developed an advanced economy while building an extensive Nordic-style welfare state, resulting in widespread prosperity, however, Finnish GDP growth has been negative in 2012–2014, with a preceding nadir of −8% in 2009. Finland is a top performer in numerous metrics of national performance, including education, economic competitiveness, civil liberties, quality of life, a large majority of Finns are members of the Evangelical Lutheran Church, though freedom of religion is guaranteed under the Finnish Constitution. The first known appearance of the name Finland is thought to be on three rune-stones. Two were found in the Swedish province of Uppland and have the inscription finlonti, the third was found in Gotland, in the Baltic Sea. It has the inscription finlandi and dates from the 13th century, the name can be assumed to be related to the tribe name Finns, which is mentioned first known time AD98. The name Suomi has uncertain origins, but a candidate for a source is the Proto-Baltic word *źemē, in addition to the close relatives of Finnish, this name is also used in the Baltic languages Latvian and Lithuanian

Romania
–
Romania is a sovereign state located in Southeastern Europe. It borders the Black Sea, Bulgaria, Ukraine, Hungary, Serbia and it has an area of 238,391 square kilometres and a temperate-continental climate. With over 19 million inhabitants, the country is the member state of the European Union. Its capital and largest city, Bucharest, is the sixth-largest city in the EU, the River Danube, Europes second-longest river, rises in Germany and flows in a general southeast direction for 2,857 km, coursing through ten countries before emptying into Romanias Danube Delta. The Carpathian Mountains, which cross Romania from the north to the southwest are marked by one of their tallest peaks, Moldoveanu, modern Romania was formed in 1859 through a personal union of the Danubian Principalities of Moldavia and Wallachia. The new state, officially named Romania since 1866, gained independence from the Ottoman Empire in 1877, at the end of World War I, Transylvania, Bukovina and Bessarabia united with the sovereign Kingdom of Romania. Romania lost several territories, of which Northern Transylvania was regained after the war, following the war, Romania became a socialist republic and member of the Warsaw Pact. After the 1989 Revolution, Romania began a transition back towards democracy and it has been a member of NATO since 2004, and part of the European Union since 2007. A strong majority of the population identify themselves as Eastern Orthodox Christians and are speakers of Romanian. The cultural history of Romania is often referred to when dealing with artists, musicians, inventors. For similar reasons, Romania has been the subject of notable tourist attractions, Romania derives from the Latin romanus, meaning citizen of Rome. The first known use of the appellation was attested in the 16th century by Italian humanists travelling in Transylvania, Moldavia, after the abolition of serfdom in 1746, the word rumân gradually fell out of use and the spelling stabilised to the form român. Tudor Vladimirescu, a leader of the early 19th century. The use of the name Romania to refer to the homeland of all Romanians—its modern-day meaning—was first documented in the early 19th century. The name has been officially in use since 11 December 1861, in English, the name of the country was formerly spelt Rumania or Roumania. Romania became the predominant spelling around 1975, Romania is also the official English-language spelling used by the Romanian government. The Neolithic-Age Cucuteni area in northeastern Romania was the region of the earliest European civilization. Evidence from this and other sites indicates that the Cucuteni-Trypillian culture extracted salt from salt-laden spring water through the process of briquetage

Czechoslovakia
–
From 1939 to 1945, following its forced division and partial incorporation into Nazi Germany, the state did not de facto exist but its government-in-exile continued to operate. From 1948 to 1990, Czechoslovakia was part of the Soviet bloc with a command economy and its economic status was formalized in membership of Comecon from 1949, and its defense status in the Warsaw Pact of May 1955. A period of liberalization in 1968, known as the Prague Spring, was forcibly ended when the Soviet Union, assisted by several other Warsaw Pact countries. In 1993, Czechoslovakia split into the two states of the Czech Republic and Slovakia. Form of state 1918–1938, A democratic republic, 1938–1939, After annexation of Sudetenland by Nazi Germany in 1938, the region gradually turned into a state with loosened connections among the Czech, Slovak, and Ruthenian parts. A large strip of southern Slovakia and Carpatho-Ukraine was annexed by Hungary, 1939–1945, The region was split into the Protectorate of Bohemia and Moravia and the Slovak Republic. A government-in-exile continued to exist in London, supported by the United Kingdom, United States and its Allies, after the German invasion of Russia, Czechoslovakia adhered to the Declaration by United Nations and was a founding member of the United Nations. 1946–1948, The country was governed by a government with communist ministers, including the prime minister. Carpathian Ruthenia was ceded to the Soviet Union, 1948–1989, The country became a socialist state under Soviet domination with a centrally planned economy. In 1960, the country became a socialist republic, the Czechoslovak Socialist Republic. It was a state of the Soviet Union. 1989–1990, The federal republic consisted of the Czech Socialist Republic, 1990–1992, Following the Velvet Revolution, the state was renamed the Czech and Slovak Federal Republic, consisting of the Czech Republic and the Slovak Republic. Neighbours Austria 1918–1938, 1945–1992 Germany Hungary Poland Romania 1918–1938 Soviet Union 1945–1991 Ukraine 1991–1992 Topography The country was of irregular terrain. The western area was part of the north-central European uplands, the eastern region was composed of the northern reaches of the Carpathian Mountains and lands of the Danube River basin. Climate The weather is mild winters and mild summers, influenced by the Atlantic Ocean from the west, Baltic Sea from the north, and Mediterranean Sea from the south. The area was long a part of the Austro Hungarian Empire until the Empire collapsed at the end of World War I, the new state was founded by Tomáš Garrigue Masaryk, who served as its first president from 14 November 1918 to 14 December 1935. He was succeeded by his ally, Edvard Beneš. The roots of Czech nationalism go back to the 19th century, nationalism became a mass movement in the last half of the 19th century

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.

Muzzle brake
–
A muzzle brake or recoil compensator is a device connected to the muzzle of a firearm or cannon that redirects propellant gases to counter recoil and unwanted rising of the barrel during rapid fire. They have been used in forms for rifles and pistols to help control recoil. They are used on pistols for practical pistol competitions, and are usually called compensators in this context, the interchangeable terms muzzle rise, muzzle flip, or muzzle climb refer to the tendency of a handheld firearms front end to rise after firing. Firearms with less height from the line to the barrel centerline tend to experience less muzzle rise. The muzzle rises primarily because, for most firearms, the centerline of the barrel is above the center of contact between the shooter and the grip and stock. The reactive forces from the bullet and propellant gases exiting the muzzle act directly down the centerline of the barrel. If that line of force is above the center of the points, this creates a moment or torque rotational force that makes the firearm rotate. The M1946 Sieg automatic rifle had a muzzle brake that made the rifle climb downward. Muzzle brakes are simple in concept, such as the one employed on the 90 mm M3 gun used on the M47 Patton tank and this consists of a small length of tubing mounted at right angles to the end of the barrel. Brakes most often utilize slots, vents, holes, baffles, the strategy of a muzzle brake is to redirect and control the burst of combustion gases that follows the departure of a projectile. All muzzle brake designs share a basic principle, they partially divert combustion gases at a sideways angle. The momentum of the diverted gases thus does not add to the recoil, the angle toward which the gases are directed will fundamentally affect how the brake behaves. If gases are directed upward, they exert a downward force. Construction of a brake or compensator can be as simple as a diagonal cut at the muzzle end of the barrel to direct some of the escaping gas upward. On the AKM assault rifle, the brake also angles slightly to the right to counteract the movement of the rifle under recoil. Another simple method is porting, where holes or slots are machined into the barrel near the muzzle to allow the gas to escape, more advanced designs use baffles and expansion chambers to slow escaping gases. This is the principle behind a linear compensator. Ports are often added to the chambers, producing the long

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

Glossary of British ordnance terms
–
This article explains terms used for the British Armed Forces ordnance and also ammunition. The terms may have different meanings in the military of other countries. Between decks, applies to a gun mounting in which part of the rotating mass is below the deck. This allows for a profile of turret, meaning that turrets need not be superfiring The term BL, in its general sense, stood for breech loading. The shell was loaded via the breech followed by the propellant charge, sealing the chamber to prevent escape of the propellant gases. The term BL was first used to refer to the Armstrong breechloaders, following the discontinuation of Armstrong breechloaders and the period of British rifled muzzle-loaders, British breechloaders were re-introduced in 1880. Early British Elswick breechloaders in the 1880s used a steel cup obturation method and this was quickly superseded in guns designed by the Royal Gun Factory by the French de Bange method, the basic principle of which is still in use today. In British service this became a Crossley pad with an interrupted thread screw block e. g. a Welin screw, the shell was loaded via the breech, followed by the propellant charge in a cloth bag. A single-use vent sealing tube, a type of primer not dissimilar in appearance to a rifle round, was inserted into the breech for firing the gun. For instance, Britain before World War I had both QF and BL6 inch guns and this presented difficulties for BL guns at high angles. A special cartridge was developed for BL9.2 inch guns on H. A. mountings, using multiple small fabric bags also allows the gunners to use a reduced charge if need be. The term BLC stood for BL converted and referred to a breech and breech mechanism modified from an early long-screw three- or four-motion to modern short-screw single-motion, an example is the conversion of the BL15 pounder to BLC15 pounder. Calibre radius head, the radius of a circle with the curve of the nose on its circumference. The longer and more pointed the nose, the higher the C. R. H. Typical C. R. H. for British shells leading up to World War I was two, e. g. the curve of the nose of a two C. R. H. Six-inch shell was equivalent to the curve of a circle with a radius of 12 inches, shells of four C. R. H. were soon developed in World War I, identified by an A following the shell mark number, B for six and so on. For modern streamlined shells post-World War I, two numbers were necessary to more correctly denote a shells C. R. H, for instance, the World War I6 inch 26 cwt howitzer shell was two C. R. H. The World War II Mk 2D shell was correctly described as 5/10 C. R. H, in this use it is synonymous with round
