Yugoslavia
–
Yugoslavia was a country in Southeast Europe during most of the 20th century. The Serbian royal House of Karađorđević became the Yugoslav royal dynasty, Yugoslavia gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris. The country was named after the South Slavic peoples and constituted their first union, following centuries in which the territories had been part of the Ottoman Empire, renamed the Kingdom of Yugoslavia on 3 October 1929, it was invaded by the Axis powers on 6 April 1941. In 1943, a Democratic Federal Yugoslavia was proclaimed by the Partisan resistance, in 1944, the king recognised it as the legitimate government, but in November 1945 the monarchy was abolished. Yugoslavia was renamed the Federal Peoples Republic of Yugoslavia in 1946 and it acquired the territories of Istria, Rijeka, and Zadar from Italy. Partisan leader Josip Broz Tito ruled the country as president until his death in 1980, in 1963, the country was renamed again as the Socialist Federal Republic of Yugoslavia. The constituent six socialist republics that made up the country were the SR Bosnia and Herzegovina, SR Croatia, SR Macedonia, SR Montenegro, SR Serbia, and SR Slovenia. Serbia contained two Socialist Autonomous Provinces, Vojvodina and Kosovo, which after 1974 were largely equal to the members of the federation. After an economic and political crisis in the 1980s and the rise of nationalism, Yugoslavia broke up along its republics borders, at first into five countries, eventually, Serbia and Montenegro accepted the opinion of the Badinter Arbitration Committee about shared succession. Serbia and Montenegro themselves broke up in 2006 and became independent states, the concept of Yugoslavia, as a single state for all South Slavic peoples, emerged in the late 17th century and gained prominence through the Illyrian Movement of the 19th century. The name was created by the combination of the Slavic words jug, Yugoslavia was the result of the Corfu Declaration, as a project of the Serbian Parliament in exile and the Serbian royal Karađorđević dynasty, who became the Yugoslav royal dynasty. The country was formed in 1918 immediately after World War I as the Kingdom of Serbs, Croats and Slovenes by union of the State of Slovenes, Croats and Serbs and it was commonly referred to at the time as the Versailles state. Later, the government renamed the country leading to the first official use of Yugoslavia in 1929, on 6 January 1929 King Alexander I suspended the constitution, banned national political parties, assumed executive power and renamed the country Yugoslavia. He hoped to curb separatist tendencies and mitigate nationalist passions and he imposed a new constitution and relinquished his dictatorship in 1931. None of these three regimes favored the policy pursued by Alexander I, Alexander attempted to create a centralised Yugoslavia. He decided to abolish Yugoslavias historic regions, and new internal boundaries were drawn for provinces or banovinas, the banovinas were named after rivers. Many politicians were jailed or kept under police surveillance, the effect of Alexanders dictatorship was to further alienate the non-Serbs from the idea of unity. During his reign the flags of Yugoslav nations were banned, Alexander was succeeded by his eleven-year-old son Peter II and a regency council headed by his cousin, Prince Paul

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

Syria
–
Syrias capital and largest city is Damascus. Religious groups include Sunnis, Christians, Alawites, Druze, Mandeans, Shiites, Salafis, Sunni Arabs make up the largest religious group in Syria. Its capital Damascus and largest city Aleppo are among the oldest continuously inhabited cities in the world, in the Islamic era, Damascus was the seat of the Umayyad Caliphate and a provincial capital of the Mamluk Sultanate in Egypt. The post-independence period was tumultuous, and a number of military coups. In 1958, Syria entered a union with Egypt called the United Arab Republic. Syria was under Emergency Law from 1963 to 2011, effectively suspending most constitutional protections for citizens, Bashar al-Assad has been president since 2000 and was preceded by his father Hafez al-Assad, who was in office from 1970 to 2000. Mainstream modern academic opinion strongly favours the argument that the Greek word is related to the cognate Ἀσσυρία, Assyria, in the past, others believed that it was derived from Siryon, the name that the Sidonians gave to Mount Hermon. However, the discovery of the inscription in 2000 seems to support the theory that the term Syria derives from Assyria. The area designated by the word has changed over time, since approximately 10,000 BC, Syria was one of centers of Neolithic culture where agriculture and cattle breeding appeared for the first time in the world. The following Neolithic period is represented by houses of Mureybet culture. At the time of the pre-pottery Neolithic, people used vessels made of stone, gyps, finds of obsidian tools from Anatolia are evidences of early trade relations. Cities of Hamoukar and Emar played an important role during the late Neolithic, archaeologists have demonstrated that civilization in Syria was one of the most ancient on earth, perhaps preceded by only those of Mesopotamia. The earliest recorded indigenous civilisation in the region was the Kingdom of Ebla near present-day Idlib, gifts from Pharaohs, found during excavations, confirm Eblas contact with Egypt. One of the earliest written texts from Syria is an agreement between Vizier Ibrium of Ebla and an ambiguous kingdom called Abarsal c.2300 BC. The Northwest Semitic language of the Amorites is the earliest attested of the Canaanite languages, Mari reemerged during this period, and saw renewed prosperity until conquered by Hammurabi of Babylon. Ugarit also arose during this time, circa 1800 BC, close to modern Latakia, Ugaritic was a Semitic language loosely related to the Canaanite languages, and developed the Ugaritic alphabet. The Ugarites kingdom survived until its destruction at the hands of the marauding Indo-European Sea Peoples in the 12th century BC, Yamhad was described in the tablets of Mari as the mightiest state in the near east and as having more vassals than Hammurabi of Babylon. Yamhad imposed its authority over Alalakh, Qatna, the Hurrians states, the army of Yamhad campaigned as far away as Dēr on the border of Elam

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

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

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

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

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