In guns , particularly firearms , caliber ( or calibre in British English ) is the specified nominal internal diameter of the gun barrel bore regardless of how or where the bore is measured and whether or not the finished bore matches that specification . It is measured in inches to an accuracy of hundredths or thousandths of an inch or in millimeters . For example , a .45 caliber firearm has a barrel diameter of roughly 0.45 inches ( 11 mm ) . Barrel diameters can also be expressed using metric dimensions . For example , a 9 mm pistol has a barrel diameter of about 9 millimeters . Due to the inaccuracy and imprecision of imperial dimensions converted to metric units , metric designations are typically far out of specifications published in decimal inches . True caliber specifications require imperial measure , and even when cartridge designations ( often mistakenly referred to as caliber ) only specify caliber to even tenths or hundredths of an inch , actual barrel/chamber/projectile dimensions are published to at least thousandths of an inch and frequently tolerances extend into ten-thousandths of an inch . In a rifled barrel , the distance is measured between opposing lands or between opposing grooves ; groove measurements are common in cartridge designations originating in the United States , while land measurements are more common elsewhere in the world . Measurements across the grooves are used for maximum precision because rifling and the specific caliber so-measured is the result of final machining process which cuts grooves into the rough bore leaving the lands behind . Good performance requires a concentric , straight bore that accurately centers the projectile within , in preference to a tight fit which can be achieved even with off-center , crooked bores that cause excessive friction , fouling and an out-of-balance , wobbling projectile in flight . While modern firearms are generally referred to by the name of the cartridge the gun is chambered for , they are still categorized together based on bore diameter . For example , a firearm might be described as a 30 caliber rifle , which could be any of a wide range of cartridges using a roughly 0.30 inches ( 7.6 mm ) projectile ; or a 22 rimfire , referring to any rimfire firearms firing cartridges with a .22 caliber projectile .
The 37 mm Gun Motor Carriage M6 , also known as M6 Fargo , and under the manufacturer ( Dodge ) 's designation WC55 , was a modified Dodge WC52 light truck mounting a light anti-tank gun . It was used by the United States Army for infantry support and as a mobile anti-tank gun . It operated from late 1942 to January 1945 in the Mediterranean , European , and Pacific theaters of World War II . The M6 saw limited use during the war , and was poorly suited to modern warfare as it was unarmored and was armed with a too small caliber gun . Being required to back into firing positions rather than forward firing proved to be a deficiency .
The United States of America ( USA ) , commonly known as the United States ( U.S. or US ) or America , is a country consisting of 50 states , a federal district , five major self-governing territories , and various possessions . [ g ] At 3.8 million square miles ( 9.8 million km2 ) , it is the world 's third or fourth-largest country by total area [ b ] and is slightly smaller than the entire continent of Europe . Most of the country is located in central North America between Canada and Mexico . With an estimated population of over 328 million , the U.S. is the third most populous country in the world . The capital is Washington , D.C. , and the most populous city is New York City . Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago . European colonization began in the 16th century . The United States emerged from the thirteen British colonies established along the East Coast . Numerous disputes between Great Britain and the colonies led to the American Revolutionary War lasting between 1775 and 1783 , leading to independence . The United States embarked on a vigorous expansion across North America throughout the 19th century - gradually acquiring new territories , displacing Native Americans , and admitting new states - until by 1848 it spanned the continent . During the second half of the 19th century , the American Civil War led to the abolition of slavery in the United States . The Spanish-American War and World War I confirmed the country 's status as a global military power .
France ( French : [ fʁɑ̃s ] ( listen ) ) , officially the French Republic ( French : République française , pronounced [ ʁepyblik fʁɑ̃sɛːz ] ( listen ) ) , is a country whose territory consists of metropolitan France in Western Europe and several overseas regions and territories . [ XIII ] The metropolitan area of France extends from the Mediterranean Sea to the English Channel and the North Sea , and from the Rhine to the Atlantic Ocean . It is bordered by Belgium , Luxembourg and Germany to the northeast , Switzerland and Italy to the east , and Andorra and Spain to the south . The overseas territories include French Guiana in South America and several islands in the Atlantic , Pacific and Indian oceans . The country 's 18 integral regions ( five of which are situated overseas ) span a combined area of 643,801 square kilometres ( 248,573 sq mi ) and a total population of 67.02 million ( as of July 2019 [ update ] ) . France is a unitary semi-presidential republic with its capital in Paris , the country 's largest city and main cultural and commercial centre . Other major urban areas include Lyon , Marseille , Toulouse , Bordeaux , Lille and Nice . France , including its overseas territories , has the most number of time zones of any country , with a total of 12 . During the Iron Age , what is now metropolitan France was inhabited by the Gauls , a Celtic people . Rome annexed the area in 51 BC , holding it until the arrival of Germanic Franks in 476 , who formed the Kingdom of Francia . The Treaty of Verdun of 843 partitioned Francia into East Francia , Middle Francia and West Francia . West Francia , which became the Kingdom of France in 987 , emerged as a major European power in the Late Middle Ages , following its victory in the Hundred Years ' War ( 1337-1453 ) .
The Panzerjäger I ( English : Tank Hunter 1 ) was the first of the German tank destroyers to see service in the Second World War . It mounted a Czech Škoda 4.7 cm ( 1.9 in ) cm PaK ( t ) anti-tank gun on a converted Panzer I Ausf . B chassis . It was intended to counter heavy French tanks like the Char B1 that were beyond the capabilities of the 3.7 cm PaK 36 anti-tank gun and served to extend the life of the obsolete Panzer I tank chassis . 202 Panzer I were converted to the Panzerjäger I in 1940 and 1941 . They were employed in the Battle of France , in the North Africa Campaign and on the Eastern Front .
Nazi Germany is the common English name for Germany between 1933 and 1945 , when Adolf Hitler and his Nazi Party ( NSDAP ) controlled the country through a dictatorship . Under Hitler 's rule , Germany became a totalitarian state where nearly all aspects of life were controlled by the government . The official name of the state was Deutsches Reich ( German Reich ) until 1943 and Großdeutsches Reich ( Greater German Reich ) from 1943 to 1945 . Nazi Germany is also known as the Third Reich ( Drittes Reich ) , meaning Third Realm or Third Empire , the first two being the Holy Roman Empire ( 800-1806 ) and the German Empire ( 1871-1918 ) . The Nazi regime ended after the Allies defeated Germany in May 1945 , ending World War II in Europe . Hitler was appointed Chancellor of Germany by the President of the Weimar Republic , Paul von Hindenburg , on 30 January 1933 . The NSDAP then began to eliminate all political opposition and consolidate its power . Hindenburg died on 2 August 1934 and Hitler became dictator of Germany by merging the offices and powers of the Chancellery and Presidency . A national referendum held 19 August 1934 confirmed Hitler as sole Führer ( leader ) of Germany . All power was centralised in Hitler 's person and his word became the highest law . The government was not a coordinated , co-operating body , but a collection of factions struggling for power and Hitler 's favour . In the midst of the Great Depression , the Nazis restored economic stability and ended mass unemployment using heavy military spending and a mixed economy .
The Semovente L. 40 da 47/32 was an Italian self-propelled gun built during World War II . It was created by mounting a Cannone da 47/32 anti-tank gun in an open-topped , box-like superstructure on a L 6/40 light tank chassis . Some were built as command tanks with a radio installed instead of the main gun . An 8 mm machine gun disguised as the 47 mm main gun was used on these versions to make them look like a regular Semovente 47/32s . About 300 Semoventi da 47/32 were built from 1941 onward . The Semovente da 47/32 was the most heavily armed Italian armoured fighting vehicle used on the Eastern Front . While the 47 mm gun was adequate for 1941 , by the time the Semovente reached the field it was already outdated and ineffective against enemy medium tanks , and therefore the vehicle was not particularly successful . After the Italian armistice in September 1943 , the German Army took all Semovente 47/32s they could get hold of for their own use . The German designation was StuG L6 47/32 630 ( i ) . Some of these were provided to Germany 's Croatian puppet state and the Slovene Home Guard .
Italy ( Italian : Italia [ iˈtaːlja ] ( listen ) ) , officially the Italian Republic ( Italian : Repubblica Italiana [ reˈpubblika itaˈljaːna ] ) , is a European country consisting of a peninsula delimited by the Alps and surrounded by several islands . Italy is located in south-central Europe , and it is also considered a part of Western Europe . The country covers a total area of 301,340 km2 ( 116,350 sq mi ) and shares land borders with France , Switzerland , Austria , Slovenia , and the enclaved microstates of Vatican City and San Marino . Italy has a territorial exclave in Switzerland ( Campione ) and a maritime exclave in the Tunisian Sea ( Lampedusa ) . With around 60 million inhabitants , Italy is the third-most populous member state of the European Union . The capital and largest city is Rome ; other major cities are Milan , Naples , Turin , Palermo , Genoa , Bologna , Florence and Venice . Due to its central geographic location in Southern Europe and the Mediterranean , Italy has historically been home to myriad peoples and cultures . In addition to the various ancient peoples dispersed throughout what is now modern-day Italy , the most predominant being the Indo-European Italic peoples who gave the peninsula its name , beginning from the classical era , Phoenicians and Carthaginians founded colonies mostly in insular Italy , Greeks established settlements in the so-called Magna Graecia of Southern Italy , while Etruscans and Celts inhabited central and northern Italy respectively . An Italic tribe known as the Latins formed the Roman Kingdom in the 8th century BC , which eventually became a republic with a government of the Senate and the People . The Roman Republic initially conquered and assimilated its neighbours on the Italian peninsula , eventually expanding and conquering parts of Europe , North Africa and Asia . By the first century BC , the Roman Empire emerged as the dominant power in the Mediterranean Basin and became a leading cultural , political and religious centre , inaugurating the Pax Romana , a period of more than 200 years during which Italy 's law , technology , economy , art , and literature developed . Italy remained the homeland of the Romans and the metropole of the empire , whose legacy can also be observed in the global distribution of culture , governments , Christianity and the Latin script .
The AEC Mk I Gun Carrier , known as Deacon , was a British armoured fighting vehicle of the Second World War . It was an attempt to make the QF 6 pounder anti-tank gun into a self-propelled artillery piece . It was employed only during the North African Campaign from 1942 to 1943 .
The United Kingdom of Great Britain and Northern Ireland , commonly known as the United Kingdom ( UK or U.K. ) or Britain , [ note 11 ] is a sovereign country located off the north­western coast of the European mainland . Existing under its current name since 1921 , the United Kingdom includes the island of Great Britain , the north­eastern part of the island of Ireland , and many smaller islands . Northern Ireland shares a land border with the Republic of Ireland . Otherwise , the United Kingdom is surrounded by the Atlantic Ocean , with the North Sea to the east , the English Channel to the south and the Celtic Sea to the southwest , giving it the 12th-longest coastline in the world . The Irish Sea separates Great Britain and Ireland . The total area of the United Kingdom is 94,000 square miles ( 240,000 km2 ) . The United Kingdom is a unitary parliamentary democracy and constitutional monarchy . [ note 12 ] The current monarch is Queen Elizabeth II , who has reigned since 1952 , making her the world 's longest-serving current head of state . The United Kingdom 's capital and largest city is London , a global city and financial centre with an urban area population of 10.3 million . Other major cities include Birmingham , Manchester , Glasgow , Leeds and Liverpool . The United Kingdom consists of four constituent countries : England , Scotland , Wales , and Northern Ireland . Their capitals are London , Edinburgh , Cardiff , and Belfast , respectively .
A portee is a truck that carries a gun on its bed , such that the gun is not fixed permanently to the vehicle , can be quickly unloaded and can be fired from the truck . While the term portee can be used to denote any truck carrying a gun on its bed , it is most often used to describe equipment used by British/Commonwealth forces in the North African Campaign of World War II . Modern terms for such vehicle are technical and/or gun truck .
The T48 57 mm Gun Motor Carriage was a self-propelled anti-tank gun produced by the Diamond T company in 1943 for the United States . The design incorporated a 57 mm gun M1 , a US production of the British Ordnance QF 6 pounder , mounted on an M3 Half-track . A total of 962 vehicles were produced from 1942 to 1943 . It had originally been planned that Britain would receive all of the examples produced through Lend-Lease , intending to use them in the Western Desert , but by the time they arrived the campaign was over . Additionally , the purpose-built M10 tank destroyer , armed with a 3-inch gun ( and later a 17-pounder gun in British service ) had begun to enter production . As a result , the British transferred 650 half-tracks to the Soviet Union under the Soviet Aid Program . Britain retained 30 and the remainder were taken by the US ; except for one kept by the U.S. Army , these British and American vehicles were converted back to standard M3 Half-tracks . The Soviets called it the SU-57 ( Samokhodnaya ustanovka 57 ) ; under this designation it served in Operation Bagration and other fighting on the Eastern Front during World War II .
The ZiS-30 was a light self-propelled anti-tank gun built for the Soviet Red Army in 1941 . It was based on the Komsomolets armoured artillery tractor . They were successful vehicles , but production was limited by the number of Komsomolets tractors still in use .
The Soviet Union , [ b ] officially known as the Union of Soviet Socialist Republics ( USSR or СССР ) , [ c ] was a federal sovereign state in northern Eurasia that existed from 1922 to 1991 . Nominally a union of multiple national Soviet republics , [ d ] in practice its government and economy were highly centralized . The country was a one-party state , governed by the Communist Party with Moscow as its capital in its largest republic , the Russian Soviet Federative Socialist Republic ( Russian SFSR ) . Other major urban centers were Leningrad , Kiev , Minsk , Tashkent , Alma-Ata , and Novosibirsk . It spanned over 10,000 kilometers ( 6,200 mi ) east to west across 11 time zones , and over 7,200 kilometers ( 4,500 mi ) north to south . Its territory included much of Eastern Europe , as well as part of Northern Europe and all of Northern and Central Asia . It had five climate zones : tundra , taiga , steppes , desert and mountains . The Soviet Union had its roots in the 1917 October Revolution , when the Bolsheviks , led by Vladimir Lenin , overthrew the Russian Provisional Government which had replaced the autocratic regime of Tsar Nicholas II during World War I . In 1922 , after a civil war ending in the Bolsheviks ' victory , the USSR was formed by a treaty which united the Russian , Transcaucasian , Ukrainian and Byelorussian republics . Following Lenin 's death in 1924 and a brief power struggle , Joseph Stalin came to power in the mid-1920s . Stalin formalized the Communist Party 's ideology of Marxism-Leninism and replaced the market economy with a command economy which led to a period of rapid industrialization and collectivization . During this period , rapid economic development resulted in dramatic improvements in the average standard of living , particularly in urban areas .
The Jagdpanzer 38 ( Sd.Kfz . 138/2 ) , was a German light tank destroyer of the Second World War based on a modified Czechoslovakian Panzer 38 ( t ) chassis . German armored forces in World War II created a variety of vehicles by mounting anti-tank guns on obsolete tank chassis . These machines performed even better than expected , yet were still vulnerable due to high vehicle profiles and open-topped turrets . Allied bombings took a heavy toll on German production facilities , and further increased the need for an easily produced yet effective light tank destroyer to replace vehicles like the StuG III and Marder series . Prototypes of the Jagdpanzer 38 were ready by 1944 and mass production began in April of that year . The Jagdpanzer 38 was covered entirely with sloped armor , and possessed a compact form and low silhouette , giving it much improved defensive ability over other self-propelled guns . Armament consisted of a 7.5 cm Pak 39 L/48 gun in fixed mounting as well as a remote-controlled MG 34 . It featured a wide body to accommodate the four-man crew , as well as strengthened lower hull with enlarged wheels , guide rollers and tracks . Jagdpanzer 38s first entered service in July 1944 , and would eventually be assigned to a number of units , including infantry , Panzerjäger and Volksgrenadier divisions . BMM and Škoda continually modified and improved the Jagdpanzer 38 during production of the more than 2,800 vehicles built . Owing to the ease of production and high operating rates , the Jagdpanzer 38 came to serve as Germany 's main tank destroyer in the latter period of the war , making an important contribution on both the Eastern and Western Fronts .
The Jagdpanzer IV , Sd.Kfz . 162 , was a German tank destroyer based on the Panzer IV chassis and built in three main variants . As one of the casemate-style turretless Jagdpanzer ( tank destroyer , literally hunting tank ) designs , it was developed against the wishes of Heinz Guderian , the inspector general of the Panzertruppen , as a replacement for the Sturmgeschütz III ( StuG III ) . Guderian objected against the needless , in his eyes , diversion of resources from Panzer IV tank production , as the Sturmgeschütz III was still more than adequate for its role . Officially , only the L/48-armed vehicle was named Jagdpanzer IV . The L/70-armed vehicle was named Panzer IV/70 . In this article , both versions are referred to in general as Jagdpanzer IV , except in the variants and surviving vehicles section .
The Marder I Marten ( Sd.Kfz . 135 ) was a German World War II tank destroyer , armed with a 75 mm PaK-40 anti-tank gun . Most Marder Is were built on the base of the Tracteur Blindé 37L ( Lorraine ) , a French artillery tractor/armoured personnel carrier of which the Germans had acquired more than three hundred after the Fall of France in 1940 .
The Marder II ( marten in English ) was a German tank destroyer of World War II based on the Panzer II chassis . There were two versions , the first mounted a modified Soviet 7.62 cm gun firing German ammunition , while the other mounted the German 7.5 cm Pak 40 gun . Its high profile and thin open-topped armor provided minimal protection to the crew . Nevertheless , the Marder II ( and similar Marder III ) provided a great increase in firepower over contemporary German tanks during 1942 and into 1943 . Only four Marder IIs remain today .
Marder III was the name for a series of World War II German tank destroyers . They mounted either Soviet 76.2 mm F-22 Model 1936 divisional field guns , or German 7.5 cm PaK 40 , in an open-topped fighting compartment on top of the chassis of the Panzer 38 ( t ) . They offered little protection to the crew , but added significant firepower compared to contemporary German tanks . They were in production from 1942 to 1944 and served on all fronts until the end of the war , along with the similar Marder II . The German word Marder means marten in English .
The Type 1 Gun tank Ho-Ni I ( 一式砲戦車 ホニ I , Isshiki ho-sensha Ho-Ni I ) was a tank destroyer and self-propelled artillery developed by the Imperial Japanese Army for use during World War II in the Pacific theater .
Japan ( Japanese : 日本 , Nippon [ ɲippoꜜɴ ] ( listen ) or Nihon [ ɲihoꜜɴ ] ( listen ) ) is an island country located in East Asia . It is bordered by the Sea of Japan to the west and the Pacific Ocean to the east , and spans more than 3,000 kilometers ( 1,900 mi ) along the coast of the continent from the Sea of Okhotsk in the north to the East China Sea and Philippine Sea in the south . Part of the Pacific Ring of Fire , Japan encompasses a stratovolcanic archipelago of about 6,852 islands , with five main islands ( Hokkaido , Honshu , Kyushu , Shikoku , and Okinawa ) comprising 97% of the country 's total area of 377,975 square kilometers ( 145,937 sq mi ) . Japan is officially divided into 47 prefectures and traditionally into eight regions . Approximately two-thirds of the country 's terrain is mountainous and heavily forested , and less than one-eighth of land is suitable for agriculture . Consequently , Japan is among the most densely populated and urbanized countries in the world , with over 90% of its population living in urban areas . The largest of these is the metropolitan area centered on the capital city of Tokyo , which is the most populous in the world and home to more than 38 million people . Japan itself is the world 's eleventh most populous country with a population of 126.2 million , of which 97.8% are ethnically Japanese . The kanji ( or Chinese characters ) that make up the name of Japan in the Japanese language mean sun origin ; in the Western world , the country is often known by the sobriquet Land of the Rising Sun . Periods of influence from other regions , primarily China , followed by periods of isolation , particularly from Western Europe , have characterized the history of Japan . While archaeological evidence indicates that Japan was inhabited as early as the Upper Paleolithic period , the first written mention of the archipelago appears in Chinese texts from the first century AD . Between the fourth and ninth centuries , the kingdoms of Japan became gradually unified under an Emperor and imperial court based in Heian-kyō ( modern Kyoto ) .
The Type 3 Gun tank Ho-Ni III ( 三式砲戦車 ホニIII , San-shiki hōsensha ) gun tank was a tank destroyer and self-propelled artillery of Imperial Japanese Army in World War II . The Type 3 Ho-Ni III superseded the Type 1 Ho-Ni I and its variant the Type 1 Ho-Ni II in production , and gave better protection to the crew due to having a completely enclosed superstructure .
The Mareșal was a tank destroyer produced in limited numbers during the Second World War by the Kingdom of Romania . In May 1944 , a German Waffenamt delegate acknowledged that the vehicle was the inspiration for the German Hetzer tank destroyer .
The Kingdom of Romania ( Romanian : Regatul României ) was a constitutional monarchy that existed in Romania from 26 March 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I , until 1947 with the abdication of King Michael I of Romania , and the Romanian parliament proclaiming Romania a people 's republic . From 1859 to 1877 , Romania evolved from a personal union of two vassal principalities ( Moldavia and Wallachia ) under a single prince to an autonomous principality with a Hohenzollern monarchy . The country gained its independence from the Ottoman Empire during the 1877-1878 Russo-Turkish War ( known locally as the Romanian War of Independence ) , when it also received Northern Dobruja in exchange for the southern part of Bessarabia . The kingdom 's territory during the reign of King Carol I , between 14 March ( O.S . ) ( 27 March ( N.S . ) ) 1881 and 27 September ( O.S . ) ( 10 October ( N.S . ) ) 1914 is sometimes referred as the Romanian Old Kingdom , to distinguish it from Greater Romania , which included the provinces that became part of the state after World War I ( Bessarabia , Banat , Bukovina , and Transylvania ) . With the exception of the southern halves of Bukovina and Transylvania , these territories were ceded to neighboring countries in 1940 , under the pressure of Nazi Germany or the Soviet Union . Following a disastrous World War II campaign on the side of the Axis powers and name change ( Legionary Romania ) , Romania joined the Allies in 1944 , recovering Northern Transylvania . The influence of the neighboring Soviet Union and the policies followed by Communist-dominated coalition governments ultimately led to the abolition of the monarchy , with Romania becoming a People 's Republic on the last day of 1947 .
The M3 Gun Motor Carriage ( GMC ) was a United States Army tank destroyer equipped with a 75 mm M1897A4 gun , which was built by the Autocar Company during World War II . After observing the new and often decisive , uses of armored vehicles on both sides during the French campaign of 1940 , the US Army decided that it required a 75 mm self-propelled gun , based on the chassis of the M3 Half-track . This was initially known as the T12 . However , after the addition of features such as the gun shield from the M2A3 ( a carriage for the M1897A4 ) , the new vehicle entered production under the name M3 Gun Motor Carriage ( or M3 GMC ) . Because the number of M2A3 gun shields available was insufficient for the M3 GMC order , a new gun shield was designed . Variants featuring the new shield were designated M3A1 GMC . The T12/M3 first served in the Philippines Campaign in 1942 with the Provisional Field Artillery Brigade in the anti-tank and the fire-support role . It then served in North Africa in tank destroyer battalions . It was used ineffectively in the Battle of Kasserine Pass and several other engagements , but was used with success in the Battle of El Guettar . It also served in the Allied invasion of Sicily , but was eventually superseded by the M10 tank destroyer . A total of 2,203 were produced , of which 1,361 were converted back into M3A1 half-tracks . The M3 GMC also served in the Pacific theater , starting with the Battle of Saipan .
The Self Propelled 17pdr , Valentine , Mk I , Archer was a British self propelled anti-tank gun of the Second World War based on the Valentine infantry tank chassis fitted with an Ordnance QF 17 pounder gun . Designed and manufactured by Vickers-Armstrongs , 655 were produced between March 1943 and May 1945 . It was used in North-West Europe and Italy during the war ; post-war , it served with the Egyptian Army . This vehicle was unusual in that its gun faced the rear of the chassis instead of the front .
The 17pdr SP Achilles ( officially 17 pounder , Self-Propelled , Achilles ) was a British variant of the American M10 tank destroyer armed with the British Ordnance QF 17 pounder high-velocity 76.2 mm ( 3 inch ) anti-tank gun in place of the M10 's considerably less powerful 3 inch ( 76.2 mm ) Gun M7 . A total of 1,100 M10s were converted to Achilles , making it the second most numerous armoured fighting vehicle to mount with the 17 pounder gun , behind the Sherman Firefly . The name Achilles was officially a designation applied to both the 3 gun and 17 pounder versions ( as Achilles I/II and Achilles Ic/IIc respectively ) but was little used during the Second World War ; at the time , the vehicle was called 17pdr M10 , or 17pdr SP M10 , or even occasionally , Firefly . It has since become identified almost exclusively with the 17 pounder version .
