History of Tank

Tanks 
Problems come up against as he pinned down the enemy has been around since ancient times. The idea of ​​using an object moves to protect from projectiles also have emerged since time immemorial. Ancient Greeks used the tower called Helepolis assault. Roman Empire towers coated wear protective shooting using katapult. In the Middle Ages, Poland and thech Republic has made a coated steel chariots. And Leonardo da Vinci had designed a wheeled vehicle of war. 

These concepts focus more on long into the raid the castle, where tactics and formations are not needed. But technological developments of the Industrial Revolution made the war into a giant stampede; the trench warfare.
World War I
Conditions battles of World War I on the Western Front made the British Army thought to develop vehicles that can cross the trench, destroying the barbed wire and machine guns shot does not work. Tank prototype was first tested by the British military on September 6, 1915. At first, this vehicle is named "land boat" (ground ship), but to keep the secret, early versions of tanks called "water carrier" which then shortened as the "tank" (water tank in English). The term is used for tanks that make workers think that they are making water transport vehicles for the British army in Mesopotamia (now Iraq). The term tank was finally inaugurated on December 24, 1915                                  . Tanks first used in war when Captain H. W. Mortimore carrying tanks Mark I in the Battle of the Somme on 15 September 1916. French developed the Schneider CA1 tanks are made from Holt Caterpillar tractors, and was first used on April 16, 1917.The use of massive tanks in combat occurred at the Battle of Cambrai on November 21, 1917. And then the tanks can be successfully used in the Battle of Amiens, where the Allies broke the German defensive trenches with the help of armored vehicles.The role of tanks will eventually make trench warfare obsolete concept, with thousands of tanks made by France and Britain. At first, the use of tanks have varying results. Problems such as performance of tanks that can not be relied upon. And the first tanks have low power, both guns and machine capabilities, as well as a weak layer of steel. The use of tanks in small groups also reduce the impact of the resulting tank. German troops were surprised and not have a weapon that can stop the tanks, but they finally managed to find an anti-tank fire, and digging trenches longer also succeeded in halting the British tanks. The changes to the battlefield and the poor performance of tanks forcing the Allies to continue to develop the concept of this tank. Tank continued to expand in World War I, for instance Mark V tanks, which made very long so it can pass through a wide trenches though
The period between two wars
Vickers Independent A1E1 tank made in England was canceled and did not enter the production line, but influence the design a lot of other tanks. With the formation of the concept of a tank, in the period between world wars a number of countries began to develop and produce tanks respectively. British-made tanks are the most sophisticated, because the British wanted to make armor since the 1920's. France and Germany did not pursue the development of tanks at this time, given the poor economic conditions, and the Versailles Treaty that limits the Germans. The United States also does not much develop their armored vehicles, because the available funds more widely used for the development of cavalry. At this time, developed a wide range of tank classes, especially in England. Light tanks, which weigh less than ten tons, used for monitoring tasks, and armed only with light machine guns are only effective against light tanks used other. Tank or tanks being cruiser, heavier and intended to travel quickly over long distances. And last, heavy tank or infantry tanks, tanks with a protective coating is heavy, slow running.These tanks are made to be used to penetrate the defense together with the infantry.Protector which can last shot makes heavy anti-tank weapons. After the heavy tank and infantry managed to pierce the opponent's defense line, the tanks are to be sent through these holes and attacks the line of logistics and unit commanders. Such tactics ultimately dikembangankan by Germany in the concept of blitzkrieg.
World War II
World War II found that the rapid development of the tank. Germany for example, using light tanks like the Panzer I, which was previously used only for practice. Light tanks and other armored vehicles into the most important element in the Blitzkrieg.However, it loses face light tanks and more British tanks against Soviet T-34 tanks.And at the end of the war all sides have been drastically increase the size of cannon and tank protector. For example, the Panzer I wear only two machine guns, and the Panzer IV, the heaviest German tanks at the beginning of World War II using a low speed 75 mm cannon, and weighing under 20 tons. At the end of the war, the tank is standard German, Panther, using high-speed 75 mm cannon, and weighs 45 tons. Another wartime developments is the introduction of a suspension system that much better. Maybe this sounds unimportant, but the quality is a determinant of performance suspension cross-country tanks. Tank with a bad suspension will result in vibrations felt riders, this will result in operating difficulties, reduce speed, and create an advanced shooting while walking impossible. The new suspension system as the Christie suspension system or torsion bar suspension enhance performance and speed dramatically. At this time almost all the tanks are equipped with radios to facilitate briefings and communications. Tank body has also been modified to be used for other roles, such as the destruction of mines and the role of combat engineers. All the major countries of participants of war has developed its own motion-cannon: artillery, tank destroyers and assault guns. Germany and the Soviet assault cannon, cheaper and lighter than a tank, use the cannons of the most severe. While the tank destroyer of the United States and Britain are difficult to distinguish from regular tanks. Rotating cannon, which was not previously available on all tanks, considered as very important. This gun should be used against other tanks, so sought for and as strong as possible, means the tank has a cannon enough to be very strong. As a result, the design of tanks with many guns, like the Soviet T-35, abandoned.
Cold War and beyond
Polish tank company who wore T-54. After World War II and into the Cold War, superpower nations and developed countries draw lessons from the German tanks in the use of force. Coupled with the threat of nuclear war and the chemical that makes tanks equipped with nuclear and chemical warfare equipment. Advances in technology make the tank cannon and ammunition increasingly feared, and each country vying to perfect its technology. But it was the biggest threat today is the tank infantry troops equipped with light weaponry destroyed yan has tremendous power, by developing an anti-tank basoka which also results in the development of the bazooka Germany in World War II.Coupled with the rapid development capabilities with the air force helicopter gunships that have anti-tank capability.
