History and Development Christie used the experience gained before and during World War I to develop his "Convertible Suspension", which allowed a vehicle to run on either tracks or wheels. Most tanks of the time period weren't durable enough to be drive to the front on their own, so instead were delivered by trucks and then driven to where they were needed. The Convertible Suspension was designed to overcome this deficiency by allowing for high speed on roads using tires and then having the tracks installed on the tank before entering the battlefield. After developing several vehicles which culminated in the M.1919. The Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war.

QF 6-pounder 6 Cwt Hotchkiss
The Ordnance QF 6-pounder 6 cwt Hotchkiss Mk I and Mk II was a shortened version of the original QF 6 pounder Hotchkiss, QF 6 pounder Hotchkiss naval gun, and was developed specifically for use in the sponsons of the later Marks of British tanks in World War I, from Mark IV tank, Mark IV onwards. History World War I The original QF 6 pounder Hotchkiss, QF 6 pounder naval gun had turned out to be too long for practical use with the current British heavy tank designs, which mounted guns in sponsons on the side rather than turrets on top as modern tanks do. The Muzzle (firearm), muzzles of the long barrels sometimes dug into the mud or struck obstacles when the vehicle crossed Trench warfare, trenches or shell craters. The shortened QF 6 pounder 6 cwt Mk I of single tube construction was introduced in January 1917 in the Mark IV tank, and may be considered the world's first specialised tank gun. The shortened barrel incurred a reduction in muzzle velocity, but as tank guns in World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interwar Tanks Of The United States
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the First World War to the beginning of the Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the developed world. The indulgences of the era subsequently were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies. Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I, and ended with the rise o ...
