Tanks are essentially weapon platforms that make the weapons mounted in them more effective by their cross-country mobility and by the protection they provide for their crews.
Weapons mounted in tanks have ranged from single rifle-calibre machine guns to, in recent years, long-barreled guns of 120- or 125-mm (4.72- or 4.92-inch) calibre., when horse-drawn war chariots were used in the Middle East by the Egyptians, Hittites, and others as mobile platforms for combat with bows and arrows.
This was clearly demonstrated in 1937 during the civil war in Spain, where T-26 and BT tanks were used by the Republican forces.
Even before this time, it had become clear that tanks that moved at the slow pace of the infantry and were therefore exposed to the full effect of antitank guns had to be thickly armoured.
The first tracked armoured vehicle was improvised in July 1915, in Britain, by mounting an armoured car body on a Killen-Strait tractor.
The vehicle was constructed by the Armoured Car Division of the Royal Naval Air Service, whose ideas, backed by the First Lord of the Admiralty, Schneider) amounted to an armoured box on a tractor chassis; 400 were ordered in February 1916.
Before this division into mobile and slow tanks had crystallized, several different designs were tried.
The British Independent tank of 1925, with five turrets, started a trend toward multi-turreted heavy tanks.
This became inevitable with the appearance of the tracked agricultural tractor, but there was no incentive for this until after the outbreak of World War I.These tanks, however, were too slow and had too short an operating range to exploit the breakthrough.In consequence, demand grew for a lighter, faster type of tank, and in 1918 the 14-ton When World War I ended in 1918, France had produced 3,870 tanks and Britain 2,636. copy was the M1917 light tank, and the Italian was the Fiat 3000. remained the most numerous tank in the world into the early 1930s.The outbreak of World War I in 1914 radically changed the situation.Its opening stage of mobile warfare accelerated the development of armoured cars, numbers of which were quickly improvised in Belgium, France, and Britain.
