===Development===
During the interwar period, British General Staff requested for a heavy tank design in 1924. The project, undertaken by an engineer named Walter Gordon Wilson, was designed by the Armstrong Siddeley engineering group. The finished prototype model was delivered to War Office in 1926. The design of the tank, named '''"Independent"''', was a multi-turreted design with a total of five turrets. The one in the center held a 3-pounder 47 mm gun while the other smaller turrets at the main turret's corner held Vickers machine guns. The tank can hold 8 crew members, a driver, four machine gunners, and three in the turret. It was around 28 tons and 25 feet long, despite being only 8 feet wide. This length caused some early problems as the tracks were too thin for the width, causing the rear sprocket wheels to peel the vehicle design as it continues to turn. W.G. Wilson attempted to fix this with an epicyclic steering system, but the tracks still wore out quickly. A unique feature on the Independent was a small opening on the left side of the tank that allowed for the placement of a stretcher for wounded crew members inside the tank to be pulled out from. <ref name="TankMuseumA1E1YT">TheTankMuseum 2016 Time.(3:00)</ref>

GarageImage Independent.jpg


The A1E1 Independent is a premium rank I British heavy tank with a battle rating of 1.3 (AB/RB/SB). It was introduced in Update 1.63 "Desert Hunters". The A1E1, with its five turrets, serve as the instigator of the multi-turreted concept that spread to the Soviet T-35 and the German Neubaufahrzeug.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • 47 mm gun is adequate
  • Large ammo reserve
  • One available ammo type makes it easier to use for beginners
  • A rare sight. Many players will not know where the critical components are
  • It has explosives in the AP rounds, very rare in British vehicles
  • Like other large tanks (eg T-35, T-28 and SMK) it is a very complex vehicle to destroy with plenty of turrets, big tracks and curvy/angled parts to soak up rounds and 8 crew members to boot

Cons:

  • Very long tank, hard to hide side from flankers
  • Only one ammo type
  • Armour is quite thin
  • Vulnerable to 20mm auto cannons. In many ways they are more effective than normal cannons due to their high rate of fire
  • APHE is inconsistent due to vehicles the Independent will be facing in general have less than 25 mm of armor

History

Development

During the interwar period, British General Staff requested for a heavy tank design in 1924. The project, undertaken by an engineer named Walter Gordon Wilson, was designed by the Armstrong Siddeley engineering group. The finished prototype model was delivered to War Office in 1926. The design of the tank, named "Independent", was a multi-turreted design with a total of five turrets. The one in the center held a 3-pounder 47 mm gun while the other smaller turrets at the main turret's corner held Vickers machine guns. The tank can hold 8 crew members, a driver, four machine gunners, and three in the turret. It was around 28 tons and 25 feet long, despite being only 8 feet wide. This length caused some early problems as the tracks were too thin for the width, causing the rear sprocket wheels to peel the vehicle design as it continues to turn. W.G. Wilson attempted to fix this with an epicyclic steering system, but the tracks still wore out quickly. A unique feature on the Independent was a small opening on the left side of the tank that allowed for the placement of a stretcher for wounded crew members inside the tank to be pulled out from. [1]

During the development and testing process, the Independent design was a item of espionage by the international community. Plans of the design ended up in the Soviet Union and in Germany, with a British officer named Norman Baillie-Stewart court-martialled for supplying secrets to the Germans, including the Independent plans. This espionage influenced several tank designs from these countries, with the T-28 and T-35 in the Soviet Union and the Neubaufahrzeug in Germany.

Cancellation

The Independent was tested by War Office all the way until 1935, but it was a troublesome design. Most of the tests focused on its automotive performance, not even passing along to gunnery trials. The Independent was also used in a officer school for recommendations and examinations. The only model built, the prototype, was deemed worn out in 1935 as the War Office saw no need to spend more money on the design when other vehicles were being produced. They retired the Independent and sent the model to the Bovington Tank Museum, where it sits today for display.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
