MK. IV - WWI HEAVY TANK  1/35

The Mark V tank is a British tank, often classified as a WWI heavy tank. The first prototypes of this vehicle appeared in late 1917, and series production began around 1917-1918. As a result, approximately 400 tanks of this type were produced. The vehicle was powered by a single Ricard engine with a power output of up to 150 hp, and its weight reached 30 tons. The vehicle's armament (in the so-called Male version) consisted of two 57 mm cannons and three machine guns, while the so-called Female version had five machine guns. The so-called Composite (or Hermaphrodite) version was armed with a single 57 mm cannon and four machine guns.

The Mark V was developed based on the Mark IV tank. It adopted key design principles from its predecessor, such as the diamond shape of the hull and tracks, the absence of a turret with armament, and the placement of sponsons on the sides of the vehicle. However, it received a new drive unit and, just as importantly, a different drivetrain and track turning mechanism. There was also an observation tower for the vehicle's commander. The tank was also much more mechanically sophisticated than its predecessor, and the thickness of the armor varied from 6 to 14 millimeters. Mark V tanks were first used in combat during the Battle of Hamel in July 1918. They were also widely used during the Battle of Amiens in August 1918. Interestingly, they were not permanently withdrawn from the British Army until the early 1930s!

The Mark I tank is a British tank, often classified as a WW1 heavy tank. The first prototypes of this vehicle appeared in 1916, and series production began in the same year. The vehicle was powered by a single carburetor engine with a power output of up to 105 hp. The length of the vehicle was 7.93 meters with a total width of 4.19 meters. The vehicle's armament (in the so-called Male version) consisted of two 57 mm cannons and three machine guns, while the so-called Female version had five machine guns.

The Mark I tank was the first British tank of the First World War to be used on a large scale and the first tank in history to be used in combat! It was developed based on assumptions and conclusions drawn from the operation of the prototype Little Willie tank. At the same time, however, it differed clearly from it in the location of the tracks or the shape of the hull, although it was powered by the same engine. The Mark I tank also introduced a diamond shape typical of British tanks from 1916-1918. The vehicle had no turret, and all armament was mounted on sponsons on the sides of the tank. The Mark I was first used in combat in September 1916 during the Battle of the Somme.

The Mark II tank is a British tank, often classified as a WW1 heavy tank. The first prototypes of this vehicle appeared in 1916, and series production resumed around 1916-1917. As a result, 50 tanks of this type were produced. The vehicle was powered by a single carburetor engine with a power output of 105 hp, and its weight ranged from 27 to 28 tons. The vehicle's armament (in the so-called Male version) consisted of two 57 mm cannons and three 8 mm Hotchkiss machine guns, while the so-called Female version had five machine guns, including one 8 mm Hotchkiss and four 7.7 mm Vickers.

The Mark II was developed based on the Mark I tank. It adopted key design principles from its predecessor, such as the diamond shape of the hull and tracks, the absence of a turret with armament, and the placement of sponsons on the sides of the vehicle. At the same time, it was assumed from the very beginning that the Mark II would be intended primarily for training tasks, and also to implement numerous, albeit relatively minor, mechanical improvements resulting from the use of Mark I vehicles used in the Battle of Arras in April and May 1917, but suffered heavy losses.

The Mark IV tank is a British tank, often classified as a WWI heavy tank. The first prototypes of this vehicle appeared in 1917, and series production continued in 1917-1918. As a result, approximately 1,220 tanks of this type were produced. The vehicle was powered by a single Daimler-Foster engine of up to 105 hp, and its weight ranged from 27 to 29 tons. The vehicle's armament (in the so-called Male version) consisted of two 57 mm caliber cannons and three 7.7 mm Lewis machine guns, while the so-called Female version had five 7.7 mm Lewis machine guns. The Mark IV was developed based on the Mark I tank. It adopted key design principles from its predecessor, such as the diamond shape of the hull and tracks, the absence of armament in a turrets, and the placement of armaments in sponsons on the sides of the vehicle. The main modernization involved significant reinforcement.
