Merritt–Brown Triple Differential Tank Transmission
Tank steering systems allow a tank, or other continuous track vehicle, to turn. Because the tracks cannot be angled relative to the hull (in any operational design), steering must be accomplished by speeding one track up, slowing the other down (or reversing it), or a combination of both. Half-track vehicles avoid this by combining steerable wheels and fixed-speed tracks. Early steering systems were adopted from tracked work vehicles, generally using a clutch to reduce power to one track, causing it to slow down. These designs have numerous problems, notably when climbing hills or running at high speed, as the reduction in power causes the overall speed to slow. Delivering power to both tracks while turning them at different speeds is a difficult design problem. A series of more advanced designs were introduced, especially through World War II, that maintained power to both tracks during steering, a concept known as regenerative steering. Some also allowed one track to move forw ...

Tank Controls
Tank controls are a control system used in Video game, video games whereby players control movement relative to the position of the player character, rather than the perspective of the Virtual camera system, game camera. Mechanism In a game with tank controls, pressing up (for example on a D-pad, analog stick, or Arrow keys, cursor movement keys) on the game controller moves the character in the direction they face, down reverses them, and left and right rotates them. This differs from many 3D games, in which characters move in the direction players push from the perspective of the Virtual camera system, camera. The term "tank controls" comes from the Tank steering systems, steering mechanisms of old tanks, which had to stop completely before turning. Tank controls were common in 3D games in the 1990s, such as ''Grim Fandango'' and the early ''Resident Evil'' and ''Tomb Raider'' games. Tank controls allow players to maintain a direction when the camera angle changes. ''Grim Fa ...

Covenanter Tank
The Cruiser tank Mk V or A13 Mk III Covenanter was a British cruiser tank of the Second World War. The Covenanter was the first cruiser tank design to be given a name. Designed by the London, Midland and Scottish Railway as a better-armoured replacement for the Cruiser Mark IV, it was ordered into production in 1939 before pilot models were built. Problems with the design became apparent only after production was under way. The tank equipped various British armoured divisions for home defence and training. It never left the UK as poor engine cooling caused the Mk I to Mk III to be declared unfit for overseas service especially in hot climates. This was rectified in the Mk IV after many corrective actions were undertaken but, by February 1944, it was declared obsolete. More than 1,700 of the type were built. It was named after the Covenanters, a Scottish religious faction at the time of the Wars of the Three Kingdoms. Development In 1938, the War Office had issued a requireme ...

Panzer IV
The ''Panzerkampfwagen'' IV (Pz.Kpfw. IV), commonly known as the ''Panzer'' IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161. The Panzer IV was the most numerous German tank and the second-most numerous German fully tracked armoured fighting vehicle of the Second World War; 8,553 Panzer IVs of all versions were built during World War II, only exceeded by the StuG III assault gun with 10,086 vehicles. Its chassis was also used as the base for many other fighting vehicles, including the Sturmgeschütz IV assault gun, the Jagdpanzer IV self-propelled anti-tank gun, the ''Wirbelwind'' self-propelled anti-aircraft gun, and the '' Brummbär'' self-propelled gun. The Panzer IV saw service in all combat theatres involving Germany and was the only German tank to remain in continuous production throughout the war. It was originally designed for infantry support, while the sim ...

Panzer III
The ''Panzerkampfwagen III'', commonly known as the Panzer III, was a medium tank developed in the 1930s by Germany, and was used extensively in World War II. The official German ordnance designation was Sd.Kfz. 141. It was intended to fight other armoured fighting vehicles and serve alongside and support the similar Panzer IV, which was originally designed for infantry support. However, as the Germans faced the formidable T-34, more powerful anti-tank guns were needed, and since the Panzer IV had more development potential with a larger turret ring, it was redesigned to mount the long-barrelled 7.5 cm KwK 40 gun. The Panzer III effectively swapped roles with the Panzer IV, as from 1942 the last version of the Panzer III mounted the 7.5 cm KwK 37 L/24 that was better suited for infantry support. Production of the Panzer III ceased in 1943. Nevertheless, the Panzer III's capable chassis provided hulls for the Sturmgeschütz III assault gun until the end of the war. Development h ...

T-34
The T-34 is a Soviet medium tank introduced in 1940. When introduced its 76.2 mm (3 in) tank gun was less powerful than its contemporaries while its 60-degree sloped armour provided good protection against Anti-tank warfare, anti-tank weapons. The Christie suspension was inherited from the design of American J. Walter Christie's M1928 tank, versions of which were sold turret-less to the Red Army and documented as "farm tractors", after being rejected by the U.S. Army. The T-34 had a profound effect on the conflict on the Eastern Front (World War II), Eastern Front in the World War II, Second World War, and had a short lasting impact on tank design. After the Germans encountered the tank in 1941 during Operation Barbarossa, German general Paul Ludwig Ewald von Kleist called it "the finest tank in the world" and Heinz Guderian affirmed the T-34's "vast superiority" over German tanks. Alfred Jodl, chief of operations staff of the German armed forces noted in his war diar ...

T-35
The T-35 was a Soviet multi- turreted heavy tank of the interwar period and early Second World War that saw limited production and service with the Red Army. Often called a land battleship, it was the only five-turreted heavy tank in the world to reach production, but proved to be slow and mechanically unreliable. Most of the T-35 tanks still operational at the time of Operation Barbarossa were lost due to mechanical failure rather than enemy action. It was designed to complement the contemporary T-28 medium tank; however, very few were built. Outwardly, it was large; but internally, the spaces were cramped with the fighting compartments separated from each other. Some of the turrets obscured the entrance hatches. Production history The T-35 was developed by the OKMO design bureau of the Bolshevik Factory, which began work on a heavy tank in 1930. Two teams developed separate designs. The team headed by German engineer Grotte worked on the 100-ton four-turreted TG-5 tank, ar ...

Vickers Independent
The Independent A1E1 is a multi-turreted tank that was designed by the British armaments manufacturer Vickers between the First and Second World Wars. Although it only ever reached the prototype stage and only a single example was built, it influenced many other tank designs. The A1E1 design can be seen as a possible influence on the Soviet T-100 and T-28 tanks, the German ''Neubaufahrzeug'' tanks, and the British Medium Mk III and Cruiser Mk I (triple turret) tank designs. The Soviet T-35 tank was heavily influenced by its design. Design The Independent was a multi-turret design, having a central gun turret armed with the 3 pounder (47 mm) gun, and four subsidiary turrets each armed with a 0.303 inch Vickers machine gun. The subsidiary turrets were mounted two at the front and two to the rear of the turret (about halfway along the hull). The gun of the left rear turret was able to elevate to engage aircraft. The tank was designed to have heavy firepower, self-defence capabil ...

Type 99 Tank
The Type 99 () or ZTZ-99 is a Chinese third generation main battle tank (MBT).US Army TRADOC Intelligence Support Activity (2011:5-40) The vehicle was a replacement for the aging Type 88 introduced in the late 1980s. The Type 99 MBT was China's first mass-produced third-generation main battle tank. Combining modular composite armour and tandem-charge defeating ERA, 125 mm smoothbore gun with ATGM-capability, high mobility, digital systems and optics, the Type 99 represents a shift towards rapid modernization by the PLA. The tank entered People's Liberation Army (PLA) service in 2001. The People's Liberation Army Ground Force (PLAGF) is the sole operator of the Type 99. Three main versions of the Type 99 have been deployed, the Type 98 prototype, Type 99 and the Type 99A. The Type 99 forms the core of China’s modern maneuver combat capabilities, with over 1,200 tanks built for the past two decades. Development The development of China's domestic third generation MBT was ...

T-90
The T-90 is a third-generation Russian main battle tank. It uses a 125mm 2A46 smoothbore main gun, the 1A45T fire-control system, an upgraded engine, and gunner's thermal sight. Standard protective measures include a blend of steel and composite armour, smoke grenade dischargers, Kontakt-5 explosive reactive armour (ERA) and the Shtora infrared anti-tank guided missile (ATGM) jamming system. The T-90 was designed and built by Uralvagonzavod, in Nizhny Tagil, Russia. It entered service with the Russian Army in 1992. Development The T-90 has its origins in a Soviet-era program aimed at developing a single replacement for the T-64, T-72 and T-80 series of main battle tanks. The T-72 platform was selected as the basis for the new generation of tank owing to its cost-effectiveness, simplicity and automotive qualities. The Kartsev-Venediktov Design Bureau from Nizhny Tagil was responsible for the design work and prepared two parallel proposals—the ''Object 188'', which was a re ...

T-72
The T-72 is a family of Soviet/Russian main battle tanks that entered production in 1969. The T-72 was a development of the T-64, which was troubled by high costs and its reliance on immature developmental technology. About 25,000 T-72 tanks have been built, and refurbishment has enabled many to remain in service for decades. It has been widely exported and has seen service in 40 countries and in numerous conflicts. The T-90 introduced in 1992 is a development of the T-72B; production and development of various modernized T-72 models continues today. Development Development from the T-64 The T-72 was a product of a rivalry between design teams. Morozov KB was led by Alexander Morozov in Kharkiv. Uralvagon KB was led by Leonid Kartsev in Nizhny Tagil. To improve on the T-62, two designs based on the tank were tested in 1964: Nizhny Tagil's Object 167 (T-62B) and Kharkiv's Object 434. Ob. 434 was a technically ambitious prototype. Under the direction of Morozov in Kharkiv, a ...

T-64
The T-64 is a Soviet tank manufactured in Kharkiv, and designed by Kharkiv Morozov Machine Building Design Bureau. The tank was introduced in the early 1960s. It was a more advanced counterpart to the T-62: the T-64 served in tank divisions, while the T-62 supported infantry in motorized rifle divisions. It introduced a number of advanced features including composite armour, a compact engine and transmission, and a smoothbore 125-mm gun equipped with an autoloader to allow the crew to be reduced to three so the tank could be smaller and lighter. In spite of being armed and armoured like a heavy tank, the T-64 weighed only . Soviet military planners considered the T-64 the first of the third-generation tanks and the first main battle tank. These features made the T-64 expensive to build, significantly more so than previous generations of Soviet tanks. This was especially true of the powerpack, which was time-consuming to build and cost twice as much as more conventional designs. S ...
