The M20 Dobermann is a Shalumite first-generation main battle tank that was introduced to service in 1950.

It was replaced by the M68 Braunbär.

Development

The Imperial Army Department of Tank Development, under commander the administration of Lord Jochen Behr, was issued the directive in late 1947 to design a new mainstay main battle tank capable of competing with those fielded by other Eraucran militaries. At the onset of the Great War, the Shalumite military had primarily fielded a fleet of light and medium tanks meant to act as cavalry support for mechanized and motorized units. While capable against opposing infantry groups, they lacked the necessary staying power to combat the more numerous and capable Æsthurlavaj vehicles. The Imperial Army, in an attempt to create a solution to the issue, pressed a heavier tank into service after reviewing several competing designs from manufacturers across the country. While equipped with much heavier firepower and armor, they greatly lacked in mobility and suffered from numerous reliability and maintenance issues. This forced the Imperial Army to rely more on foreign imports such as the Acrean Strv 72 and Strv 81 until the end of the conflict.

Lord Behr, who had worked alongside allied engineers throughout the war, wanted to avoid the poor performance that past models fielded by the army had experienced. To do this, he sought to replicate the emphasis placed on reliability by their Acrean counterparts. After observing several blueprints and designs, which generally fell within the specifications outlined by his department, it was decided that the production contract would be rewarded to Askvig Defense Services AG based out of Dresden. Their prototypes featured thicker armor capable of withstanding direct hits from the Acrean 88mm guns, improved firepower in the form of a 105mm rifled cannon, telescopic gunner sights that allowed for more accurate engagement while on the move, a more reliable powertrain, and a periscope instead of viewing slits. It was renamed from Armored Project 87, a placeholder which had been assigned by its designers, to the M20 Dobermann.

Manufacturing was slated to take place at the Dresden Arsenal Tank Plant, a production center owned by the government and staffed with outside contractors. This decision was made due to the fact that many of Askvig AG's own facilities had been rendered inoperable during the course of the war and were still in the process of being repaired. Production of the initial series was sluggish due to issues with quality control, especially in regards to the engine and turret rotation systems. In 1950, the Shalumite government contacted the Republic of Syara in order to acquire assistance in manufacturing the M20. Production would increase steadily over the next few years, and additional lines were brought online to handle new variants. While general production of the model by the military ended in 1967, Askvig AG continues to produce upgrade packages and spare parts in limited quantities to sustain Dobermanns fielded by state guard troops as well as foreign operators.

Variants

• M235 Scythe: Designed to primarily combat enemy attack helicopters and low-flying aircraft, the M235 is a self-propelled anti-aircraft gun equipped with dual 35mm autocannons and a 1AD21 Speer surface-to-air missile system. The armor on this model was thinned to reduce overall weight, and one set of road wheels were removed to streamline the design, and a new hydraulic system was designed for the turret to significantly increase rotation speed. The loader position in the vehicle was replaced by a radar operator whose detection equipment was mounted towards the rear of the vehicle. When fully loaded, it can carry up to 2,000 rounds of ammunition and eight anti-aircraft missiles. Its maximum engagement range is up to eight kilometers and features a maximum detection range of up to 16 kilometers in ideal conditions. It entered service in the spring of 1969.

Specialized

• M68 AVLB: armoured vehicle-launched bridge carrier with 20 meter (65 foot) scissors bridge mated to the hull in place of a turret.
• M20 ARV: armoured recovery vehicle based on the M20 chassis
• M600 CEV: A variant of the M20 outfitted for combat engineering duties. The front of the hull can be equipped with a dozer blade kit, a heavy-duty winch kit, a mine-clearing roller system, a mine flail system, or a folding A-frame crane system. The main gun was replaced by a 165mm DA-12 demolition cannon designed to fire High Explosive Squash Head (HESH) projectiles to destroy enemy fortifications and clear obstacles.
• M20DE: Designed to act as a support vehicle for combat engineering teams. A dozen blade is attached to the front of the hull, and the main canon was replaced by a boom and bucket.
• M20A1F: The coaxial machine gun was replaced by a flamethrower with an effective range of up to 120 meters (393 feet). Initial prototypes were designed to tow an armored trailer, capable of holding up to 1400 liters (370 gallons) of fuel. The production model instead removed a section of ammo stowage for the vehicle's main gun in favor of a 400 liter (105 gallon) internal fuel tank.
