The Vickers Mk.1 was a British main battle tank developed as a private project by Vickers-Armstrongs intended for export. The development began in the 1960s, using existing components or components currently under development such as the Royal Ordnance L7 105 mm gun, Leyland L60 multi-fuel engine, and FCS and transmission from the Chieftain main battle tank. In 1961, an agreement was made with India to help the country develop and produce a tank, as well as help with setting up the factory to assemble it. The Vickers Mk.1 was made to be a cheap yet effective tank appealing to the less developed countries of Africa or the Middle East. The first prototype was completed in 1963 and in 1964, one of the prototypes was sent to India, where a licensed copy of the Mk.1 called Vijayanta was produced, being the first indigenous Indian tank. 70 tanks were also sold to Kuwait, although these were modified for the desert environment including installation of tropical filters and one of the rear wheels being moved further back to decrease ground pressure for easier traversing over desert terrain.

Introduced in Update 1.69 "Regia Aeronautica", the Vickers Mk.1 can be utilized as a sniper vehicle due to its good gun depression and infamously fast reload of 5.0 sec on aced crew. However, the sight offers only 4.9-6.0x zoom, which hinders its long range performance. The mobility of the Vickers is average, and the turret armour is quite weak due to the flat gun mantlet and turret front. The hull however is angled at 60° offering moderate protection. The Vickers is best utilized as a second line vehicle, supporting more armoured allies in their effort to turn the tide of the battle to your side.
