The DF105 was a support/light tank developed between France and Germany during the 1980s by the company Thyssen Henschel. The DF105 was intended to be used only as an export vehicle and not for domestical purposes. The DF105 introduced the same gun and turret as the Austrian SK-105, and had an overall very similar design. It's design and components were also based in the French AMX-13 and German TAM, developed for Argentina. The gun was the new CN105-57 (105 mm) only found on modernized AMX-13 tanks and the already mentioned SK-105. This tank had an autoloader making good use of it's oscillating turret. The vehicle also used the same hull as the Marder I IFV and a relatively powerful powerplant. However at the end the vehicle did not evolve and stayed as a prototype due to a lack of foreign buyers.

Introduced in Update "Winged Lions", the DF105 is very lightly armoured, only having 40 mm of armour at most, but decent mobility having a 720 hp engine for its 30t weight. However, its armament is where it shines. It is equipped with a CN-105-57 cannon, with its main ammo being HEAT with 400 mm of penetration. While the shells it fires might not be the best, however it makes up by having only a 5-second reload in a 12-round first stage ammo rack. Even though its armour may be lacking it is still the hull of the Marder I IFV, this means that it would survive strafing runs from jets with 50.Cal or even 20mm cannons and it would also be enough to provide cover against autocannon shots from the front, specially from BTR-80s, Bradleys and other Marders.
