The Ausf K series. Medium tank, was created on November 25 and completed on December 5, 2022, with an initial design that was quite disappointing. On February 7, 2023, we began replacing some parts and updating and fixing some errors, including turning acceleration, uncontrollable speed, poor suspension, and adding a logo design. The tank is equipped with Schürzen armor in this upgrade. The tank is equipped with a main cannon of 75mm firing at a speed of 750m/s with a capacity of 90 rounds and reload time of 5 seconds. Additionally, it has 1 machine gun firing at 650m/s with a rate of fire of 6 rounds per second.The model is not patented yet, so there may be several versions that will come out.
