Kpz. 3 GST Turm (Germany, Tier-8, TD, premium mechanics: hydropneumatic suspension activated by a button) With the release of update 1.27.1, the Kpz. 3 GST Turm tank will be tested in a random battles by developers and supertesters.
Historical reference:
The Kpz.3 GST project existed in two versions. The first looked like a classic tank destroyer. The second, the Kpz.3 GST Turm, received a turret with limited rotation angles, in which the entire crew was located. The Kpz.3 GST was also equipped with a hydropneumatic suspension, similar in design to the Kpz.70.
The Kpz.3 was supposed to be a very fast combat vehicle, with powerful frontal armor and a high rate of fire. However, none of the projects interested the Bundeswehr command, so further developments followed the Leopard 2 line.
The german Vipera I guess
