A Russian author (player) publishing on the developer blog found an interesting alternative for German tier 7 light tank – the Hispano-Suiza HS 30 mit 90mm Bord K.

This light tank (or tank destroyer, depending on the classification) was built on the multipurpose HS 30 hull, developed in Switzerland by Hispano-Suiza. Several vehicles utilizing this hull were in West-German service – amongst them being the Schützenpanzer-lang IFV as well as self-propelled mortars, tank destroyers and other light vehicles. It was constructed in 1958, but this particular vehicle was not accepted in service neither in Germany nor in Switzterland. Another project, the Kanonenjagdpanzer HS 30 with the gun installed directly in frontal plate was also not successful – the Bundeswehr adopted the Raketenjagdpanzer I (also built on the HS 30 chassis) instead. The Germans didn’t scratch the cannon-armed tank destroyer idea completely, but they built it on another chassis.

Specifications:
Tank weight – 11 tons
Engine – 220-240hp
Maximum speed – 58 km/h (other sources state up to 65 km/h)
Armor thickness – 10-30mm
Armament – 90mm DEFA or Mecar

And this is how the vehicle looks now:
