WoT 1.28.1 Common Test: Detailed List of Changes to USSR Techtree Vehicles

This is the second (and not the last) vehicle rebalance of 2025. The rebalance affects four nearly complete branches

Along with stat changes, unnecessary modules are being removed [refinement and optimization of modules]. Get used to it—this will always be the case moving forward.

Important: Changes to shell types for SU-152 and ISU-152.
For the SU-152, the 152 mm ML-20’s premium shell has been changed from HEAT to APCR. Meanwhile, the top 122 mm D-25S gun now has both standard and premium shells changed to HEAT.
For the ISU-152, the 152 mm ML-20S standard shell has also been changed to HEAT. These changes may significantly affect gameplay alongside other stat adjustments for these vehicles.
